Background
The cleaning of clothes is a part of daily life of people, and since the advent of soaps, products such as washing powder and laundry detergent are developed in industry, and the washing products bring great convenience and meet the requirement of consumers on clothes cleaning. The soap is prepared by saponifying natural oil, has strong dirt-removing power, but is not hard water resistant, easily generates substances which are difficult to dissolve in water and deposits in the gaps of clothes fibers, and is only suitable for hand washing but not machine washing because the soap is basically in a block shape. The detergent powder has very strong decontamination effect and can play a very good cleaning effect on dirtier clothes, but the detergent powder is not easy to dissolve and rinse and has great damage to the clothes; easily remain on clothes, and may cause allergy and roughness after contacting with skin. Compared with soap and washing powder, the laundry detergent has the advantages that: the laundry detergent is high in hydrophilicity, easy to dissolve and rinse, milder and less in damage to clothes and skin, the clothes washed by the laundry detergent are soft and fluffy, the laundry detergent does not contain phosphorus generally, the laundry detergent is discharged outdoors, and the laundry detergent has little influence on the environment and is relatively environment-friendly. Therefore, more and more people choose to use the laundry detergent, and various laundry detergent products are also available on the market. Application No.: 201710711350.2 discloses an infant laundry detergent, which comprises the following components: 10-20 parts of sodium dodecyl benzene sulfonate, 5-8 parts of alkyl sodium sulfate, 1-3 parts of hydroxymethyl cellulose, 3-8 parts of polyethylene glycol, 5-10 parts of soap, 0.1-0.3 part of essence, 10-15 parts of surfactant, 10-15 parts of cation conditioner, 10-15 parts of sodium perborate, 18-28 parts of sodium carbonate, 0.5-1 part of tea tree oil, 0.2-0.3 part of mature vinegar, 0.2-0.3 part of chamomile extract and the balance of deionized water. The infant laundry detergent prepared by the method disclosed by the invention is simple in process, low in cost, good in decontamination effect, free of corrosive factors, free of hand injury, easy to rinse and free of residues.
With the increasing health awareness of consumers, the cleaning of clothes has not been satisfactory for removing visible dirt such as oil stains, dust, etc., and it is also desirable to kill bacteria harmful to the human body. The traditional laundry detergent can only perform a decontamination effect on clothes, but cannot perform a bacteriostatic effect, so that the bacteriostatic laundry detergent capable of simultaneously performing decontamination and sterilization needs to be developed.

The fatty alcohol-polyoxyethylene ether AEO-9 has excellent biodegradability, is not influenced by water hardness, and has good compatibility with other surfactants.
Potassium fatty acid soaps belong to the class of anionic surfactants and have a greater wetting, penetrating, dispersing and detergency capacity than sodium soaps. Good compatibility with anionic and nonionic surfactants, abundant foam and obvious cleaning effect.
The coconut diethanolamide belongs to a nonionic surfactant, is easy to dissolve in water, and has good foaming, foam stabilizing, penetrating, decontamination and hard water resistance.
The cocamidopropyl hydroxysulfobetaine belongs to a zwitterionic surfactant, is easy to dissolve in water, has stable property under an acid-base condition, and has excellent softness, bactericidal property, antistatic property, hard water resistance, strong detergency, no toxicity and low irritation. The product is often used together with anionic, cationic and nonionic surfactants, has good compatibility, and can remarkably improve the softness, conditioning and low-temperature stability of the product by compatibility.
The bacteriostatic principle of the silver ions is as follows: ag+Can strongly attract the sulfhydryl (-SH) on the protease in the bacterial body, and can be rapidly combined with the sulfhydryl (-SH) to make the protease lose activity, so that the bacteria can be killed. When bacteria are covered by Ag+After killing, Ag+The bacterial corpse is dissociated and then contacted with other bacterial colonies, and the process is repeatedly carried out, so that the effect of durable sterilization is achieved.
The borneol camphor oil is prepared by distilling and extracting fresh branches and leaves of borneol camphor, is a natural plant extract, is safe and nontoxic, mainly comprises d-borneol, camphor oil, alpha-pinene, d-limonene and 1, 8-cineole, and has an inhibiting effect on gram-negative bacteria, gram-positive bacteria, fungi and mold.
By adopting the technical scheme, the invention has the beneficial effects that:
through a large amount of researches, the formula is reasonably adjusted, and the antibacterial laundry detergent prepared by the invention is mild and non-irritant; the used various surfactants have good compatibility, the laundry detergent obtained by compounding the surfactants according to a certain proportion has strong dirt-removing power, good wettability and permeability, and the washing effect is not influenced by water hardness; the laundry detergent disclosed by the invention can play a role in bacteriostasis while ensuring cleanliness, safety and mildness, the cocamidopropyl hydroxysulfobetaine in the surfactant can remove dirt and has a certain antibacterial effect, and a certain amount of natural bacteriostat silver ions and natural plant extract borneol camphor wood oil are added on the basis, so that the bacteriostasis effect of the laundry detergent is enhanced, and the laundry detergent has good killing power on staphylococcus aureus, escherichia coli and the like. The single bacteriostatic active component has narrow antibacterial spectrum and poor bacteriostatic activity, and is easy to generate drug resistance. According to the invention, silver ions and borneol camphor oil are applied to the laundry detergent, so that the addition amount of the original chemically synthesized preservative can be reduced, and the laundry detergent is safer and more environment-friendly.
2. The laundry detergent can be well thickened by adding a small amount of the thickening agent, the appearance of the laundry detergent is not influenced, the effect of the surfactant is not weakened, the phenomena that stock solution is easy to splash and the waste is easily caused due to high fluidity can be solved, and the laundry detergent is more favorable for consumers to use. According to the invention, no thickening agent is required to be added, and the cocamidopropyl hydroxysulfobetaine in the formula has a thickening property on the fatty acid potassium soap while playing a decontamination role, so that the viscosity or consistency of the product is improved.
3. The isomeric alcohol XP-89 nonionic surfactant has strong permeability, can permeate into fiber gaps to clean dirt hidden in the fiber gaps, and can also promote active components to migrate to the surface of bacteria and permeate into the bacteria to enhance the sterilization effect. In addition, the isomeric alcohol XP-89 serving as a nonionic surfactant also has excellent softness, and the softness of the product is obviously improved.
4. The vacuum emulsification pot is used for production, so that the temperature can be better controlled, the raw materials are prevented from discoloring due to overhigh temperature, and the properties are unstable. Meanwhile, air and microorganisms cannot enter mixed raw materials in the pot during stirring, so that less foam is ensured in the production process, microbial pollution cannot occur, the quality of the product is reduced, and the prepared finished product has stable and uniform quality.
