Score terms in plain English

Irritation risk

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Dipotassium Capryloyl Glutamate is a surfactant (cleansing agent) created by combining caprylic acid from coconut oil with glutamic acid, an amino acid. It is often used in sulfate-free cleansers for its mildness.

How it works

It works by attracting both water and oil, allowing it to lift away dirt, sebum, and impurities from the skin's surface. Unlike harsher sulfates, it has a larger molecular structure that is less likely to penetrate and irritate the skin barrier.

Pros

Ultra-gentle cleansing

Removes impurities without disrupting the skin barrier, making it ideal for daily use on sensitive or compromised skin.

pH-friendly

Works well at skin's natural pH (around 5.5), helping to avoid irritation and maintain a healthy acid mantle.

Cons and cautions

Lower foam volume

Produces a creamy, low lather that may not satisfy users who associate heavy foam with effective cleansing.

Higher cost

As a specialty amino-acid surfactant, it is more expensive than common sulfates, which can raise product prices.

Best for

  • People with dry, sensitive, or eczema-prone skin
  • Anyone looking for a sulfate-free, gentle cleanser

Use caution if

  • Those who prefer high-foaming cleansers may find it too mild

Usage tips

Use in a sulfate-free cleanser for a non-stripping wash.
Pair with hydrating ingredients like glycerin or aloe for extra comfort.

Safety summary

Considered very safe for topical use. Low irritation and sensitization potential. No known toxicity concerns at typical cosmetic concentrations.

Research notes

Amino-acid surfactants like this one are well-documented in cosmetic science as mild alternatives to sulfates. Studies show they cause less protein denaturation and barrier disruption than sodium lauryl sulfate.

Common label clues

Typical concentration
1–15% in rinse-off products; lower in leave-on formulas
Regulatory status
Approved for cosmetic use globally; no known restrictions in the EU, US, or Japan.
Common uses
Facial cleansers, Body washes, Shampoos, Micellar waters
Environmental note
Derived from renewable plant sources (coconut oil) and is readily biodegradable, making it a more eco-conscious choice than some petroleum-based surfactants.

Good to know

  • Often listed near the middle or end of an ingredient list because effective concentrations are low.
  • Compatible with other mild surfactants to adjust foam and feel.
