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 amide compound derived from myristic acid (a fatty acid) and modified with cetyl and glyceryl groups. It functions as a skin-conditioning agent and emulsifier.

How it works

It reduces the surface tension between oil and water phases in a formula, helping them blend into a stable cream or lotion. On the skin, it forms a thin film that can improve feel and reduce water loss.

Pros

Improves formula stability

Helps oil and water mix evenly, so your product stays consistent and doesn't separate.

Enhances skin feel

Leaves a soft, smooth finish on the skin without heavy greasiness.

Cons and cautions

Limited safety data

There is not a lot of independent research on this specific ingredient, so long-term effects are not well understood.

Synthetic origin

It is lab-made, which may be a concern for those preferring natural or plant-derived ingredients.

Best for

  • People who use moisturizers or cleansers and want a smooth, non-greasy feel
  • Those looking for stable, well-mixed formulas

Use caution if

  • Individuals with known sensitivities to synthetic amides or fatty acid derivatives

Usage tips

Use as part of a well-formulated product; it's not typically sold as a standalone ingredient.
Patch test new products containing this ingredient if you have sensitive skin.
