Butylparaben

Other name: Butylparaben; butyl parahydroxybenzoate

Function: Masking, Fragrance, Preservative

1. Definition Butylparaben:

Butylparaben is a type of paraben, which is a preservative commonly used in cosmetics and personal care products to prevent the growth of bacteria, fungi, and other microorganisms.
