FLUORESCENT BRIGHTENER 230.

Avoid CAS 27344-06-5 / UV ABSORBER

Fluorescent Brightener 230 is an optical agent designed to absorb invisible ultraviolet (UV) light and re-emit it as visible blue or blue-violet light. This optical phenomenon serves to neutralize yellowish undertones, contributing to an immediate perception of brighter, whiter-looking skin. It can also visually minimize the appearance of dark spots or uneven tone.

UV absorber Color-correcting agent Optical brightener

Science

Mechanism of Action

This compound functions by absorbing energy from the invisible ultraviolet (UV) spectrum. Upon absorption, it undergoes fluorescence, re-emitting this energy as visible blue or blue-violet light. The re-emitted blue light acts as a color corrector, optically neutralizing yellow pigmentation in the skin. This leads to an enhanced perception of brightness and a more uniform, whiter complexion, potentially reducing the visible contrast of dark spots.

Fluorescent Brightener 230 exhibits good stability. Related stilbene-type fluorescent brighteners demonstrate stability in aqueous solutions across pH 4, 7, and 9 for periods exceeding one year at 25 °C, suggesting similar resilience for this compound.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Fluorescent Brightener 230 lacks specific safety assessments from the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS). The FDA advises patch-testing products containing optical brighteners due to potential sensitivities. It is prohibited as a food additive in the US and other regions. EWG's Skin Deep database lists it as 'Restricted' for verified products, citing concerns about 'Enhanced skin absorption.' General toxicological data on fluorescent brighteners suggest potential developmental toxicity and altered gene expression in zebrafish. It may persist on human skin, potentially causing irritation, and repeated skin exposure combined with UV radiation has been linked to carcinogenesis in mice. Furthermore, some fluorescent brightening agents are classified as persistent, bioaccumulative, and toxic (PBT) chemicals by the USEPA.

Our Assessment

Verdict

Avoid

Due to the absence of comprehensive safety data from regulatory bodies and significant toxicological concerns, including potential for irritation, enhanced skin absorption, and evidence of genotoxicity and carcinogenesis under specific conditions, this ingredient is not suitable for precision skincare formulations.
