Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a cosmetic composition for moisturizing skin and a preparation method thereof.
Background
Skin dryness is a problem that people often encounter in daily life. Reasons for dry skin include: (1) the physiological requirements of the human body, the water in the human body is consumed; (2) the air humidity is low, and the moisture of the skin is lost due to the dryness of the surrounding environment; (3) the stratum corneum of the skin loses function, the water loss is serious, the water channel between the epidermis layer and the dermis layer is not smooth, and the supplement is slow.
The moisture content of the human skin stratum corneum is about 15-30%, and if the stratum corneum becomes thin, the barrier function is reduced; if the water passage is not open, the moisture in the dermis cannot be transferred to the stratum corneum in time. If the barrier function of the stratum corneum is abnormal, the problems of dry skin, itching, easy allergy, easy skin aging, easy wrinkle and the like can be caused.
The existing moisturizing method is mainly used for exogenously supplementing skin moisture, and although the existing moisturizing method has a certain moisturizing effect, the existing moisturizing method cannot effectively improve the dry skin condition.
Patent document CN 104940047B discloses a cosmetic composition for moisturizing and a preparation method thereof, wherein macromolecular sodium hyaluronate forms a protective film to play a barrier role. In the moisturizing cosmetic composition of the patent, two components of alphos water and erythritol are used, and after reaching a target area, the alphos water and erythritol are continuously replenished with water; aquaporins in the skin exert a transport effect and improve the efficacy of moisturizing. However, this method of replenishing water has a disadvantage that it is not effective for filling up the water gap because it is simple to form a moisturizing film on the skin surface layer using a water-soluble polysaccharide.

Firstly, hand moisturizing effect test:
the sample size of this test was 900 persons, and the cosmetic compositions of examples 1 to 3 of the present invention and comparative examples 1 to 3 were used, respectively. The test site is in cities such as Beijing, Xian, Tianjin and the like, and the time is 9-11 months in 2018; applied to the left and right hands 3 times daily for 1 month. The moisturizing effect of the skin was evaluated after the end of use.
The test methods are shown in table 1 below.
TABLE 1
Secondly, safety testing:
in addition to moisturizing effects, safety is also a primary consideration of cosmetics. Accordingly, the applicant conducted a safety test on the cosmetic composition of the present invention.
250 volunteers were summoned and tested on the inside of the left and right arm, applying 0.5g of the product of the invention on the inside of the left arm each time, 2 times per day, and recording the skin reactions after 24 hours, 36 hours, 72 hours.
The results show that: after the cosmetic provided by the invention is applied for 24 hours, 36 hours and 72 hours, no skin redness or allergy phenomena such as erythema and the like appear, and the moisturizing cosmetic composition provided by the invention is safe.
Thirdly, testing the face moisturizing effect:
the sample size of this test was 600 persons, and the cosmetic compositions of examples 1 to 3 of the present invention and comparative examples 1 to 3 were used, respectively. The test site is in cities such as Beijing, Xian, Tianjin and the like, and the time is 9-11 months in 2018; applied to face 2 times each day (1 time each in the morning and noon) for 1 month. The moisturizing effect of the facial skin was evaluated after the end of the use.
The test methods are shown in table 2 below.
TABLE 2
As is clear from tables 1 and 2, the cosmetic of the present invention has excellent moisturizing ability and can effectively supplement moisture required for the skin. Meanwhile, it can be seen from the data of comparative examples 1 to 3 that the moisturizing effect of the cosmetic composition without tamarind seed polysaccharide and/or hydrogenated lecithin is not significant, and even the moisturizing effect of the skin is not felt by the experimenter. In comparative example 2 and comparative example 3, although the amount of humectant glycerin was increased, the improvement of the quick moisturizing effect was not significant. The main reason is that the invention utilizes the amphiphilic structure of the hydrogenated lecithin to combine the water-soluble acid soybean seed polysaccharide with three oil-soluble plant-derived oils (European cowberry seed oil, Paeonia japonica seed oil and meadowfoam seed oil) to construct a cutin barrier layer of the skin, so that water can easily pass through the cutin barrier layer, thereby moisturizing and nourishing the skin and immediately and remarkably improving the dry state of the skin due to lack of water. If the synergy of both tamarind seed polysaccharide and hydrogenated lecithin is absent, it is difficult to obtain the intended moisturizing effect. Experiments prove that the moisturizing cream has good moisturizing effect and can quickly supplement the water missing from the skin.
