  • Personal Care Products Council — INCI Dictionary (Wasabia Japonica entries)
Q. Is the cosmetic extract still pungent / sensitizing?

Cosmetic-grade wasabi extracts are typically processed to remove or reduce allyl isothiocyanate (AITC), the compound responsible for pungency, since AITC is a known skin irritant. Always request a sensitization-relevant impurity spec at qualification.

Q. Is the species (true wasabi vs. horseradish) regulated for marketing claims?

True wasabi (Wasabia japonica / Eutrema japonicum) is geographically scarce and frequently substituted with horseradish + green colorant in food. For cosmetic 'authentic Japanese wasabi' positioning, supplier traceability documents (often from Shizuoka or Nagano growers) are essential.

Q. Are there quasi-drug or major regulatory considerations in Japan?

Wasabi extract is not on 厚生労働省 (Ministry of Health, Labour and Welfare)'s quasi-drug active lists; it is a general cosmetic ingredient. Marketing must stay within general cosmetic claim ranges.
