Butylene glycol and propylene glycol are organic chemicals commonly used in various skin care products.

Butanediol is an ingredient that has a water-absorbing molecular formula. It is super powerful in hydrating and moisturizing, refreshing, non-sticky, and has very good hydrating and moisturizing safety properties. It is often found in skin care products.
