What Myristic Acid does

Adds body and a creamy texture
Forms soap-like salts for foaming cleansers
Helps give creams a firm structure

Myristic Acid is a saturated fatty acid, a type of fat-derived molecule with a straight chain. It comes mainly from plant oils such as coconut oil and palm kernel oil, and it is also found in some animal fats.

Formulators use it for a few reasons. When it is mixed with a base like potassium hydroxide, it turns into a soap, which helps cleansers foam and rinse clean. In creams and lotions, it adds body and a soft, slightly waxy structure. On skin, it feels smooth and cushiony and blends in easily.

Good for

Suits people who like rich, creamy textures and foamy cleansers, and it often appears in moisturizers, sunscreens and body lotions.

Be careful if

Nothing in particular for most skin types.

Frequently asked questions

Is Myristic Acid good for sensitive skin?

It is generally well tolerated and common in everyday formulas. Everyone reacts differently, so patch testing a new product on a small area is a sensible first step. If you sting easily, look at the full ingredient list, not just one ingredient.

Is Myristic Acid the same as myristate?

They are closely related. Myristic Acid is the fatty acid itself, while myristate salts form when it is combined with a base such as potassium or sodium. Labels may list either form, and the salts are the ones that help cleansers foam.
