Polyglyceryl-6 Shea Butterate
INCI: POLYGLYCERYL-6 SCLEROCARYA BIRREA SEEDATE
A mild, eco-friendly emulsifier that helps blend water and oil in creams and lotions while leaving skin feeling soft.
In plain English
This ingredient is a modified form of shea butter that has been combined with polyglycerin to create a gentle emulsifier. Emulsifiers are the workhorses that allow water and oil to mix into a stable cream or lotion. Because it's derived from shea butter, it also provides some skin-conditioning benefits, helping to soften and smooth the skin without feeling greasy.

What it is
Polyglyceryl-6 Sclerocarya Birrea Seedate is a semi-synthetic ester created by reacting polyglycerin-6 with fatty acids from shea butter (Sclerocarya birrea seed oil). It functions primarily as a non-ionic emulsifier, meaning it helps stabilize water-in-oil or oil-in-water emulsions without relying on harsh surfactants.
How it works
In a cosmetic formula, this ingredient sits at the interface between water and oil droplets, reducing surface tension so they can mix evenly. This creates a smooth, uniform texture in creams and lotions. Additionally, its shea butter origin gives it mild emollient properties, so it can help soften the skin's surface and reduce moisture loss.
Pros
Gentle on skin
Unlike some traditional emulsifiers, this ingredient has a very low irritation risk, making it suitable for sensitive skin and daily-use products.
Plant-derived and eco-friendly
Sourced from shea butter, a renewable resource, and produced with a relatively low environmental footprint compared to petroleum-based emulsifiers.
Cons and cautions
Limited stability in extreme pH
In very acidic or alkaline formulas, its emulsifying performance may decline, requiring additional stabilizers or co-emulsifiers.
Higher cost than conventional emulsifiers
Because it's a specialty ingredient, products containing it may be more expensive than those using standard emulsifiers like cetearyl alcohol.
Best for
- People with sensitive or dry skin looking for gentle moisturizers
- Anyone who prefers plant-derived ingredients in their skincare
Use caution if
- Those with a known allergy to shea butter or polyglycerins (rare)
