Ingredient review
Polyglyceryl-4 Laurate/Succinate
INCI: Polyglyceryl-4 Laurate/Succinate
A gentle, biodegradable emulsifier that creates stable, lightweight textures without stripping the skin.
In plain English
Polyglyceryl-4 Laurate/Succinate is a modern emulsifier made from glycerin and fatty acids. Its job is to help water and oil mix together so your lotion or cleanser stays smooth and doesn't separate. Because it's derived from natural sources and is very mild, it's often used in gentle, non-stripping cleansers and lightweight moisturizers that leave skin feeling soft rather than tight or greasy.

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 created by combining polyglycerin (from plant glycerin) with lauric acid (from coconut or palm oil) and succinic acid (a natural organic acid). It belongs to the polyglyceryl ester family, known for being gentle on skin.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. In a cleanser, it helps lift dirt and makeup without stripping the skin's natural moisture barrier. In a moisturizer, it creates a light, even texture that spreads easily and absorbs quickly.
Pros
Ultra-gentle on skin
Unlike some traditional emulsifiers that can be drying or irritating, this ingredient is very mild and helps maintain the skin's natural moisture barrier.
Lightweight texture
It creates emulsions that feel light and silky on the skin, making it ideal for gel-creams, milky cleansers, and fluid lotions.
Cons and cautions
Potential palm oil sourcing
The lauric acid component is often derived from palm oil, which can raise environmental concerns unless certified sustainable.
Limited standalone efficacy
In some formulations, it may need to be paired with other emulsifiers or thickeners to achieve the desired consistency and stability.
Best for
- Anyone with sensitive or easily irritated skin
- People who prefer lightweight, non-greasy moisturizers and cleansers
Use caution if
- Those with a known allergy to any component (rare)
