Know Your Ingredients: Octyldodecanol

by Gio


What it is
Octyldodecanol, a long-chain fatty alcohol, is a clear liquid.

What it does
Octyldodecanol is very used in moisturizers and lotions for two reasons. Its emollient and lubricating properties give skin a soft feel. In addition, it helps to form emulsions and prevents the oil and liquid components of a formula from separating.
It also acts as an anti-foaming agent, helping reduce the tendency of products to produce foam when they are shaken.

Side effects
Octyldodecanol can cause irritations, but it’s rare.

Thanks for the information Gio. As for the irritaions, does that apply on the amount of Octyldodecanol or does it not matter?

HI, Fatty alcohol’s like Phenoxyethanol and the Octyldodecanol cause me to break out. I have oily and acne-prone skin and reading online reviews from all sorts of organic and natural products, people keep saying that this ingredient will break you out. My question is, Is this true for the Octyldodecanol?

Christina, I don’t think it is. I’ve never had problems with it and I could find no proof in the scientific literature that it causes breakouts.

Per the EWG website, octyldodecanol is listed as a potential irritant for products used around the eyes and on the skin. I learned this the hard way, after having a reaction to Drunk Elephant’s Shaba Complex Eye Serum, which lists octyldodecanol as the second ingredient. My allergic reaction built up over time, occurring during my second bottle of Shaba.

Greta, I’m sorry this happened to you. Unfortunately, everything could potentially cause an allergic reaction in someone. 🙁

Dee, you’re welcome. It depends on the amount too. Usually Octydodecanol is used in very small concentrations in cosmetics and skincare products so it shouldn’t be irritating. But if one is very sensitive to the ingredient I guess even small concentrations may be enough to irritate skin. But that is really rare.

I am applying Clotrimazole USP, 1 % to my split corners of my mouth. Now I have red itchy bumps on my chin. I am highly allergic to Vit E on my skin, but could the Octyldodecano ingredient be aggravating my skin. I am not sure if the Clotrimazole has vit. E in it.

Beverly, split corners of your mouth are a sign of B vitamin deficiency. Visit a health food store the next time this is a problem and ask them for a high-quality B complex supplement.

beverly, split corners are a sign of GAPS. Gut and Physiology Syndrome.

There are more causes than vitamin deficiency for your symptoms, to beging with you don’t say if you wear dentures or not? Poor fitting teeth or dental problems can also cause the corners of the mouth to split. Plus I’ve read that the ingredient can cause the reaction of other irritating ingredients to be intensified. So it’s not just about how that ingredient behaves but how it interacts with others.

Hi Beverly. Well, that’s hard to say. Everyone’s skin is different and each ingredient in any product could potentially cause an irritation to someone. If you have used products with Octydodecanol before and they didn’t give you problems, it’s unlikely that’s the cause. If, on the other hand, this is your first time using Octydodecanol, that’s what could be aggravating your condition. But unless you consult a dermatologist there’s no way to know for sure. Clotrimazole USP, 1 % shouldn’t contain any Vitamin E, though.

Is Octyldodecanol derived from beeswax

beautifulwithbrains November 6, 2011 - 9:15 pm

Sharn, it can be derived from beeswax esters, yes.

I know this article is really old, but recently I had a skincare consult from a lady who owns a skincare company and she went through all ingredients in my current products. She told me that OCTYLDODECANOL is a sunscreen ingredient that was hiding in my physical sunscreen and she thought that it might be causing me sensitivity that is leading to my melasma. I have searched all over and kind find anything confirming what she said. I’m confused??

Andrea, maybe she got it confused with oxybenzone or octocrylene? These are chemical UV filters that can cause irritations. Octyldodecanol can cause irritations, but it’s very, very rare.
