What it is

CAS number 127-51-5 and EC number 204-846-3 help distinguish this substance from similarly named materials. Together, the INCI name, chemical designations and identifiers provide the identity reference available when the ingredient appears in a composition.

What it does in a formula

The recorded classification gives ALPHA-ISOMETHYL IONONE two functions: SKIN CONDITIONING and PERFUMING. The first places it among ingredients associated with skin conditioning, while the second places it in the perfuming category of a cosmetic formula.

Those classifications explain why the substance can be listed in a formula; they do not turn the ingredient name into a claim about a finished product. This entry does not state concentration, combinations with other components or the result of use in a particular package.

Conditions and care

The record associates ALPHA-ISOMETHYL IONONE with cosmetic restriction III/90. This is the only restriction information displayed for this entry: no maximum concentration, condition of use or accompanying text is provided to explain the scope of the code.

The available information therefore supports only a limited reading: a restriction reference is linked to the ingredient. Without the corresponding explanation in the entry, the code cannot be turned into a numerical limit, use instruction or conclusion about safety.
