Currently, the suspension type products, which are the mainstream in the market, are usually built up by some polymers, such as carbomer, acrylic (ester) polymers (cross-linked copolymers), modified cellulose, xanthan gum, gellan gum, etc. For the development of a suspension system, attention needs to be paid to the compatibility of a high molecular polymer suspending agent and activity and other additives in the system, and the high molecular polymer often has the problems of intolerance, poor compatibility and the like to electrolytes, surfactants and the like in the system, such as intolerance of some series of carbomers (940, 980 and the like) to ions; poor compatibility between the modified cellulose and nonionic surfactant, and the like. Such problems limit the application of high molecular polymer suspending agents to a great extent, and increase the difficulty of the development of a suspension system. Meanwhile, although these high molecular polymers can provide a certain suspension effect, in order to maintain stable suspension property and stability at high and low temperatures, a high addition amount is often required, and a large amount of high molecular polymers can cause the foaming capability of the cleaning composition to be obviously inhibited, so that the foam is rare and collapsed, the foam stability is poor, and the defoaming is fast; moreover, the high molecular polymer often generates obvious residual feeling on the skin and generates ' pseudo-smooth ' skin feeling, and the defects of the residual feeling and the pseudo-smooth ' skin feeling cause very obvious reduction of experience feeling on the cleaning products, thereby reducing the repurchase rate of the products for consumers.

Effect testing

(1) Stability Performance test

The suspension cleaning compositions prepared in the above examples 1 to 7 and comparative examples 1 to 9 were subjected to stability performance tests, respectively, in test environments including room temperature, 45 c (standing for 4 weeks), 4 c (standing for 4 weeks), and-15 c (returning to room temperature after standing for 4 weeks); the test results are shown in table 3 below.

Table 3: comparison of stability of suspended cleaning compositions of examples 1-7 and comparative examples 1-9

From the test results of examples 1-7 in Table 3, it can be seen that a system consisting of a suspended cleaning composition formulation of the present invention can achieve stable suspension of particles even when left for a long period of time (more than 4 weeks) at ambient temperature, 45, 4, -15 ℃; meanwhile, the liquid emulsion and the oil phase liquid beads can be suspended through the system, so that stable suspension is realized.

As can be seen from the test results of comparative example 2 and comparative examples 1-2 and the graph of FIG. 1, in the absence of nonionic surfactant, fatty acid, fatty alcohol as structure inducer, the system could not form stable liquid crystal structure, the low static viscosity of the system (962 mPa. multidot. s for comparative example 1 and 720 mPa. multidot. s for comparative example 2) resulted in the suspension failure of the particles, while example 2 with reasonable formulation, the static viscosity reached 44700 mPa. multidot. s, which is much higher than that of comparative examples 1-2, achieved stable suspension of the particles, and at the same time, example 2 had significant shear thinning property, with shear rate of only 1s^-1The viscosity of the product becomes about 1/30000 which is the static viscosity, and this provides the possibility of the formulation improving the quality skin feel such as extensibility and spreadability in the product. Meanwhile, the test results of comparative example 3 also revealed that the suspending effect was not exhibited when the weight ratio of the fatty acid, the fatty alcohol and the nonionic surfactant was out of the specified range; in comparative example 4, too low an amount of the amphoteric surfactant causes the system structure not to be formed and thus the particles cannot be suspended; the test results of comparative example 5 show that when the pH value of the system is beyond the specified range due to excessive addition of sodium citrate or other pH regulators (the pH value of the 10% solution of the comparative example 5 system is 7.21), the liquid crystal structure of the system is also affected, and the suspension effect is lost.

Comparative examples 6-9 provide for the construction of a suspension system based on polymers and the results of the tests show that when suspending higher density particles such as walnut shell flour, more polymer addition is required which otherwise results in insufficient suspension force and sinking of the particles (as shown in comparative example 7).

(2) Experience testing

The actual experience feeling test conditions are 30 volunteers (male-female ratio is 3:7), and the products (example 3 and comparative examples 6-9) are subjected to scoring feedback statistics after being used according to a normal method, so that all the volunteers can truly reflect the feeling after being used. The scoring standard is that the score is 1 lowest and the score is 5 highest, and the index evaluation result is the average value of the scores. The test results are shown in table 4.

Table 4: actual feel score comparison of suspended cleaning compositions

From the results of the actual experience test in table 4, it can be seen that in the system with the same type and amount of the main blowing agent, the formulations of comparative examples 6 to 9, which contain different types of high molecular polymer suspending agents, including acrylic polymer, acrylic/C10-30 alkanol acrylate cross-linked polymer, resulted in significantly reduced foam performance of the system, especially in terms of foam amount, and at the same time, the easy-to-wash property of the system also significantly decreased, resulting in increased residual feeling and "pseudo-slip feeling"; in contrast, in comparative example 7, the foam properties of the suspension were improved as compared with comparative examples 6, 8 and 9 due to the addition of a small amount of the suspension agent (3% SF-1), but it was found from the stability test results in table 3 that the suspension agent added in a small amount did not provide stable suspension, and particles fell/floated in the system, resulting in unstable products, especially in the case of suspending oil phase droplets, phase separation was easily occurred.

In summary, according to the test results in tables 3 and 4, it can be seen that the cleaning composition of the suspending agent provided by the present invention can form a stable liquid crystal structure by reasonably matching the surfactant, the structure-inducing agent (nonionic surfactant, fatty acid and fatty alcohol), the inorganic salt and other auxiliaries without adding the suspending agent, so as to achieve the suspending effect, and thus, the disadvantage of poor experience of foam and skin feel caused by the addition of the high molecular polymer in the suspended cleaning product can be solved. Meanwhile, the cleaning composition of the suspending agent provided by the invention can be correspondingly adjusted within the scope of the invention according to the product types and the people facing to the product, so that the aim of adjusting the functions, the appearance and the use form of the product can be fulfilled.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
