INCI: POLYGLYCERYL-3 METHYLGLUCOSE DISTEARATE
A mild, effective emulsifier that creates rich, stable creams without common irritation, ideal for sensitive skin.
In plain English
This ingredient is a helper that allows water and oil to mix together in your skincare products, creating a smooth, creamy texture that doesn't separate. It's made from natural sources like glycerin and glucose, so it's very gentle on the skin and unlikely to cause breakouts or irritation.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic emulsifier derived from glycerin, glucose (from corn or other plants), and stearic acid (from vegetable oils). It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers.
How it works
It has both water-loving and oil-loving parts, so it positions itself at the boundary between water and oil droplets. This stabilizes the mixture, preventing separation and giving the product a uniform, luxurious feel. It also helps other ingredients spread evenly on the skin.
Pros
Gentle on skin
Unlike some emulsifiers that can strip or irritate, this one is very mild and helps maintain the skin's natural barrier.
Non-comedogenic
It won't clog pores, making it a safe choice for acne-prone or oily skin types.
Cons and cautions
Not for water-free products
It requires water to function as an emulsifier, so it's not used in anhydrous balms or oils.
Formula-dependent performance
Its emulsifying power can be affected by other ingredients, so formulators need to balance the recipe carefully.
Best for
- Anyone with sensitive, dry, or normal skin looking for a gentle moisturizer
- People who prefer products with mild, plant-derived emulsifiers
Use caution if
- Those with a known allergy to any of its source ingredients (rare)
