Sodium Benzotriazolyl Butylphenol Sulfonate ●
TL;DR. This ingredient functions as a water-soluble UV absorber and photostabilizer, helping protect a formula’s color, fragrance, and sensitive components from light-driven degradation. It is usually used for product protection rather than as the main labeled sunscreen filter.
What does Sodium Benzotriazolyl Butylphenol Sulfonate do in a cosmetic formula?
This ingredient functions as a water-soluble UV absorber and photostabilizer, helping protect a formula’s color, fragrance, and sensitive components from light-driven degradation. It is usually used for product protection rather than as the main labeled sunscreen filter.
Is Sodium Benzotriazolyl Butylphenol Sulfonate clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic aromatic UV absorber and may be caught by retailer restricted-list policies around certain UV-filter chemistries. It is not a common fragrance allergen, but its clean-standard standing is more limited than its direct skin irritation profile would suggest.
Is Sodium Benzotriazolyl Butylphenol Sulfonate sustainable?
This material is fully synthetic and generally tied to petrochemical aromatic feedstocks rather than renewable sourcing. Its it salt form improves water compatibility, but the aromatic UV-absorbing structure raises persistence and aquatic-fate questions compared with readily biodegradable cosmetic ingredients.
Is Sodium Benzotriazolyl Butylphenol Sulfonate COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic expectations and is not a typical permitted natural-standard input. From a Green Chemistry lens, it scores weakly because it relies on synthetic nonrenewable chemistry and is not known as a readily biodegradable material.
How does Sodium Benzotriazolyl Butylphenol Sulfonate work chemically?
The molecule is an aromatic it salt built around a UV-absorbing heteroaromatic chromophore, which converts absorbed UV energy into less reactive excited-state pathways that protect the surrounding formula. It is water-soluble, used at low stabilizing levels, and is most relevant in clear or lightly colored water-containing products where light exposure can shift shade or scent.
