PHENYLENE BIS-DIPHENYLTRIAZINE.

Valuable CAS 55514-22-2 / LIGHT STABILIZER, UV FILTER

Phenylene Bis-Diphenyltriazine is a cutting-edge organic UV filter engineered to provide broad-spectrum protection. It effectively shields skin from UVA, UVB, and High Energy Visible Light (HEVL), including blue light, thereby preventing photo-aging and immediate pigmentation.

Summary

UV filter Light stabilizer

Science

Mechanism of Action

This ingredient operates by absorbing harmful UV radiation and transforming that energy into heat, while also reflecting a portion of visible light. This dual action mitigates sun damage and helps preserve skin integrity, further enhanced by its inherent photostability, which ensures sustained protection.

Dusting Analysis

Not commonly dusted

This ingredient is not associated with typical dusting concerns. However, its insoluble nature means it is strictly prohibited in spray or aerosol products to prevent inhalation exposure, as safety data for this route of administration is currently unavailable.

Stability

Phenylene Bis-Diphenyltriazine is renowned for its excellent photostability, meaning it maintains its protective capabilities without significant degradation when exposed to sunlight, ensuring prolonged efficacy.

Conflicts

  • Use in spray or aerosol products is prohibited due to potential inhalation risks and insufficient safety data.
  • Formulations must ensure NMP and hydrazine impurities, classified as CMR 1B (carcinogenic, mutagenic, or toxic for reproduction) and Substances of Very High Concern (SVHC), are maintained at strictly trace levels.

Sensitization risk Unknown

The Scientific Committee on Consumer Safety (SCCS) considers Phenylene Bis-Diphenyltriazine (S86) safe for use as a UV-filter in dermally applied products at concentrations up to 5%. However, its use is not deemed safe in products that could lead to inhalation exposure due to its insoluble nature and lack of inhalation data. Earlier SCCS opinions indicated that a concentration of 10% was not considered safe due to potential genotoxicity concerns, and tests for eye irritation and skin sensitization were deemed inconclusive. Strict control over trace impurities of NMP and hydrazine is essential due to their classification as CMR 1B and SVHC.
