Ingredient review
Sucrose Mortierellate
INCI: SUCROSE MORTIERELLATE
A gentle, biotech-derived emollient that helps soften and condition skin without clogging pores, ideal for sensitive and dry skin types.
In plain English
Sucrose Mortierellate is a fancy name for a sugar (sucrose) combined with oil from a special microbe called Mortierella alpina. This creates a lightweight, non-greasy ingredient that helps your skin feel smooth and soft. It's like a gentle moisturizer that sits on the surface of your skin to prevent water loss, but it's not heavy or sticky. Because it's made in a lab using fermentation (similar to how yogurt is made), it's considered a sustainable and consistent alternative to plant oils.

Quick decision guide
Useful, but context matters
Sucrose Mortierellate 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 Sucrose Mortierellate.
- 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 biotechnologically produced ester of sucrose and fatty acids from Mortierella alpina oil, used as an emollient and skin conditioner in cosmetic formulations.
How it works
It forms a thin, breathable film on the skin's surface that helps lock in moisture and smooth the skin texture. Its molecular structure allows it to mimic the skin's natural lipids, improving barrier function without feeling heavy.
Pros
Lightweight hydration
Unlike heavy oils or butters, Sucrose Mortierellate provides a silky, non-greasy feel that absorbs quickly, making it comfortable for daytime use under makeup or sunscreen.
Gentle for sensitive skin
Because it's derived from fermentation rather than common plant allergens, it has a very low irritation potential and is often well-tolerated by those with eczema or rosacea.
Cons and cautions
Limited research on long-term effects
While initial studies and safety assessments are positive, there are fewer long-term human trials compared to traditional emollients like shea butter or mineral oil.
Not a heavy-duty occlusive
For extremely dry or compromised skin, this ingredient may not provide enough barrier repair on its own and may need to be paired with richer occlusives like petrolatum.
Best for
- People with dry or dehydrated skin looking for a lightweight moisturizer
- Those with sensitive or reactive skin who want a gentle emollient
Use caution if
- Individuals with known allergies to Mortierella-derived ingredients (rare)
Usage tips
Safety summary
Sucrose Mortierellate is considered safe for topical 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 Sucrose Mortierellate specifically is limited, but studies on similar sucrose esters and Mortierella-derived oils indicate good skin compatibility and moisturizing properties. More human studies would strengthen the evidence base.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated similar sucrose esters and found them safe as used.
- Common uses
- Moisturizers, Anti-aging creams, Serums, Eye creams
- Environmental note
- Produced through fermentation, which generally has a lower environmental footprint than harvesting plant oils, though specific sourcing data for this ingredient is limited.
Good to know
- Sucrose Mortierellate is produced via fermentation, making it a vegan-friendly and sustainable alternative to some plant-derived oils.
- It is often listed near the middle or end of ingredient lists, indicating it's used at moderate concentrations.
