What Glyceryl Caprylate does

Softens and conditions the skin
Helps boost preservative performance
Helps oil and water stay blended

Glyceryl Caprylate is made by joining glycerin with caprylic acid, a fatty acid that occurs naturally in coconut and palm kernel oils. The result is a mild ester that blends into both water-based and oil-based products. Chemists value it because it is gentle and works well with a wide range of other ingredients.

Formulators use it mainly to condition skin, which means it helps skin feel soft and smooth. It also helps protect a product from microbes, so it is often paired with other preservatives. In a finished lotion or cleanser, it feels light and slightly silky, and it spreads easily without a heavy film.

Good for

Suits gentle everyday formulas, including baby lotions, moisturizers and cleansers, where a light, mild feel is wanted.

Be careful if

Nothing in particular for most skin types.

Frequently asked questions

Is Glyceryl Caprylate safe for babies?

It is widely used in baby lotions and is considered mild. Any product can still irritate some skin, so do a small patch test first. If your baby has a rash or eczema, check with your pediatrician before using a new product.

Is Glyceryl Caprylate the same as caprylic acid?

No. Caprylic acid is the fatty acid. Glyceryl Caprylate is the ester formed when that acid bonds with glycerin. The bonded form behaves differently. It blends more easily into creams and lotions, which is why formulators choose it for smooth, light products.
