Ingredient review
Dimer Dilinoleyl Bis-Lauroyl Sarcosinate/Myristoyl Methyl Beta-Alaninate
INCI: DIMER DILINOLEYL BIS-LAUROYL SARCOSINATE/MYRISTOYL METHYL BETA-ALANINATE
A lightweight, non-greasy emollient that helps soften skin and improve product feel without clogging pores.
In plain English
This ingredient is a synthetic oil-like compound made from fatty acids and amino acids. It spreads easily on the skin, leaving a silky, non-sticky feel. It helps moisturize by forming a thin, breathable film that reduces water loss, but it is not a humectant (it doesn't pull water into the skin). Think of it as a modern, lightweight alternative to heavier oils or silicones.

Quick decision guide
Useful, but context matters
Dimer Dilinoleyl Bis-Lauroyl Sarcosinate/Myristoyl Methyl Beta-Alaninate 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 Dimer Dilinoleyl Bis-Lauroyl Sarcosinate/Myristoyl Methyl Beta-Alaninate.
- 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 synthetic ester formed by combining dimer dilinoleic acid (a fatty acid from plant oils) with lauroyl sarcosinate and myristoyl methyl beta-alaninate (amino-acid derivatives). It is designed to be a gentle, non-comedogenic emollient.
How it works
It sits on the skin's surface, filling in gaps between skin cells to smooth texture and reduce water loss (transepidermal water loss, or TEWL). Its molecular structure allows it to spread thinly without feeling heavy or greasy, improving the sensory feel of a product.
Pros
Lightweight feel
Unlike heavier oils, this ingredient leaves a silky, non-greasy finish that works well under makeup or sunscreen.
Low pore-clogging risk
Its molecular structure makes it unlikely to block pores, making it a good choice for acne-prone or oily skin.
Cons and cautions
Not a humectant
It only helps seal in moisture; it does not attract water to the skin, so it works best paired with hydrating ingredients like glycerin.
Synthetic origin
It is lab-made, which may be a turn-off for consumers seeking 100% natural or plant-derived ingredients.
Best for
- People with oily or combination skin who want moisture without shine
- Anyone looking for a silicone-free, lightweight emollient
Use caution if
- Those seeking a deeply occlusive moisturizer for very dry skin (this is lighter than petrolatum or shea butter)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic potential. No known significant safety concerns based on available data.
Research notes
Limited peer-reviewed studies specifically on this ingredient, but its components (dimer dilinoleic acid, amino-acid esters) are well-studied and considered safe. Safety assessments rely on analog data and industry experience.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers, Lip products
- Environmental note
- Synthetic but biodegradable under standard conditions. Its production is less resource-intensive than some plant oils, though it is not typically certified organic.
Good to know
- This ingredient is often used as a silicone alternative because it provides a similar silky feel without the environmental concerns associated with some silicones.
- It is stable and does not easily oxidize, giving products a longer shelf life.
