Propylene Glycol Dicaprylate/Dicaprate(CAS 68585-34-0)
Cosmetic Grade Propylene Glycol Dicaprylate/Dicaprate is a high-purity medium-chain composite synthetic ester refined by professional esterification and molecular distillation purification technology.
It is a high-safety multi-functional cosmetic base oil integrating emollient, moisturizing agent and solubilizer, and is a core raw material for high-standard mild skin care formulas.
Relying on the unique medium and short chain molecular structure, it balances light dry-touch skin feeling and moderate transdermal permeability, which is different from single long-chain ester or light volatile ester.
It can not only quickly smooth dry skin and form a breathable moisturizing protective film, but also efficiently solubilize essence, spices and oil-soluble active ingredients to stabilize formula uniformity.
With ultra-low irritation, excellent temperature resistance and stable chemical properties, it is friendly to sensitive skin, infant skin and fragile skin. It perfectly meets the market demand for mild, safe, refreshing and efficient cosmetic raw materials, and is widely used in high-end mild skin care and safe daily cosmetic mass production.
