What it is
Ethylhexyl Myristate is an ester created by combining myristic acid (a fatty acid from coconut or palm oil) with ethylhexyl alcohol. It is a clear, lightweight liquid that mimics the feel of natural skin oils.
How it works
It sits on the skin's surface to soften and smooth the outer layer, reducing water loss and improving the slip of the product. It also helps dissolve other ingredients and enhances the spreadability of formulations.
Pros
Lightweight and silky
Gives a smooth, non-greasy feel that makes products pleasant to apply and wear.
Improves product texture
Helps creams and lotions spread evenly, enhancing the overall user experience.

Best for
- People with dry or normal skin looking for a lightweight moisturizer
