Isododecane, Cosmetic Volatile Solvent(CAS 31807-55-1)
Cosmetic Grade Iso-Dodecane is a high-purity synthetic branched volatile isoparaffin solvent, specially developed for high-end dry-touch and long-wear waterproof cosmetic formulas. Adopting advanced hydrogenation purification process, it removes impurities and unstable components, retaining pure and stable alkane structure.
With unique balanced volatility, it can volatilize slowly and evenly during product application without residue on the skin surface, perfectly presenting a delicate matte dry-touch feeling. It has excellent oil solubility and dispersibility, which can effectively dissolve various lipophilic active ingredients and colorants, improve formula uniformity and fineness.
Different from silicone oil and mineral oil that are easy to accumulate and cause heavy skin feel, Iso-Dodecane has zero residue and zero burden, non-comedogenic and non-irritating. It can significantly enhance the waterproof and smudge-resistant performance of makeup products, prolong makeup lasting time, and is an indispensable universal base solvent for modern high-grade matte long-wear cosmetics.
