Ingredient review
Stearylgluconamide Dilaurate
INCI: Stearylgluconamide Dilaurate
A gentle, sugar-derived emollient that helps moisturize and condition skin with a low risk of irritation or clogged pores.
In plain English
Stearylgluconamide Dilaurate is a semi-synthetic ingredient made by combining a fatty alcohol (stearyl alcohol) with a sugar-derived molecule (gluconamide) and lauric acid. In skincare, it acts as an emollient, meaning it fills in the tiny gaps between skin cells to make the skin feel softer and smoother. It also helps other ingredients spread evenly and can improve the texture of creams and lotions. Because it is derived from sugar and fatty acids, it is generally considered very gentle and unlikely to cause irritation or breakouts.

Quick decision guide
Useful, but context matters
Stearylgluconamide Dilaurate 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 Stearylgluconamide Dilaurate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic compound created by chemically linking stearyl alcohol (a fatty alcohol from plant sources), gluconamide (derived from glucose), and lauric acid (a fatty acid from coconut or palm oil). It belongs to a class of ingredients called alkylgluconamides, which are known for their mildness and compatibility with skin.
How it works
When applied to the skin, Stearylgluconamide Dilaurate forms a thin, non-greasy film that helps reduce water loss from the skin's surface. It also interacts with the skin's natural lipids to improve softness and flexibility. In a product formula, it helps stabilize emulsions (mixtures of oil and water) and gives a pleasant, silky feel without being heavy or sticky.
Pros
Gentle on sensitive skin
Because it is sugar-based, it has a very low irritation potential, making it a good choice for people with easily irritated or reactive skin.
Non-comedogenic
It does not tend to clog pores, so it is suitable for acne-prone skin types that need moisture without breakouts.
Cons and cautions
Limited research
Compared to classic emollients like glycerin or shea butter, there is less independent research on this ingredient's long-term skin benefits.
Potential sustainability issues
The lauric acid and stearyl alcohol may be derived from palm oil, which can be associated with deforestation unless certified sustainable.
Best for
- People with dry or dehydrated skin looking for a gentle, non-irritating moisturizer
- Those with sensitive or reactive skin who want a low-risk emollient
Use caution if
- Individuals with a known allergy to any of its components (very rare)
Usage tips
Safety summary
Stearylgluconamide Dilaurate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Research on this specific ingredient is limited, but it belongs to the well-studied class of alkylgluconamides, which are known for their mildness and skin compatibility. Most evidence comes from manufacturer safety data and general knowledge of similar compounds.
Common label clues
- Typical concentration
- Typically 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the EU, USA, and other major markets. No specific restrictions known at typical use levels.
- Common uses
- Moisturizers, Creams, Lotions, Lip products
- Environmental note
- The sustainability of this ingredient depends on the sourcing of its palm- or coconut-derived components. Look for RSPO-certified palm or sustainably sourced coconut in the supply chain.
Good to know
- Stearylgluconamide Dilaurate is part of a newer generation of sugar-based emollients designed to be milder than traditional fatty alcohols.
- It is often used in 'clean beauty' formulations because it is derived from renewable plant sources.
