Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a thickening and foaming composition and application thereof in the preparation of cleaning products. Background Art

[0002] Sodium trideceth sulfate is an anionic surfactant commonly used as a foaming agent in shampoo, shower gel, and other skincare products. Due to its high charge density, using sodium trideceth sulfate as a foaming agent in skincare products can be difficult to thicken, requiring the addition of large amounts of auxiliary thickeners or high-concentration electrolytes. These additions can easily affect the stability and mildness of the products.

[0003] Traditionally, sodium chloride is added to thicken cleaning products, but its thickening effect is limited and excessive use can be very irritating. Summary of the Invention

[0004] In response to the above-mentioned deficiencies in the prior art, the present invention provides a thickening and foaming composition. By compounding sodium tridecyl polyether sulfate and vegetable oil, the molecular structures of the two are mutually attracted, thereby improving the properties of the micelles formed by sodium tridecyl polyether sulfate, allowing the vegetable oil to be better adsorbed on the micelles, greatly improving the viscosity of the washing and care products in which sodium tridecyl polyether sulfate is the main surfactant, and solving the thickening problem of the washing and care products in which sodium tridecyl polyether sulfate is the main surfactant; at the same time, the addition of sodium tridecyl polyether sulfate solves the serious defoaming problem of vegetable oils used in washing and care products, and can obtain a better rinsing feeling.

[0005] The present invention aims to provide a thickening and foaming composition, comprising sodium tridecyl alcohol polyether sulfate and vegetable oil.

[0006] In some embodiments of the present invention, the mass ratio of the sodium trideceth sulfate to the vegetable oil is 0.8-2.4:0.8-2.4.

[0007] In some embodiments of the present invention, the mass ratio of the sodium trideceth sulfate to the vegetable oil is 1-2:1-2.

[0008] In some embodiments of the present invention, the plant oil comprises at least one of camellia seed oil, olive oil, shea butter, grape seed oil, jojoba oil, and coconut oil.

[0009] In some embodiments of the present invention, the thickening and foaming composition further comprises cocamide methyl MEA and xanthan gum.

[0010] In some embodiments of the present invention, the mass ratio of sodium trideceth sulfate, cocamide methyl MEA, and xanthan gum is 22:1-5:0.02-0.5.

[0011] Another object of the present invention is to provide use of the thickening foaming composition as a thickener.

[0012] Another object of the present invention is to provide use of the thickening and foaming composition in the preparation of cleaning products.

[0013] In some embodiments of the present invention, the amount of the thickening and foaming composition is 22 to 44% of the washing and care product by mass percentage.

[0014] Another object of the present invention is to provide a cleaning product containing an effective amount of the thickening and foaming composition.

[0015] In some embodiments of the present invention, the amount of the thickening and foaming composition is 22 to 44% of the washing and care product by mass percentage.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention compounds sodium tridecyl polyether sulfate and vegetable oil, and the molecular structures of the two are mutually attracted, thereby improving the properties of the micelles formed by sodium tridecyl polyether sulfate, allowing the vegetable oil to be better adsorbed on the micelles, greatly improving the viscosity of the washing and care products with sodium tridecyl polyether sulfate as the main surfactant, and solving the thickening problem of the washing and care products with sodium tridecyl polyether sulfate as the main surfactant.

[0018] (2) Although plant oils have excellent moisturizing and repairing effects, their hydrophobicity can destroy the micellar structure of surfactants, causing the foam in the cleaning products to collapse quickly, affecting the user experience. To reduce the defoaming problem of plant oils, the existing technology usually requires sacrificing the amount of plant oil added or adding silicone defoaming inhibitors, which not only leads to a decrease in product efficacy but also poses environmental problems. The present invention combines sodium tridecyl alcohol polyether sulfate with plant oils, and the molecular structures of the two interact with each other, so that the plant oils do not destroy the micellar structure of sodium tridecyl alcohol polyether sulfate, achieving a good foaming effect.

[0055] Table 9. Performance test results of body wash.

[0056]

[0057]

[0058] According to Table 9, by comparing Example 49 with Comparative Examples 11-12, Example 53 with Comparative Examples 11 and 13, Example 57 with Comparative Examples 11 and 14, Example 61 with Comparative Examples 11 and 15, Example 65 with Comparative Examples 11 and 16, and Example 69 with Comparative Examples 11 and 17, it can be seen that the present invention, by compounding sodium tridecyl alcohol polyether sulfate and vegetable oil, the molecular structures of the two mutually attract each other, playing a synergistic role in improving the viscosity of the care product. The vegetable oil improves the properties of the micelles formed by sodium tridecyl alcohol polyether sulfate, allowing the vegetable oil to be better adsorbed on the micelles, greatly improving the viscosity of the care product in which sodium tridecyl alcohol polyether sulfate is the main surfactant, and solving the thickening problem of the care product in which sodium tridecyl alcohol polyether sulfate is the main surfactant.

[0059] By comparing Examples 47 to 50 with Comparative Example 25, it can be seen that the present invention compounds sodium tridecyl polyether sulfate and vegetable oil, and the molecular structures of the two are mutually attracted, so that the vegetable oil does not destroy the micelle structure of sodium tridecyl polyether sulfate, thereby achieving a good foaming effect.

[0060] Investigate the role of cocamidomethyl MEA and xanthan gum in cleaning products:

[0061] According to the mass percentage of the thickening foaming composition in the washing and care products in Table 4, the thickening foaming composition raw materials of Examples 45 to 46 were used to prepare shower gels, as shown in Table 10.

[0066] Table 11. Shower gel ingredients and production process.

[0067]

[0068]

[0069] According to the mass percentage of the thickening foaming composition in the washing and care products in Table 4, the raw materials of the thickening foaming composition of Comparative Example 23 were used to prepare shower gels, as shown in Table 12.

[0073] Table 13. Shower gel ingredients and production process.

[0074]

[0075] The viscosity of the shower gels of Examples 71 to 72 and Comparative Examples 35 to 37 prepared in Tables 10 to 13 was tested respectively. The results are shown in Table 14.

[0076] Table 14. Performance test results of body wash.

[0077] sample Viscosity (mPa·s) (4#, 3R) Example 71 16783 Example 72 16548 Comparative Example 35 10457 Comparative Example 36 253 Comparative Example 37 798

[0078] According to Example 47 in Table 9 and Table 14, and by comparing Comparative Examples 36-37 in Table 14, it can be seen that the addition of xanthan gum reduces the viscosity of the cleaning product. Comparing Example 47 in Table 9 with Comparative Examples 35-36, it can be seen that the addition of xanthan gum and cocamidomethyl MEA to the cleaning product increases the viscosity of the cleaning product compared to the addition of cocamidomethyl MEA alone. This shows that xanthan gum can promote the increase in the viscosity of the cleaning product caused by cocamidomethyl MEA.
