Embodiment 1

[0031] Moisturizers are substances with strong hygroscopicity, commonly used are glycerin, propylene glycol, sorbitol, etc.; the other is hygroscopic ingredients naturally present in the stratum corneum of the skin, such as urea, emulsion, amino acid, sodium pyrrolidone carboxylate, etc.; Another type of moisturizer with the ability to bind water is collagen and moisturizing anti-aging complexes present in the dermis. Due to the limitation of molecular weight, the moisturizing performance of collagen is also limited. Collagen is usually not used as a moisturizer in cosmetics.

[0032] a) Determination method of hygroscopicity

[0033] Place saturated potassium carbonate solution and saturated ammonium sulfate solution in two desiccators respectively, store at 20°C

[0034] In a constant temperature oven, the environment with relative humidity (R.H.) of 43% and 81% is made for the determination of moisture absorption. Accurately weigh the sample, put it into two desiccators, w...

Embodiment 2

[0048] Various humectants were added to the same basic formula, and their moisture retention and hygroscopicity were tested at different humidity levels.

[0049] Table 1 Comparison of hygroscopicity and moisture retention of three humectants in 40 hours

[0050]

[0051] Table 2 Comparison of hygroscopicity and moisture retention of three humectants in 48 hours

[0052]

[0053] Table 3 Comparison of hygroscopicity and moisturizing properties of 9 common humectants

[0054]

[0055] Such as figure 1 As shown in Table 1, Table 2, and Table 3, ethylene glycol, 1,2 propylene glycol, and glycerin have good hygroscopicity but poor moisturizing performance under low humidity; sorbitol has good water retention effect, but Hygroscopicity is not ideal, sodium pyrrolidone carboxylate is too hygroscopic, these humectants will absorb moisture from the air in a high humidity environment, but will absorb moisture from the skin when the air humidity is low (especially in cold and...

Embodiment 3

[0057] Such as figure 2 and image 3 As shown, the emulsion containing 2% moisturizing and anti-aging complex compared with 2% ceramide + 3% NMF-50 emulsion in 30 female subjects

[0058] Compared with 2% ceramide + 3% NMF-50 emulsion, it has a longer-lasting moisturizing effect

[0059] Ten female subjects applied a lotion containing 2% Moisture Anti-Aging Complex for 4 weeks to enhance the skin's: moisture content, firmness, elasticity, smoothness.

[0060] Because β-glucan can promote the proliferation of Langerhans cells and thus enhance skin immunity, clinical studies have also shown that β-glucan also has significant anti-inflammatory and anti-allergic activities, and can help the skin resist exogenous Sexual mechanical and chemical stimuli.

Abstract

The invention relates to the cosmetic field, particularly relating to a moisture retention and anti-aging compound with clinic or biophysical properties used in cosmetics. The compound comprises the following components, by weight, 0.1-0.8% of low molecular weight hyaluronic acid, 0.1-0.2 % of common molecular weight hyaluronic acid, 1-5% of oat glucan, 3-5% of D-panthenol, 0.3-0.5% of phenoxyethanol and 89.5-95.3% of deionized water. Cosmetics with the moisture retention and anti-aging compound provided in the invention can improve pathological changes caused by aging, long-term solarization and improper usage of household cosmetics, changed skin appearances and functions caused by malnutrition and the like with good cooperation effect, optimize skin moisture retention restoration components, and substitute moisture absorption components which naturally exist in the skin stratum corneum.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a moisturizing and anti-aging complex for cosmetics with clinical / biophysical properties. Background technique [0002] As a result of aging and chronic exposure to adverse environmental factors, the appearance, physical properties, and physiological functions of the skin change in various ways, the most notable changes include increased fine lines and wrinkles, loss of elasticity, increased sagging, and loss of firmness , lack of uniformity (tension) of color, rough surface texture, and patchy pigmentation. Less obvious but measurable changes that occur as skin ages or undergoes long-term environmental damage include a general decrease in cell and tissue viability, decreased cell replication, decreased skin blood flow, decreased moisture, accumulation of structural and functional errors, and skin Decreased ability to rebuild and repair itself. Many of the changes in appearance and fun...
