Description

Multifunctional laundry detergent and preparation process thereof
Technical Field
The invention relates to a laundry detergent and a preparation process thereof.
Background
The traditional washing powder and soap adopt anionic surfactants which mainly comprise sodium alkyl sulfonate and sodium stearate and have strong alkalinity, so that the soap has large irritation and damage to skin when in use, while the washing liquid mostly adopts nonionic surfactants, the pH value is close to neutral, the washing liquid is mild to skin, and after being discharged into the nature, the washing liquid is degraded faster than the washing powder, so the soap becomes a new generation of detergent. The other purpose of developing the laundry detergent is to overcome the defect of inconvenient powder use while maintaining the excellent washing performance of the washing powder. The laundry detergent can bring convenience to daily life of consumers, compared with powder products, the liquid products are easier to dissolve, especially under the condition of low temperature, dust is less in the production process, and metering is easy and accurate. The technical content of the laundry detergent is higher, various active ingredients are convenient to add, clothes are fluffy, soft, smooth and bright when being washed, and the laundry detergent has the effects of sterilization and lasting fragrance. The comprehensive use cost is low, and the method is widely accepted by people. The current research on laundry detergents is mainly focused on the protection of fabric appearance and color, and it is expected that the color and texture of the fabric can be kept better after the fabric is washed for a plurality of times. These techniques also include the continuous synthesis of new macromolecules to reduce dye transfer (cross-staining) during washing, the focus on the use of new enzyme preparations in laundry detergents and to reduce the breakdown of enzyme preparations, among others.
Due to the fact that the conventional laundry detergent is limited in decontamination effect, the application of the enzyme preparation in the laundry detergent obviously improves the use performance of the laundry detergent, not only on substrates acted by the enzyme preparation, such as grass stains and blood stains targeted by protease, but also improves the removal capacity of conventional stains. Since in actual stains the protein is often immobilized on the fabric along with other soils, removal of the protein may also help remove other soils mixed with the protein. However, the enzyme in the laundry detergent is often decomposed or inactivated in the process of long-term storage, so that the decontamination effect of the laundry detergent containing the enzyme is reduced, and how to maintain the activity of the enzyme becomes a problem to be solved urgently.
The current washing machine also faces a problem: when the clothes which are easy to fade are washed together with other clothes, other clothes are dyed, people often need to wash the clothes separately according to colors, and the traditional laundry detergent cannot solve the problems.
Compared with the traditional laundry detergent, the laundry detergent is low in alkalinity, mild in performance and free of damage to clothes and hands, but the laundry detergent is often added with Chinese herbal medicine extracts, antibacterial agents, antistatic agents, softening agents and other components, so that certain irritation such as itching and burning can be brought when the laundry detergent is used for hand washing, and how to improve the hand washing experience of a user is a problem needing to be researched.
The multifunctional laundry detergent contains a surfactant, protease, cellulase, an enzyme activity maintaining agent, a cacumen biotae flavone extract and a garden balsam stem extract which are scientifically proportioned, can effectively remove oil stains, blood stains, coloring agents and the like on clothes, is added with a novel adsorbent for adsorbing dyes and dirt and a freshener with a cooling and itching relieving effect, improves the use experience, and is soft, elastic and high in comfort level after being washed by the detergent.
