What is Bis-Aminopropyl Dimethicone?

Bis-Aminopropyl Dimethicone is a type of silicone that is commonly used in hair care products. It is a modified form of dimethicone, made by chemically bonding amino groups to the silicone structure, which enhances its properties for hair conditioning.

This ingredient is used for its ability to smooth hair cuticles, reduce frizz, and improve shininess. While some claim silicones can build up on the hair and require thorough cleansing, the evidence on the long-term effects is not definitive.

When you see Bis-Aminopropyl Dimethicone on a label, it indicates the product aims to provide conditioning and manageability benefits to the hair.

Scout's take

Amine-modified silicone; same siloxane microplastic precursor concerns as dimethicone with slightly better wash-out due to the amine groups. EWG 4.
