Description
Technical Field
The invention belongs to the field of cosmetics, and relates to a thickening composition of cocoyl alanine salt and application thereof.
Background
Amino acid surfactants are gradually used in daily chemical products because of their advantages of being mild, skin friendly, abundant in foam, easily degradable, etc. Among them, personal cleansing products such as shampoo and the like are generally thickened to various degrees in order to facilitate daily use and to ensure texture of the product. However, the amino acid surfactant as a main surfactant is easy to cause viscosity which cannot reach normal use viscosity, even can only be similar to the viscosity of water, and is difficult to be used in specific scenes such as shampoo, facial cleanser and the like. The amino acid surfactant has a self-thickening function, so that in many daily chemical formulas, the amino acid self-thickening agent is increasingly adopted, and has a self-thickening function and mild surface activity.
However, for personal cleansing products, amino acid surfactants have the problem of being difficult or even impossible to thicken; at present, various manufacturers usually add a thickener of a high molecular polymer. This, in turn, causes the following problems: 1) jelly-like at low temperature; 2) the color change phenomenon is easy to occur at high temperature; 3) foaming of the amino acid type surfactant is suppressed; 4) particularly, the skin feel is influenced by the polymer raw materials during cleaning, and the specific manifestations are stickiness, unclean cleaning and strong residual feel; 5) the price of the high polymer raw material is not so high that the formula cost space is occupied.
CN201810800313.3 discloses an amino acid self-thickening system, which contains sodium lauroyl sarcosinate, alkyl glycoside and cocamidopropyl amine oxide; the patent shows that the system has excellent thickening performance; however, the stability of the system is not high, and the jelly phenomenon is easy to occur at low temperature, so that the use effect at low temperature is influenced.

Example 1 composition containing Cocosylalanine TEA salt
The formulation of the composition is shown in table 1.
TABLE 1 composition containing the TEA salt of cocoyl alanine and viscosity test thereof
The experimental method comprises the following steps: (1) accurately weighing cocamidopropyl betaine, cocamidopropyl hydroxysultaine, cocamidomethyl MEA, cocamidoMEA, cocamidoalanine TEA salt, sodium chloride, deionized water and a proper amount of citric acid into a reaction kettle, heating and keeping the temperature at 80-85 ℃, and uniformly stirring;
(2) supplementing deionized water to 100% of the total mass percent, and uniformly stirring again; (3) taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
As shown in table 1 and fig. 1, the results of the experiments show that the thickening effects of cocamidopropyl betaine, cocamidopropyl hydroxysultaine, cocamidomethyl MEA, cocamidomea, and sodium chloride on the TEA salt of cocoyl alanine are greatly different at different ratios; the proportion of each component in the thickening composition closely influences the viscosity of the system, and most of the systems in multiple proportions show excellent thickening performance on the cocoyl alanine TEA salt; especially, the compositions 4 to 8 are excellent in the effect.
And compositions 16-19, in which case: wherein the amount of CAB in composition 16 was below the specified range (single comparative experiment for composition 3); the level of CHSD in composition 17 was below the specified range (single comparative experiment for composition 9); the CMMEA content of composition 18 was below the specified range (single comparative experiment for composition 12); the CMEA content of composition 19 was below the specified range (single comparative experiment for composition 15); this results in a composition with a very low viscosity, i.e. a poor thickening effect on the cocoyl alanine TEA salt. In addition, if the content of each component in the composition is too high, the indexes such as transparency, foam quantity, greasy feeling, easy washing ability and stability of the system are deteriorated to some extent, which is contrary to the object of the present invention.
Test example 1
The formulation of the composition containing the TEA salt of cocoyl alanine and the results of the viscosity test are shown in table 2, and the inorganic salts are calcium chloride, potassium chloride and magnesium sulfate, respectively.
TABLE 2
The composition was prepared as in example 1, except that the formulation was different. From the results, it can be seen that: when the thickening composition is intact, excellent thickening results can be achieved by replacing some of the different inorganic salts.
Comparative example 1
This comparative example is intended to explore the thickening effect of any of the thickening compositions (containing cocamidopropyl betaine, cocamidopropyl hydroxysultaine, cocamidomethyl MEA, cocamide MEA, sodium chloride) on the cocoyl alanine TEA salt when added alone.
The formulation of each composition is shown in table 3.
TABLE 3 thickening Effect of ingredients in thickening compositions on the Cocoyl alanine TEA salt when added alone
The experimental method comprises the following steps: (1) accurately weighing one component of thickening composition (containing cocamidopropyl betaine, cocamidopropyl hydroxysulfobetaine, cocamidomethyl MEA, cocamidoMEA, and sodium chloride), cocamido alanine TEA salt, deionized water, and appropriate amount of citric acid in a reaction kettle, heating and maintaining at 80-85 deg.C, and stirring uniformly;
(2) supplementing deionized water to 100% of the total mass percent, and uniformly stirring again; (3) taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
The results are shown in table 3, and it can be seen from the experimental results that neither ingredient of the thickening composition alone has a good thickening effect on the cocoyl alanine TEA salt.
Comparative example 2
This comparative example is intended to explore the thickening effect on the cocoyl alanine TEA salt after removal of any of the ingredients in the thickening composition and to compare it with the thickening effect of the complete thickening composition on the cocoyl alanine TEA salt.
