Diocytldodecyl Stearoyl Glutamate
INCI: DIOCTYLDODECYL STEAROYL GLUTAMATE
A gentle, amino-acid-based emollient that helps soften and condition skin without clogging pores or causing irritation.
In plain English
This ingredient is a type of oil-like substance made from a fatty alcohol (diocytldodecyl) and a modified amino acid (stearoyl glutamate). It spreads easily on the skin, leaving it feeling smooth and soft without a greasy residue. Think of it as a lightweight moisturizer that helps your skin's barrier stay healthy and comfortable.

Quick decision guide

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 Diocytldodecyl Stearoyl 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
A semi-synthetic emollient created by combining a long-chain fatty alcohol with a derivative of glutamic acid (an amino acid naturally found in skin). It is designed to mimic the skin's own lipids, making it compatible and gentle.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smoother texture. It also helps reduce water loss by reinforcing the skin's natural barrier, keeping moisture locked in.
Pros
Gentle on sensitive skin
Derived from amino acids, it is unlikely to cause stinging or redness, making it suitable for those with eczema or rosacea.
Non-comedogenic
Unlike some heavy oils, this ingredient has a low comedogenic rating, meaning it won't easily clog pores or cause breakouts.
Cons and cautions
May feel heavy for oily skin
In high concentrations, it can leave a slightly rich feel that might not be ideal for very oily skin types.
Less common in drugstore products
It is more often found in mid-to-high-end formulations, so it may be harder to find in budget-friendly options.
Best for
- People with dry or dehydrated skin looking for a gentle moisturizer
- Those with sensitive or reactive skin who want a low-irritation emollient
Use caution if
- Individuals with very oily or acne-prone skin who prefer completely oil-free products
