Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a cleaning composition containing solid fermented Sapindus mukorossi fruit extract and its preparation method. Background Technology

[0002] Children's skin has unique physiological characteristics. The stratum corneum and epidermis are thinner than adults', with significantly higher water content and a pH closer to neutral (6.6-7.5), while adult skin is typically slightly acidic. These differences make infant skin more fragile and sensitive, requiring gentler and more protective care. Infants' skin structure is immature, with a thinner stratum corneum, smaller keratinocytes, denser skin texture, a weaker skin barrier than adults, and lower total lipid and sebaceous gland lipid content, making their skin prone to dryness.

[0003] While current children's shampoos and body washes on the market emphasize gentleness and non-irritation, many still contain highly irritating sulfate-based ingredients such as SLS and SLES, as well as potentially harmful ingredients like synthetic preservatives, artificial fragrances, and mineral oils. Existing technologies include several patents for children's personal care products containing natural surfactants. For example, patent CN111388370A discloses a two-in-one shampoo and body wash for children, containing 1-2 parts of Sapindus mukorossi fruit peel extract and 1-2 parts of tea seed extract. Patent CN106635481A discloses a daily-use environmentally friendly detergent containing natural surfactants such as tea saponin, Sapindus mukorossi saponins, and sophorolipids. However, none of these existing technologies have yet found a product specifically optimized for children's use by scientifically combining these four ingredients—solid-fermented Sapindus mukorossi fruit extract, tea saponin, sophorolipids, and amino acid surfactants. Summary of the Invention

[0004] To address the shortcomings and deficiencies of the existing technology, the primary objective of this invention is to provide a cleaning composition containing solid-fermented Sapindus mukorossi fruit extract. This cleaning composition achieves gentle cleaning, non-irritating, and easily biodegradable effects through the scientific blending of four natural surfactants: solid-fermented Sapindus mukorossi fruit extract, tea saponin, sophorolipids, and amino acid surfactants, making it particularly suitable for children's delicate skin.

Yeast culture was inoculated and solid-state fermentation was carried out. After fermentation, the fermentation product was extracted by countercurrent extraction with deionized water, purified by ultrafiltration membrane filtration, and vacuum concentrated and dried to obtain the solid-state fermented Sapindus mukorossi fruit extract.

[0012] This method features large-scale production, high output, low cost, and simple operation, making it suitable for industrialization.

[0013] Furthermore, the amino acid surfactant in the above-mentioned cleaning composition is one or a mixture of several of the following: sodium cocoyl glutamate, sodium lauroyl glutamate, sodium cocoyl sarcosinate, sodium lauroyl sarcosinate, sodium cocoylaminopropionate, and sodium lauroyl methyl taurate.

[0014] Furthermore, the auxiliary surfactant in the above-mentioned cleaning composition is one or a mixture of several of cocamidopropyl betaine, lauryl glucoside, decyl glucoside, and cocamidopropyl hydroxysulfonate betaine.

[0015] Furthermore, the moisturizer in the above-mentioned cleaning composition is one or a mixture of several of glycerin, propylene glycol, butylene glycol, sodium hyaluronate, and panthenol.

[0025] The application of the above-mentioned cleaning composition in children's shampoo and body wash.

[0026] Sapindus mukorossi fruit extract is an excellent natural nonionic surfactant. Its main surface-active components are triterpenoid saponins and sesquiterpenoid glycosides, which have a strong effect on reducing surface tension. It has been proven to have antibacterial, bactericidal, and anti-dandruff effects on human skin. Tea saponin is a glycoside compound extracted from the seeds of plants in the Theaceae family. It possesses excellent emulsifying, dispersing, wetting, detergency, and foaming properties, making it a high-performance natural surfactant. Sophorolipids are microbial secondary metabolites produced by the non-pathogenic yeast *Starmerella bombicola* using vegetable oils and sugars as raw materials through a specific fermentation process. They have good surface activity, extremely low CMC concentration, are non-toxic, non-irritating to the skin, and 100% biodegradable. Amino acid surfactants are currently the most commonly used mild ingredients in children's personal care products. They have extremely low irritation, and their irritation to the skin and eyes is far lower than that of traditional sulfate surfactants.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Mild and non-irritating: It adopts a compound system of four natural surfactants, among which amino acid surfactants are recognized as one of the mildest surfactants, with almost no negative impact on the skin barrier; the solid fermented soapberry fruit extract has a pH value between 5 and 7, is naturally acidic, and is mild in nature; tea saponin is practically non-toxic and safe to use; sophorolipids have passed skin irritation tests and are non-irritating to human skin.

[0029] 2. Synergistic Effect: By combining sophorolipids with amino acid surfactants and auxiliary surfactants, the surface activity and cleaning effect of the system can be significantly improved. Simultaneously, the use of solid-state fermented Sapindus mukorossi fruit extract and tea saponins ensures good surface activity and cleaning effect while maintaining skin moisture and providing nourishment. Therefore, it effectively cleanses children's skin and hair with a cleaning power greater than 50% without excessively removing the skin's natural oils, leaving skin and hair feeling moisturized after washing.

[0030] 3. Tear-free formula: Through scientific formula design and pH adjustment, the product's eye irritation index is less than 0.5, which meets the national tear-free formula standard.

[0031] 4. High safety: It does not contain strong irritating sulfate ingredients such as SLS and SLES, nor does it contain harmful ingredients such as alcohol, pigments, and mineral oil. It is 100% biodegradable and environmentally friendly.

[0032] 5. Good stability: Through the use of chelating agents and reasonable process control, the product can remain stable under different temperature conditions, without layering or precipitation. Detailed Implementation

[0033] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0034] The solid-state fermented Sapindus mukorossi fruit extract described in the following examples was prepared using the following method:

Then, a yeast culture diluted with sterile water (commercially available yeast culture) was inoculated into the fermentation substrate. Solid-state fermentation was carried out with the moisture content of the fermentation material controlled within the range of 55-65% at 30°C for 4 days. After fermentation, the fermentation product was extracted with deionized water at 75°C countercurrently for 2 hours. The extract was purified by ultrafiltration, vacuum concentrated, and dried to obtain the solid-state fermented Sapindus mukorossi fruit extract.
