Know Your Ingredients: Panthenol

by beautifulwithbrains


What is it
Panthenol is a provitamin derived from pantothenic acid (Vitamin B5) and alcohol. A provitamin is a substance that is converted into a vitamin (vitamin B5 in this case) inside a living cell.

What it does
Panthenol is a humectant: it draws water from the environment into skin, hair and nails, thus helping to keep them hydrated.
In addition, it can improve signs of aging, such as hyperpigmentation and redness
When used in hair care products, it can also reduce hair breakage.

Side effects
Panthenol can cause contact dermatitis in some people.

Kassy, I don’t think it does. So far, I haven’t seen any studies confirming this claim.

Is Panthenol sometimes obtained from Avocado? Because I’m concerned about Avocado being in products I use due to allergies.
By the way, thank you for this helpful website!

ChrisCross, I’m sorry you are allergic to avocado. I’m afraid I don’t know if Panthenol is obtained by avocado. I did a search but all I found is that it is obtained by plants. Sorry I couldn’t be of more help.

Thank you anyway for your help – I guess I’ll just avoid suspicious ingredients, as well as do skin tests before using anything that close to my throat (like shampoo).
Keep up the great work on your site!

ChrisCross, you’re welcome. Doing skin tests is definitely a good idea. And thanks!

I have an allergie to Panthenol, fist it was to a cream and now it is to a hairproduct.
It is difficult to avoid this product

Alice, I’m sorry to hear that. It is in so many products that beauty shopping must be frustrating for you.

Is panthenol a homone or anything like a homone

Gio April 8, 2018 - 5:12 pm

Carol, no, it’s an alcohol.

Laurie April 6, 2018 - 6:49 pm

I used Keratin Plus for the first time which has panthenol and now my scalp feels like it is on fire!

Laurie, oh no! So sorry to hear that! Are you sure it’s Panthenol and not something else in there that’s causing the problem?
