Butylated Hydroxytoluene

Butylated Hydroxytoluene (BHT) — synthetic antioxidant/preservative. Debated ingredient: possible carcinogen under some classifications, frequently on "avoid" lists for sensitive skin. Use with caution.

Butylated Hydroxytoluene is classified as use with caution — it can be a valuable ingredient, but is more likely to cause irritation or sensitivity for some skin types than a plain "safe" ingredient, so patch testing is worth doing first.

Butylated Hydroxytoluene has a comedogenic rating of 0 out of 5, meaning it is not known to clog pores and is generally considered safe for acne-prone skin.

Butylated Hydroxytoluene is classified as an antioxidant in the Pure Moonlight ingredient database. That classification reflects its primary functional role in a skincare formula.
