Description

Technical Field

[0001] The invention relates to the field of personal care, in particular to a high-viscosity transparent gel cleaning composition. The cleaning composition has a transparent appearance, high viscosity, good spreadability, no jelly at low temperatures, and good pumping performance. Background Art

[0002] In recent years, with the introduction of the "dual carbon" concept, all walks of life in China have been offering suggestions for energy conservation and emission reduction, hoping to achieve the goal of carbon neutrality as soon as possible. As a booming industry in recent years, leading companies in the daily chemical industry have responded to the call, from raw materials, to semi-finished products, to processes, to packaging, all links are working hard to achieve carbon neutrality. The design of cosmetic formulas runs through the links of raw material selection, formula construction, and production process, so it plays a vital role in the realization of carbon neutrality by daily chemical companies. In order to avoid the inefficient application of raw materials and simplify the production process, the "minimalist formula" came into being and has become a highly respected formula design concept in recent years, that is, using as few raw materials as possible to maximize their role, fundamentally realizing the efficient use of raw materials and reducing unnecessary waste. Viscosity index is one of the important indicators of daily chemical cleaning products. Thickeners, as viscosity regulators of formulas, have little added value except for increasing the viscosity of the system. On the contrary, while adding various thickeners to improve the viscosity of surfactants, it will bring about the following problems: a jelly-like gel-like phenomenon occurs at low temperatures; discoloration occurs easily at high temperatures; the foaming properties of surfactants are suppressed; the skin feel during cleansing is affected by the polymer raw materials, resulting in stickiness, incomplete cleaning, and a strong sense of residue; the high price of polymer raw materials squeezes the cost space of the formula, and a series of other problems.

[0003] Realizing system self-thickening through reasonable matching of surfactants can not only greatly increase the utilization rate of raw materials, but also avoid the various problems mentioned above caused by the use of thickeners. In recent years, amino acid surfactants have been favored because of their mildness and the easy-to-rinse properties of soap bases. However, it cannot be ignored that most of the commercially available products are still ordinary surfactant systems due to the high cost of amino acid formula systems and the alkalinity of soap base formula systems. Discovering self-thickening technology suitable for ordinary surfactant systems and simplifying formulas and processes are also one of the directions that cosmetic formula engineers need to work on to help companies achieve "dual carbon".

[0004] Common surfactant self-thickening systems are anionic surfactants combined with amphoteric surfactants or nonionic surfactants. Although this system can produce high-viscosity products at room temperature, it is easy to produce jelly-like gel when the viscosity exceeds 10000mPa or under low temperature conditions, thus affecting the product's pumping performance, foaming performance and other performance.

[0005] Chinese patent CN 108542796 A discloses an amino acid self-thickening system, which relates to an amino acid self-thickening system containing sodium lauroyl sarcosinate, alkyl glycoside and cocamidopropylamine oxide. Among them, the amount of sodium lauroyl sarcosinate is 4%-8%; the amount of cocamidopropylamine oxide is 8%-12%; the amount of alkyl glycoside is 3%; the total amount of sodium lauroyl sarcosinate and cocamidopropylamine oxide is 16%; the pH value of the system is 5.2-5.8; the solvent is water. The purpose of the present invention is to provide an amino acid self-thickening system that exhibits very excellent thickening performance when the amount of sodium lauroyl sarcosinate and cocamidopropylamine oxide reaches 16% or more of the system weight, and the amount of alkyl glycoside reaches 3% or more.

[0006] European patent EP 105 304A1 discloses a self-thickening dilutable concentrate for hard surface and dishwashing, and introduces a water-dilutable hard surface cleaning concentrate containing at least one fatty alcohol polyether sulfate and at least one betaine or amine oxide, and its use and preparation method, the method comprising diluting the concentrate with water, wherein the weight ratio of the fatty alcohol polyether sulfate to the betaine or amine oxide is between 50:50 and 70:30.

[0007] The present invention unexpectedly found that a high-viscosity transparent gel cleaning composition can be obtained without the need to add additional inorganic salts for thickening, and the composition will not form a jelly-like gel under low temperature conditions.

