Problems solved by technology

As we all know, nonionic emulsifiers are generally inferior to anionic emulsifiers in their ability to emulsify oils, so the presence of a high proportion of nonionic emulsifiers and alcohol solvents will seriously affect the emulsification ability of anionic emulsifiers and affect the external structural properties

Embodiment 1-6

[0195] The external structuring system composition embodiment 1-6 of above-mentioned table 2, its preparation method is:

[0196] A) Under stirring, put surfactant (LAS), alkaline agent (liquid caustic soda), pH stabilizer (sodium citrate) and alkylarylsulfonic acid solubilizer (2,4-xylenesulfonic acid) into the reaction kettle in sequence Sodium acid, sodium p-toluenesulfonate or sodium cumenesulfonate), and the pH of the mixture in the reactor is adjusted to 6.0~10, preferably 7~8.5 with a pH regulator (citric acid);

[0197] B) Then heat to 80°C-95°C, preferably 90°C-95°C, then add 12-hydroxy-octearic acid triglyceride, and at this temperature, stir until all 12-hydroxy-octearic acid triglyceride Esters are fully emulsified;

[0198] C) cooling the mixture rapidly to 55°C-80°C, and keeping it at this temperature for 5 minutes-300 minutes, preferably 60 minutes-120 minutes;

[0199] D) Finally, slowly lower the temperature to below 40°C, preferably room temperature. The e...

Embodiment 1

[0210] Example 1: Step A added sodium 2,4-xylenesulfonate (0.5% added), and mixed 6 parts of the prepared external structuring system with 93 parts of "1# base liquid" and 1 part of pure water;

Embodiment 2

[0211] Example 2: In step A, sodium 2,4-xylenesulfonate (0.5% added) was added, and 6 parts of the prepared external structuring system were mixed with 93 parts of "2# base liquid" and 1 part of pure water.

[0212] Table 3 Tests of Exterior Structuring System Compositions

[0213]

[0214] Obviously, sodium 2,4-xylene sulfonate is fed preferentially over 12-hydroxy-octearic acid triglyceride in order to have an effect on the crystallization behavior of 12-hydroxy-octearic acid triglyceride, that is, to enhance the structure of liquid detergents ability.

Abstract

The invention discloses an external structured system composition for a liquid detergent, and the liquid detergent. The external structured system composition is prepared from the components in percentage by weight: (a) 0.01%-5% of 12-hydroxyl-18 triglycerides, (b) 0.01%-5% of an alkylaryl sulfonic acid solubilizer, (c) 5%-60% of surfactants, (d) 0.01%-10% of a pH stabilizer, a pH regulator and analkali agent, and (e) the balance of water, wherein as for the alkylaryl sulfonic acid solubilizer, the number of alkane chain carbon atoms is less than 5, and an anion surfactant accounts for at least 80% of the total amount of the surfactants in the composition. An external structured system has higher structured performance, that is, better suspension capacity is achieved under the same condition. The invention further discloses a preparation method of the external structured system composition, and application of the external structured system composition to the liquid detergent.

Description

technical field [0001] The invention relates to an external structuring system for liquid detergent and its preparation process, as well as a liquid detergent containing the external structuring system, belonging to the technical field of daily chemical products, in particular to liquid washing containing insoluble components Compositions and their applications. Background technique [0002] In addition to basic cleaning power, more and more detergent manufacturers are trying to give detergents more functional points, such as softness, color protection, and long-lasting fragrance. Powder or block products are generally produced by blending powder spraying or fluidized bed granulation of different materials, and can also be produced by blending different particles, so these functions are relatively easy to achieve in solid detergents. Since the compatibility of functional raw materials with the liquid detergent matrix will lead to delamination and precipitation of the deterg...
