Polysorbate 80 is one of the most important but least discussed ingredients in the world of cosmetics making and DIY cosmetics. It is that little thing that keeps oil and water from conflicting. Every maker needs it at some point. Understanding how to use polysorbate 80 can transform your bath oils, sprays, scrubs and lotions from simple experiments into stable, professional-quality products.
In this guide, you will learn what polysorbate 80 is, why it is important and how to use it properly in both soap making and cosmetics, including the proper soap making supplies.
What is polysorbate 80?
Sorbitol (a natural sugar alcohol) and oleic acid (which comes from plants) are the two main ingredients in polysorbate 80, a nonionic emulsifier and solvent. The main thing it does is help oils mix evenly with water, which they cannot do on their own. Because it can make oils and water work together, it is an important ingredient in many soaps and cosmetics.
Polysorbate 80 is used in both professional and DIY cosmetics to make them look and feel better and to prevent them from flaking. Without this ingredient, light mists or emulsions might look cloudy and bath oils might leave a greasy film on the water. Polysorbate 80 keeps these products stable so that each ingredient works as it should.
You can often find it in:
- Body sprays, facial toners and mists for the room
- Bath oils and bath products that lather
- Body scrubs, whipped soap and body scrubs
- Creams, lotions and other emulsified products
In short, it is one of those silent helpers in your soap-making supplies that makes everything look good and work well.
Why it matters in DIY cosmetics
When making DIY cosmetics, stability is essential. You may notice that freshly made products look beautiful at first, but begin to separate after a few days. This is because oil and water naturally repel each other. Polysorbate 80 bridges that gap and keeps your formulas intact for weeks or even months.
It also makes your products feel more comfortable on the skin. By dispersing oils evenly, Polysorbate 80 gives lotions a light, silky texture and helps bath oils wash away cleanly. It also prevents concentrated essential oils from reaching the skin directly, a small but important step for safety and comfort. For makers who want their creations to look polished, smell balanced and feel professional, Polysorbate 80 is one of the most valuable tools in cosmetic making.
Using Polysorbate 80 when making soap
When making soap, Polysorbate 80 has several benefits. It helps spread color and fragrance evenly, prevents oil from separating in scrubs and makes your product work better in water. It works best in products such as pouring soaps, bath oils and exfoliating scrubs, where stability and even mixing are very important.
If you add Polysorbate 80 to pouring soap, you should use about 1-3% of the total weight of the base. Mix it well after melting, but before pouring. This keeps your colors even and prevents fragrance oils from leaking out over time. It keeps oils from just floating on the surface of bath oils and bubble balls. For a light dispersion, use equal parts oil and Polysorbate 80. For a milky, fully emulsified result, use 2:1. That means no slippery residue will remain in the bathtub and you’ll have a clean, even bath.
Polysorbate 80 holds the oils in scrubs or whipped soap together with the exfoliants, keeping them from disintegrating and allowing the product to be rinsed off cleanly. The result is a smooth, non-greasy finish that keeps skin soft and hydrated.
Recommended use amounts
The right balance of Polysorbate 80 depends on the type of product you are making. There is no formula that works for everything, but a few general guidelines can help you get a stable, working result.
For bath oils, Polysorbate 80 is usually used in a ratio of 1:1 to 2:1 with the oil. A 1:1 ratio provides a light diffusion, while a 2:1 ratio creates a milky bath that does not leave a greasy residue. In room or body sprays, the content is usually between 10% and 20%, depending on the fragrance load. This helps your oils mix evenly with water for a clear, stable mist.
When working with cast soap, 1-3% is usually sufficient to prevent perspiration and ensure that the scent remains consistent throughout the soap. For sugar or salt scrubs, 1-5% is ideal: it prevents the oils from separating and improves rinsing, leaving the skin soft rather than greasy. In lotions and creams, you can use between 2% and 6%. At these concentrations, Polysorbate 80 helps emulsify and provides a smooth, even texture. These percentages are not strict rules, but flexible guidelines. Each formula behaves slightly differently depending on the type of oils, butters and fragrances you use. The best approach is to start small, take notes and adjust your percentages gradually. Over time, you’ll find the perfect balance that suits both your ingredients and your personal preferences.
Tips for best results
If you work with Polysorbate 80, accuracy makes a big difference. Here are some tips from people who have made formulas before:
- Mix it with oils first. Always mix Polysorbate 80 with your oils before adding water. This step makes the emulsions smoother.
- Avoid high temperatures. Mix on moderate heat, as too much heat can make it less effective.
- Get the right dimensions. Even small changes can change the feel and function of your product.
- Store it properly. To make it keep longer, store it tightly sealed in a cool, dry place.
- Try out each new mix. The best way to learn over time how to make things is to write down your proportions and results.
If you consider Polysorbate 80 as more than just a functional ingredient and include it in your creative process, you will see how it adds texture and shine to your products.
Common mistakes to avoid
A few small missteps can affect your bottom line:
- Add Polysorbate 80 too late in the process. Always add it before emulsifying.
- Use it only in thick creams without a supporting emulsifier.
- Skipping stability tests when adding new fragrances or essential oils.
By avoiding these mistakes, you save time and ingredients and ensure that your DIY cosmetics look and feel consistent from batch to batch.
Frequently asked questions (FAQ)
V1. Is Polysorbate 80 a natural substance?
Polysorbate 80 is derived from vegetable sorbitol and fatty acids, but must be processed to work as an emulsifier. It is considered safe, breaks down naturally and is suitable for both home and professional cosmetic making.
V2. Can polysorbate 80 be used in all cosmetic products?
You can use it in many different products, such as sprays, bath oils, scrubs and lotions. But it is not the best choice for cold-pressed soap, as its high pH can make it less effective.
V3. How much polysorbate 80 should I put in my formula?
How much you use depends on the type of product you have. For example, try a 1:1 ratio of oil to water in bath oils, and a 2-6% ratio in lotions and creams. Always start with a small amount and note your results before moving on to larger amounts.
V4. What is the difference between polysorbate 80 and polysorbate 20?
Both are emulsifiers, but polysorbate 80 works better with thicker oils such as castor or coconut oil, while polysorbate 20 is better for light, delicate fragrances. Many soap-making kits contain both substances for different uses.
V5. Do I need to add a preservative to Polysorbate 80?
Yes, preservatives prevent microbes from growing in your formula if it contains water. Polysorbate 80 helps with mixing and texture, but by itself does not keep ingredients fresh.
