The effect of ascorbic acid effectively solves the fat solubility problem of ascorbic acid, and is widely used in cosmetics as a whitening agent and antioxidant. Uses 3-O-Ethyl-L-ascorbic Acid could be a useful stabilizing agent for a para-hydroxyacetophenone solution. It could be a useful ...
More importantly, this two solubility makes it easier to penetrate the cuticle and enter the dermis, so as to play its biological effect, which is the result of other vitamin C derivatives What we don't have. It can block the formation of melanin by inhibiting the activity of tyrosinase; ...
The compound 3-o-ethyl-l-ascorbic acid (EA) has been developed as a stable vitamin C derivative and has been used in topical products. The aims of this work were to conduct a comprehensive characterisation of physicochemical properties of EA as well as to investigate the influence of various...
Interestingly, lactic acid, tartaric acid & malic acid, have important roles as a crosslinker as they enhance the mechanical as well as biological properties such as bactericidal activity, optical properties, hygroscopicity, and aqueous solubility, which are essential for food packaging material. ...
combinations of propyl gallate, butylated hydroxyanisole, butylated hydroxytoluene, and citric or ascorbic acid. A concentration of 0.03% w/v of a mixture of propyl gallate (37.5%), butylated hydroxytoluene (37.5%), and butylated hydroxyanisole (25%) was found to be the best antioxidant for ...
BHA and L-ascorbic acid were used as standard antioxidants. Figure 2. Antibacterial (a, b) and antifungal activity (c, d) of aqueous and ethyl acetate extracts of stems, leaves and flowers (A1 and E1, respectively) and leaves and flowers (A2 and E2, respectively) of S. kitai...