The formulation of the composition is shown in table 4.
TABLE 4 viscosity test results after rejection of any of the ingredients in the composition containing the TEA salt of cocoyl alanine
The experimental method comprises the following steps: (1) accurately weighing the rest components of the thickening composition, which are removed from a single component, cocoyl alanine TEA salt, deionized water and a proper amount of citric acid in a reaction kettle, heating and keeping the temperature at 80-85 ℃, and uniformly stirring; (2) supplementing deionized water to 100% of the total mass percent, and uniformly stirring again; (3) taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
The results are shown in table 4 and fig. 2, and it can be seen from the experimental results that the thickening effect of the thickening composition on the cocoyl alanine TEA salt is not good after removing any component; the thickening amplitude of the complete thickening composition on the cocoyl alanine TEA salt can be greatly improved compared with the thickening amplitude of the cocoyl alanine TEA salt; therefore, any component in the thickening composition is indispensable, otherwise, the thickening effect is greatly reduced, and the characteristic that various components in the composition are thickened synergistically and are indispensable is reflected.
Example 2 composition containing sodium Cocoacylalaninate
This example is intended to investigate the thickening effect of cocamidopropyl betaine, cocamidopropyl hydroxysultaine, cocamidomethyl MEA, cocamide MEA, sodium chloride on sodium cocoyl alanine at different ratios.
The formulation of the composition is shown in table 5.
Table 5 sodium cocoyl alanine containing compositions and viscosity testing thereof
The experimental method comprises the following steps: (1) the cocoamidopropyl betaine, the cocoamidopropyl hydroxy sulfobetaine, the cocoamidomethyl MEA, the cocoamidoMEA, the sodium cocoyl alanine, the sodium chloride, the deionized water and a proper amount of citric acid are accurately weighed and put into a reaction kettle, the temperature is increased and kept between 80 ℃ and 85 ℃, and the stirring is uniform. (2) And supplementing the deionized water to 100 percent of the total mass percent, and uniformly stirring again. (3) Taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
The results are shown in table 5 and fig. 3, and it can be seen from the experimental results that the ratio of each component in the thickening composition of the present invention closely affects the viscosity of the system; by adjusting the proportion of the components, the composition with excellent thickening performance on sodium cocoyl alanine can be obtained.
Such as compositions 47-50 (single variable comparisons based on composition 46), the thickening effect on sodium cocoyl alanine is poor at lower levels of the components in the composition. In addition, if the content of each component in the composition is too high, the indexes such as transparency, foam quantity, greasy feeling, easy washing ability and stability of the system are deteriorated to some extent, which is contrary to the object of the present invention.
Test example 2
The formulation of the composition containing sodium cocoyl alanine and the results of the viscosity test are shown in table 6, and the inorganic salts are calcium chloride and potassium chloride, respectively.
TABLE 6
The composition was prepared as in example 2, except that the formulation was different.
From the results, it can be seen that: when the thickening composition is intact, excellent thickening results can be achieved by replacing some of the different inorganic salts.
Comparative example 3
This comparative example is intended to explore the thickening effect of cocoamidopropyl betaine, cocoamidopropyl hydroxysultaine, cocoamidomethyl MEA, cocoamidomea, sodium chloride on sodium cocoyl alanine when added alone in the thickening composition.
The formulation of the composition is shown in table 7.
TABLE 7 thickening Effect of ingredients in thickening compositions on sodium cocoyl alanine when added alone
The experimental method comprises the following steps: (1) accurately weighing one component of the thickening composition, sodium cocoamide alanine, deionized water and citric acid in a reaction kettle, heating and keeping the temperature at 80-85 ℃, and uniformly stirring. (2) And supplementing the deionized water to 100 percent of the total mass percent, and uniformly stirring again. (3) Taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
As shown in table 5, it can be seen from the experimental results that neither ingredient of the thickening composition used alone has a good thickening effect on sodium cocoamidoalaninate.
Comparative example 4
This comparative example is intended to investigate the thickening effect on sodium cocoyl alanine after removal of any of the ingredients of the thickening composition and to compare it with the thickening effect of the complete thickening composition on sodium cocoyl alanine.
The formulation of the composition is shown in table 6.
TABLE 6 thickening Effect on sodium Cocoacylalaninate by elimination of any of the ingredients in the thickening composition
The experimental method comprises the following steps: (1) accurately weighing the rest components of the thickening composition, sodium cocoyl alanine, deionized water and a proper amount of citric acid in a reaction kettle after single component of the thickening composition is removed, heating and keeping the temperature at 80-85 ℃, and uniformly stirring. (2) And supplementing the deionized water to 100 percent of the total mass percent, and uniformly stirring again. (3) Taking out the reaction kettle, sealing, putting into a thermostat at 25 ℃ for 24h, and then measuring the viscosity.
As shown in table 6 and fig. 4, it can be seen from the experimental results that the thickening composition does not have good thickening effect on sodium cocoyl alaninate after any component is removed; the thickening amplitude of the complete thickening composition on sodium cocoamide alanine can be greatly improved compared with the thickening amplitude of the complete thickening composition on sodium cocoamide alanine. It is proved that any component in the thickening composition is indispensable again, otherwise the thickening effect is greatly reduced, and the characteristic that various components in the composition are thickened synergistically and are indispensable is reflected.
