Description

Aerobic soap powder composition with sterilization function and preparation method thereof

Technical Field

The invention relates to a soap powder composition, in particular to an aerobic soap powder composition with a sterilization function and a preparation method thereof.

Background

The soap powder is a washing product combining washing and protecting functions, and has the characteristics of nature, strong decontamination, ultra-low foam, easy rinsing and the like. The active substances of the plant oil-water mixture are mainly fatty acid, more than 90% of raw materials are from renewable vegetable oil and fat, and the plant oil-water mixture does not contain polyphosphate. The soap powder has low irritation to skin, protects fabrics, and enables washed clothes to be fluffy and soft without using a softener, thereby solving the problems of deposition, hardening, electrostatic charge and the like of fabric dirt after multiple washing. Because the special calcium soap dispersing agent is added into the soap powder, the detergency is stronger and is 1.3 to 1.5 times that of the common washing powder; it also does not require water as much as soap and exhibits excellent cleaning performance even in low temperature and high hardness water. The soap powder also overcomes the defect that the washing powder stimulates the skin, and the washing effect is more excellent.

Compared with common synthetic washing powder, the natural soap powder has low skin irritation, high safety, fluffy and soft washed clothing and comfortable feeling, and solves the problems of ' dirt deposition, ' hardening ' and ' static ' of the fabric washed by the synthetic washing powder. Secondly, because the natural soap powder is added with the special calcium soap dispersing agent, the detergency is stronger, and the fragrance is more durable. The carved natural soap powder is tested according to the standard, the decontamination ratio is close to that of concentrated washing powder, and the carved natural soap powder still shows excellent washing performance in low-temperature and high-hardness water. In addition, the fragrance is strong, and the fragrance is still remained after the fabric is washed to be dry. And thirdly, the foam is ultra-low, so that the fabric is easier to rinse. Many people think that the more abundant the washing powder foam, the easier the clothes can be washed clean, actually, in developed national markets such as europe, america and the day, the ultralow foam powder accounts for the absolute share of the market, so that the ultralow foam natural soap powder is more in line with the international fashion trend.

According to investigation, the utilization rate of the soap powder on the market is low, and the soap powder is very suitable for people needing hand washing, especially students in schools. The soap powder which is generally expected to be a little in the supermarket is carved natural soap powder, super-energy natural soap powder, natural soap powder in standing days and natural laundry soap powder. The main reasons for the low utilization rate of the soap powder are that the propaganda strength of enterprises and the consumption consciousness of people are not enough, and on the other hand, the antibacterial performance of the existing soap powder is not strong. The fact becomes an important factor which troubles the market popularization of the soap powder, and the research of the soap powder with effective sterilization has become an urgent need in the market.

Sodium percarbonate, of the formula: 2Na₂CO₃·3H₂O₂(or Na)₂CO₄) It is also called sodium carbonate peroxide, commonly called solid hydrogen peroxide, and is an inorganic salt in the form of white granular powder, and its aqueous solution is alkaline, and can be decomposed into sodium carbonate and hydrogen peroxide. The sodium percarbonate has the advantages of no toxicity, no odor, no pollution and the like, and also has the characteristics of bleaching, sterilization, washing, good water solubility and the like.

Sodium percarbonate is commonly used as an adjunct to laundry detergent powders, has the effect of oxygen-based bleaching and is effective in increasing dissolved oxygen in fishpond management, and in commercial applications, it is commonly coated with sulphate and silicate materials to obtain coated sodium percarbonate to increase the storage stability requirements in laundry detergent compositions. Compared with the traditional laundry bleaching auxiliary agent which is sodium percarbonate, the sodium percarbonate has the advantages of good storage stability and good compatibility with other washing powder components, which is incomparable and irreplaceable with sodium perborate. From the chemical structure, the essential difference is that sodium percarbonate exists in the nature of an adduct, and sodium perborate is a bonded product.

Patent application CN03112493.3 provides a preparation method of natural soybean oil residue soap powder, belonging to washing and chemical products, the raw materials are composed of soybean oil residue, high-efficiency auxiliary agent and mixed solvent, the soap powder comprises the following raw materials by weight: 100 parts of soybean oil residue, 10-50 parts of an auxiliary agent, 5-40 parts of a solvent, 10-40 parts of 50% dilute sulfuric acid, 10-40 parts of caustic soda and 1-10 parts of 30% hydrogen peroxide. It has certain bacteriostasis effect, but the washing performance and the flowing dispersibility are not good. Patent application CN201410129416.3 discloses a laundry soap special for infants, which is composed of the following raw materials in parts by weight: 80-90 parts of natural soap powder, 10-20 parts of coconut oil fatty acid diacetyl amide, 15-20 parts of glycerol, 8-12 parts of aloe extract, 5-10 parts of tea tree oil and 5-15 parts of citric acid, and the antibacterial effect is poor.

Experiment example two: flow dispersancy test

The angle of repose of each soap powder was measured by an angle of repose tester in reference to GB-T11986-98, and the smaller the angle of repose, the better the flow dispersibility, and the measurement results are shown in Table 4:
