Transcript of BHT

Why Is It Used In Cosmetics? BHT acts as an antioxidant by preventing or slowing the deterioration of cosmetics and personal care products caused by chemical reactions with oxygen. What Cosmetics Are It Used In? It can be found in a wide range of cosmetics and personal care products, particularly in makeup products such as eyeliners, eye shadows, eyebrow pencils, lipsticks, blushes, face powders, and foundations, as well as in perfumes, moisturizers, and personal cleanliness products, skin cleansers, and skin care products. BHT Safety Concerns Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion: Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately. Physical and Chemical

BHT is slightly soluble in water and quite soluble in organic oils and solvents. BHT is not flammable but will burn. It is stable under recommended storage conditions. BHT dust is explosive Environmental Concerns/ Toxicity BHT has a low acute aquatic toxicity and is only slightly soluble in water. BHT is not readily degradable in the environment and may bio- accumulate in aquatic organisms, so care must be taken to prevent it from entering surface or ground waters. BHT should be disposed of in accordance with applicable federal, state, and local regulations as a non-hazardous waste. Butylated Hydroxtoluene BHT What is it? BHT (Butylated Hydroxtoluene) is a white to yellowish-white, crystalline solid. BHT:genetic code C 15 H 24 O Impact of The Chemical on Both Land and
Water on Local and Global Scales BHT is directly incorporated into products at low levels and does not readily leach or evaporate from preserved materials. Therefore, BHT once incorporated into products essentially has no environmental impact beyond those posed by the products themselves. What We Think We think that the product could be continued to be used in cosmetics, as long as people knew about the safety precautions, because it has positive effects for the cosmetics and little to no environmental effects.
