Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a highly effective stain-removing pink laundry detergent and its preparation method. Background Technology

[0002] With the improvement of people's living standards and the enhancement of environmental awareness, consumers have increasingly diversified requirements for the performance of laundry products. Currently, there are many types of laundry detergents on the market, covering various functional types such as ordinary synthetic, enzyme-active, whitening, and fragrance-based detergents. Most laundry detergents exhibit good stain removal ability and cleaning efficiency at room temperature (approximately 30℃), especially those containing surfactants, enzymes (such as proteases, lipases, and amylases), and bleaching agents, which can effectively decompose protein, oil, and carbohydrate stains in a moderate-temperature environment.

[0003] However, in many northern regions of my country, indoor temperatures are generally below 25°C during the transition from winter to spring, and in some southern areas, effective indoor heating is lacking in winter, resulting in low water temperatures for washing clothes. During low-temperature washing, stains are difficult to remove from fabrics, easily causing secondary deposition and affecting washing results. To improve the washing effect, some users choose to use hot water or extend the washing time, increasing energy consumption and operating costs, failing to meet consumers' dual needs for efficient stain removal and energy conservation.

The RHLQ vertical stain remover specified in this national standard was used for testing, and three types of soiled cloths were tested using national standard carbon black JB-01, national standard protein JB-02, and national standard sebum JB-03.

[0104] Detergency testing conditions: 250 mg / kg hard water, washing concentration of 2 g / L, washing time of 20 min, temperatures of 30℃ and 15℃ respectively, washing and stirring speed of 100 r / min, and the use of the RQHL vertical detergency machine specified in the national standard.

[0110] As shown in Tables 1 and 2, the laundry detergents of Examples 1-5 exhibit excellent cleaning performance at 30°C, comparable to commercially available products. At 15°C, the cleaning performance of the laundry detergents of Examples 1-3 is more stable, showing little change compared to the 30°C condition. However, in Examples 4-5, due to changes in the ratio of plant extracts, anionic surfactants, and nonionic surfactants, the cleaning performance at low temperatures significantly decreased, as did the cleaning performance of commercially available products at low temperatures. This indicates that only the plant extracts prepared by the specific fermentation method of this invention can exert a synergistic effect with anionic and nonionic surfactants, improving not only the cleaning performance at 30°C but also the cleaning performance of the laundry detergent at low temperatures.

[0111] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
