Je bent trots op het resultaat. Maar na twee weken open je het potje en zie je een vreemd, pluizig plekje op het oppervlak of ruik je dat de geur is veranderd van fris naar muf. Het is de nachtmerrie van elke maker: bederf.<\/p>\n\n<p class=\"wp-block-paragraph\">Zelf cosmetica maken is een fantastische manier om precies te bepalen wat je op je huid smeert, maar het brengt ook een grote verantwoordelijkheid met zich mee. In tegenstelling tot commerci\u00eble producten die vol zitten met zware chemische stabilisatoren, zijn jouw natuurlijke creaties kwetsbaar. Om te zorgen dat je lotion, serum of mascara veilig blijft om te gebruiken, moet je begrijpen hoe houdbaarheid werkt, waarom pH-waardes tellen en welke bewaarmethoden echt werken.<\/p>\n\n<h2 class=\"wp-block-heading\">Waarom bederft cosmetica eigenlijk?<\/h2>\n\n<p class=\"wp-block-paragraph\">Het klinkt simpel, maar de grootste vijand van houdbaarheid is vaak het ingredi\u00ebnt waar we het meest van houden: water. Bacteri\u00ebn, schimmels en gisten hebben drie dingen nodig om te overleven en zich te vermenigvuldigen: voeding, een aangename temperatuur en water. Zodra je water toevoegt aan een formulering, zoals bij lotions, cr\u00e8mes, toners of douchegels, cre\u00eber je in feite een zwembad voor micro-organismen. Zonder de juiste maatregelen vermenigvuldigen deze ongewenste gasten zich razendsnel, zelfs als je ze nog niet met het blote oog ziet.<\/p>\n\n<p class=\"wp-block-paragraph\">Er is een groot verschil in risico tussen producten op oliebasis en producten op waterbasis. Watervrije producten, ook wel anhydrous genoemd, zijn bijvoorbeeld lippenbalsems, body butters zonder water of massageoli\u00ebn. Omdat hier geen water in zit, kunnen bacteri\u00ebn er moeilijk in groeien. Ze kunnen wel ranzig worden door oxidatie, maar dat is een ander proces dan microbi\u00eble groei. Zodra je echter <a href=\"https:\/\/www.youwish.nl\/zeepwinkel\/cosmetica\/lotion-maken\/\">lotion gaat maken<\/a> waarbij je water en olie mengt tot een emulsie, is de kans op bederf direct aanwezig. Hier is een goed conserveringssysteem geen optie, maar een noodzaak.<\/p>\n\n<p class=\"wp-block-paragraph\">Om het risico op besmetting direct bij de bron aan te pakken, gebruik je nooit kraanwater. Kraanwater bevat van zichzelf al mineralen en micro-organismen die je product kunnen destabiliseren. Gebruik daarom altijd gedestilleerd water.<\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-42148 status-publish first instock product_cat-aromaterapia product_cat-ayudas-y-recursos product_cat-base-de-pulverizacion product_cat-hacer-jabon product_cat-hacer-locion product_cat-hacer-rimel product_cat-jabon-de-proceso-en-frio product_cat-materias-primas-es product_cat-materias-primas-es-2 product_cat-materias-primas product_cat-productos-cosmeticos product_cat-spray-para-habitaciones-y-lino product_tag-agua-destilada has-post-thumbnail taxable shipping-taxable purchasable product-type-variable has-default-attributes\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"42139\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"42139\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/agua-destilada\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/agua-destilada\/\" title=\"Agua destilada\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2021\/05\/gedemineraliseerd-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"Agua desmineralizada\" sizes=\"(max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/agua-destilada\/\" aria-label=\"Agua destilada\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">Agua destilada<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>2.25<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>1.86<\/bdi><\/span><\/span><\/span> <span aria-hidden=\"true\">-<\/span> <span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>9.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>8.22<\/bdi><\/span><\/span><\/span><span class=\"screen-reader-text\">Rango de precios: desde &euro;2.25&euro;1.86 hasta &euro;9.95&euro;8.22<\/span> <small class=\"woocommerce-price-suffix\">incl.

