Ingredient review
Methyl Laurate/Myristate
INCI: METHYL LAURATE/MYRISTATE
A lightweight emollient that softens skin without feeling greasy, generally well-tolerated and non-irritating.
In plain English
Methyl Laurate/Myristate is a blend of two fatty acid esters (methyl laurate and methyl myristate) that act as emollients. In plain terms, they help soften and smooth the skin by forming a light, non-greasy film that reduces water loss and improves texture. These ingredients are derived from natural fats (like coconut or palm oil) through a chemical process, making them semi-synthetic. They are commonly found in moisturizers, cleansers, and makeup removers because they spread easily and leave a silky feel without clogging pores.

Quick decision guide
Useful, but context matters
Methyl Laurate/Myristate 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 Methyl Laurate/Myristate.
- 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 mixture of methyl esters of lauric acid and myristic acid, which are fatty acids naturally found in coconut oil and palm kernel oil. The esters are created by reacting the fatty acids with methanol, resulting in a lightweight, oily liquid that is clear and odorless.
How it works
When applied to the skin, methyl laurate/myristate sits on the surface and fills the gaps between skin cells, creating a smooth, soft feel. It also helps to reduce transepidermal water loss (the water that evaporates from your skin) by forming a protective barrier, which keeps the skin hydrated. Because it is non-greasy, it is often used in formulations that need a light, silky texture.
Pros
Lightweight feel
Unlike heavier oils, methyl laurate/myristate absorbs quickly and leaves no sticky residue, making it ideal for daytime use or under makeup.
Low irritation potential
It is considered very safe for most skin types, including sensitive skin, with minimal risk of redness or stinging.
Cons and cautions
Semi-synthetic origin
While derived from natural fats, the esterification process makes it a semi-synthetic ingredient, which may not align with 'all-natural' skincare preferences.
Sustainability concerns
Palm and coconut oil sourcing can be linked to deforestation and habitat loss unless certified sustainable.
Best for
- People with normal to oily skin looking for a light moisturizer
- Those who prefer non-greasy, fast-absorbing skincare products
Use caution if
- Individuals with a known allergy to coconut or palm derivatives (rare)
Usage tips
Safety summary
Methyl laurate/myristate is considered safe for topical use in cosmetics. It has low irritation and sensitization potential, and is not known to be toxic or carcinogenic. However, as with any ingredient, patch testing is recommended for those with very sensitive skin or known allergies.
Research notes
Research on methyl laurate and myristate is limited but consistent with their use as safe emollients. The Cosmetic Ingredient Review (CIR) panel has reviewed both esters and concluded they are safe in current cosmetic concentrations. No significant adverse effects have been reported in human or animal studies.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed methyl laurate and methyl myristate safe as used in cosmetics.
- Common uses
- Moisturizers, Cleansers, Body lotions, Makeup removers
- Environmental note
- Sourcing of palm and coconut oil can impact rainforests and biodiversity. Look for products with RSPO-certified palm oil or sustainably sourced coconut oil to reduce environmental footprint.
Good to know
- Methyl laurate/myristate is often used as a replacement for silicone oils in 'silicone-free' formulations.
- It is considered non-comedogenic, meaning it is unlikely to clog pores.
