Caprylyl glycol

CAS No-1117-86-8

Caprylyl glycol is an alcohol derived from caprylic acid, which is found naturally found in palm and coconut oils. Formulators love it for a few different reasons: One, it improves the spreadability and ultimately the feel of a product on your skin. Two, because it’s antimicrobial, and it has preservative-like properties, says Belkin. “It is a multifunctional cosmetic ingredient that can replace traditional preservatives, such as parabens or formaldehyde releasers,” he says. Similarly, it actually makes other preservatives work better; caprylyl glycol has been shown to increase the antimicrobial activity of other preservatives, says Palep. As such, it “acts as a stabilizer to boost shelf life and helps prevent other ingredients from spoiling,” says Palep.While cosmetic chemists love the ingredient for its formulation benefits, the benefits to skin are limited. Caprylyl glycol is a humectant, meaning it’s a substance that helps the skin retain water.2 “Humectants are used in the formulation of lotions, moisturizers, and cleansers in order to help lock in moisture,” explains Solomon. “This is important to prevent dry skin while also slowing down signs of aging. As the skin loses moisture, we begin to see more lines, wrinkles, and sagging. Using skincare products with caprylyl glycol can help attract moisture to the skin, resulting in a smoother, softer complexion with decreased wrinkles and a more plump appearance.”
