What Is Ethylhexyl Myristate?
Ethylhexyl Myristate is a clear lightweight liquid made by joining myristic acid, a fatty acid usually taken from coconut or palm kernel oil, with 2-ethylhexanol, an alcohol used in many cosmetic ingredients. The result is an ester that feels silky and non greasy on skin. Cosmetic chemists started using it in the 1970s when they were looking for plant-based options that could soften skin without the heavy feel of mineral oil. Today the ingredient is produced in large batches through a simple reaction that combines purified myristic acid with 2-ethylhexanol under heat and a catalyst, then filters away any leftovers to leave a high-purity product.
Because it spreads easily and leaves a velvety finish, Ethylhexyl Myristate shows up in a wide range of products such as facial and body moisturizers, sunscreens, makeup primers, liquid foundations, lipsticks, hair serums, sheet masks, anti-aging creams and aftershaves. It is also used to thin thicker butters or waxes, helping formulas stay smooth and easy to apply.
Ethylhexyl Myristate’s Cosmetic Benefits/Uses
In skin and hair care formulas Ethylhexyl Myristate serves one main purpose as an emollient. It fills the tiny gaps between dead skin cells so the surface feels softer and looks smoother. This cushioning effect reduces dryness, helps makeup glide on evenly and can minimize the whitish cast of mineral sunscreens. As an emollient it can also cut down on stickiness in heavier creams, making them feel lighter while still locking in moisture.
Who Can Use Ethylhexyl Myristate
Ethylhexyl Myristate suits most skin types including normal, dry and combination because it is light and fast absorbing. Oily or acne prone skin may prefer it in lower amounts since heavy use of any fatty ester can add extra shine.
The ingredient is made from plant sourced myristic acid and a lab made alcohol so it is generally seen as vegan and vegetarian friendly. No animal materials are used in its typical production.
Available safety data shows no known issues for pregnant or breastfeeding women when the ingredient is used in regular cosmetic levels. This is not medical advice and anyone expecting or nursing should check with a doctor before adding new products just to be safe.
Ethylhexyl Myristate does not increase photosensitivity and can even help sunscreen filters spread more evenly. No extra sun care steps are needed beyond normal daily protection.
Potential Side Effects/Adverse Reactions
Responses to topical Ethylhexyl Myristate differ from person to person. The points below cover potential side effects though most users will not experience them when the ingredient is used correctly in finished products.
- Mild redness or stinging in very sensitive skin
- Contact dermatitis in rare cases of true allergy to fatty esters
- Breakouts or clogged pores if high amounts are applied to acne prone areas
- Eye irritation if the product gets into the eyes
If any of these effects occur stop using the product and consult a healthcare professional.
Comedogenic Rating
Rating: 2 out of 5. Ethylhexyl Myristate has a medium length fatty chain that can sit in pores if used at high levels, yet its light texture lets most formulas absorb quickly without leaving a thick film. In typical concentrations found in lotions and makeup it poses only a mild clogging risk. People who break out easily may still prefer to use it sparingly or choose products where it appears lower on the ingredient list. Climate matters too; in humid weather the skin produces more oil so the chance of congestion rises slightly.
Summary
Ethylhexyl Myristate is mainly an emollient, smoothing rough skin by filling in microscopic gaps so the surface feels soft and looks even. Its silky slip also helps spread pigments and sunscreen filters, which is why it shows up in foundations, primers and SPF products. The ingredient has stayed popular since the 1970s because it offers the cushion of heavier oils without the greasy afterfeel that consumers dislike.
Safety data places it among low concern ingredients for topical use with allergies and major irritations reported rarely. As with any new cosmetic it is smart to patch test on a small area first to make sure your skin gets along with the formula.
