A: A cleaning and antirust agent, a metal workpiece, and an antirust treatment method therefor. The cleaning and antirust agent comprises the following components in parts by weights (based on 500 parts): 2 parts to 12 parts of anhydrous sodium metasilicate, 3 parts to 10 parts of sodium nitrite, 1 part to 5 parts of n-methyldiethanolamine, 0.1 part to 0.5 parts of alcohol ethoxylate, 2 parts to 10 parts of sodium tripolyphosphate, 3 parts to 15 parts of polyethylene glycol, 0.1 part to 0.5 parts of sodium dodecyl benzene sulfonate, 0.1 part to 0.5 parts of sulfonated castor oil, and the balance water. The cleaning and antirust agent can quickly remove oil from the workpiece and can form a dense polar protective film on a metal surface. The cleaning and antirust agent also has anti-mildew and anti-corrosion properties, can be widely used in anti-corrosion treatment of surfaces in the fine processing of a variety of molds, instruments and parts, can also be used for carrying out antirust treatment between processes before coating, and can maintain the original color of the metal.
B: A dye formulation that will not easily fade consisting of the following components in parts by weight: 20-40 parts of a natural plant dye; 2-5 parts of sodium aliphatic alcohol sulfate; 5-10 parts of polyvinyl alcohol; 3-6 parts of sodium propionate; 5-8 parts of methyl acrylate; 1-3 parts of an acryl resin; 3-6 parts of glacial acetic acid; 2-5 parts of a fluorescer; 5-10 parts of an inorganic antibacterial agent; 0.5-2 parts of a negative ion anti-static agent; and 50-70 parts of deionized water. The dye formulation is filled with an acrylic resin, so that the dyed fabric will not easily fade, and the dye formulation contains a fluorescent agent, so that the fabric is fluorescent in a dark environment, and has a good visual effect.
C: The present invention relates to a shaving cream usable for facial cleansing, the shaving cream usable for facial cleansing consisting of the following components in parts by weight: 10-20 parts of sodium lauroyl glutamate, 10-20 parts of sodium cocoyl glycinate, 4-15 parts of stearic acid, 4-15 parts of coconut oil fatty acid, 2-10 parts of glycerol, 10-20 parts of lauryl hydroxysultaine, 5-10 parts of hydroxyethyl cellulose, 2-10 parts of hyaluronic acid, 2-10 parts of propylene glycol, 10-25 parts of an aloe extract, 5-10 parts of menthol, 1-5 parts of a preservative, and 30-60 parts of deionized water. The shaving cream usable for facial cleaning of the present invention unifies a plurality of functions, namely, cleansing, moisturizing, inflammation elimination, and soothing, and has the advantages of being easy to use and being capable of reducing living costs.
