Product Description

What is Caprylyl Glycol?

Caprylyl Glycol is a diol built on an eight-carbon (octane) chain, with hydroxyl groups at the 1 and 2 positions — hence its systematic name, 1,2-octanediol. That combination of a moderately long hydrophobic chain and two polar hydroxyl groups gives it useful skin-conditioning and humectant properties, while its mild antimicrobial-boosting character has made it a standard ingredient supporting preservative efficacy in modern cosmetic formulations. The Cosmetic Ingredient Review panel has evaluated it as safe for cosmetic use across a wide concentration range.

Uses of Caprylyl Glycol

Formulators use Caprylyl Glycol primarily as a humectant and skin-conditioning agent in moisturizers, cleansers, and sunscreens, where it helps the finished product feel smoother and retain moisture. It’s also commonly paired with other preservative or antimicrobial ingredients to boost overall system effectiveness, which is why it shows up frequently in paraben-free and “gentle” formulation lines.

FAQs: Caprylyl Glycol (1,2-Octanediol)

It's used as a humectant, skin-conditioning agent, and preservative booster in cosmetic and personal-care formulations, including moisturizers, cleansers, and sunscreens.

Yes — 1,2-octanediol is the systematic chemical name; caprylyl glycol is the more common cosmetic-industry (INCI-style) name for the same compound.

The Cosmetic Ingredient Review panel has evaluated caprylyl glycol as safe for cosmetic use across a wide concentration range; it's classified as a mild eye irritant (H319) at the raw-material stage, so standard PPE is recommended during handling.

1117-86-8, C8H18O2, molecular weight approximately 146.23 g/mol.

Yes, for every lot (SKU S3078), so formulators can confirm identity and purity before use.
