Ingredient review
Sodium Caproyl Glutamate
INCI: SODIUM CAPRYLOYL GLUTAMATE
A mild, effective cleanser that respects the skin barrier and is well-tolerated by sensitive skin.
In plain English
Sodium caproyl glutamate is a gentle cleansing ingredient made from coconut oil and the amino acid glutamate. It works by attracting both water and oil, allowing it to lift dirt, makeup, and excess oil from your skin without stripping away its natural moisture. Unlike harsh soaps, it cleanses without leaving your skin feeling tight or dry.

Quick decision guide
Easy yes for most routines
Sodium Caproyl Glutamate 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 Sodium Caproyl Glutamate.
- 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
Sodium caproyl glutamate is a surfactant derived from coconut fatty acids and glutamic acid (an amino acid). It belongs to the family of amino-acid-based cleansers, known for their mildness and compatibility with sensitive skin.
How it works
In a cleanser, sodium caproyl glutamate reduces the surface tension between water and oil, helping to emulsify and rinse away sebum, dirt, and impurities. Its molecular structure is large and gentle, so it doesn't penetrate deeply into the skin or disrupt the lipid barrier, making it less irritating than traditional sulfate surfactants.
Pros
Ultra-gentle on skin
Its large molecular size and amino-acid base make it one of the mildest surfactants, ideal for compromised or sensitive skin.
Supports barrier health
Unlike harsh detergents, it cleanses without stripping essential lipids, helping maintain a healthy moisture barrier.
Cons and cautions
Less effective on heavy makeup
For waterproof or long-wear makeup, you may need a double-cleansing routine or a stronger primary cleanser.
Higher cost
Amino-acid surfactants are generally more expensive to produce, which can raise the price of the final product.
Best for
- People with sensitive, dry, or reactive skin
- Those looking for a sulfate-free, gentle daily cleanser
Use caution if
- Individuals with a known allergy to coconut-derived ingredients (rare)
Usage tips
Safety summary
Sodium caproyl glutamate is considered very safe for topical use. It has a low irritation and comedogenic potential, making it suitable for daily use on all skin types, including sensitive and acne-prone skin.
Research notes
Amino-acid surfactants like sodium caproyl glutamate have been studied for their mildness and skin compatibility. Research indicates they cause less protein denaturation and lipid extraction than traditional anionic surfactants, supporting their use in gentle cleansers.
Common label clues
- Typical concentration
- 5–15% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as a generally recognized safe ingredient in rinse-off products).
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from renewable plant sources (coconut oil and fermented sugar), and is readily biodegradable, reducing aquatic toxicity compared to some conventional surfactants.
Good to know
- Sodium caproyl glutamate is often combined with other mild surfactants to boost foaming and cleansing power.
- It is considered biodegradable and more eco-friendly than many traditional surfactants.