De zuurgraad, oftewel de pH-waarde, is hierbij cruciaal. De meeste bacteri\u00ebn groeien het best bij een neutrale pH rond de 7. Onze huid is echter licht zuur, meestal tussen de 4,5 en 5,5. Als je een cr\u00e8me maakt, wil je dat de pH-waarde huidvriendelijk is, maar ook dat deze binnen het bereik valt waarin je conserveermiddel effectief werkt. Als de pH te hoog of te laag is, kan je conserveermiddel onwerkzaam worden, waardoor je product alsnog onbeschermd is. Het meten van de pH is de enige manier om zeker te weten dat je product stabiel is.<\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-317813 status-publish first instock product_cat-taza-de-medir product_cat-productos-cosmeticos product_cat-hacer-locion product_cat-greedschap-es product_cat-embalaje has-post-thumbnail sale taxable shipping-taxable purchasable product-type-simple\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"317076\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"317076\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/productos-cosmeticos\/hacer-locion\/greedschap-es\/ph-metro-digital\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/productos-cosmeticos\/hacer-locion\/greedschap-es\/ph-metro-digital\/\" title=\"pH-metro digital\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><span class=\"sale-item product-label type-bubble\">-13%<\/span><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2024\/12\/ph-meter-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"pH-meter\" sizes=\"(max-width: 360px) 147px, \" \/><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2024\/12\/ph-meter-2-300x360.jpg\" class=\"gallery-image\" alt=\"ph-meter-2\" loading=\"lazy\" sizes=\"auto, (max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><div class=\"shoptimizer-plp-carousel--pagination\">\n      \t\t\t<span class=\"shoptimizer-plp-carousel--dot active\"><\/span>\n      \t\t\t<span class=\"shoptimizer-plp-carousel--dot\"><\/span>\n    \t\t<\/div><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/es\/comprar\/productos-cosmeticos\/hacer-locion\/greedschap-es\/ph-metro-digital\/\" aria-label=\"pH-metro digital\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">pH-metro digital<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><del aria-hidden=\"true\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>14.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>12.36<\/bdi><\/span><\/span><\/span><\/del> <span class=\"screen-reader-text\">El precio original era: &euro;14.95&euro;12.36.<\/span><ins aria-hidden=\"true\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>12.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>10.70<\/bdi><\/span><\/span><\/span><\/ins><span class=\"screen-reader-text\">El precio actual es: &euro;12.95&euro;10.70.<\/span> <small class=\"woocommerce-price-suffix\">incl.

Je kunt het beste recept hebben, maar als je werkt met vieze materialen, ben je nergens. Microben komen niet alleen uit de lucht, maar vooral van je handen en gereedschappen. Voordat je begint, moeten je werkblad, mengkommen, lepels en verpakkingen ontsmet worden. Alcohol (70% of 96%) werkt hier perfect voor. Probeer daarnaast de binnenkant van potjes en de ingredi\u00ebnten zo min mogelijk met je vingers aan te raken tijdens het proces.<\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-140772 status-publish first instock product_cat-hacer-jabon product_cat-jabon-de-proceso-en-frio product_cat-ayudas-y-recursos product_cat-verter-jabon product_cat-ingredientes-de-bano-efervescente product_cat-productos-cosmeticos product_cat-hacer-locion product_cat-conservantes product_cat-materias-primas-es has-post-thumbnail taxable shipping-taxable purchasable product-type-variable has-default-attributes\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"140742\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"140742\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/alcohol-etanol-96\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/alcohol-etanol-96\/\" title=\"Alcohol &#8211; Etanol 96% &#8211; Cetonato desnaturalizado\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2021\/05\/sprayalcohol-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"Alcohol - Etanol 96% - Cetonato desnaturalizado\" sizes=\"(max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/alcohol-etanol-96\/\" aria-label=\"Alcohol &#8211; Etanol 96% &#8211; Cetonato desnaturalizado\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">Alcohol &#8211; Etanol 96% &#8211; Cetonato desnaturalizado<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>3.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>3.26<\/bdi><\/span><\/span><\/span> <span aria-hidden=\"true\">-<\/span> <span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>59.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>49.55<\/bdi><\/span><\/span><\/span><span class=\"screen-reader-text\">Rango de precios: desde &euro;3.95&euro;3.26 hasta &euro;59.95&euro;49.55<\/span> <small class=\"woocommerce-price-suffix\">incl.

