Description

Preservative-free facial moisturizing composition and preparation method thereof

Technical Field

The invention relates to a facial moisturizing composition without preservatives and a preparation method thereof, and belongs to the technical field of skin care products.

Background

The facial mask is a category of skin care products, is a carrier of the skin care products, is applied on the face for beautifying functions such as moisturizing, whitening, anti-aging, grease balancing and the like, under the condition of continuous development of social economy, people pay more attention to self care, and the rate of increase of imported cosmetics in China is remarkably increased in two years, wherein the rate of increase of the facial mask in each year is over 24.6 percent and is far higher than the global increase rate. The principle of the facial mask is that the facial mask is covered on the face for a short time, so that outside air and pollution are temporarily isolated, the skin temperature is increased, pores of the skin are expanded, sweat gland secretion and metabolism are promoted, the oxygen content of the skin is increased, products of epidermal cell metabolism and accumulated grease substances are favorably removed from the skin, water in the facial mask permeates into the horny layer of the epidermis, the skin becomes soft, and the skin is naturally bright and elastic. The facial mask mainly has four types, namely a paste type, a tearing type, a jelly type and a wet tissue type. The mud paste type mask and the gel type mask are popular in the market due to the advantages of high moisture retention, flexible use mode and the like.

Further, the humectant is at least one of sodium hyaluronate, glycerin and propylene glycol.

Further, the humectant is 1-3 parts of sodium hyaluronate, 1-3 parts of glycerin and 0-4 parts of propylene glycol.

Further, the film forming agent is pullulan.

The second purpose of the invention can be achieved by adopting the following technical scheme: a method of preparing a preservative-free facial moisturizing composition as described above, comprising:

a material mixing step: adding the effective components into a dry material mixer for mixing, and then adding distilled water to obtain mixed slurry;

grinding: grinding the slurry in a colloid mill, standing and defoaming to obtain paste;

and (3) sterilization: sterilizing the paste at high temperature to obtain the facial moisturizing composition without preservative.

Further, in the step of mixing materials, the temperature of adding distilled water is 40-60 ℃.

Further, the grinding step is followed by a coating step: coating the paste on non-woven fabric, drying under far infrared ray condition with wavelength of 0.72-1000 μm, and sterilizing.

Compared with the prior art, the invention has the beneficial effects that:

1. the preservative-free facial moisturizing composition disclosed by the invention is not added with a preservative, the algal polysaccharide has antibacterial activity, maintains the activity of composition components, is especially suitable for sensitive skin, has hydrolyzed collagen and a humectant, has high moisturizing property, can supplement the elasticity of the skin, maintains the activity of the skin, and can control oil by using plant modified starch;

2. the facial moisturizing composition without the preservative can be applied as a face cream or a facial mask, and is unlimited in use;

3. the preparation method of the facial moisturizing composition without the preservative is simple and rapid, and can be used for batch production.

Detailed Description

The invention will be further described with reference to specific embodiments:

examples 1 to 3:

the preservative-free facial moisturizing compositions of examples 1-3 included the effective components in parts by weight as shown in table 1:

TABLE 1 component quantity parameters for examples 1-3

The method of making examples 1-3, comprising:

a material mixing step: adding the effective components into a dry material mixer for mixing, and then adding distilled water with the temperature of 40-60 ℃ to obtain mixed slurry;

coating: coating the paste on non-woven fabric, and drying under the condition of far infrared ray with wavelength of 0.72-1000 μm;

and (3) sterilization: drying, sterilizing at high temperature to obtain the facial moisturizing composition without preservative.

When the non-woven fabric is used as a carrier, the non-woven fabric can be used as a covering type facial mask for applying a face, and also can be used as a wet tissue for wiping the face, the non-woven fabric is not used as the carrier, the non-woven fabric is directly used as a paste for thinly coating the whole face, or the non-woven fabric is used for thickly coating the face for 10-15min, and then the excessive composition is wiped and lightly tapped for.

The moisturizing effect of examples 1-3 was tested:

the working principle is that the capacitor is used as an instrument probe, and as water is a substance with the largest dielectric constant on the skin, when the moisture content of the skin changes, the capacitance value of the skin also changes, so that the moisture content on the surface of the skin can be analyzed by measuring the capacitance value of the skin. A commonly used instrument is Corneometer CM 825. The moisture-retaining efficacy of the skin care product is evaluated by measuring the change of the water content of the stratum corneum by measuring the change of the capacitance of the stratum corneum of the skin before and after the product is used. The method quantifies the moisture content of the stratum corneum of the skin, can sensitively reflect the change of the moisture content of the skin, and has good reproducibility.

The experimental method comprises the following steps: 50 healthy men and 50 healthy women were used as test subjects, and 3X 3cm was drawn on the left and right cheeks of the test subjects²The water content of each test part in the square test area with the size is calculated by coating the left cheek with the sample 1-3 respectively as a test area, taking the corresponding symmetrical area of the right cheek as a blank control, testing and detecting the water content of each test part by using a Corneometer CM825, repeating the test for 5 times respectively to obtain an average value, and calculating the water content by using the following formula.

Water content ═ (test value-blank value)/blank value × 100%

The results are shown in table 2:

table 2 examples 1-3 moisture content test results

Time of day	Example 1	Example 2	Example 3
				1h	70％	70％	70％
2h	68％	64％	60％
				4h	65％	53％	58％
6h	60％	49％	52％
				8h	52％	41％	49％

As can be seen from Table 2 above, the moisturizing effect of the compositions of examples 1-3 was relatively stable in terms of moisturizing, while the use effect of the composition of example 1 was the best.

Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
