There is about 57% bilberry extract, 3% sugar maple extract, 8% lemon extract, 24% sugar cane extract, and 8% orange extract, which results in 28% to 32% lactic acid, 2% to 6% citric acid, 1% tartaric acid, 12% to 17% glycolic acid, and no more than 1% malic acid. It's about 55% active, meaning that 10% Multifruit BSC works out to 5.5% AHA.
As this product can make you more sun sensitive, remember to wear sunscreen or products containing sunscreens if you're going outdoors! (And don't make your own sunscreen!)
Multifruit BSC has a pH of 4.06, and is soluble in water, glycerin, and propylene glycol, and insoluble in oils. Add at 5% to 15% (so 2.75% to 8.25% AHA in your creation) in the cool down phase of your creation. It is great for use in surfactant blends, lotions, creams, shampoos, and other water based creations. It is not suggested to use a cationic emulsifier like BTMS with this product, so keep it in non-ionic lotions and potions or anionic surfactant creations. It has a shelf life of 12 to 18 months if kept in a cool dark place.
