The invention discloses a neutral cleaning agent for water-in-oil cosmetics and a preparation method of the neutral cleaning agent, belonging to the field of cleaning supplies. In the components of the neutral cleaning agent disclosed by the invention, a specific nonionic surfactant and a specific ampholytic surfactant jointly exert permeation, emulsification and stripping effects on the water-in-oil cosmetics, so the effect of effectively treating the residual water-in-oil cosmetics in production equipment is achieved; the addition of a penetrant can further assist the surfactants in improving cleaning efficiency; and the produced neutral cleaning agent does not contain VOC substances, nonyl phenol or other heavy metal toxic substances, is safe and environment-friendly, is neutral, and does not cause corrosion damage to clean equipment. The invention also provides the preparation method of the neutral cleaning agent. The preparation method has the advantages of simple operation steps, low requirements on production equipment, and realization of industrial large-scale production. The invention further provides application of the neutral cleaning agent to instrument and equipment cleaning.
Description
technical field [0001] The invention relates to the field of cleaning supplies, in particular to a neutral cleaning agent for water-in-oil cosmetics and a preparation method thereof. Background technique [0002] Silicone oil has the advantages of small temperature viscosity coefficient, high and low temperature resistance, high oxidation resistance, non-volatile, good insulation and low surface tension, non-corrosive to metal, non-toxic, and insoluble in water, methanol and other solvents. Its comprehensive performance is excellent. Now it is widely used in various industries. In the cosmetics industry, various products, especially water-in-oil make-up products, are mainly made of a variety of silicone oils. However, cleaning equipment for the production of water-in-oil cosmetics has always been a problem for major companies. At present, the methods adopted in the existing technology are mainly to dismantle the production equipment and wipe it, or put it in a heating pool...
