Ingredient review
Glyceryl Dimyristate
INCI: Glyceryl Dimyristate
A gentle emollient that helps moisturize and soften skin without feeling greasy.
In plain English
Glyceryl dimyristate is an ingredient made from glycerin and myristic acid (a fatty acid found naturally in coconut oil and other fats). In skincare, it works as an emollient, meaning it fills in the tiny gaps between skin cells to make the skin feel smoother and softer. It also helps other ingredients spread more evenly and can improve the texture of creams and lotions. Because it is non-greasy and has a low risk of clogging pores, it is often used in products for normal to oily skin types.

Quick decision guide
Useful, but context matters
Glyceryl Dimyristate 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 Dimyristate.
- 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 diester of glycerin and myristic acid, produced through a controlled chemical reaction. It appears as a waxy solid at room temperature and is used to improve the feel and application of cosmetic products.
How it works
When applied to the skin, glyceryl dimyristate forms a thin, non-occlusive film that helps reduce water loss from the outer layer of the skin (the stratum corneum). It also helps other ingredients like active extracts or vitamins spread more evenly and absorb better. Its emollient properties make the skin feel smoother and more supple without leaving a heavy or sticky residue.
Pros
Lightweight feel
Glyceryl dimyristate provides emollient benefits without a heavy or greasy after-feel, making it ideal for daytime moisturizers and products for oily skin.
Low irritation risk
It has a low irritation and comedogenic rating, so it is generally well-tolerated even by sensitive or acne-prone skin types.
Cons and cautions
Limited moisturizing power
As a lightweight emollient, it may not be sufficient as the sole moisturizer for very dry or compromised skin barriers.
Synthetic origin
Although derived from natural fatty acids, it is produced through chemical synthesis, which may be a concern for those seeking exclusively natural ingredients.
Best for
- People with normal to oily skin looking for a lightweight moisturizer
- Those who prefer non-greasy, fast-absorbing skincare products
Use caution if
- Individuals with very dry or dehydrated skin may need a richer emollient in addition
Usage tips
Safety summary
Glyceryl dimyristate has a low irritation and comedogenic profile. It is considered safe for use in cosmetics at typical concentrations. No significant safety concerns have been reported in clinical or consumer use.
Research notes
Research on glyceryl dimyristate is limited but consistent with other fatty acid esters. Studies show it functions effectively as an emollient and skin conditioning agent with minimal irritation potential. It is widely used in commercial formulations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Moisturizers, Creams, Lotions, Lip products, Makeup
- Environmental note
- Produced from renewable plant-based fatty acids, but the synthesis process may involve chemical reagents. Biodegradability is expected to be moderate.
Good to know
- Glyceryl dimyristate is often used in combination with other emollients to achieve a specific texture or feel.
- It is considered safe for use in cosmetics by major regulatory bodies including the FDA and the European Commission.
