Description

Seaweed moisturizing mask liquid and preparation method thereof

Technical Field

The invention relates to the technical field of daily cosmetics, in particular to a moisturizing facial mask liquid containing haematococcus pluvialis extract and a facial mask prepared from the moisturizing facial mask liquid.

Background

The skin is distributed throughout the body and is an important component of the human body. The skin is used as an important barrier of human body, and can prevent the invasion of external physical and chemical factors and the loss of water and nutrient substances in the body through the epidermis. A layer of film can be naturally formed on the surface of the skin to protect the skin and keep the skin smooth and flexible. However, with seasonal changes, aging, and personal skin problems, the skin tends to be deficient in water, which causes various problems. The key part of the skin barrier function is the stratum corneum, generally speaking, the water content of the stratum corneum of the skin is 20% -35%, and the skin is smooth, fine and glossy and is not easy to wrinkle and pigmentation. If the water content of the stratum corneum of the skin is less than 10%, the skin becomes dry, rough, dull in color, mottled, and the like. Therefore, the key to skin care is to maintain the moisture content of the skin, reduce the loss of moisture of the skin, and maintain the water-oil balance of the skin, thereby improving various problems of the skin.

With the concern of skin care, people have higher requirements on improving skin quality from the initial protection of skin from dryness to the present, so that the skin looks more moist and healthy, and is more and more attractive. The basis of improving the skin quality is to replenish water to the skin, so a large amount of moisturizing skin care products are produced at the same time. At present, the moisturizing components in moisturizing skin care products mainly comprise sodium hyaluronate, betaine, chitosan, polyalcohol, plant extract and the like, but the effect is not ideal, some moisturizing products only moisturize the surface of skin, and the skin can be dried again in a short time after the moisturizing skin care products are used; some moisturizing products have good moisturizing effect, but the absorption speed is slow, and the skin feels sticky and airtight after the product is used; some moisturizing products have good moisturizing effect and high absorption speed, but the skin is astringent and not smooth and fine enough after the moisturizing products are used. In recent years, with the development of science, many plant active ingredients with moisturizing and antioxidant effects in the nature are discovered and widely applied to the fields of cosmetics and skin care products. The continuous development of new functional cosmetics to achieve longer moisturizing effect has become an important research topic in the field.

The reasons for water shortage of the skin are two, one is water and oil imbalance of the skin, if oily skin is lack of water, the skin is dry, and if dry skin is lack of oil and fat, water locking cannot be achieved, the skin is dry, so that water replenishing and water and oil balance adjusting are the main functions of the moisturizing cosmetic at present, meanwhile, the other reason for water shortage of the skin is an external environment, such as long-time air conditioning environment, long-time sunlight and ultraviolet irradiation and skin shortage caused by a severe environment, although damage to the skin can be relieved by a water replenishing method due to the water shortage of the skin caused by the reasons, water replenishing is needed in time and is continuous, and water replenishing cannot be achieved in time due to objective reasons in many times, great damage to the skin can be caused, and therefore the moisturizing product for protecting the skin from external stimulation can better and more comprehensively achieve moisturizing and skin protection. Current moisturizing hydrating moisturizing products lack this concern.

Haematococcus pluvialis belongs to the order Volvocales, the family Haematococcus. Haematococcus pluvialis is a microorganism with the highest astaxanthin content in nature, and is the best natural source of astaxanthin. Haematococcus pluvialis contains 1.5% to 3.0% astaxanthin and is considered to be a "concentrate" of natural astaxanthin. Astaxanthin is one of the strongest natural antioxidants in the world, can effectively remove oxygen free radicals in cells, enhance the regeneration capacity of the cells, maintain the balance of organisms, reduce the accumulation of aged cells, and protect the health of the cells and DNA from inside to outside, thereby protecting the health of skin. The haematococcus pluvialis extract rich in astaxanthin can permeate into each skin cell, rebuild collagen and protein matrix, remold skin elasticity, strengthen the skin 'heat preservation barrier' and fully keep skin moisture, thereby playing the effects of moisturizing and resisting wrinkles.

Tetrahydromethylpyrimidine carboxylic acid, also known as Izodiacin, having the England name Ectoin, is derived from highly halophilic bacteria (Halomonas Elongata), which are found in Egyptian desert salt lakes, and therefore this component is also referred to as "halotolerant extract". Ectoin protects halophilic bacteria from damage under extreme conditions of high salt, high temperature, high ultraviolet radiation. Ectoin is an amino acid derivative, belongs to the class of extreme pressure protection factors, and can protect extremophile from extreme environments, such as salt lakes, hot springs, deserts, craters and the like. Ection can construct a strong protective layer consisting of water molecules in the skin, protect the skin from being damaged by internal and external stimulation factors, and prevent skin aging and cell damage.

The mechanism of Ectoin protection: ectoin is a potent Kosmotropic ordering substance, and small amino acid derivatives bind surrounding water molecules to form "ectoin water complexes". This layer of complex then wraps around cells, enzymes, proteins and other biomolecules, forming a hydrated shell with protective, nourishing and stabilizing effects. Due to the existence of the protective shell, the damage of the skin to stress factors such as ultraviolet radiation, pollution particles, cold and hot, dryness and the like can be reduced.

The saccharide isomer is called "water-locking magnetite", which is a natural humectant extracted from a cane sugar complex to assist water in combining with keratin in the horny layer to achieve a moisturizing effect. The water-locking magnet is used as a good water-retaining agent and emollient, and has the effects of repairing epidermal cells and improving the water replenishing capacity of skin. The isomerized D-glucan manufactured by the biochemical technology has a composition structure similar to the human stratum corneum, can be combined with epsilon-amino acid functional groups when being used on the skin, is firmly combined like a magnet, and can maintain the water magnetic field capability of the skin for a long time.

Sodium hyaluronate, also known as sodium hyaluronate, has a basic structure of large polysaccharides consisting of two disaccharide units, D-glucuronic acid and N-acetylglucosamine. Unlike other mucopolysaccharides, it contains no sulfur. Its hyaluronic molecule can carry over 500 times of water, is the best moisture-keeping component recognized at present, and is widely applied to maintenance products and cosmetics.

Oat glucan is a non-starch polysaccharide existing in cell walls of oat endosperm and aleurone layer, can improve skin texture and skin elasticity, and has excellent moisturizing and repairing effects.

The haematococcus pluvialis extract, the saccharide isomerate, the tetrahydro-methyl pyrimidine carboxylic acid, the sodium hyaluronate and the oat glucan can generate a synergistic effect, can enhance a moisturizing effect, continuously lock water, thin lines can be desalted, no sticky feeling exists, and meanwhile, the addition of the ectoin (tetrahydro-methyl pyrimidine carboxylic acid) can better protect skin cells, so that the skin is prevented from being stimulated by the outside, the moisture is relieved, and the damage of the outside stimulation to the skin is prevented.

2. Skin care test Long term Effect

125 female volunteers aged 18-45 years old were randomly selected for testing, and were randomly divided into 5 groups of 25 persons each, and volunteers signed volunteers before testing. After cleaning the arm, the volunteer was positioned after balancing the environment at constant temperature and humidity (room temperature 22-25 deg.C and humidity 40-60%) for 30 minutes, and skin conditions (including moisture content, elasticity, and fine lines) were measured with a skin tester and marked at the test site. The samples of examples 1-5 of the present invention were applied to 5 groups of volunteers at the marked locations for one month consecutively. After one month, the skin condition of the marked position is tested, the change conditions of the parameters before and after the mark position are compared, and the using effect of the skin of the marked position after the mask sample is used for a long time is evaluated. The results are shown in Table 3.

TABLE 3 Long-term use of seaweed moisturizing mask liquid

Effect	Example 1	Example 2	Example 3	Example 4	Example 5
						Humidity increase	21	22	23	24	25
Increase of elasticity	18	20	21	20	22
						Reduction of fine lines	15	17	19	20	22

Test results show that the mask has the efficacy of long-acting moisture retention, can increase the water content and elasticity of skin, and can effectively fade fine wrinkles. The mask sample of example 5 had better results than the other samples.

3. Outdoor testing

150 volunteers aged 18-45 years and engaged in outdoor high-temperature work are selected and randomly divided into 6 groups of 25 persons, and the volunteers are signed with volunteer books before testing. The test site was the skin of the volunteer exposed. The skin is positioned after the environment with constant temperature and humidity (indoor temperature is 22-25 ℃, humidity is 40-60%) is balanced for 30 minutes, and the skin moisture content is measured by a skin tester. The samples of examples 1-5 of the present invention were applied to three groups of volunteers in the respective locations, and 20 minutes after application, the moisture content of the skin at the marked locations was tested, and group 6 volunteers were treated with other moisturizing products. Then 150 volunteers work outdoors at high temperature, after one hour, the moisture content of the skin at the marked position is tested, the moisture content of the skin is measured according to the average value of the whole group, the unit of the moisture content of the skin is au, and the skin protection effect of the mask sample is evaluated by comparing the change conditions before and after the skin moisture content is measured. The results are shown in Table 4.
