Answer
Alternatives for Butylated Hydroxy Toluene (BHT)
Butylated Hydroxy Toluene (BHT) is commonly used as an antioxidant in formulations. If you are using BHT for its antioxidant properties, Vitamin E Acetate (Tocopheryl Acetate) is a suitable alternative.
Based on product information, Vitamin E Acetate helps protect ingredients from deterioration due to oxidation. It is available in both oil-soluble and water-soluble forms.
For use as an antioxidant to protect other oils in a formula, a recommended usage rate is 0.01%. If used for its antioxidant benefits on the skin, a usage rate of 0.1-0.5% is suggested. The total usage rate can be up to 1%. Using more than 0.5% might result in a sticky feeling on the skin.
Other types of antioxidants are also available, including dl-alpha Tocopherol, Rosemary Oleoresin Extract, and various Protec™ types, each offering different characteristics and levels of efficiency.
