Ingredient review
Polyglyceryl-10 Dimyristate
INCI: Polyglyceryl-10 Dimyristate
A mild, non-irritating emulsifier that helps create stable, creamy textures without stripping the skin.
In plain English
Polyglyceryl-10 Dimyristate is a gentle emulsifier made from glycerin and myristic acid (a fatty acid found in coconut oil). Its job is to help water and oil mix together in a product so it stays smooth and doesn't separate. Because it's derived from natural sources and has a large, mild molecule, it's very unlikely to cause irritation or clog pores, making it a great choice for sensitive or acne-prone skin.

Quick decision guide
Easy yes for most routines
Polyglyceryl-10 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 Polyglyceryl-10 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 semi-synthetic emulsifier created by combining glycerin (from plant oils) with myristic acid (a fatty acid from coconut or palm kernel oil). It belongs to the polyglyceryl ester family, known for being exceptionally mild.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. This creates a smooth, creamy texture in lotions and creams. It also helps other ingredients spread evenly on the skin and can leave a soft, non-greasy feel.
Pros
Exceptionally gentle
Its large molecular structure means it's unlikely to penetrate the skin or cause irritation, making it ideal for sensitive skin.
Non-comedogenic
It does not clog pores, so it's safe for acne-prone and oily skin types.
Cons and cautions
Semi-synthetic origin
While derived from natural sources, it undergoes chemical processing, which may not appeal to those seeking 100% natural ingredients.
Potential palm oil sourcing
Myristic acid is often derived from palm oil; unless certified sustainable, this can raise environmental concerns.
Best for
- Anyone with sensitive or reactive skin looking for gentle cleansers or moisturizers
- People with acne-prone skin who need non-comedogenic formulas
Use caution if
- Those seeking a completely natural, unprocessed ingredient (it is semi-synthetic)
Usage tips
Safety summary
