PEG-7 Carapa Guianensis Glyceryl Esters
INCI: PEG-7 CARAPA GUIANENSIS GLYCERYL ESTERS
A gentle, plant-derived emollient that helps skin feel soft and smooth without clogging pores.
In plain English
This ingredient is a modified version of andiroba oil (a natural oil from the Carapa guianensis tree). By attaching PEG-7 (a water-loving chain) to the oil, it becomes easier to mix into water-based products like lotions and creams. It sits on the skin's surface to reduce water loss and leave a silky, non-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 andiroba oil with PEG-7, making the oil more water-dispersible while retaining its emollient properties.
How it works
It forms a thin, breathable film on the skin or hair that helps lock in moisture and smooth rough texture. The PEG part allows it to blend easily into water-based formulas, improving product texture and spreadability.
Pros
Lightweight feel
Unlike pure andiroba oil, this modified version spreads easily and absorbs quickly without leaving a heavy residue.
Low irritation risk
Clinical and anecdotal evidence suggests it is very gentle, making it a good choice for sensitive or reactive skin.
Cons and cautions
Semi-synthetic processing
The PEG modification involves chemical processing, which may not appeal to those seeking entirely natural ingredients.
Potential manufacturing impurities
If not properly purified, PEG compounds can contain trace impurities like ethylene oxide; however, cosmetic-grade ingredients are rigorously tested.
Best for
- People with dry or normal skin looking for a lightweight moisturizer
- Those who prefer plant-derived but effective emollients
Use caution if
- Individuals strictly avoiding all PEG compounds or synthetic processing
