Shea Butter Polyglyceryl-6 Esters
INCI: Shea Butter Polyglyceryl-6 Esters
A mild, eco-friendly emulsifier that helps blend oil and water in creams and lotions while leaving skin feeling soft.
In plain English
This ingredient is a modified version of shea butter, made by attaching small chains of glycerin (polyglyceryl-6) to shea butter fatty acids. It acts as a bridge between oil and water, allowing them to mix into a stable, creamy texture. It also helps condition the skin, leaving it smooth without a greasy feel.

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 ester created by reacting shea butter fatty acids with polyglycerin-6. It functions primarily as a non-ionic emulsifier, meaning it doesn't carry an electric charge and is very gentle on the skin.
How it works
In a formula, it positions itself at the interface of oil and water droplets, reducing surface tension so they blend into a uniform emulsion. This creates a stable, creamy product that spreads easily and leaves a soft, non-tacky finish on the skin.
Pros
Gentle on skin
As a non-ionic emulsifier, it has very low irritation potential, making it ideal for sensitive skin formulations.
Improves texture
It creates a smooth, creamy consistency that feels luxurious and non-sticky, enhancing the user experience.
Cons and cautions
Semi-synthetic origin
While derived from shea butter, the polyglyceryl modification is a chemical process, which may not appeal to consumers seeking purely natural ingredients.
Limited to emulsions
It is specifically designed for oil-in-water or water-in-oil emulsions, so it is not useful in anhydrous or single-phase products.
Best for
- Anyone looking for a gentle, plant-based emulsifier in their moisturizer or cleanser
- People with sensitive or reactive skin who want to avoid harsh detergents
Use caution if
- Those seeking a completely unprocessed, natural ingredient (it is semi-synthetic)
Usage tips
Safety summary
Shea Butter Polyglyceryl-6 Esters is considered very safe for topical use. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in cosmetic concentrations.
Research notes
While specific studies on this exact ester are limited, polyglyceryl esters as a class are well-documented as safe, mild emulsifiers. Shea butter itself has known moisturizing and anti-inflammatory properties. The combination is widely used in commercial cosmetics with a strong safety record.
Common label clues
- Typical concentration
- 1-5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as a generally recognized safe ingredient in cosmetics).
- Common uses

- Environmental note
- Derived from shea butter, a renewable resource, and the polyglycerol portion is biodegradable. However, the manufacturing process involves chemical modification.
Good to know
- It is often used as a replacement for PEG-based emulsifiers, which have come under scrutiny for potential impurities.
- Polyglyceryl-6 esters are considered biodegradable and more environmentally friendly than some synthetic alternatives.
