Why has Myristyl, such an inconspicuous ingredient, become indispensable?
In cosmetic formulations, certain ingredients go unnoticed, but they ensure the stability, texture, and overall effectiveness of a product. The Myristyl Myristate is one of them. Often overlooked by the general public, it nevertheless plays a central role in the formulation of many creams, balms, and lotions. What are its effects? Is it safe for all skin types?
What is Myristyl Myristate?
Myristyl Myristate is an ester of two fatty acids:’myristic acid (a saturated fatty acid naturally present in coconut oil or nutmeg) and’myristyl alcohol (a fatty alcohol). The result is a waxy substance used for its texturing, emollient, and stabilizing properties.
It is classified as a non-irritating fatty alcohol and is notable for its good skin compatibility, although it should be avoided in cases of highly sensitive skin.
Technical functions of Myristyl Myristate
1. Texture improvement
This ingredient helps create richer, creamier formulas that are easy to spread. It gives creams and lotions consistency. It reduces the feeling of moisture on the skin, leaving it feeling softer and more even.
2. Emollient role
Myristyl Myristate forms a lipid film on the skin's surface. It softens and protects the epidermis, while limiting water loss.
3. Stabilization of emulsions
Its role as a co-emulsifier is crucial in maintaining cohesion between the aqueous and oily phases of a cosmetic product, preventing phase separation (separation of components).
4. Wide compatibility
Myristyl Myristate adapts to a wide range of pH levels and is compatible with many surfactants. It acts as a mild surfactant, particularly in cleansers.
Where is it found in cosmetics?
Myristyl Myristate is found in a wide variety of products, including:
- Face and body creams
- Lip balms
- Hair care products (conditioners, leave-in treatments)
- Body lotions
- Soaps and cleaning products
- Make-up products (pencils, foundations)
- Shaving creams
The concentrations used vary depending on the product, generally between 1 % and 10 %.
Tolerance and precautions
Visit Myristyl Myristate is generally well tolerated, even by sensitive skin. However, in people prone to skin reactions or allergies, it may cause increased sensitivity when used in high concentrations. If in doubt, it is recommended to test the product on a small area of skin beforehand.
