What it is
1,10-Decanediol is a symmetrical diol with hydroxyl groups at both ends of a ten-carbon chain. In formulations it acts as a conditioning agent and can contribute to a smooth skin feel, and diols of this type are sometimes included to support a formula's overall freshness and stability. It is oil- and water-compatible enough to blend into a range of emulsion bases.
Safety & warnings
1,10-Decanediol is used at low levels in cosmetics and is generally well tolerated. It is not a recognized fragrance allergen.
Origin & sourcing
A synthetically produced organic diol. It is a defined chemical compound rather than a plant or animal derived material.
