INCI: Propylene Glycol Myristate

A synthetic emollient that softens skin and improves product feel, but may clog pores for some people.

In plain English

Propylene Glycol Myristate is a man-made ingredient that helps moisturizers and creams feel smooth and spread easily on your skin. It works by forming a light, non-greasy film that softens the skin's surface. However, because it is an ester, it can be moderately comedogenic, meaning it might clog pores in people prone to acne.

Quick decision guide

Useful, but context matters

Propylene Glycol Myristate can be useful, but watch for possible clogging concerns.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Propylene Glycol Myristate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Propylene Glycol Myristate is a synthetic ester created by combining propylene glycol with myristic acid (a fatty acid found naturally in coconut oil and palm oil). It is a clear, oily liquid used in cosmetics to improve texture and provide a silky feel.

How it works

It sits on the skin's surface as an emollient, filling in gaps between skin cells to make the skin feel smoother and softer. It also helps other ingredients spread evenly and can reduce the greasy feel of heavier oils.

Pros

Smooth texture

Creates a silky, non-greasy feel that makes products pleasant to apply and wear.

Good spreadability

Helps creams and lotions glide over the skin evenly, improving the user experience.

Cons and cautions

Potential pore clogging

Rated moderately comedogenic, so it may cause breakouts in acne-prone individuals.

Synthetic origin

Made in a lab, which may be a drawback for those seeking exclusively natural ingredients.

Best for

  • People with normal to dry skin looking for a lightweight emollient
  • Those who enjoy rich, smooth textures in moisturizers

Use caution if

  • People with oily or acne-prone skin who are sensitive to pore-clogging ingredients

Usage tips

If you have acne-prone skin, patch test products containing this ingredient before full-face use.
Look for it in moisturizers and creams where a smooth, non-sticky finish is desired.

Safety summary

Generally considered safe for most skin types at typical use levels. The main concern is its moderate comedogenic potential, which may cause breakouts in susceptible individuals. Irritation is rare.

Research notes

Propylene Glycol Myristate has been used for decades in cosmetics. Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found it safe as used. Comedogenicity ratings are based on historical rabbit ear and human patch tests, indicating moderate potential for pore clogging.
