What is Butylated Hydroxytoulene (BHT): Chemical Free Living

What is Butylated Hydroxytoulene (BHT)?

Butylated hydroxytoulene (BHT) is a synthetically produced preservative used to keep fats and oils in personal care products and foods from going rancid. Along with BHA, it is a butylated compound.

What products is butylated hydroxytoulene (BHT) in?

BHT is in cosmetics like lip glosses and lotions, personal care items, as well as food items like preserved meats or chips, edible fats, dehydrated foods, baked goods, snack foods, chewing gum, animal feed, and foods that contain fats as well as flavoring products [1] [3]. It is also in food packaging, rubber, and petroleum products [1].

How to tell if a product has butylated hydroxytoulene (BHT)

Look for butylated hydroxytoulene or BHT on the labels [2].

Risks associated with butylated hydroxytoulene (BHT)

BHT mimics the hormone estrogen and as such, the International Agency for Research on Cancer as well as the National Toxicology Program have classified these substances as possible and/or likely human carcinogens. Humans can absorb BHT  from foods as well as through the skin when cosmetics products like lip glosses or lotions contain it as a preservative [1] [3]. As an endocrine disrupter BHT can cause any of the following to occur:

  • Lower testosterone levels
  • Lover thyroxin levels
  • Adversely affect sperm quality [3]
  • Behavioral problems in children [2]

How to avoid butylated hydroxytoulene (BHT)

Read labels on food and cosmetics products to avoid butylated hydroxytoulene and BHT [1]. Instead look for toxic chemical free personal care options by using EWG’s Skin Deep Database. Choose whole foods rather than foods that contain preservatives like BHT.
