Ingredient review
Glyceryl Dierucate
INCI: Glyceryl Dierucate
A gentle emollient that helps soften and smooth skin without clogging pores, ideal for dry or sensitive skin.
In plain English
Glyceryl dierucate is a synthetic oil-like ingredient that helps soften and smooth the skin. It works by forming a thin, non-greasy film on the skin's surface that locks in moisture and reduces water loss. Because it's derived from erucic acid (a fatty acid found in rapeseed oil), it's very gentle and unlikely to cause irritation or breakouts. You'll find it in moisturizers, lip balms, and hair conditioners where it adds a silky feel without heaviness.

Quick decision guide
Useful, but context matters
Glyceryl Dierucate 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 Glyceryl Dierucate.
- 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
Glyceryl dierucate is a diester of glycerin and erucic acid, a long-chain fatty acid naturally found in rapeseed oil. It is produced synthetically for cosmetics to provide emollient and skin-conditioning benefits.
How it works
When applied to the skin, glyceryl dierucate spreads easily and forms a protective layer that reduces transepidermal water loss (water evaporating from the skin). This helps keep the skin hydrated, soft, and smooth. It also improves the texture of products, making them feel silky and non-sticky.
Pros
Gentle on skin
Glyceryl dierucate has a low irritation and comedogenic risk, making it a safe choice for sensitive or reactive skin types.
Improves product feel
It gives a silky, non-greasy texture to creams and lotions, enhancing the user experience without leaving a heavy residue.
Cons and cautions
Limited research
There is not a large body of peer-reviewed studies specifically on glyceryl dierucate, so long-term safety data is less robust than for more common emollients.
May not suit oily skin
While generally non-comedogenic, in high concentrations it could feel too rich for those with very oily or acne-prone skin.
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 may prefer lighter, non-comedogenic alternatives
Usage tips
Safety summary
Glyceryl dierucate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch testing is recommended for those with known sensitivities.
Research notes
Research on glyceryl dierucate is limited but consistent with its classification as a safe emollient. Studies on similar esters support its low irritation profile. More long-term studies would strengthen the evidence base.
Common label clues
- Typical concentration
- Typically 1-10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions known at typical use levels.
- Common uses
- Moisturizers, Lip products, Hair conditioners
- Environmental note
- Derived from rapeseed oil, which is a renewable resource. However, the synthetic processing may have some environmental impact.
Good to know
- Glyceryl dierucate is often used in combination with other emollients to balance texture.
- It is considered a sustainable ingredient as erucic acid can be sourced from rapeseed oil.