Dit is onjuist. Vitamine E is een antioxidant. Het voorkomt dat oli\u00ebn ranzig worden door oxidatie, maar het doodt geen bacteri\u00ebn of schimmels. Als je product water bevat, heb je een <a href=\"https:\/\/www.youwish.nl\/zeepwinkel\/cosmetica\/lotion-maken\/conserveringsmiddelen\/\">breed-spectrum conserveermiddel<\/a> nodig. Dit beschermt tegen bacteri\u00ebn, gisten \u00e9n schimmels.<\/p>\n\n<p class=\"wp-block-paragraph\">Welk middel je kiest, hangt af van je ingredi\u00ebnten en de gewenste uitstraling van je product. Fenoxyethanol is een betrouwbare, synthetische optie die veel gebruikt wordt omdat het zeer stabiel is. Natriumbenzoaat wordt vaak gebruikt in combinatie met kaliumsorbaat in &#8216;natuurlijkere&#8217; formuleringen, maar werkt alleen goed bij een lagere pH (onder de 5,5). Zonder een van deze middelen is een product met water slechts enkele dagen houdbaar in de koelkast.<\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-230133 status-publish first instock product_cat-ayudas-y-recursos product_cat-conservantes product_cat-cuidado-de-los-labios product_cat-hacer-efervescencia-en-el-bano product_cat-hacer-jabon product_cat-hacer-locion product_cat-hacer-rimel product_cat-jabon-de-proceso-en-frio product_cat-materias-primas product_cat-materias-primas-es product_cat-productos-cosmeticos product_tag-conservante-es product_tag-fenoxietanol product_tag-fenoxietanol-es has-post-thumbnail taxable shipping-taxable purchasable product-type-variable has-default-attributes\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"230028\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"230028\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/conservante-fenoxietanol-fenoxietanol\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/conservante-fenoxietanol-fenoxietanol\/\" title=\"Fenoxietanol &#8211; Conservante\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2023\/07\/transparentoils-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"Fenoxyethanol - Phenoxyethanol - Conserveermiddel\" sizes=\"(max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/es\/comprar\/hacer-jabon\/jabon-de-proceso-en-frio\/ayudas-y-recursos\/conservante-fenoxietanol-fenoxietanol\/\" aria-label=\"Fenoxietanol &#8211; Conservante\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">Fenoxietanol &#8211; Conservante<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>3.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>3.26<\/bdi><\/span><\/span><\/span> <span aria-hidden=\"true\">-<\/span> <span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>115.95<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>95.83<\/bdi><\/span><\/span><\/span><span class=\"screen-reader-text\">Rango de precios: desde &euro;3.95&euro;3.26 hasta &euro;115.95&euro;95.83<\/span> <small class=\"woocommerce-price-suffix\">incl.

