A safe, vegetable-based synthetic

A highly effective humectant, propylene glycol helps the skin and hair absorb and retain moisture. It also absorbs excess water in a formula, reducing bacteria growth to help your products last longer. In haircare products, it softens the hair and makes it easy to comb through.
This clear, syrupy liquid has no color, odor or taste, and is derived from vegetable oils like rapeseed or coconut. It's a synthetic liquid that's completely soluble in water, so it helps skin retain moisture.
