Natural Skin Moisturizing Agent Phloretin 98% CAS 60-82-2 98%min

Product Description:

Phloretin is a dihydrochalcone,a type of natural phenol. Phloretin is a member of the class of dihydrochalcones that is dihydrochalcone substituted by hydroxy groups at positions 4, 2′, 4′ and 6′. It has a role as a plant metabolite and an antineoplastic agent. It derives from a dihydrochalcone.

Phloretin is a plant polyphenol with a dihydrochalcone structure. It is present in the peel and root bark of succulent fruits such as apples and pears, and in various vegetable juices. Phloretin has abundant biological activities, such as anti-oxidation, anti-tumor, blood sugar lowering, blood vessel protection, etc. And Phloretin can inhibit tyrosinase activity, enhance skin permeability. It also helps other whitening ingredients to enter the skin to exert their biological activity. At the same time, Phloretin can scavenge free radicals, reduce the keratinocytes damage caused by ultraviolet rays; and it also has antibacterial activity. It has many beauty effects including anti-aging, whitening skin, anti-inflammation, and removing acne. Phloretin can dilute pigmentation and whiten skin. Its effect is better than other common whitening agents such as kojic acid and arbutin. It is a new favorite whitening agent in cosmetics market.

Applications and benifits:
Phloretin is a new type of natural skin whitening agent developed recently in foreign countries. Phloretin has antioxidant, anti-inflammatory, sunscreen, promoting skin absorption, whitening, moisturizing, antibacterial and anti hair loss effects, It can be used in all kinds of cosmetics, so it will be widely used in many kinds of cosmetics and nursing products, such as facial mask, lotion, cream, cream, sunscreen, shampoo and conditioner.
