Problems solved by technology

[0002] Usually the process of producing soap is to directly saponify the mixed animal and vegetable oils, and then add synthetic industrial surfactants to produce soap powder and soap liquid. The process is long, the process is complicated, the cost is high, there are no natural ingredients, and the efficacy is low. Synthetic soap powder and soap liquid have high pH and are irritating to the skin.

Embodiment Construction

[0014] Recipe one

[0015] 100 parts of soybean oil feet, 25 parts of watermelon peel extract, 22 parts of 50% dilute sulfuric acid, 25 parts of caustic soda, 6 parts of 95% ethanol, 15 parts of industrial surfactants, 15 parts of N-acyl amino acids, 10 parts of sodium carbonate Parts, 40 parts deionized water.

[0016] Production method: add soybean oil feet, 50% dilute sulfuric acid and deionized water into the acidification kettle according to the formula ratio, stir and heat to acidify for 4-5 hours, control the temperature at 95℃-98℃, stop heating, stir and separate, let go of the bottom layer Wash the aqueous solution with 90-95℃ water three times, transfer it into the saponification kettle and add watermelon peel extract and caustic soda in proportion, saponify at 75℃-80℃ for 3-4 hours, add 95% ethanol in proportion and continue Stir, then add the industrial surfactant, N-acyl amino acid and sodium carbonate in proportion to mix evenly and fill the mold while it is hot to m...

Abstract

The present invention is the production process of soybean oil residue-water melon soap. During the production, soybean oil residue, 50 % concentration sulfuric acid solution and deionized water in certain proportion are heated to acidify for 4-5 hr at 95-98 deg.c inside an acidifying reactor before quiescence, discharging bottom water solution and thrice washing the acidified product with clearwater at 90-95 deg.c; the acidified product is then mixed with water melon peel extracting liquid and sodium hydroxide to produce saponification at 75-80 deg.c for 3-4 hr in a saponifying reactor, ethanol is added under stirring, and industrial surfactant, N-acyl amino acid and sodium carbonate are added under stirring with the hot product being molded as the water melon soap product. The present invention utilizes waste to produce soap and has low cost, simple production process and other features.

Description

1. Technical field [0001] The invention relates to a daily chemical product, in particular to a production method of soybean oil foot watermelon soap. 2. Technical background [0002] The usual soap production process is to directly saponify animal and plant mixed oils, and then add synthetic industrial surfactants to produce soap powder and soap liquid. The soap produced by the prior art has good detergency, but the disadvantage is the treatment of animal and vegetable oils. Long working procedure, complicated process, high cost, no natural ingredients, low efficacy and other disadvantages. Synthetic soap powder and liquid soap have high PH and are irritating to the skin. 3. Summary of the invention [0003] The purpose of the present invention is to provide a production method for producing soybean oil foot watermelon soap with simple process, easy purchase of raw materials, low cost, and using leftovers of agricultural and sideline products as raw materials. The method of the...
