Ingredient review
Dimethyl Brassylate
INCI: Dimethyl Brassylate
A gentle, plant-derived emollient that softens skin without clogging pores, ideal for sensitive and oily skin types.
In plain English
Dimethyl Brassylate is a lightweight, plant-derived oil-like ingredient that helps keep skin soft and smooth. It works by forming a thin, breathable film on the skin's surface that locks in moisture without feeling greasy or heavy. Because it's non-comedogenic (won't clog pores) and low-irritation, it's a popular choice for sensitive, acne-prone, or oily skin.

Dimethyl Brassylate 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 Dimethyl Brassylate.
- 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
Dimethyl Brassylate is a diester derived from brassylic acid, a naturally occurring dicarboxylic acid found in plants like rapeseed and mustard. It is produced through a sustainable process and is used as a lightweight emollient and skin-conditioning agent in cosmetics.
How it works
When applied to the skin, Dimethyl Brassylate spreads easily and forms a thin, non-occlusive film that reduces water loss (transepidermal water loss, or TEWL) while allowing the skin to breathe. It also helps other ingredients penetrate more effectively and leaves a silky, non-greasy feel.
Pros
Lightweight feel
Unlike heavier oils, Dimethyl Brassylate absorbs quickly and leaves no greasy residue, making it ideal for daytime use and for oily skin types.
Non-comedogenic
It has a low comedogenic rating, meaning it is unlikely to clog pores, which is a major plus for acne-prone individuals.
Cons and cautions
Limited research
Compared to more established emollients like squalane or jojoba oil, there is less published research on Dimethyl Brassylate's long-term skin benefits.
Rare irritation potential
While generally very gentle, a small number of people with extremely sensitive skin may experience mild redness or stinging.
Best for
- People with oily or combination skin who want lightweight moisture
- Those with sensitive skin looking for a gentle emollient
- Anyone seeking a non-comedogenic moisturizer
Use caution if
- Individuals with a known allergy to brassica-derived ingredients (very rare)
Usage tips
Safety summary
Dimethyl Brassylate is considered safe for cosmetic use with a low irritation and sensitization potential. It is non-comedogenic and well-tolerated by most skin types, including sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Research on Dimethyl Brassylate is limited but consistent with its use as a safe, effective emollient. Studies focus on its skin-conditioning properties and low irritation profile. More long-term studies would strengthen the evidence base.
Common label clues
