Ingredient review
Polyglyceryl-10 Heptahydroxystearate
INCI: POLYGLYCERYL-10 HEPTAHYDROXYSTEARATE
A gentle, plant-based emulsifier that creates stable, creamy textures without irritating the skin.
In plain English
This ingredient is a helper that allows water and oil to mix together in your skincare products, like lotions and creams. It's made from glycerin (a natural moisturizer) and stearic acid (a fatty acid from plants). Because it's very mild, it's often used in products for sensitive skin, and it helps give a smooth, non-greasy feel.

What it is
Polyglyceryl-10 Heptahydroxystearate is a non-ionic emulsifier derived from glycerin and hydroxystearic acid. It belongs to the polyglyceryl ester family, known for being gentle and biodegradable.
How it works
In a cosmetic formula, it sits at the boundary between oil and water droplets, reducing surface tension so they can mix into a stable emulsion. This prevents the product from separating and gives a creamy, uniform texture. It also helps spread the product evenly on the skin.
Pros
Ultra-gentle on skin
This emulsifier has a very low irritation potential, making it ideal for sensitive skin types and baby products.
Eco-friendly profile
Derived from renewable plant sources and biodegradable, it aligns with sustainable beauty preferences.
Cons and cautions
Limited formula compatibility
It may not perform well in very acidic or high-salt formulations, which can limit its use in certain products.
Higher cost
Compared to conventional emulsifiers, it can be more expensive, which may increase product prices.
Best for
- People with sensitive or reactive skin
- Anyone looking for a gentle, plant-based emulsifier in their skincare
Use caution if
- Those with a known allergy to glycerin or stearic acid derivatives (rare)
