Ingredient review
PPG-3 Myreth-11
INCI: PPG-3-MYRETH-11
A synthetic emulsifier that helps cleansers foam and rinse cleanly, but may be drying for sensitive skin.
In plain English
PPG-3 Myreth-11 is a man-made ingredient that helps oil and water mix together in products like face washes and shampoos. It also helps create a nice lather and makes the product rinse off easily. However, because it is a strong cleanser, it can sometimes strip away too much of your skin's natural moisture, especially if you have dry or sensitive skin.

What it is
PPG-3 Myreth-11 is a synthetic surfactant derived from myristyl alcohol and propylene glycol. It belongs to the myreth family of emulsifiers and is commonly used in rinse-off products to improve texture and foaming.
How it works
It works by reducing the surface tension between oil and water, allowing them to mix into a stable emulsion. In cleansers, it helps lift dirt, oil, and makeup from the skin so they can be rinsed away. Its mild foaming action also gives a satisfying sensory experience.
Pros
Effective emulsifier
Helps oil and water mix smoothly, so your cleanser feels consistent and works well every time.
Nice lather
Creates a satisfying foam that makes cleansing feel refreshing and thorough, especially for oily skin types.
Cons and cautions
Can be drying
Because it's a strong surfactant, it may strip natural oils from the skin, leading to tightness or irritation for dry or sensitive skin.
Synthetic origin
It is not naturally derived, which may be a drawback for those who prefer plant-based or minimal-ingredient routines.
Best for
- People with normal to oily skin who enjoy a foamy cleanser
- Anyone using rinse-off products like shampoo or body wash
Use caution if
- Those with very dry, compromised, or eczema-prone skin
- Individuals seeking 100% natural or plant-based ingredients
