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

Usage tips

Look for it in moisturizers and serums for a lightweight finish.
Pair with humectants like glycerin for balanced hydration.

Safety summary

PPG-4 Myristyl Ether is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, as with any ingredient, patch testing is recommended for those with very sensitive skin.
