What it is
A semi-synthetic ester created by reacting shea butter fatty acids with polyglycerin-3. It functions primarily as an emulsifier and mild skin conditioner.
How it works
It reduces surface tension between oil and water phases, allowing them to form a stable, uniform mixture. On the skin, it leaves a thin, non-sticky film that helps retain moisture and improves texture.
Pros
Gentle on skin
Derived from shea butter and polyglycerin, it has a very low irritation potential and is well-tolerated even by sensitive skin types.
Eco-friendly profile
Made from renewable plant sources and biodegradable, making it a more sustainable choice compared to some synthetic emulsifiers.
Cons and cautions
Limited water-thin use
It works best in creams and lotions; for very thin, watery serums, other emulsifiers may be more effective.
Higher cost
Because it is a specialty ingredient, it can be more expensive than common emulsifiers like cetearyl alcohol.
Best for
- Anyone looking for a gentle, plant-based emulsifier
- People with sensitive or reactive skin
- Formulators creating natural-leaning products
Use caution if
- Those with a known allergy to shea butter (rare)
