Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a composition for preparing an emulsified product with a high cream-setting point and an application thereof. Background Art

[0002] Emulsified products occupy a huge market in cosmetics, and cream skin care products are an important component of emulsified products. However, existing cream skin care products currently sold in the market still have some problems.

[0003] The problem is that in order to improve stability, cream skin care products often need to add more waxy raw materials and different polymer stabilizers, which is not conducive to the delivery of active ingredients in cream skin care products, and thus affects the overall use effect of cream skin care products. In addition, during use, they feel heavy and greasy.

[0004] In addition, the viscosity and hardness of paste products will change greatly with temperature, and may even cause water and oil separation. Affected by the external environment, emulsified cosmetics containing crystalline ingredients are very likely to produce a granular feel, making the product appearance coarse, and even precipitating crystals that affect product use. The paste-forming temperature during product preparation is generally around 40°C, which is generally low. The low paste-forming temperature causes the product to have greater stability problems when the external temperature is high, and even stratification occurs.

[0005] In summary, a composition for preparing an emulsified product with a high setting point and its application are needed to reduce the use of wax raw materials and polymer stabilizers in the emulsified product, facilitate the delivery of active ingredients, and provide a melting and release feeling when touched.

[0110] The dropping point of the emulsified product with high setting point is tested and the average value is taken. Figure 1 As shown, the dropping point temperature of the emulsified product obtained in this embodiment can reach 72.1°C.

[0111] The dropping point (DP) is defined as the temperature at which the first drop of the molten sample of the substance being measured flows through the 2.8 mm opening of the standard dropping point sample cup when slowly heated. The dropping point is measured using a sample (molten or liquid) with a viscosity low enough to flow through a 2.8 mm diameter opening under high temperature conditions. The dropping point (or softening point) of the present invention is tested using a WQD-360 dropping point instrument ( Figure 1 ).

[0113] The high-setting point emulsified product obtained in this example was subjected to high-temperature (50°C) shearing to detect its rheological properties. First, the shear performance of the product was explored. The shear rate was set from 0.01s -1 Gradually increase to 100s -1 , determine the change of product viscosity with shear rate within this shear change range (such as Figure 3). Obviously, the system has good shear-thinning properties, and the viscosity drops sharply with the increase of shear force. That is, during storage, since the emulsion is not subject to shear, the viscosity is relatively high and has good storage stability; during the application process, due to friction shear, the viscosity of the emulsion decreases, and it is very easy to spread on the skin surface and has a good skin feel. In addition, in a small-amplitude oscillating flow field, γ=10% was set, and the angular frequency ω was changed from 800rad / s-0.1rad / s. The system was frequency scanned to measure the changes in the storage modulus and loss modulus of the product. It shows that the storage modulus is greater than the loss modulus, and the characteristics of the sample are more inclined to elastic solids. This phenomenon reflects that the system structure is still stable at a high temperature of 50°C ( Figure 4 ).

The composition adopts the composition in Example 1.

[0125] The pretreated collagen was prepared by mixing 20 g of collagen, 5 g of chondroitin sulfate and 250 g of water and stirring at a speed of 350 r / min for 90 min.

[0126] A method for preparing an emulsified product with a high setting point, comprising mixing the composition obtained in Example 1 with squalane, isooctyl palmitate, glycerin, and 1,2-hexanediol, and heating until all are dissolved to obtain a phase A material, wherein the heating temperature is 85° C.;

[0127] Under homogenization conditions, 80°C deionized water was slowly added to the phase A material. After emulsification and homogenization for 8 minutes, the mixture was stirred and cooled at room temperature at a stirring speed of 100-300 rpm. During the cooling process, pretreated collagen and p-hydroxyacetophenone were added and stirred to room temperature.

[0128] The volume change rate of the emulsified products obtained in Example 10, Example 11, Comparative Example 1 and Comparative Example 2 after being treated at high temperature of 80°C and low temperature of 5°C was detected, and the material state after high and low temperature cycles (5-80°C×30 times) was observed.

[0129] The volume change rate is Figure 5 As shown, although Comparative Examples 1 and 2 also use the composition obtained in Example 1 and add some raw materials relative to Example 10, the volume change rate of Example 10 is lower than that of Comparative Examples 1 and 2, confirming that the present invention uses pretreated collagen and polyfructose to produce a synergistic effect, and if the two are used alone, performance degradation will occur.

[0130] The volume change rate of Example 11 is lower than that of Example 10 (P < 0.05), which further proves that the pre-treated collagen and polyfructose of the present invention can produce a synergistic effect and effectively improve the stability of the emulsion.

[0131] After the high and low temperature cycles, Example 10 and Example 11 still maintained their original state, but Comparative Example 1 and Comparative Example 2 experienced stratification.

[0132] The collagen and chondroitin sulfate in the emulsified product of the present invention are physically cross-linked to form a macromolecular protein structure; and then compounded with the composition, not only can the composition be effectively promoted to be stably dispersed in oils and polyols, but also has a higher hydrophilicity.

[0133] Since the pretreated collagen has good hydrophilicity, the stability of the emulsion formed by combining with the water phase is further improved.

[0134] After many experiments, it was confirmed that compared with using collagen alone, pre-treated collagen can effectively improve the stability of the emulsion. Even after repeated heating and cooling, no stratification, sedimentation or precipitation will occur. Through further interaction between collagen and polyfructose, the volume change during the paste setting process is small and the thermodynamic stability is good.

[0135] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
