Emulsifiers & Preservatives

Emulsifiers and preservatives play crucial roles in the formulation and stability of cosmetics like creams and lotions.

Emulsifiers are chemicals that help stabilize emulsions, which are mixtures of two or more immiscible liquids (like oil and water) that are held together in a stable state. In cosmetics, emulsifiers ensure that the water and oil phases remain mixed together, preventing separation. Common emulsifiers include surfactants like polysorbates, glyceryl stearate, and cetearyl alcohol.
