AI Technical Summary

Technical Problem

Existing laundry compositions face issues with slow dissolution, heat resistance, durability against mechanical impact, and impact resistance during washing and drying processes.

Method used

A solid composition is formulated by combining a water-soluble nonionic surfactant and a water-poorly soluble component in a specific ratio, with a mass% ratio of 90/10 to 40/60, to achieve gradual dissolution, heat resistance, and impact resistance during washing and drying.

Benefits of technology

The composition provides slow dissolution, good heat resistance, and enhanced durability against mechanical impacts during washing and drying, ensuring effective performance in laundry environments.

Abstract

To provide a solid composition for solving such problems under cleaning environment as control of slow solubility while cleaning, heat resistance to heat in cleaning and drying, durability to impact by mechanical force while cleaning, and / or impact resistance (durability) when cleaning and drying and the like.SOLUTION: A solid composition for cleaning treatment includes: (A) a water-soluble nonionic surface active agent having a melting point of 25°C or higher, or a copolymer of polyethylene glycol or polyoxyethylene with polyoxypropylene; (B) a water-soluble constituent having a melting point of 50°C or higher; and (C) a functional constituent, where the mass% ratio (B) / (A) is 90 / 10-40 / 60.SELECTED DRAWING: None
