What Is Polyglyceryl-10 Dimyristate?
Polyglyceryl-10 Dimyristate is a plant-derived ingredient formed by linking ten glycerin units to two molecules of myristic acid, a fatty acid that occurs naturally in coconut oil and nutmeg butter. The result is a mild, biodegradable compound that carries the softness of vegetable oils and the water-friendly character of glycerin. Interest in polyglyceryl esters started in the 1990s as brands looked for gentle alternatives to traditional PEG-based emulsifiers. Advances in green chemistry allowed manufacturers to create this ingredient through a solvent-free process: glycerin is first heated to build the polyglycerin chain, then reacted with myristic acid under vacuum to form the final diester. Today it shows up in an array of rinse-off and leave-on products such as facial cleansers, micellar waters, cream masks, body lotions, lightweight moisturizers and soothing baby care formulas.
Polyglyceryl-10 Dimyristate’s Cosmetic Benefits/Uses
This multitasker supports both the feel and performance of modern skincare.
- Cleansing: Its amphiphilic structure loosens daily grime, makeup and excess oil then lifts them away when the product is rinsed leaving skin fresh but not stripped
- Emulsifying: It binds oil and water into a stable mix which helps creams stay smooth, prevents separation in lotions and lets formulators reduce or eliminate heavier surfactants for a lighter, more skin-friendly texture
Who Can Use Polyglyceryl-10 Dimyristate
Thanks to its mild, oil-in-water balancing nature Polyglyceryl-10 Dimyristate suits nearly every skin type including dry, oily, combination and sensitive. It helps cleanse without stripping so fragile or redness-prone complexions can usually tolerate it, while its lightweight feel will not smother oilier skin. There are no known concerns for mature or acne-prone users although extremely congestion-prone individuals may prefer formulas where it appears at lower percentages.
The ingredient is made from vegetable glycerin and plant-sourced myristic acid so it meets vegan and vegetarian standards with no animal derivatives or testing involved during production.
Current safety data shows no reproductive or developmental risks, so products containing Polyglyceryl-10 Dimyristate are generally considered safe for pregnant or breastfeeding women. Still this is not medical advice and anyone who is expecting or nursing should ask their physician before adding new skincare products just to be sure.
It does not make skin more sensitive to the sun, and it does not interfere with common actives such as retinoids or vitamin C. The ingredient is also biodegradable making it a good choice for users who value eco-conscious formulas.
Potential Side Effects/Adverse Reactions
Responses to topical ingredients differ from person to person. The issues listed below are only potential effects and are unlikely for most users when products are well formulated and used as directed.
- Mild skin irritation, stinging or redness in very sensitive individuals
- Allergic contact dermatitis in people with a specific sensitivity to fatty acid esters
- Temporary eye irritation if the product accidentally gets into the eyes
- Rare clogging of pores when used in exceptionally heavy leave-on formulas on skin already prone to comedones
If you experience any persistent discomfort, discontinue use and consult a healthcare professional.
Comedogenic Rating
Rating: 1/5
Polyglyceryl-10 Dimyristate has a very low tendency to clog pores because its large, water-friendly structure keeps it mostly on the surface and easy to rinse away. It is used at modest levels and often in fluid, oil-in-water formulas which further limit buildup inside pores. Suitable for acne-prone skin in most cases.
Keep in mind that a formula’s entire blend of oils, waxes and silicones influences breakouts more than any single ingredient so overall product design matters.
Summary
Polyglyceryl-10 Dimyristate works as a gentle cleanser and an effective emulsifier. Its glycerin backbone attracts water while the myristic acid tails grip oils so it can break up makeup and dirt then keep oil and water bonded in smooth stable creams.
It is gaining traction among brands that favor plant-based biodegradable materials though it is still less common than classic PEG emulsifiers.
Current data shows it is non irritating non sensitizing and eco friendly, making it a safe bet for most users. As with any new skincare product, do a quick patch test first just to be sure your skin agrees.
