About IMIDAZOLYLPHENYLETHYL NAPHTHYLSULFONYL ASPARAGINE
A proprietary synthetic peptide-like conditioner used in anti-ageing formulas at very low use levels. Limited public data, so caution is in order.
Detailed Analysis
Imidazolylphenylethyl naphthylsulfonyl asparagine (CAS 1190428-65-9) is a synthetic amino-acid-derived molecule, typically marketed as a proprietary skin-conditioning or signalling peptide-mimetic. It is used at very low use levels (often <1%) to support anti-ageing claims. Public peer-reviewed toxicology, CIR, and SCCS data are not available, and the INCI entry is essentially a single-supplier proprietary designation. No specific regulatory restriction applies, but the transparency and evidence base are thin. Environmental fate and biodegradability data are unclear.
