NEOHESPERIDIN DIHYDROCHALCONE.

Valuable CAS 20702-77-6 / FLAVOURING, FRAGRANCE, PERFUMING

Neohesperidin Dihydrochalcone (NHDC) is a potent flavonoid derivative, recognized for its significant antioxidant and anti-inflammatory capabilities. It functions as a skin-conditioning agent, promoting a smoother texture and enhanced hydration, while also showing promise in reducing lipid accumulation.

Science

This ingredient actively scavenges various reactive oxygen species (ROS), notably acting as a strong inhibitor of H2O2 and HOCl. Its mechanism involves activating the Nrf2 pathway, which subsequently upregulates the production of crucial antioxidant enzymes like HO-1 and NQO-1, thereby mitigating oxidative stress. Upon metabolic conversion, its metabolite, dihydrocaffeic acid (DHCA), demonstrates an anti-inflammatory effect by significantly down-regulating pro-inflammatory cytokines such as IL-6 and TNF-α. Additionally, NHDC contributes to skin conditioning, aiding in the softening and smoothing of the skin's surface.

Transparency

Not commonly dusted

Neohesperidin Dihydrochalcone is a recognized ingredient with documented skin-conditioning properties and in vitro demonstrated antioxidant, anti-inflammatory, and lipid-reducing activities. Its established use in cosmetic formulations, alongside its use as a sweetener, indicates it is included for specific dermatological benefits rather than as a 'dusting' ingredient.

Stability

NHDC exhibits stability under normal processing and storage conditions, particularly in neutral formulations and moderate thermal environments. While its water solubility is sparingly low at neutral pH (0.4 g/L at room temperature), it markedly increases in alkaline media where ionization occurs. It is also soluble in common organic solvents such as ethanol and propylene glycol. Sensitivity to strong acids or prolonged alkaline exposure is noted; for improved aqueous solubility, water-soluble sodium salt forms can be utilized.

Sensitization risk Low

The FDA has issued a 'no objection letter' to its Generally Recognized As Safe (GRAS) status for food use at maximum levels ranging from 0.001% to 0.1% (10-1000 ppm). The European Food Safety Authority (EFSA) re-evaluated NHDC in 2022, establishing an acceptable daily intake (ADI) of 20 mg/kg body weight per day. Safety studies generally indicate it is non-toxic, non-mutagenic, and non-carcinogenic. While a specific SCCS opinion for cosmetic use is not available, EWG reports low concerns for allergies and immunotoxicity.
