Product Introduction
Main Functions
Water Soluble Pterostilbene is Yihe Biomedical's main product that comes in 2%, 6%, and 8% percentages. Compared to typical high-purity Pterostilbene, this product line is more suitable for those customers looking for easier handling in the water-based and dispersion-sensitive formulas. Its use refers to those product developers wishing to use Pterostilbene functions but, at the same time, needing a specification that more closely fits a beverage, powder drink, food, health product, or cosmetic formulation.
Besides the antioxidant properties, the anti-inflammatory and melanin inhibition capabilities, spot care, and anti-ultraviolet positioning, are also expected based on the water-soluble Pterostilbene provided information. Tast, appearance, and cost harmonization are important constraints when the lowest EP level is chosen in the range of possible 2%, 6%, and 8% inducements. Higher specifications are otherwise desirable if the formula has to obtain a strong active-agent-targeting capability.
Application Areas
Water Soluble Pterostilbene primarily finds its application in the fields of pharmaceuticals, food, health products, and cosmetics. During the development of food and health products, it may be used for solid drink formulations, instant powder blends, capsules, tablets, granules, and other such products where water-soluble active ingredients are a preferred choice. In the case of cosmetics, it may be tried apart from the proposition of antioxidant based skincare products to areas of melanin control, targeting of spots, and anti-ultraviolet themes through the products.
As the pH of a solution, temperature, presence of other chemical substances, and mode of processing may still influence the behavior of water-soluble ingredients, sample testing before actual production is highly recommended. Customers will be able to evaluate clarity, dispersion, effect on color, stability of the formula, and compatibility in pleasure with their own product systems.
