Ingredient review
Glycereth-7 Caprylate/Caprate
INCI: GLYCERETH-7 CAPRYLATE/CAPRATE
A gentle, water-friendly emollient that softens skin without a greasy feel, ideal for lightweight formulas.
In plain English
Glycereth-7 Caprylate/Caprate is a semi-synthetic ingredient made by attaching fatty acids (from coconut or palm oil) to a glycerin chain. It acts as a skin softener that mixes easily with water, so it can be used in lightweight lotions, gels, and cleansers without leaving a heavy or sticky residue. Think of it as a moisturizing helper that spreads nicely and helps other ingredients absorb better.

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 water-soluble ester of glycereth-7 (a glycerin derivative) and caprylic/capric fatty acids. It is produced through a controlled chemical reaction that combines natural fatty acids with a modified glycerin backbone, resulting in a clear, mild liquid that functions as both an emollient and a skin-conditioning agent.
How it works
When applied to the skin, Glycereth-7 Caprylate/Caprate forms a thin, breathable film that helps reduce water loss (transepidermal water loss, or TEWL) while keeping the skin feeling smooth and soft. Because it is water-soluble, it rinses off easily and does not clog pores. It also helps other ingredients spread more evenly across the skin, improving the texture and feel of the product.
Pros
Lightweight hydration
It softens skin without leaving a greasy or sticky feel, making it ideal for daytime use or under makeup.
Gentle on skin
With low irritation and comedogenic risk, it is suitable for sensitive and acne-prone skin types.
Cons and cautions
Sustainability concerns
The fatty acids may come from palm oil, which can be linked to deforestation unless sourced responsibly.
Limited research
Compared to classic emollients like glycerin or jojoba oil, there is less published data on its long-term skin benefits.
Best for
- People with oily or combination skin who want hydration without heaviness
- Those who prefer water-based, lightweight skincare products
Use caution if
- Individuals with known allergies to coconut or palm oil derivatives (rare)
