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.
