All You Need to Know About Myristyl Myristate

The Myristyl Myristate or Myristate of myristyl is obtained through the reaction of myristic acid and myristyl alcohol (a saturated fatty alcohol).

Also known as tetradecanoic acid, myristic acid is naturally present in fats and oils (both vegetable and animal), particularly in:

  • Coconut oil;

  • The nutmeg oil;

  • Palm oil.

The salts of this active ingredient are obtained by reacting with basic substances such as potassium hydroxide or sodium hydroxide. For instance, butyl myristate is the result of the reaction between myristic acid and butyl alcohol. As for isopropyl myristate, it is derived from myristic acid and isopropyl alcohol. Myristyl Myristate has emollient and moisturizing properties. This is due to the combination of fats and oils with alcohol.

Myristyl Myristate: What is its purpose?

Myristyl Myristate is an agent:

  • Opacifier: it reduces the transparency or translucency of skincare treatments;

  • Emollient: Myristyl Myristate serves as an emollient in certain skincare products such as lotions, creams, and hair care treatments. It softens and smooths the skin. Once applied, it forms a protective barrier on the skin, shielding it from damage caused by external factors (microbes and protection).

  • On skin care: it enhances the quality of the skin and promotes its hydration.

Furthermore, this ingredient enhances the texture of skincare products. Spreading across the skin's surface, it provides a sensation of softness. It also reduces the watery feel of lotions and creams and strengthens the spreadability of the products. Thanks to its emulsifying properties, it prevents the separation of water and oil-based components of the skincare product.

Furthermore, in addition to being suitable for a wide range of pH values, Myristyl Myristate can be combined with anionic, cationic, and non-ionic surfactants.

Myristyl Myristate: In which skincare products is it found?

Myristyl Myristate is used in a variety of skincare products. In addition to enhancing the texture of formulations, it helps to retain their moisture content.

It is present in:

  • Lip pencils;

  • Eyebrow pencils;

  • Facial creams;

  • The soaps;

  • The lotions;

  • Shaving creams;

  • Conditioners;

  • Moisturizing treatments for the face and body;

  • Lip balms.
