Problems solved by technology

[0002] At present, ordinary starch (such as corn starch), as a natural and environmentally friendly green raw material, can be widely used in food, papermaking, textile, daily chemical and pharmaceutical fields. Only by improving its molecular structure by physical or chemical methods and strengthening its characteristic indicators and application performance can it be suitable for some specific or high-end applications, such as the field of daily skin care products, including talcum powder, compact powder, face cream, etc. This field requires materials with Excellent oil-in-water emulsion stability system, smooth powder characteristics and efficient moisturizing performance, and most of the production processes of daily skin care products use cold materials to mix evenly at high speed, and the requirements for the microbial indicators of materials are relatively high during the production operation process, so Ordinary corn starch is difficult to meet these requirements

Abstract

The invention discloses a production method for alkenyl succinic acid aluminum starch applied to the field of skin care products for daily use. The method includes the following steps: (1) mixing corn starch and water evenly in a reaction tank to obtain starch milk; (2) adjusting pH of the starch milk to alkalinity; (3) adding octenyl succinic anhydride into the reaction tank to undergo esterification; (4) adding aluminum sulfate into the reaction tank to continue reacting; (5) adjusting the pH of the starch milk obtained through the reaction in the step (4) to faintly acid or neutral; (6) after the pH of the starch milk in the step (5) is stable, washing through a swirler, entering a refine milk tank after washing, and leading in ozone to sterilize; and (7) dehydrating, drying, sieving and packaging the sterilized starch milk sequentially to obtain alkenyl succinic acid aluminum starch. The corn starch is used as the main raw material to produce the alkenyl succinic acid aluminum starch, hydrophobicity, dispersibility and emulsion stability of the alkenyl succinic acid aluminum starch are good, total quantity of bacterial colony is low, and the alkenyl succinic acid aluminum starch can be applied to the field of skin care products for daily use.

Description

technical field [0001] The invention relates to a method for producing starch aluminum octenyl succinate used in the field of daily skin care products. The starch produced by the method has excellent emulsification and dispersibility, and belongs to the technical field of modified starch production. Background technique [0002] At present, ordinary starch (such as corn starch), as a natural and environmentally friendly green raw material, can be widely used in food, papermaking, textile, daily chemical and pharmaceutical fields. Only by improving its molecular structure by physical or chemical methods and strengthening its characteristic indicators and application performance can it be suitable for some specific or high-end applications, such as the field of daily skin care products, including talcum powder, compact powder, face cream, etc. This field requires materials with Excellent oil-in-water emulsion stability system, smooth powder characteristics and efficient moistu...
