Myristic Acid

TL;DR. This ingredient is used mainly as a fatty structurant and soap precursor, helping cleansing bars, shaving products, and cream cleansers build body, opacity, and dense foam when neutralized.

What does Myristic Acid do in a cosmetic formula?

This ingredient is used mainly as a fatty structurant and soap precursor, helping cleansing bars, shaving products, and cream cleansers build body, opacity, and dense foam when neutralized.

Is Myristic Acid clean?

It has a straightforward clean-beauty profile, with low systemic concern and no major restricted-list issue in typical cosmetic use. In alkaline cleansing systems or at higher levels, it can feel drying or be less comfortable for very reactive or blemish-prone skin.

Is Myristic Acid sustainable?

This material is commonly sourced from coconut or palm-kernel-derived fats, and it is readily biodegradable. The main sustainability question is feedstock traceability, especially where palm-derived supply chains are involved.

Is Myristic Acid COSMOS-approved?

It is generally permitted under COSMOS-natural and COSMOS-organic when made from allowed natural feedstocks and approved processing routes. It fits Green Chemistry principles reasonably well because it can come from renewable oils, uses simple fat-splitting or purification chemistry, and biodegrades readily.

How does Myristic Acid work chemically?

The molecule is a straight-chain, 14-carbon saturated carboxylic acid with a waxy solid profile, a melting point around 54°C, and low water solubility until neutralized. It is oxidation-stable compared with unsaturated lipids, and typical use can range from low single-digit percentages as a structuring aid to higher levels in soap-based cleansing or shaving systems.
