Caprylyl glycol

Caprylyl glycol suppliers and sourcing guide

Caprylyl glycol (1,2-octanediol) is a medium-chain 1,2-diol used in cosmetics and personal care products as an emollient, humectant and preservative partner, often in blends with ethylhexylglycerin, phenoxyethanol or 1,2-hexanediol. It is made synthetically from 1-octene by epoxidation and hydrolysis, or from plant-derived feedstocks such as coconut or palm. Brands buy it as a clear liquid or soft waxy solid, since it melts not far above room temperature.

Forms and grades of caprylyl glycol

Suppliers sell different products under the same name. Specify the one you need.

  • Neat, synthetic

    High-purity 1,2-octanediol from petrochemical 1-octene.

  • Plant-derived

    Caprylyl glycol from vegetable feedstocks, sold for natural-origin formulas, with feedstock documentation.

  • Preservative blends

    Blends with ethylhexylglycerin, phenoxyethanol, 1,2-hexanediol or organic acids in set ratios.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Purity (GC)
Caprylyl glycol content by gas chromatography, with isomers and related diols reported.
Water (Karl Fischer)
Water content against a low maximum.
Melting point and appearance
Melting range and appearance, which confirm identity and flag impurities.
Color
APHA color, which rises with oxidation or contamination.
Heavy metals
Lead and other metals by ICP-MS, where the supplier reports them.

Storage, lots and expiry

Storage and shelf life

Store in closed containers at room temperature, away from strong oxidizers and direct sunlight. Because it can solidify in cool warehouses, warm drums gently and mix before sampling or dosing. Shelf life follows the supplier specification, with a retest of purity and color for older stock.

Lots and expiry dates

Record purity, color and feedstock (synthetic or plant-derived) for each lot, especially if you make natural-origin or palm-related claims. Rotate stock FEFO.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

This is general information, not regulatory advice. Status differs by country and by how the ingredient is used, so check the rules for your product and market.

Frequently asked questions

What forms of caprylyl glycol can brands buy?

Common forms include neat, synthetic, plant-derived and preservative blends. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for caprylyl glycol include?

Expect purity (GC), water (Karl Fischer), melting point and appearance, color and heavy metals, each with its method, specification and result for that lot.

How should caprylyl glycol be stored?

Store in closed containers at room temperature, away from strong oxidizers and direct sunlight. Because it can solidify in cool warehouses, warm drums gently and mix before sampling or dosing. Shelf life follows the supplier specification, with a retest of purity and color for older stock.

What is the regulatory status of caprylyl glycol?

Health Canada's Natural Health Products Ingredients Database lists caprylyl glycol, with the proper name 1,2-octanediol, as a non-medicinal ingredient. The entry allows topical use as a hair-conditioning agent, antimicrobial preservative and emollient up to 5 percent. The entry also allows dental use as an antimicrobial preservative up to 1 percent.
