Understanding PEG-8 Glyceryl Isostearate in Cleansing Formulas

PEG-8 Glyceryl Isostearate is an ingredient commonly used in cleansing balms and cleansing oils. Its primary function is to act as a makeup remover and an emulsifier, helping to dissolve makeup and allowing the oil-based cleanser to mix with water and rinse off cleanly.

Substitutes and Necessity

Yes, you can use alternative ingredients depending on the type of cleansing product you are formulating:

• For Cleansing Water or Wash-off Formulas: As the staff suggested, MakeUp-Wash (PEG-6 Caprylic/Capric Glycerides) is an excellent, gentle alternative. It works by forming micelles in water to capture and remove makeup.
• For Cleansing Oil Formulas: Oilsify 15 (POE(20) Glyceryl Triisostearate), which was linked in your original post, is another effective oil-soluble emulsifier specifically designed for cleansing oils to help them rinse off with water.

Whether an ingredient like PEG-8 Glyceryl Isostearate or its substitutes is necessary depends on your desired product type. If you are creating a rinse-off cleansing oil or balm, an emulsifier is crucial for the product to effectively wash away with water, taking the dissolved makeup and impurities with it. If you are making a simple oil cleanser meant to be wiped off with a cloth, an emulsifier might not be strictly required, but for rinse-off products, it is essential for performance.
