INCI name

Panthenol

Also listed as: Provitamin B5, dexpanthenol

Panthenol is the alcohol form of pantothenic acid (vitamin B5). Skin and hair enzymes can convert it to the vitamin. In products it is used as a humectant and a conditioning agent, especially in hair conditioners, after-sun lotions and after-shave products.

It is usually made synthetically. D-panthenol (dexpanthenol) is the form that the body can convert; the INCI name on a pack is still often just Panthenol.

Where it turns up

Hair conditioners, shampoos, after-sun lotions, after-shaves and moisturisers.

Sensitivities

Usually well tolerated. Contact allergy is uncommon.

Vegan or animal-derived

Typically synthetic, so usually vegan. Confirm if you need to be sure.
