Problems solved by technology

P-chloro-m-xylenol (PCMX), although it has a killing effect on most semi-Langer's rigid and negative bacteria, fungi and molds, is a low-toxicity antibacterial agent, but its solubility in water is only 0.03%. Afterwards, it is easy to remain on the skin, and there are certain safety hazards
In the invention patent with the publication number CN101176700A, povidone iodine is used as a bactericide, combined with sodium lauryl sulfate, nonylphenol polyoxyethylene ether, and sodium dodecylbenzenesulfonate to prepare an antibacterial and disinfecting hand sanitizer. The bactericidal effect of povidone-iodine is produced by the gradual decomposition of free iodine, of which 80%-90% of the combined iodine can be depolymerized into free iodine, which directly denatures the protein in the pathogen to kill the pathogen cells, thereby achieving disinfection and sterilization For the purpose, povidone iodine is often used to treat gynecological diseases. Using povidone iodine with disinfectant hand sanitizer is costly, and long-term use will cause tolerance to bacteria, which is not easy to popularize and promote

Abstract

The invention discloses a liquid soap with sterilizing and skin protecting functions and a preparation method thereof, which relates to the field of cleaning and skin protection. The liquid soap comprises active ingredients including anion and nonionic surfactants and assistants including skin-protecting agent, sanitizer, humectant, lubricant, chelating agent and pH value regulator. The components above are synthesized to prepare a viscous transparent liquid which has a nearly neutral pH value, and the preparation process thereof does not need any complex equipment. The liquid soap has strong soil removability, little skin irritation, mild effect, refined and smooth foam and a disinfection function which effectively prevents germ from breeding. The liquid soap is added with skin protecting ingredient and therefore can prevent skin from being chapped and improve frizzing resistance to frost; and thus, the liquid soap can be normally used even in winter in northern areas.

Description

technical field [0001] The invention belongs to the field of cleaning and skin care, and in particular relates to a sterilizing skin care hand sanitizer and a preparation method thereof. Background technique [0002] Antiseptic skin care hand sanitizer is a cleaning product that is widely used in urban and rural areas across the country. Now, as an alternative product of traditional hand soap, hand washing has many advantages. Its liquid characteristics can be easily added with various adjuvants, such as bactericidal disinfectants, fat-filling emollients, moisturizers, thickeners, etc., suitable for various needs of different groups of people. With the change of people's personal hygiene habits, especially after experiencing the "SARS" in 2003 and the "flu" in 2009, people's awareness of daily disinfection has gradually increased, especially the importance of hand hygiene and disinfection awareness has gradually increased. In order to avoid washing hands The cross-infectio...
