Description

cleaning composition technical field

The present invention relates to the field of personal care, in particular to a cleaning composition, which is beautiful and transparent in appearance, flowing and easy to extrude.

Background technique

Shower gel is a kind of bulk consumer goods with high consumption among daily chemical products, but in my country, bath products have long been only a single variety of soap. Until the early 1980s, Shanghai Soap Factory produced "Bee Hua" brand liquid soap, which is the predecessor of today's shower gel. Then in the 1990s, body wash began to develop and become popular, and it grew rapidly. Nowadays, due to the hygienic and convenient use of shower gel, soap has been basically replaced by shower gel. Moreover, the development of shower gel so far has not only achieved the effect of cleaning the skin, but also has the functions of lasting fragrance, gentle skin care, etc., and is a multi-effect shower gel that integrates cleaning, fragrance retention and skin care.

However, different types of body wash still have some drawbacks, such as soap-based body wash after washing, the skin is too dry and tight, amino acid body wash is not easy to thicken and stabilize, and anionic surfactant type body wash is thickened with sodium chloride at low temperature conditions. The fluidity of the blanking body is poor, etc., so there is still a lot of space and opportunities for the research and development of shower gels, especially for the most widely used anionic surfactant shower gels.

Detergent manufacturers are constantly seeking to improve the cleaning performance and/or aesthetics of their liquid detergent compositions. Surfactants are typical primary cleaning ingredients for such compositions, and anionic surfactants such as alkyl ethoxylated sulfate (AES) surfactants are commonly used. Compositions containing relatively low levels of surfactant (eg, less than 20% by weight) present particular challenges. For example, compositions with relatively low levels of surfactant may appear thin or runny to the consumer, meaning low quality and/or poor performance. The viscosity of such compositions can be increased by adding external thickeners such as salts or structurants, but the use of such materials incurs additional cost without providing additional detergency benefits. Additionally, it has been found that the cleaning benefits of certain liquid detergent compositions (eg, removal of greasy soils) can be improved by formulating with AES surfactants having relatively increased alkyl chain lengths (eg, C14 or longer). ). However, excessively long average AES chain lengths (as 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.

Body washes based on a combination of sodium lauryl ether sulfate and/or lauramide betaine surfactants typically use NaCl to adjust viscosity. The viscosity of this system varies with temperature. The outstanding problem existing in the prior art is that, for example, when the viscosity is adjusted to 7000cps at 25°C, the body wash at 10°C exhibits a "jelly-like" phenomenon, which adversely affects normal use. Possible solutions include: adjusting the viscosity to below 4000cps at 25°C, although the "jelly" phenomenon at 10°C can be alleviated, the body wash appears too "thin" at 25°C.

Therefore, there is also a need in the art to provide a personal care product, which is transparent and beautiful in appearance, and has excellent flow and extrusion performance.
