Abstract

The invention discloses a sterilization hand sanitizer containing microcrystal salt particles and a preparation method thereof, and belongs to the technical field of daily chemicals. The hand sanitizer consists of the following raw materials in percentage by mass: 15.0 to 30.0 percent of salt, 12.0 to 25.0 percent of surfactant, 3.0 to 8.0 percent of moisturizer, 0.5 to 3.0 percent of thickener, 0.1 to 0.5 percent of essence, 0.1 to 2.0 percent of pH regulator and the balance of pure water. Through intensively study on the characteristics of the hand sanitizer with high salt content and by combining the requirement of hand washing function and optimizing the formula, the sterilization hand sanitizer is finally compounded by adopting a unique multi-element formula, so the liquidity of the sterilization hand sanitizer is similar to that of common hand sanitizer; and the microcrystal salt particles can be felt in the sterilization hand sanitizer.

Description

A kind of crystallite salt grain disinfection hand cleanser and preparation method thereof that contains
Technical field
The invention belongs to the household chemicals technical field, particularly a kind of crystallite salt grain disinfection hand cleanser and preparation method thereof that contains.
Background technology
People's hand-washing article in the past mainly is soap, fancy soap or the like. easy landing when they use, chance water logging, high temperature can soften again and expend naturally, especially easily are infected with on hand dirt, antibacterial, become the secondary pollution source.Along with the transformation of growth in the living standard and consumption idea, handwashing liquid becomes the succedaneum of traditional hand-washing article gradually, has been widely used in various places such as hospital, hotel, food and drink, family at present.The contact surface of handwashing liquid and hands generally is the bottle pump head, and is easy to clean, avoided cross infection.By the squash type amount of getting, only need one press nozzle gently, liquid just flows into the palm of the hand, and consumption is by own grasp, and it is all very convenient to deposit use.Nowadays, along with the maturation of handwashing liquid production technology and popularizing of market, the special-purpose handwashing liquid with various special efficacies has also constantly come out.As the heavy duty detergent handwashing liquid, except that paint handwashing liquid, anhydrous washing hand liquid, disinfection handwashing liquid or the like.Wherein, the disinfection handwashing liquid is a class of occupancy volume maximum in the special-purpose handwashing liquid in market.
It is reported, the handwashing liquid that generally uses on the present market, part has bactericidal effect, but aspect the sterilization propaganda, common existence enlarges false words, because country does not have certain standard to define to the bacteria-eliminating efficacy of product, so Ministry of Public Health requires from July 1st, 2005, and the cosmetics of new production are forbidden propaganda or hint " antibiotic, antibacterial, degerming " and other medical function in its packing, label, description and other relevant publicity materials.Make consumer be hard to tell hand cleanser products so whether biocidal efficacies is arranged.For this reason, we utilize consumer to Sal (NaCl) have sterilization, antiinflammatory, invigorate blood circulation, the common cognition of effect such as antipruritic and skin protection, developed a kind of crystallite salt grain disinfection hand cleanser that contains, do not adding under any sterilization antiseptic situation, reach the antisepsis and sterilization effect, to remedy this kind deficiency of this series products.
Prior art: in personal-care supplies, sodium chloride have thickening, stable, regulate effect such as profit surface tension, be widely used in the products such as shampoo, bath gel, handwashing liquid, cleansing milk, the white toothpaste of salt, mouthwash, water outlet frost.But its content generally is controlled at below 3%, and too high because of sodium chloride content, the surfactant micelle will be by the crosslinked bar-shaped stratiform that transfers to, and viscosity will descend again, make the product viscosity not reach requirement.Application number is in 200510010817.8 patents " a kind of oil-in-water type handwashing liquid and preparation method thereof " application of high-load salt in hand cleanser products to have been arranged, sodium chloride content described in its claims is 9% ~ 34%, but fill a prescription by described in the embodiment, when the salt shot-like particle was arranged in the prepared product, product was prone to solid-liquid layering situation.
Summary of the invention
Goal of the invention:The invention provides a kind of crystallite salt grain disinfection hand cleanser that contains, the clean skin of this product energy deep-pollution-removing, and can have the bactericidal antiphlogistic effect by the effect of Sal (NaCl); Another object of the present invention provides a kind of preparation method of this handwashing liquid.
Technical scheme:A kind of disinfection hand cleanser that contains the crystallite salt particle is made up of the raw material of following mass ratio: salt: 15.0~30.0%; Surfactant: 12.0~25.0%; Wetting agent: 3.0~8.0%; Thickening agent: 0.5~3.0%; Essence: 0.1~0.5%; PH regulator agent: 0.1~2.0%; Surplus is pure water.
Described salt was the minus sieve shape salt of 0.4 mm sieve.
Described surfactant is anion, nonionic or amphoteric ionic surfactant, described anion surfactant is one or more mixture of dodecyl alcohol ether sulphuric acid acid sodium, sodium lauryl sulphate or polyoxyethylene ether sulfosuccinic acid disodium, non-ionic surface active agent is lauroyl diglycollic amide or lauroyl single ethanol amide, and zwitterionic surfactant is one or both mixture of fatty acid distribution of coconut oil CAB or imidazoline.
Described wetting agent is one or more the mixture in silicone oil, tea tree oil, cation pantothenylol or the polyhydric alcohol.
Described thickening agent is the two or more mixture of guar gum, carboxymethyl cellulose, hydroxyethyl-cellulose or acrylic acid polymer.
Described pH regulator agent is citric acid or sodium citrate salt.
Preparation contains the method for the disinfection hand cleanser of crystallite salt particle, and this method comprises the step of following order: add deionized water in the water pot of vacuum homogeneous emulsifying machine, add sodium chloride and stir, making the sodium chloride mass concentration in the deionized water is 2%; Order adds anion surfactant, zwitterionic surfactant and non-ionic surface active agent again, is heated to 60 ~ 70 ℃, the dissolving of 30 ~ 40r/min stirring at low speed; Wetting agent is added in the oil phase pot, add thickening agent, fully stir moistening and disperse; Material in the water pot is evacuated in the mulser homogenizing pot, under 30 ~ 40r/min stirring at low speed, material in the oil phase pot is added again, be heated to 60 ~ 70 ℃ of stirring and dissolving; After the cooling, under the evacuation state, add 13 ~ 28% sodium chloride, open the homogenizing function, set homogenizing rotating speed 1200-1800r/min, open simultaneously and stir speed of agitator 30-40r/min; To go up step gained material and be evacuated in the finished product jar, still aging 24 ~ 48 hours, get product.
Beneficial effect:Effects such as Sal (NaCl) has sterilization, antiinflammatory, invigorates blood circulation, antipruritic and skin protection, its application in handwashing liquid can be given full play to its effect.
The present invention has furtherd investigate the characteristics of handwashing liquid under the high content of salt, in conjunction with the needs of the function of washing one's hands, carries out formulation optimization, finally adopts unique polynary prescription composite, makes the flowability of product close with common handwashing liquid, and the crystallite salt grain that has the energy sense of touch to arrive in the product.Prescription adopts easily degraded surfactant raw material, and to select natural crystalline salt for use be sterilization, antiinflammatory, massage agent, adds functional Safflower Oil again, and the outward appearance of product and serviceability are all good.Often use, can effectively prevent spread of germs and handle inlet etc.
