Description

Cleaning composition
Technical Field
The present invention relates to the field of personal care, and in particular to a cleansing composition that is aesthetically pleasing, transparent, fluid, and easily extrudable.
Background
The shower gel is a large consumer product with high consumption in daily chemical products, but the bath products in China only have a single variety of soap for a long time. Until the early eighties, Shanghai soap makers produced "bee flower" brand liquid soap, which is the precursor of bath lotion today. By the last ninety years of the last century, body washes began to develop and become popular and rapidly growing. Nowadays, toilet soaps have been replaced by body washes basically due to the characteristics of sanitary and convenient use of body washes. Moreover, the shower gel is developed to the present, and not only the effect of cleaning the skin is achieved, but also the shower gel has the functions of lasting fragrance, mild skin care and the like, and integrates the functions of cleaning, fragrance retaining and skin care.
However, different types of shower gels still have some disadvantages, such as over-dry and tight skin after the soap-based shower gel is washed, difficult thickening and stability of amino acid shower gel, poor body fluidity of anionic surfactant type shower gel at low temperature after being thickened by sodium chloride and the like, so that the research and development of the shower gel still have great space and opportunity, and particularly the shower gel using the most widely anionic surfactant at present.
Detergent manufacturers are constantly seeking to improve the cleaning performance and/or aesthetics of their liquid detergent compositions. Surfactants are typically the major cleaning ingredients of such compositions, and anionic surfactants such as Alkyl Ethoxylated Sulfate (AES) surfactants are commonly used. Compositions containing relatively low levels of surfactant (e.g., less than 20 wt.%) present particular challenges. For example, compositions with relatively low surfactant content may appear thin or runny to the consumer, meaning low quality and/or poor performance. The viscosity of such compositions can be increased by the addition of external thickeners such as salts or structurants, but the use of such materials results in additional costs and does not provide additional detergency benefits. Additionally, it has been found that the cleaning benefits (e.g., removal of greasy soils) of certain liquid detergent compositions can be improved by formulating with AES surfactants having relatively increased alkyl chain lengths (e.g., C14 or longer). However, excessively long average AES chain lengths (as may be reflected in the weight average molecular weight of alcohols having those chain lengths) may result in poor physical stability of the detergent composition. Accordingly, there is a continuing need to provide improved liquid detergent compositions which provide good performance, viscosity and/or stability.
Shower gels based on sodium lauryl ether sulfate and/or lauramide betaine surfactant combinations, typically use NaCl to adjust viscosity. The viscosity of the system varies with temperature. The outstanding problems existing in the prior art are that; if the viscosity is adjusted to 7000cps at 25 deg.C, the shower gel will appear like "jelly" at 10 deg.C, which will adversely affect normal use. Possible solutions include: the viscosity is adjusted to be below 4000cps at 25 ℃, although the jelly phenomenon at 10 ℃ can be relieved, the shower gel is too thin at 25 ℃.
Thus, there is also a need in the art to provide a personal care product that is transparent and aesthetically pleasing in appearance and exhibits excellent flow extrusion properties.

The instrument was calibrated before testing by first rinsing the electrodes with deionized water and then blotting with filter paper. The electrode was carefully inserted into the sample, the electrode was submerged, and the reading was recorded after the pH meter reading stabilized.

Test example 7: stability test
After measuring the pH and viscosity of examples 25 to 36, stability was examined.
pH test method:
a sample (accurate to 0.1g) was weighed in one portion, added nine portions of laboratory deionized water, heated to 40 ℃ and stirred continuously until homogeneous, cooled to room temperature and tested using a pH meter (Metler FE28, LE438 electrode). The instrument was calibrated before testing by first rinsing the electrodes with deionized water and then blotting with filter paper. The electrode was carefully inserted into the sample, the electrode was submerged, and the reading was recorded after the pH meter reading stabilized.
Viscosity test method:
after the sample has been allowed to equilibrate at 25 ℃ for 24 hours, it is removed and placed in the viscosity rotator, the viscometer (Brookfield PV-S) is started and the reading recorded after 30 seconds.
The stability evaluation method was as follows:
the liquid cleaning compositions prepared in examples 25 to 36 were placed in a high temperature (48 ℃, 25 ℃, 4 ℃) stable incubator and examined for 30 days. And observing whether the sample has the conditions of particle solid precipitation, material body jellification, delamination and the like. If the sample is not changed normally before and after a certain time within 30 days, the sample is indicated as 'passing', the phenomenon of particles is indicated as 'precipitation', the phenomenon of solidification and difficult flowing of a material body is indicated as 'jelly', and the phenomenon of upper and lower layers of liquid is indicated as 'layering'. The results are shown in the following table.
Table 7 shows the results of stability studies of the liquid cleaning compositions of examples 25-36.
TABLE 7
Figure BDA0002837485760000231
As can be seen from the results in Table 7, cleaning compositions were prepared using different types of surfactants and the effect of the thickener benzyl benzoate on the thickening effect and stability of a range of cleaning compositions was examined. From the results of the above table test, it can be seen that the thickener benzyl benzoate has a significant thickening effect on cleaning compositions of the anionic surfactants sodium lauryl sulfate, ammonium mono C12-14 alkyl sulfate salt and the amphoteric surfactant sodium lauroamphoacetate, and the stability test is examined. The thickener benzyl benzoate has no obvious thickening effect on the cleaning composition prepared from the amphoteric surfactant lauramidopropyl betaine, the nonionic surfactant decyl glucoside and the amino acid surfactant sodium lauroyl sarcosine.
