Ingredient review
Myristyl Laurate
INCI: Myristyl Laurate
A lightweight, non-greasy emollient that helps soften and smooth skin without clogging pores.
In plain English
Myristyl Laurate is a synthetic ingredient made from myristyl alcohol (a fatty alcohol) and lauric acid (a fatty acid found in coconut oil). In skincare, it works as an emollient, meaning it helps soften and smooth the skin by forming a light, breathable film that reduces water loss. It feels silky and non-greasy, making it popular in moisturizers, creams, and makeup. It is generally considered safe and non-irritating, with a low risk of clogging pores.

Quick decision guide
Useful, but context matters
Myristyl Laurate 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 Myristyl Laurate.
- 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
Myristyl Laurate is an ester—a compound formed by combining myristyl alcohol (a fatty alcohol) and lauric acid (a fatty acid from coconut or palm kernel oil). It is a synthetic ingredient designed to mimic natural skin oils.
How it works
It sits on the skin's surface, creating a thin, protective layer that locks in moisture and prevents water from evaporating (reducing transepidermal water loss, or TEWL). This helps keep skin hydrated, soft, and smooth without a heavy or sticky feel.
Pros
Lightweight feel
Myristyl Laurate absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and makeup.
Low pore-clogging risk
With a low comedogenic rating, it is unlikely to cause breakouts, even for acne-prone skin types.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for those seeking exclusively natural or plant-derived ingredients.
Limited independent research
Most safety data comes from industry-sponsored studies, and there is less public research compared to some natural emollients.
Best for
- People with normal to oily skin looking for a lightweight moisturizer
- Those who prefer non-comedogenic, low-irritation ingredients
Use caution if
- Individuals with known sensitivity to fatty alcohols or esters (rare)
Usage tips
Safety summary
Myristyl Laurate is widely regarded as safe for topical use. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in cosmetic concentrations. The Cosmetic Ingredient Review (CIR) panel has reviewed similar esters and found them safe.
Research notes
Research on Myristyl Laurate specifically is limited, but it belongs to a well-studied class of fatty esters. Studies on similar esters indicate they are safe, non-irritating, and effective emollients. No peer-reviewed human trials were found specifically for this ingredient.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and other major markets. No concentration restrictions are typically imposed.
- Common uses
- Moisturizers, Creams, Lotions, Lip products, Makeup
- Environmental note
- Myristyl Laurate is synthetic and not derived from endangered species. Its environmental impact is considered low, but like all synthetic esters, it is not readily biodegradable in all conditions.
Good to know
- Myristyl Laurate is often used in combination with other emollients to fine-tune texture.
- It is considered safe by major regulatory bodies at typical use levels.
