Composition capable of controlling release through ion concentration and preparation method thereof

Abstract

The invention discloses a composition capable of controlling release through ion concentration, the composition comprises gel particles and a dispersion system, and the gel particles comprise a matrixand a particle core; the matrix is a gel layer, and the matrix at least comprises a polyhydroxy polymer; the dispersion system comprises a water-soluble metal salt and water, and the total mass of metal ions in the metal salt accounts for 0.05-5% of the total mass of the dispersion system. According to the composition, coating is formed through a matrix, so that different components are isolatedfrom each other, and coexist stably for a long time; and through concentration control, the matrix can release all the components into the dispersion system. The invention also discloses a preparationmethod and a use method of the composition capable of controlling release through ion concentration.

Description

technical field [0001] The invention belongs to the field of controlled-release compositions, in particular to a composition capable of controlling release through ion concentration and a preparation method thereof. Background technique [0002] With the development of technology, people have found that more and more raw materials can be applied to cleaning and washing. Many raw materials can give detergents other functions besides stain removal, such as long-lasting fragrance, bleaching, softness, adsorption of dust, and adsorption of heavy metals. Wait. As people gradually increase the "multi-functional" requirements for this type of cleaning and detergent, technicians need to combine a variety of raw materials with different functions into one product to become a multi-functional product, so that users can clean in one simple cleaning job. , to achieve multiple functions. However, when the dispersion system of this type of product is in liquid state, all components are ...

AI Technical Summary

Problems solved by technology

However, when the dispersion system of this type of product is in liquid state, all components are in direct contact during storage, especially when applied to some insoluble components, it is easy to cause compatibility conflicts between raw materials, resulting in Adsorption or chemical reaction, and then precipitation, stratification, discoloration, thickening and thinning, etc., will affect the performance of the product

[0003] At present, a common solution is to adjust the content of raw materials, reduce the amount of certain ingredients or increase the amount of stabilizers, but this method will weaken part of the performance of the product or increase the production cost

[0004] Another way to deal with it is to screen various raw materials and select compatible combinations to make products. However, this screening process requires long-term and large-scale experiments, and constantly adjusts and tests various combinations to obtain stable products. Lead to low efficiency of new product development
