Butylene glycol is one of the most popular ingredients used in cosmetic and skin care products. It is colorless and viscous with the chemical formula C4H10O2. It comes in a liquid form and acts as a humectant, emollient, and solvent in formulations. Butylene glycol is the perfect ingredient for moisturizing, protecting, and conditioning the skin and hair. It also acts as a solvent and keeps the products from clamping up.

What is BUTYLENE GLYCOL used for?

Butylene glycol hydrates, conditions, and acts as a barrier to protect the skin and hair. This magical ingredient has a lot of benefits, making it quite popular in the cosmetic industry.
  • Skin care: It acts as a humectant which means that it attracts water to the upper layers of the skin and binds it there to keep the skin hydrated. It also creates a barrier on the skin to protect it from harmful surroundings
  • Hair care: It acts as a great conditioner for the hair, making it soft and flowy. This ingredient prevents water loss from the hair, thus keeping them from drying out. Further, it is also a viscosity-decreasing agent, which means that it prevents the products from sticking together and clamming up
