Butylated Hydroxytoluene ●
TL;DR. This ingredient is an antioxidant stabilizer used to slow oxidation in oils, waxes, fragrances, and colorants, helping prevent rancid odor, color shift, and formula degradation.
What does Butylated Hydroxytoluene do in a cosmetic formula?
This ingredient is an antioxidant stabilizer used to slow oxidation in oils, waxes, fragrances, and colorants, helping prevent rancid odor, color shift, and formula degradation.
Is Butylated Hydroxytoluene clean?
From a clean-beauty perspective, it is often flagged or restricted because it is a synthetic phenolic antioxidant with ongoing endocrine-screening debate. It is legally allowed in cosmetics at low levels, but many clean frameworks prefer less controversial antioxidant systems.
Is Butylated Hydroxytoluene sustainable?
This material is typically petroleum-derived and not readily biodegradable. Its environmental profile is less aligned with modern low-persistence ingredient preferences, especially for rinse-off products.
Is Butylated Hydroxytoluene COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its petrochemical origin and limited biodegradability make it a weak fit with Green Chemistry priorities, even though it is used at very low concentrations.
How does Butylated Hydroxytoluene work chemically?
The molecule is an oil-soluble hindered phenol, with bulky alkyl groups that help it donate hydrogen to lipid or fragrance radicals and slow oxidative chain reactions. Typical use levels are often around 0.01% to 0.1%, and it is usually added to the oil phase where it remains more relevant than pH-driven behavior.
