What it is
A synthetic ester created by combining myreth-3 (a polyethylene glycol ether of myristyl alcohol) with ethylhexanoic acid. It functions as an emollient and skin conditioning agent.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft feel. It also helps other ingredients spread evenly and can reduce the whitish residue some sunscreens leave behind.
Pros
Lightweight feel
Unlike heavy oils, this ester absorbs quickly and leaves a velvety finish, making it ideal for daytime moisturizers and makeup.
Improves sunscreen texture
It helps reduce the chalky white cast often seen in mineral sunscreens, making them more cosmetically elegant.
Cons and cautions
Synthetic origin
As a lab-created ingredient, it may not appeal to those seeking natural or plant-based formulations.
Limited long-term data
While generally considered safe, there is less independent research on this specific ester compared to more common emollients.
Best for
- People who prefer lightweight, non-greasy moisturizers
- Those with oily or combination skin looking for a silky finish
Use caution if
- Individuals with known sensitivity to synthetic esters (rare)
