Description

Composition with moisturizing and antioxidation effects and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, relates to a composition with moisturizing and antioxidation effects and application thereof, and in particular relates to a composition with moisturizing and antioxidation effects and application thereof in preparing cosmetics.

Background

The skin is gradually aged due to continuous contact with the outside, which includes external pollution, ultraviolet irradiation, etc., which continuously generates free radicals. Free radicals, which are the products of human cellular metabolism, are destructive to unsaturated fatty acids, protein molecules, nucleic acid molecules, extracellular soluble components, and membrane lipids, resulting in wrinkles, sagging, and subcutaneous fat loss. The free radicals destroy collagen and elastin, so that the skin is moisturized and the function of maintaining elasticity is lost, and the precipitation of melanin is accelerated. Age and certain in vitro factors can cause free radical production in the body and skin tissues to exceed the body's ability to normally scavenge free radicals, thereby causing damage to the skin tissues and resulting in aging.

Meanwhile, when the environment changes, the skin cuticle can not timely adjust enough moisturizing factors, the activity of the grease glands can be reduced, the grease and the moisture on the face can be reduced, the skin can be stretched, and even fine lines appear under eyes and beside eyes. Therefore, in daily skin care, it is necessary to maintain moisture in the skin and reduce loss of moisture in the skin, thereby maintaining a certain water-oil balance state of the skin.

The moisturizing and the antioxidation are important links for maintaining the youthful skin and delaying the aging, and the development of a cosmetic product with both the effective moisturizing and the antioxidation is very significant.

Test example 1

In vitro oxidation resistance experiment:

laboratory instrument and reagent:

the main instrument is as follows: spectronics GENESYS-5, thermo Inc. of America.

The main reagent comprises: DPPH, analytically pure, tianjin metallocene; methanol, analytically pure, tianjin metallocene; ascorbic acid, analytically pure, shanghai nationality drug.

Preparing a solution: first, DPPH 1mg is dissolved in about 20mL of methanol, and the solution is subjected to ultrasonic treatment for 5min and is fully shaken to ensure that the upper part and the lower part are uniform. Taking 1mL of the DPPH solution, and measuring A value at 519nm to ensure that A=1.2-1.3; and preparing various sample solutions: the compositions of examples 1-11 and comparative examples 1-4 were diluted with methanol to prepare a composition having a mass fraction of 1%.

The specific method comprises the following steps: the sample addition systems for each group are shown in the following table, the reaction solution was shaken and then placed in a water bath at 37℃for 15 minutes, and then taken out, and the absorbance value of the solution was measured by an ultraviolet-visible spectrophotometer.

Reagent(s)	C1/mL	C2/mL	C3/mL
				DPPH solution	2	2	0
Sample solution	0	2	2
				Anhydrous methanol	2	0	2

The calculation formula of the DPPH free radical clearance is shown as follows:

DPPH radical scavenging = 1- (A2-A3)/a1×100%

Wherein A1, A2 and A3 are absorbance values of C1, C2 and C3, respectively.

The test results are shown in table 1:

		Example 5	86.9
Example 6	87.6
		Example 7	86.3
Example 8	82.9
		Example 9	82.5
Example 10	80.8
		Comparative example 1	74.1
Comparative example 2	65.3
		Comparative example 3	73.3
Comparative example 4	70.8

As can be seen from the data in table 1: the overall DPPH radical scavenging rate of examples 1-3 was higher than that of comparative examples 1-4, indicating that the DPPH radical scavenging effect was reduced in the absence of either component in the composition; the overall DPPH radical scavenging rate of example 4 was higher than examples 8-10, demonstrating that yeast amino acids, serum albumin, and decarboxylated carnosine hydrochloride also have some synergistic effect on DPPH radical scavenging.

TABLE 3 Table 3

Grade	(symbol)	Authentication criteria
			0	-	Negative reaction: no irritation and erythema
1	±	Suspicious reaction: mild erythema
			2	+	Weak positive reaction: erythema (red spot)
3	++	Strong positive reaction: erythema, papule and blister
			4	+++	Very positive reaction: severe edema, large foam
