GLYCIDOXYPROPYL TRIMETHOXYSILANE/PEI-250 CROSSPOLYMER FLUORESCENT BRIGHTENER 230 SALT.

Questionable / COLORANT, OPACIFYING

This ingredient is a polymeric fluorescent brightener designed to visibly enhance skin radiance. It functions by converting invisible UV light into blue light, which effectively neutralizes yellow undertones, resulting in a brighter and clearer skin appearance. It also acts as a cosmetic colorant and opacifying agent.

Summary

colorant opacifying skin brightening

Science

Mechanism of Action

Fluorescent brighteners, also known as optical brightening agents, operate by absorbing photons from the invisible ultraviolet (UV) spectrum. Subsequently, they re-emit this energy as visible blue light. This emitted blue light visually counteracts and neutralizes the natural yellowish tones present in the skin, thereby creating an optical illusion of whiter, brighter, and clearer skin. The underlying molecular process involves specific π→π* electron transitions within the conjugated system of the brightener molecules.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) has not conducted a specific review for 'GLYCIDOXYPROPYL TRIMETHOXYSILANE/PEI-250 CROSSPOLYMER FLUORESCENT BRIGHTENER 230 SALT'. General data for Fluorescent Brightener 230 suggests potential irritation to skin, eyes, and the respiratory system, particularly in its solid form. There are concerns that general fluorescent brighteners may persist on human skin and potentially induce irritation upon repeated exposure. Furthermore, studies in mice have indicated a potential association between repeated exposure to fluorescent brighteners combined with UV radiation and carcinogenesis. Some brighteners are classified as persistent, bioaccumulative, and toxic (PBT) chemicals by the USEPA. EWG Skin Deep rates 'Fluorescent Brightener 230' with low-moderate concern for cancer and low concern for allergies/immunotoxicity and developmental/reproductive toxicity, recommending restriction for EWG VERIFIED products without adequate substantiation.
