[0051] The preparation method of the thickening stabilizer is as follows: heat and dissolve the amino acid surfactant in deionized water, add nonionic surfactant, soybean lecithin and fatty acid in sequence, continue heating to above 95°C until it is completely dissolved, and continue stirring 30min, cool down, and cool to room temperature.
[0052] Wherein, the adsorption accelerator is composed of the following components calculated in weight percent:
[0053] Amino acid surfactant 5-50%
[0054] Inorganic salt 0.5-5%
[0055] Deionized water balance.
[0056] Preparation of adsorption promoter: Heat the amino acid surfactant in an appropriate amount of deionized water to above 95°C, dissolve completely, stir evenly, add an appropriate amount of inorganic salt, continue stirring for 30 minutes, and cool to room temperature.
[0057]The adsorption accelerator utilizes the interaction between the amino acid surfactant and the cationic conditioning agent to effectively promo...

[0067] The composition of the thickening stabilizer in the silicone-free mild conditioning shampoo composition of the present invention:
[0068]
[0069] The preparation method of the thickening stabilizer: put sodium lauroyl sarcosinate and sodium lauroyl glutamate into deionized water and heat to dissolve completely, then add cocoyl glucoside, hydrogenated soybean lecithin and coconut oil fatty acid monoethanolamine in sequence, continue Heat to above 95°C until the dissolution is complete, and continue to stir for 30 minutes, lower the temperature, and cool to room temperature to obtain the product.
[0070] The thickening stabilizer is a layered liquid crystal (spherical) structure under a polarizing microscope, see figure 1 . The thickening stabilizer is used in shampoos and can induce the amino acid surfactant solution to form liquid crystals in a specific form to achieve the purpose of self-thickening, thus significantly improving the suspension stability and condi...

[0072] The composition of the medium adsorption accelerator in the non-silicone oil mild conditioning shampoo composition of the present invention:
[0073]
[0074] The preparation of the adsorption accelerator: weigh each component according to the above formula ratio, and heat sodium cocoamidopropionate, sodium lauroyl glutamate, and sodium lauroyl aspartate in an appropriate amount of deionized water to 95 Above ℃, dissolve completely, stir evenly, add sodium chloride, continue to stir for 30min, cool to room temperature, that is.
[0075] The adsorption accelerator utilizes the interaction between the amino acid surfactant and the cationic conditioning agent to effectively promote the adsorption of the conditioning agent on the hair, greatly enhancing the adsorption efficiency of the cationic conditioning agent, thereby improving the conditioning effect.
