Ingredient review
Cupuacu Butter Polyglyceryl-6 Esters
INCI: THEOBROMA GRANDIFLORUM SEED BUTTER POLYGLYCERYL-6 ESTERS
A gentle, non-greasy emollient derived from cupuacu butter that helps soften and smooth skin without clogging pores.
In plain English
This ingredient is a modified form of cupuacu butter, a fat from the seeds of the cupuacu fruit (related to cacao). By attaching polyglyceryl-6 groups, it becomes more water-friendly and easier to blend into lotions and creams. It sits on the skin's surface to reduce water loss and leaves a silky, non-greasy feel.

Score terms in plain English

moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic ester made by reacting cupuacu seed butter with polyglycerin-6, creating a molecule that combines the emollient properties of the natural butter with improved formulation flexibility.
How it works
It forms a thin, breathable film on the skin that helps lock in moisture and smooth rough texture. Its modified structure allows it to mix easily with both oils and water, so it spreads evenly and doesn't feel heavy or sticky.
Pros
Lightweight feel
Unlike many natural butters, this ester spreads easily and absorbs quickly without leaving a greasy residue, making it ideal for daytime use.
Low clog risk
It has a low comedogenic rating, so it's unlikely to block pores or trigger breakouts, even for acne-prone skin.
Cons and cautions
Less intensive for very dry skin
Because it's lighter than pure cupuacu butter, it may not provide enough moisture for severely dry or cracked skin without a richer occlusive layer.
Not fully natural
The chemical modification means it's not a raw plant ingredient, which might be a drawback for those who prefer entirely natural formulations.
Best for
- People with normal to combination skin who want lightweight moisture
- Anyone looking for a non-comedogenic emollient in lotions or creams
Use caution if
- Those seeking 100% unprocessed natural ingredients
