Ingredient review
Glycereth-3 Caprylate/Caprate
INCI: GLYCERETH-3 CAPRYLATE/CAPRATE
A gentle, non-greasy emollient that improves product feel and skin softness without clogging pores.
In plain English
Glycereth-3 Caprylate/Caprate is a semi-synthetic ingredient made from glycerin (a natural humectant) and fatty acids from coconut or palm oil. It acts as an emollient, meaning it helps soften and smooth the skin by filling in the tiny gaps between skin cells. Unlike heavy oils, it feels light and non-greasy, so it's great for lotions, creams, and cleansers. It also helps other ingredients spread evenly and can improve the texture of a product.

Quick decision guide
Easy yes for most routines
Glycereth-3 Caprylate/Caprate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Glycereth-3 Caprylate/Caprate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 glycerin with caprylic and capric fatty acids (derived from coconut or palm oil). It belongs to the glycereth family, which are ethoxylated glycerin derivatives known for being mild and water-soluble.
How it works
It sits on the skin's surface, forming a thin, breathable film that reduces water loss and makes the skin feel smooth. Its molecular structure allows it to mix well with both water and oil phases in a formula, helping to stabilize emulsions and improve the spreadability of creams and serums.
Pros
Lightweight feel
Unlike heavy oils, this ingredient absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and gel-based products.
Low irritation potential
It is considered very mild and non-irritating, even for sensitive skin, and has a low comedogenic rating, so it won't clog pores.
Cons and cautions
Sustainability concerns
The fatty acids are often sourced from palm oil, which can be linked to deforestation unless certified sustainable. Look for RSPO-certified sources if this matters to you.
Semi-synthetic processing
The ethoxylation step involves synthetic chemistry, which may not appeal to those seeking 100% natural or minimal processing in their skincare.
Best for
- People with normal to oily skin looking for a light moisturizer
- Anyone who prefers non-greasy, fast-absorbing skincare
- Those with sensitive or acne-prone skin
Use caution if
- Individuals with a known allergy to coconut or palm oil derivatives
- Those seeking exclusively natural, non-ethoxylated ingredients
Usage tips
Safety summary
Glycereth-3 Caprylate/Caprate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and no significant toxicity concerns have been identified in available safety assessments.
Research notes
Safety data is primarily based on analog studies of similar glycereth esters and fatty acid derivatives. The Cosmetic Ingredient Review (CIR) panel has reviewed related ingredients and found them safe as used. Direct peer-reviewed studies on this specific compound are limited, but its chemical class is well-understood.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU Cosmetics Regulation and the US FDA (as a cosmetic ingredient). No concentration restrictions are typically imposed.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens, Makeup
- Environmental note
- Derived from plant-based fatty acids, but the ethoxylation process is energy-intensive. Sustainable sourcing of palm oil is a key environmental consideration.
Good to know
- This ingredient is often used as a replacement for mineral oil or silicones in 'natural' formulations.
- It can also function as a mild solubilizer for fragrances or essential oils.
