PEG-3 SORBITAN TRISTEARATE

Safety grade: A

This is a man-made helper ingredient made by combining plant-based stearic acid (a natural fat) with other chemicals. It works like a bridge between water and oil, allowing them to mix smoothly together in creams and lotions.

This emulsifier helps blend water and oil-based ingredients together so they stay mixed in the product instead of separating into layers.

Graded using: COSING.
