Abstract:
An additive composition including an anhydrous liquid precursor solution having solubilized salicylic acid therein and a polymer substrate to be added to a base composition to make dermatologic, cosmetic, toiletry, and personal care products, comprising:a) butylene glycol or propylene glycol acting as a solubilizer agent being in the range of 2.5% to 15.0% by weight of the additive composition; b) an anhydrous solvent selected from the group consisting of glycereth-26, glycereth-7, polyethylene glycol 200, polyethylene glycol 400 and polyethylene glycol 600 for acting as a solubilizer agent being in the range of 20.0% to 35.0% by weight of the additive composition; c) salicylic acid for treating and preventing skin-related problems being in the range of 0.5% to 20.0% by weight of the additive composition; d) said salicylic acid being solubilized by said solubilizer agents for forming free salicylic acid molecules within said additive composition; and e) a polymer substrate for receiving therein said butylene glycol or said propylene glycol, one or more of said anhydrous solvents and said free salicylic acid molecules therein and being in the range of 40.0% to 60.0% by weight of said additive composition for use in making dermatological, cosmetic, toiletry, and personal care products.
