Problems solved by technology

The former is inconvenient to use and has certain risks; although the latter can be used in water preparations, studies have shown that ascorbic acid derivatives are not as effective as ascorbic acid
The third is to use anhydrous or silanol-in-oil formula system to prepare, but the experience is poor and the consumer acceptance is low
[0004] (2) At the same time, since the effective concentration of ascorbic acid is irritating to most clinically problematic skins, it is necessary to gradually build tolerance for normal skin, but it cannot be selected for sensitive skin or sub-healthy skin with damaged skin barrier. Similar antioxidant products for skin antioxidant management
[0005] The reasons for the above problems have been analyzed: (1) Reduction of ascorbic acid: Ascorbic acid itself has strong reducibility, its chemical properties are extremely unstable, and under certain conditions (such as heat, alkalinity, light, oxygen, etc.) ) is easily converted into hexose derivatives by oxidation and loses its original reducing property
[0006] (2) Poor skin feel due to anhydrous system: In order to solve the stability problem of ascorbic acid, the formula of alcohol-in-silicone oil or anhydrous system is usually used to prepare antioxidant products. Therefore, the formula is oily and the experience is poor
[0010] In the field of skin anti-oxidation and whitening, the combination of different skin care components is a very common method for skin anti-oxidation and whitening. The combination of different skin care components, according to the actual application effect, in addition to no harm to the human body In addition, it mainly depends on the effect of different groups of people and different skin types. In general, the compounding of different skin care components is an additive effect. There are very few synergistic effects, especially those with obvious synergistic effects. For skin care products, the inventor found that microencapsulated L-vitamins, antioxidants: tocopherol, polylysine glycerin, polyol moisturizers and dipotassium oxalate in a specific ratio will produce a good synergistic effect. It can more effectively scavenge various forms of oxygen free radicals, but how to effectively scavenge oxygen free radicals has not yet been publicly reported

Abstract

The invention discloses an antioxidant skincare composition containing L-vitamin C. The antioxidant skincare composition comprises microencapsulated L-vitamin C, dipotassium glycyrrhizinate, sodium hyaluronate, a polyol moisturizer, a thickener and an antioxidant. Tocopherol, polylysine and the like are adopted as the antioxidant, so that the irritation of the antioxidant penetrating into the skincan be reduced under the action of the polyol moisturizer, and meanwhile, playing of the best activity and permeability of the antioxidant is facilitated; and the tocopherol, the polylysine and the microencapsulated L-vitamin C play a synergistic effect together, so that the free radical scavenging effect is better. Meanwhile, the invention further provides a preparation method of the antioxidantskincare composition containing the L-vitamin C.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to an antioxidant skin care composition containing L-vitamin C and a preparation method thereof. Background technique [0002] At present, skin antioxidant products use antioxidant raw materials such as ascorbic acid, astaxanthin, and coenzyme Q10, but ascorbic acid, also known as vitamin C, is the most powerful antioxidant that can scavenge free radicals. And scavenging free radicals, participate in the synthesis of collagen in the dermis of the skin, and have an effect on the expression of type I and type IV collagen. At the same time, it can prevent the formation of melanin by inhibiting the activity of tyrosinase, and has the effect of whitening. Therefore, it is widely used in the field of skin care products. [0003] (1) A large number of studies have shown that the key to anti-oxidation is to scavenge free radicals, to avoid the oxidative stress respon...
