Chemical Vitamin a Palmitate (1.7M BHT)

Product Description
Vitamin A Palmitate 1.7M (BHT) is a viscous yellow oil at room temperature and soluble in fats and oil. The addition of an antioxidant as t-butylhydroxytoluene (BHT, E321) will stabilize the product. Storage below 20° C will enhance shelf life but may cause crystallization. Gentle warming less than 40° C and thorough mixing before use will melt and homogenize the product.
