Question 1

What does Menthyl Undecenoyl Dipeptide-16 do in a cosmetic formula?

Accepted Answer

This ingredient is a sensory active and skin-conditioning agent, used to create a mild cooling signal while helping formulas feel calming on reactive or uncomfortable skin.

Question 2

Is Menthyl Undecenoyl Dipeptide-16 clean?

Accepted Answer

Clean-beauty programs generally treat it as acceptable when used at low levels, with the main caveat that cooling actives can feel prickly or sensitizing for some users. It is not a common restricted-list ingredient, but it is more specialized and less broadly benchmarked than simple humectants or emollients.

Question 3

Is Menthyl Undecenoyl Dipeptide-16 sustainable?

Accepted Answer

This material is a semi-synthetic lipopeptide-like compound, typically built from fatty, menthol-derived, and amino-acid components. It is not known for major persistence concerns, but public biodegradation and sourcing data are more limited than for simpler plant oils or mineral ingredients.

Question 4

Is Menthyl Undecenoyl Dipeptide-16 COSMOS-approved?

Accepted Answer

This ingredient may be available in COSMOS-accepted commercial grades, but status depends on the supplier, feedstocks, and processing route. From a Green Chemistry view, it has some favorable features because it can use bio-based building blocks, though it is still a specialty processed active rather than a minimally transformed material.

Question 5

How does Menthyl Undecenoyl Dipeptide-16 work chemically?

Accepted Answer

The molecule combines a cooling it moiety, an unsaturated fatty chain, and a short peptide segment, giving it both lipophilic skin affinity and neurosensory activity. It is typically used at very low active levels through supplier blends, and formulators should check carrier compatibility, solubility, and sensory intensity in the finished product.