Las opciones se pueden elegir en la p\u00e1gina de producto\t<\/span>\n<\/div><\/li>\n<\/ul>\n<\/div>\n\n<h2 class=\"wp-block-heading\">Verpakking: Potjes versus pompjes<\/h2>\n\n<p class=\"wp-block-paragraph\">De manier waarop je je product bewaart, heeft direct invloed op de levensduur. Een open pot waar je elke dag met je vingers in dipt, introduceert telkens nieuwe bacteri\u00ebn. Voor cr\u00e8mes en lotions is een pompflacon of een airless dispenser veel hygi\u00ebnischer. De inhoud komt niet in contact met lucht of vingers totdat het uit de flacon komt. Maak je toch gebruik van potjes? Zorg dan dat je een spatel gebruikt om het product eruit te halen, in plaats van je vingers. Voor gevoelige producten zoals oogmake-up is de verpakking nog kritischer. Omdat ogen extra gevoelig zijn voor infecties, wil je hier elk risico uitsluiten, zoals beschreven bij onze <a href=\"https:\/\/www.youwish.nl\/zeepwinkel\/cosmetica\/mascara-maken\/verpakkingen-3\/\">mascara verpakkingen<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\">Moet mijn cosmetica in de koelkast?<\/h2>\n\n<p class=\"wp-block-paragraph\">Veel mensen denken dat \u00abnatuurlijk\u00bb betekent dat het in de koelkast moet, net als verse melk. Dat is echter niet altijd waar en soms zelfs nadelig. De meeste correct geformuleerde cr\u00e8mes en lotions zijn stabiel bij kamertemperatuur, mits bewaard op een koele, donkere plek. De koelkast kan zorgen voor condensvorming in de verpakking, wat extra water introduceert en schimmelgroei kan bevorderen. Daarnaast kunnen oli\u00ebn en wassen hard worden of kristalliseren door de kou, wat de textuur van je emulsie verpest.<\/p>\n\n<p class=\"wp-block-paragraph\">Er zijn uitzonderingen. Producten zonder conserveermiddelen die bedoeld zijn voor direct gebruik, zoals een vers masker met fruit, moeten absoluut in de koelkast en binnen enkele dagen gebruikt worden. Ook producten met zeer instabiele actieve stoffen of pure hydrosolen kunnen baat hebben bij koeling. De beste bewaarplek voor de meeste <a href=\"https:\/\/www.youwish.nl\/zeepwinkel\/cosmetica\/\">cosmetica<\/a> blijft echter een droge kast buiten direct zonlicht. Zet je kostbare potjes dus liever niet in de vensterbank van een vochtige, warme badkamer.<\/p>\n\n<h2 class=\"wp-block-heading\">Hoe herken je bederf?<\/h2>\n\n<p class=\"wp-block-paragraph\">Twijfel je of je zelfgemaakte product nog goed is? Vertrouw op je zintuigen, maar wees streng. Let allereerst op de geur. Als het product zurig ruikt, ranzig (zoals oude krijtjes) of gewoon anders dan toen je het maakte, moet je het weggooien. Kijk ook goed naar de kleur. Verkleuringen, donkere randjes of vreemde vlekken kunnen wijzen op oxidatie of schimmel.<\/p>\n\n<p class=\"wp-block-paragraph\">Controleer de textuur. Is de emulsie gescheiden en ligt er een laagje water of olie op? Hoewel dit soms &#8216;gewoon&#8217; instabiliteit is, is een gescheiden product niet meer veilig omdat het conserveermiddel niet meer gelijkmatig verdeeld is. En als je zwarte of groene puntjes ziet, schep dit er dan nooit af. De onzichtbare schimmeldraden zitten vaak al door het hele product.<\/p>\n\n<p class=\"wp-block-paragraph\">Voor wie producten professioneel wil gaan verkopen, is gokken geen optie. Je bent dan verplicht om de veiligheid te garanderen. In dat geval zijn professionele <a href=\"https:\/\/www.youwish.nl\/zeepwinkel\/services\/laboratorium-tests\/\">laboratorium tests<\/a> nodig om de exacte houdbaarheid en microbi\u00eble stabiliteit vast te stellen.<\/p>\n\n<p class=\"wp-block-paragraph\">Je eigen verzorgingsproducten maken is een prachtig proces. Door schoon te werken, de juiste <a href=\"https:\/\/www.youwish.nl\/belangrijke-veiligheids-informatie\/\">veiligheidsinformatie<\/a> in acht te nemen en conservering serieus te nemen, kun je genieten van luxe producten zonder je zorgen te maken. Begin met schone materialen, meet je pH en kies de juiste verpakking. Zo blijft jouw zelfgemaakte cosmetica niet alleen fijn voor je huid, maar ook veilig in de pot.
