Ingredient review

Methylacetyl Methylpropanoyl Ethylcarbamate

INCI: METHYLACETYL METHYLPROPANOYL ETHYLCARBAMATE

A synthetic skin-conditioning agent with limited research; generally considered safe at low concentrations but not widely studied.

beautyskincareconditioning agent

In plain English

This is a man-made ingredient that helps make your skin feel smoother and softer. It belongs to a family of chemicals called carbamates, which are used in small amounts in skincare products. Because it's not a natural extract, it's designed to be stable and consistent in formulas. However, there isn't a lot of independent research on how well it works or its long-term effects, so it's best to approach it with cautious optimism.

Quick decision guide

Useful, but context matters

Methylacetyl Methylpropanoyl Ethylcarbamate 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Methylacetyl Methylpropanoyl Ethylcarbamate.
  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

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A synthetic carbamate compound created in a lab, used primarily as a skin-conditioning agent to improve the feel and texture of skincare products.

How it works

It forms a thin, flexible film on the skin's surface, which helps reduce water loss and gives a temporary smoothing effect. It may also help other ingredients spread more evenly.

Pros

Smooths skin feel

Creates a temporary silky, soft finish on the skin, which can improve the texture of moisturizers and serums.

Stable in formulas

As a synthetic ingredient, it doesn't degrade easily, helping products maintain their effectiveness over time.

Cons and cautions

Limited research

There are few peer-reviewed studies on this specific compound, so its long-term benefits and safety are not well-documented.

Not natural

For those who prefer plant-based or naturally derived ingredients, this synthetic compound may be less appealing.

Best for

  • People looking for a lightweight skin-smoothing agent
  • Those who tolerate synthetic ingredients well

Use caution if

  • Individuals with very sensitive or reactive skin
  • Those who prefer exclusively natural ingredients

Usage tips

Use in products with other well-studied humectants like glycerin for balanced hydration
Patch test before widespread use if you have sensitive skin

Safety summary

Generally considered safe at low concentrations based on limited data, but there is no long-term human safety data available. Skin irritation is rare but possible.

Research notes

Very few published studies exist on this specific ingredient. Most safety data comes from general carbamate chemistry rather than direct cosmetic testing.

Common label clues

Typical concentration
Typically used at low concentrations (0.1%–2%)
Regulatory status
Approved for use in cosmetics in the EU and US at low concentrations, but not specifically reviewed by the Cosmetic Ingredient Review panel as of 2025.
Common uses
Moisturizers, Anti-aging creams, Serums
Environmental note
As a synthetic compound, its biodegradability and environmental impact are not well-studied; it may persist longer than natural alternatives.

Good to know

  • This ingredient is not commonly found in drugstore products; it's more typical in high-end or niche formulations.
  • Its name is a mouthful, but it's just a chemical description of its molecular structure.
