Question

Can I use `Glyceryl Stearate SE / Glyceryl Monostearate SE` and `Cetyl Alcohol` to replace `Light Cream Maker` in a sunscreen cream formula? Will this substitution affect the formula's stability and texture, potentially causing phase separation?

Answer

Regarding your question about replacing Light Cream Maker with Glyceryl Stearate SE / Glyceryl Monostearate SE and Cetyl Alcohol in your sunscreen formula:

Glyceryl Stearate SE / Glyceryl Monostearate SE and Cetyl Alcohol are typically used to increase the thickness and richness of a cream, but they are not primary emulsifiers on their own for this type of formula.

To create a stable emulsion using Glyceryl Stearate SE / Glyceryl Monostearate SE and Cetyl Alcohol, you would generally need a primary emulsifier, such as Soft Cream Maker. Without a proper emulsifier like Soft Cream Maker, the formula is likely to separate.

Therefore, you cannot directly substitute Light Cream Maker with just Glyceryl Stearate SE / Glyceryl Monostearate SE and Cetyl Alcohol and expect a stable cream.