The samples are observed to see if there are solid particle precipitation, jelly formation, stratification, etc. If the sample is normal and unchanged before and after a certain time within 30 days, it means "passed", the appearance of solid particles means "precipitation", the production of viscoelastic gel that is not easy to flow means "jelly", and the appearance of two layers of liquid above and below means "stratification". The results are shown in the following table.

[0083] Table 1: Stability study of different raw materials

[0084]

[0085]

[0086] Conclusion: The content of sodium laureth sulfate and lauryl hydroxysulfobetaine was fixed, and the proportion of laureth-5 carboxylic acid was adjusted to investigate its effect on the viscosity and stability of the system.

When the addition amount of laureth-5 carboxylic acid is more than 10%, the material is in a gel state, and the gel still has good spreadability and pumping performance at a low temperature of 4°C. However, whether the increase in the viscosity of the system is caused by the increase in the total amount of surfactants needs further study.

[0105] Test Example 2: Stability Test

[0106] After measuring the pH (direct measurement at 25°C) and viscosity (Brookfield 25°C 6# rotor 12 rpm 30s, when the torque is less than 10%, replace with 3# rotor 12 rpm 30s) of Examples 6-14, their stability was investigated.

[0107] The stability evaluation method is as follows: the liquid cleaning compositions prepared in Examples 6-14 are placed in a thermostat at a high temperature (48°C, 25°C, 4°C) for 30 days. The samples are observed to see if there are solid particle precipitation, jelly formation, stratification, etc. If the sample is normal and unchanged before and after a certain time within 30 days, it means "passed", the appearance of solid particles means "precipitation", the production of viscoelastic gel that is not easy to flow means "jelly", and the appearance of two layers of liquid above and below means "stratification". The results are shown in the following table.

[0108] Table 2: Stability study of different raw materials

[0109]

[0110] Conclusion: Examples 6-14 fixed the addition amount of lauryl hydroxysulfobetaine at 2.4%, the total active matter content of the system at 28.4%, and by adjusting the mass ratio of sodium laureth sulfate and laureth-5 carboxylic acid, investigated the effects of different proportions of the two raw materials on the viscosity and stability of the system. According to the viscosity and stability results in the above table, Examples 8, 9, 10, and 11 can produce high-viscosity transparent gel cleaning compositions. That is, at a total active matter content of 28.4%, the amount of amphoteric surfactants was fixed, and the system viscosity was higher when the mass ratio of sodium laureth sulfate and laureth-5 carboxylic acid was between 2:1 and 1:2, and the viscosity decreased when the mass ratio of the two raw materials was greater than or equal to 2:1 and less than or equal to 1:2. It can be seen that the effect of laureth-5 carboxylic acid on viscosity is not a linear relationship.

[0146] After measuring the pH (direct measurement at 25°C) and viscosity (Brookfield 25°C 4# rotor 12 rpm 30s) of Examples 19-28, their stability was investigated.

[0147] The stability evaluation method is as follows: the liquid cleaning compositions prepared in Examples 19-28 are placed in a thermostat at a high temperature (48°C, 25°C, 4°C) and observed for 30 days. The samples are observed to see if there are solid particle precipitation, jelly formation, stratification, etc. If the sample is normal and unchanged before and after a certain time within 30 days, it means "passed", the presence of particles means "precipitation", the production of viscoelastic gel that is not easy to flow means "jelly", and the presence of two layers of liquid above and below means "stratification".

[0148] Table 4: Stability study of different raw materials

[0149]

[0150] Conclusion: In Examples 19-26, the total active matter content is fixed at 20%, the mass ratio of sodium laureth sulfate and laureth-5 carboxylic acid is 3:1, the amount of lauryl hydroxysulfonyl betaine is adjusted, and the viscosity change of the system is observed. It can be seen from the experimental data that when the mass fraction of lauryl hydroxysulfonyl betaine is 5-8, the viscosity of the system is the largest, and a transparent gel-like composition can be obtained, and it still has good spreadability and pumpability at low temperature. Example 27 is a self-thickening system of sodium laureth sulfate and lauryl hydroxysulfonyl betaine, and the system is already jelly-like at room temperature. Example 28 adds 1% laureth-5 carboxylic acid to Example 27, and the system can still maintain a high viscosity, and at the same time has good spreadability at low temperature. It shows that the addition of laureth-5 carboxylic acid is helpful to improve the low-temperature jelly problem of the system.
