Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
PPG-4 Myristyl Ether is a synthetic ether derived from myristyl alcohol (a fatty alcohol from coconut or palm oil) and propylene glycol. It is a clear, oily liquid used in cosmetics 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 greasy feel of heavier oils, making products more pleasant to use.
Pros
Lightweight feel
It gives a silky, non-greasy finish that works well for oily or combination skin types.
Low irritation risk
Rated as low-irritation and low-comedogenic, making it suitable for sensitive and acne-prone skin.
Cons and cautions
Synthetic origin
It is lab-made, which may not align with preferences for natural or plant-based skincare.
Limited research
There is less published research on this specific ingredient compared to more common emollients like squalane or jojoba oil.
Best for
- People with normal to oily skin who want lightweight moisture
- Anyone who prefers non-greasy skincare textures
Use caution if
- Those strictly avoiding synthetic ingredients
- Individuals with known sensitivity to propylene glycol derivatives
