Glycereth-26 Caprylate
INCI: GLYCERETH-26 CAPRYLATE
A gentle, water-loving emollient that softens skin and helps other ingredients spread evenly without clogging pores.
In plain English
Glycereth-26 Caprylate is a mild ingredient made from glycerin (a natural moisturizer) and caprylic acid (a fatty acid from coconut or palm oil). It helps products feel smooth and silky on your skin, while also helping other ingredients mix well with water. Think of it as a helper that makes your cleanser or moisturizer feel nicer and spread more easily, without leaving a greasy residue.

Quick decision guide
Useful, but context matters
Glycereth-26 Caprylate 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-26 Caprylate.
- 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 compound created by reacting glycerin with ethylene oxide and caprylic acid. It belongs to the family of ethoxylated glycerides, which are known for being water-soluble and gentle on skin.
How it works
It works as both an emollient (softening the skin's surface) and a surfactant (helping oil and water mix). In a product, it reduces surface tension so that other ingredients spread evenly, and it leaves a light, non-greasy film that helps lock in moisture.
Pros
Gentle on skin
Rated very low on irritation scales, making it suitable for sensitive skin and daily use in cleansers and moisturizers.
Improves product feel
Creates a silky, smooth texture that helps serums and lotions glide on without stickiness, enhancing the user experience.
Cons and cautions
Sustainability concerns
Caprylic acid is often sourced from palm or coconut oil, which can involve environmental issues like deforestation if not certified sustainable.
Ethoxylation byproducts
The manufacturing process can create trace amounts of 1,4-dioxane, a potential contaminant, though reputable brands purify to safe levels.
Best for
- People with normal to dry skin looking for light hydration
- Those who prefer non-greasy, water-soluble emollients
- Sensitive skin types seeking gentle ingredients
Use caution if
- Individuals with known allergies to ethoxylated compounds (rare)
- Strict vegans may want to verify source (often plant-based but can be synthetic)
Usage tips
Safety summary
Glycereth-26 Caprylate is considered safe for cosmetic use at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has evaluated similar ethoxylated glycerides and found them safe when formulated to minimize impurities. It has low irritation and comedogenic potential, making it suitable for most skin types.
Research notes
Research on ethoxylated glycerides like Glycereth-26 Caprylate shows they are effective mild surfactants and emollients with good skin compatibility. Studies indicate low acute toxicity and no significant skin sensitization. However, long-term human studies specific to this compound are limited, so evidence is based on broader class safety.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (USA) and EU CosIng database, with no concentration restrictions in leave-on or rinse-off products.
- Common uses
- Cleansers, Toners, Serums, Moisturizers, Shampoos
- Environmental note
- Sourcing of caprylic acid from palm oil can contribute to habitat loss; choose brands that use certified sustainable palm oil or coconut-derived alternatives.
Good to know
- It is often used as a milder alternative to traditional emulsifiers like polysorbates.
- The '26' refers to the number of ethylene oxide units, which determines its water solubility and mildness.
