The present invention is directed to ophthalmic compositions containing a gelling amount of a combination of galactomannan polysaccharides and borates. The compositions gel or partially gel upon administration to the eye. The present invention also discloses methods of topical ophthalmic administration of the compositions to the eye.

This invention relates to a preparation method for modified fatty alcohol polyoxyethylene ether. The said method includes carrying out a glucosidation reaction of glucose with fatty alcohol ether in the presence of acid catalyst and under vacuum condition, adding NaOH to pH of 8~9, filtrating and precipitating to remove unreacted sugar to obtain modified alcohol ether glucoside, preparing chloroacetic acid modified ether solution of modified alcohol ether glucoside and chloroacetic acid at a molar ratio of 1~2:1, stirring and adding sodium hydroxide into the remaining modified alcohol ether glucoside, heating to 100-110degreeC under vacuum condition and hydrating for 1~2 hours, cooling and adding chloroacetic acid modified alcohol ether solution, maintaining the reaction temperature at 40~90degreeC, and reacting for 2~4 hours to obtain carboxymethylated modified fatty alcohol polyoxyethylene ether. The method has the advantages of easy operation and low cost.

The invention relates to an environment-friendly cleaning agent containing orange oil and a preparation method of the environment-friendly cleaning agent. The cleaning agent consists of the following ingredients in parts by weight: 20 to 30 parts of orange oil, 30 to 50 parts of lauryl sodium sulfate, 10 to 20 parts of fatty alcohol-polyoxyethylene ether, 10 to 20 parts of alkyl glycoside, 10 to 20 parts of ethanol and 100 parts of deionized water. The cleaning agent provided by the invention is characterized in that the orange oil containing more than 80 percent of limonene is used as major ingredients to be compounded with various kinds of surfactants, the cleaning agent has low surface tension, has fragrance and sterilization effects and can effectively remove organic oil stain withoutcorroding the surface of a cleaned object, and in addition, the orange oil is refined and extracted from natural plant orange peels, so the orange oil is harmless to the environment and the human body health, in addition, the biodegradation can be realized, in addition, non-combustion and nonexplosive performance is realized, the use is very safe, and the cleaning agent can be widely applied to the fields of industry, daily use life, medical care and the like.

The invention discloses an anti-inflammatory and whitening essence milk containing Agrimony grass extract. ~5%, peony seed oil 2~5%, Tremella polysaccharide 2~5%, cetearyl glucoside 2~5%, cetearyl alcohol 3.5~5%, camellia oil modified product 2~5% , Sodium Hyaluronate 0.25-1.2%, Peach Gum Hydrolyzate 2-5%, Sodium Acrylate / Sodium Acryloyl Dimethyl Taurine Copolymer 1-1.5%, Prunus chinensis Essential Oil 0.05-0.5% and deionized water Make up the balance; the anti-inflammatory and whitening essence milk containing Agrimony grass prepared by the invention has good anti-inflammatory and whitening effect on the skin, and has no additives, is safe and non-irritating, and not only has anti-inflammatory and whitening effect compared with the existing anti-inflammatory and whitening products Good, and the production process is simple and the production cost is low.

The invention discloses a cashew nut based amide surfactant and a preparation method thereof. The cashew nut based amide surfactant is prepared by the following steps: (1) carrying out reaction on cashew nut acid and an acylation agent to obtain (2-hydroxy-5-pentadecyl) benzoyl chloride; (2) carrying out reaction on the (2-hydroxy-5-pentadecyl) benzoyl chloride and ethylene oxide, and introducing an ethylene oxide hydrophilic group on hydroxyl to obtain (2-hydroxy ether-5-pentadecyl) benzoyl chloride; and (3) carrying out reaction on the product obtained in the step (2) and diamine to obtain the cashew nut based amide surfactant. The cashew nut based amide surfactant has the action of well lowering the surface tension of a water phase system, does not have cloud points, is excellent in salt resistance, emulsifying performance and detergency ability and can be widely applied to the industry and daily use chemical fields as a detergent, an emulsifier and the like. The preparation method disclosed by the invention is simple in the process, high in the yield and easy to operate.

The invention belongs to the technical field of lubricants, and particularly relates to a high-speed filling line lubricant and a preparation method thereof. The high-speed filling line lubricant comprises the following raw materials in parts by weight: 5-15 parts of trans block polyether, 4-12 parts of alkyl glycoside, 2-10 parts of fatty alcohol ether phosphate, 1-5 parts of disodium ethylene diamine tetraacetate, 1-5 parts of isothiazolinone, 1-8 parts of ethanol and 45-86 parts of water. The high-speed filling line lubricant abandons the conventional aliphatic amine system, uses the transblock polyether as a main lubricant which is compounded with the alkyl glycoside and the fatty alcohol ether phosphate, has excellent anti-blocking performance and lubricating performance, and solvesthe shaking problem during filling on a high-speed line; the high-speed filling line lubricant is compounded at room temperature, and has no peculiar smell in the production process; a preparation technology is simple and easy to operate, low in energy consumption, environment-friendly and pollution-free.
