This is a gentle helper ingredient made by combining plant-derived oils with a type of sugar-like substance. It works behind the scenes to help blend ingredients together that normally don't mix well, like oil and water.

This emulsifier helps cosmetic products stay smooth and stable by allowing oil and water-based ingredients to mix together seamlessly, preventing separation and improving product texture and appearance.
