HYDROXYPROPYLTRIMONIUM WASABIA JAPONICA EXTRACT.

Insufficient Data / HAIR CONDITIONING, SKIN CONDITIONING, SKIN PROTECTING

Hydroxypropyltrimonium Wasabia Japonica Extract is a cationic derivative of the Wasabia Japonica plant, designed to deliver multi-faceted benefits to both skin and hair. It functions as a powerful antioxidant, antimicrobial agent, and anti-inflammatory, while also providing conditioning and protective properties.

Hair Conditioning Skin Conditioning Skin Protecting Antioxidant Antimicrobial Anti-inflammatory

Science

Mechanism of Action

This ingredient acts as a formidable antioxidant by actively stimulating the skin's inherent phase II detoxification enzymes and directly mitigating oxidative stress. Its antimicrobial efficacy is attributed to active isothiocyanates, notably Sinigrin and Allyl Isothiocyanate, which are effective against various microorganisms. Furthermore, it demonstrates anti-inflammatory benefits, helping to calm irritated skin and reduce redness, alongside contributing to the conditioning and protection of skin and hair. Related fermented forms may also positively influence the skin's microbiome.

Key findings

  1. 01 Initial research indicates that related Wasabia Japonica extracts are utilized in concentrations of 1-5% for anti-aging, anti-acne, and after-sun applications, also exhibiting significant antimicrobial effects. It is important to note that these findings are primarily associated with Wasabia Japonica Root Extract or Lactobacillus/Wasabia Japonica Root Ferment Extract, rather than the specific Hydroxypropyltrimonium modified form.

Stability

The Hydroxypropyltrimonium modification is generally understood to enhance water solubility and stability within aqueous formulations. For a closely related ingredient, Lactobacillus/Wasabia Japonica Root Ferment Extract, optimal activity is suggested within a pH range of 4.0 to 7.0.

Conflicts

  • Due to its cationic nature, potential incompatibilities with highly anionic ingredients (e.g., Carbopol, Xanthan gums, Carrageenan, Hyaluronic Acid) may lead to haziness or precipitation.
