Composition for solid washing agent, and solid washing agent

摘要

A solid washing agent that is hard even in a high-temperature, high-humidity atmosphere or in a similar environment and that can prevent melting away and stickiness is provided.;A composition for a solid washing agent containing an N-long chain acyl acidic amino acid salt as a component of an ingredient wherein the salt for the N-long chain acyl acidic amino acid salt is composed of an alkali metal salt and an ethanolamine salt, the molar ratio of the alkali metal salt to the ethanolamine salt is 10:90 to 75:25, the degree of neutralization is 1.5 to 2.0 eq, and an alkyl-modified silicone represented by formula (I) below is blended as an ingredient, and a solid washing agent formed from the composition.

1. A composition for a solid washing agent that is highly foaming yet hard even in a high-temperature, high humidity environment, comprising:
an N-long chain acyl acidic amino acid salt as a component of an ingredient,
a salt for the N-long chain acyl acidic amino acid salt comprising an alkali metal salt and an ethanolamine salt,a molar ratio of the alkali metal salt to the ethanolamine salt being 10:90 to 75:25,a degree of neutralization being 1.5 to 2.0 eq, and an alkyl-modified silicone represented by formula (I) below as an ingredient:wherein R represents an alkyl or alkenyl group having 8 to 18, and a and b each represent an integer of 0 to 3;
wherein the composition has a maximum extent of melting caused by rubbing of 70 g/100 cm2 as determined according to JIS K-3304 and has foaming properties of at least 1950 ml as determined by stirring 400 ml of 1 wt % in aqueous 70 ppm calcium chloride at 40 degrees Centigrade for 60 seconds.
