What Is Lauric/Myristic/Palmitic/Stearic Glycerides?
Lauric/Myristic/Palmitic/Stearic Glycerides is a blend of glycerides derived from four fatty acids that occur naturally in vegetable oils like coconut and palm as well as in animal fats. Chemically it contains mono, di and triglycerides of lauric, myristic, palmitic and stearic acids. This mix looks like a soft wax or thick liquid that melts easily when warmed.
Cosmetic chemists started using these mixed glycerides in the 1970s when they were searching for plant based alternatives to mineral oil. The ingredient found favor thanks to its smooth feel and skin-friendly profile. Today most suppliers make it by gently heating the chosen oils, splitting them with food grade glycerin then purifying the result until the right balance of fatty acids is reached.
You will spot Lauric/Myristic/Palmitic/Stearic Glycerides in many leave-on and rinse-off products. Moisturizers, night creams, hydrating masks, lip balms, solid lotion bars, body butters, creamy cleansers, anti-aging blends and even some cosmetics for sensitive skin use it to boost texture and skin feel.
