In plain English

Myreth-3 Palmitate is a lab-made ingredient that helps creams and lotions feel silky and spread smoothly on your skin. It works by softening the skin's surface and helping other ingredients mix well. However, because it can be moderately clogging for pores, people with oily or acne-prone skin may want to use it with caution.

Quick decision guide

Useful, but context matters

Myreth-3 Palmitate 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 Myreth-3 Palmitate.
  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

Myreth-3 Palmitate is a synthetic ester derived from myristyl alcohol and palmitic acid, modified with ethylene oxide. It functions as an emollient and surfactant in cosmetic formulations.

How it works

It reduces friction on the skin, making products easier to apply, and helps stabilize emulsions so water and oil ingredients stay mixed. It also leaves a soft, non-greasy feel.

Pros

Smooth texture

Creates a silky, pleasant feel on the skin, making products more enjoyable to apply.

Good emulsifier

Helps keep oil and water ingredients mixed, improving product stability and consistency.

Cons and cautions

May clog pores

Rated as moderately comedogenic, meaning it could contribute to breakouts for acne-prone individuals.

Synthetic origin

Made through chemical processing, which may not align with preferences for natural or minimal-ingredient routines.

Best for

  • People with dry or normal skin looking for smooth-textured moisturizers
  • Those who enjoy lightweight, non-greasy lotions

Use caution if

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

Usage tips

Patch test if you have acne-prone skin before using a product with this ingredient regularly.
Use in moisturizers or cleansers designed for normal to dry skin types for best results.

Safety summary

Myreth-3 Palmitate is considered safe for use in cosmetics at typical concentrations. The main concern is its moderate comedogenic rating, which may cause breakouts in sensitive or acne-prone individuals. No significant toxicity or irritation has been reported in standard use.

Research notes

Limited peer-reviewed studies specifically on Myreth-3 Palmitate, but it is a well-known ingredient in cosmetic chemistry. Comedogenicity ratings are based on historical rabbit ear tests and human patch tests, which indicate moderate pore-clogging potential. Safety assessments by cosmetic ingredient review panels support its use.

Common label clues

Typical concentration
Typically 0.5% to 5% in leave-on products
Regulatory status
Approved for use in cosmetics in the US, EU, and other major markets, with no specific restrictions at typical concentrations.
