Embodiment 1

[0024] The preparation method of bioremediation type hand cleansing powder comprises the following steps:

[0025] 1) Preparation of modified starch: Weigh 50.0g of starch, add 50mL of water, adjust to slurry, heat to 20°C, adjust pH to 5 with dilute sodium hydroxide solution, add oxidant (hydrogen peroxide) according to 5% of the amount of starch, keep stirring React for 1 hour, add sodium bisulfite solution accounting for 8% of the amount of oxidant, remove unreacted oxidant, then filter, wash with water, and dry to obtain light yellow to white modified starch;

[0026] 2) Preparation of aloe juice: take 1000g of fresh aloe leaves, clean them, chop them up, squeeze them to obtain aloe juice, and store them at -4°C;

[0027] 3) Preparation of builder: grind Glauber's salt through a 40-mesh sieve, and mix it with the modified starch obtained in the above step 1) in a mass ratio of 3:1 to obtain a builder;

[0028] 4) Get the material by the following mass percentages: 4% of a...

Abstract

The invention relates to a biological restorative powder hand cleaner and a preparation method thereof. The powder hand cleaner consists of 65 percent-80 percent of detergency builder, 1.0 percent-5.0 percent of aloe juice, 5 percent-20 percent of surfactant, 1 percent-10 percent of humectant, 5 percent-20 percent of water and 0.1 percent-1 percent of natural perfume, which are mixed. The water, the humectant, the aloe juice, the surfactant and the natural perfume are mixed and dissolved, and the detergency builder is added into the mixture and evenly stirred, thus acquiring the biological restorative wet powder hand cleaner. The invention has the advantages of 1) wet powder property, water solubility, neutrality, no irritation, capability of eliminating heavy-duty greasy dirt with or without water with remarkable efficiency; 2) that the aloe juice is added, so that injury skin can be restored and the cleaned hands are smooth.3) and that modified starch of renewable resource is adopted as the detergency builder, which is environment friendly.

Description

technical field [0001] The invention relates to a heavy-duty detergent, in particular to a bioremediation type hand cleanser and a preparation method thereof, which can quickly remove oil stains on hands and utensil surfaces under the condition of water or no water. Background technique [0002] Water-free hand washing powder mainly adopts two ways at present: the first way is to adopt sawdust or water-insoluble natural fiber to mix with washing powder, for example Chinese patent communique CN1385510 discloses a kind of hand washing powder, and it comprises washing powder, bagasse powder and Wood flour, the second way is to form surfactant sodium dodecylbenzene sulfonate with sodium carbonate, sodium silicate, etc. For example, Chinese patent publication CN1241625 discloses a kind of hand washing powder, whose ingredients include licorice, peanut , Sodium dodecylbenzenesulfonate, etc. The above two hand washing powders are alkaline formulas, which have a certain stimulating...
