Usage

Cyclopentasiloxane/ Cyclomethicone/ Decamethylcyclopentasiloxane (D5) is widely used in skincare products, cosmetics, hair care products, and antiperspirants as a volatile solvent or carrier. It helps active ingredients distribute evenly, evaporates quickly after application to provide a fresh, non-greasy feel, and imparts a smooth texture to products.

Key Features:

1. Volatility: Forms a temporary film on the skin or surface and then evaporates, leaving no residue.

2. Hydrophobicity: Can provide a water-repellent effect.

Compatibility: Miscible with various organic ingredients, stabilizing formulations.
