Ethyl Ascorbic Acid

Ethyl Ascorbic Acid is an etherfied derivative of ascorbic acid,one of the most stable derivates of ascorbic acid.,this type Viatmin C  consists of vitamin C and an ethyl group bound to the third carbon place. This element makes vitamin c stable and soluble not only in water but also in oil. Ethyl Ascorbic Acid is considered to be the most desirable form of Vitamin C derivatives as it is highly stable and non-irritating .It’s also showing a very good stability in all kinds of cosmetic formulations. Ethyl Ascorbic Acid penetrates into skin where it is metabolized to ascorbic acid.Due to this process its efficacy is more pronounced than the one of pure ascorbic acid.Non irritating to skin and eyes.

Ethyl Ascorbic Acid,3-O-Ethyl Ascorbic Acid, a form of ethylated vitamin C,is an excellent skin whitening agent,it inhibits the activity of Tyrosinase by acting on Cu2+ and it prevents the synthesis of melanin.It is an etherfied derivative of ascorbic acid,one of the most stable derivates of ascorbic acid.It’s also showing a very good stability in all kinds of cosmetic formulations.

Ethyl Ascorbic Acid is an effective whitening agent and anioxidant,that is metabolized by the human boday in same mannaer as regular Vitamin C.Vitamin C is a water-soluble antoxidant but can not be dissolved in any other organic solvents because it is structurally unstable,with limited applications.However,Ethyl Ascorbic Acid dissolves in a variety of solvents including water,oil and alcohol and therefore can be mixed with any prescribed solvents.It can be applied to suspension,cream,lotion,serum,water-oil compund lotion,lotion with solid materials,masks,puffs and sheets.

Vitamin C:

Nowdays Various vitamin C derivatives are used in cosmetics for external use . Pure vitamin C, ascorbic acid or also called L-ascorbic acid (ascorbic acid) has the most direct effect.In contrast to the other variants, it does not first have to be converted into the active form. Studies show that vitamin C supports collagen synthesis and fights free radicals. It is also effective against acne and age spots by inhibiting tyrosinase. However, ascorbic acid cannot be processed into a cream because the active ingredient is too susceptible to oxidation and decomposes quickly. Therefore, preparation as a lyophilisate or administration as a powder is expedient.

In the case of a serum containing ascorbic acid, the formulation should have a strictly acidic pH value to ensure the best possible penetration into the skin. The administration should be an airtight dispenser. Vitamin C derivatives that are less skin-active or more tolerable and that remain stable even in cream bases are particularly suitable for sensitive skin or the thin eye area.

It’s well known that a high concentration of an active ingredient does not mean a better care effect. Only the careful selection and the formulation adapted to the active ingredient ensure optimal bioavailability, good skin tolerance, high stability, and the best possible product performance.
