The present invention is a method for estimating a physical property of an aqueous sample containing a surfactant and water, comprising: adding an oil component and a phase-changing probe to the aqueous sample, and estimating the physical property of the aqueous sample from an amount of the phase-changing probe when a phase structure of the mixture changes.

Method for estimating physical property of aqueous sample

The present invention is a liquid detergent composition for tableware and/or kitchen hard articles containing: (a) a nonionic surfactant with an HLB of 10.5 or less; (b) a surfactant selected from amine oxide-type surfactants, amphoteric surfactants, and nonionic surfactants with an HLB of 11 or more; and (c) an organic solvent with a log Pow of 0 or more and 1.5 or less, wherein a proportion of component (a) in all surfactants is 30 mass % or more and 85 mass % or less, a mass ratio of the content of (c) to the content of (a), (c)/(a), is 1 or more and 10 or less, and a viscosity at 20&#xb0; C. is 20 mPa&#xb7;s or less.

Liquid detergent composition for tableware and/or kitchen hard articles

The present invention is a liquid detergent composition for tableware and/or kitchen hard articles containing: (a) a nonionic surfactant with an HLB of 10.5 or less (provided that (b) is excluded); (b) a glycoside having a hydrocarbon group with 8 or more and 18 or less carbons and a glycoside group with an average degree of condensation of 0.5 or more and 3 or less; and (c) an organic solvent with a logPow of 0 or more and 1.5 or less [hereinafter, referred to as component (c)], wherein the content of (a) in all surfactants is 30 mass % or more and 95 mass % or less, a mass ratio of component (c) to the content of (a), (c)/(a), is 2 or more and 8 or less, and a viscosity at 20&#xb0; C. is 20 mPa&#xb7;s or less.

A hair cosmetic containing Components (A) and (B): where Rrepresents a hydrogen atom or a carboxy group; and Rrepresents a hydrogen atom or a methyl group.

Hair cosmetic

A hair cosmetic comprising the following ingredients (A) and (B): (A) a cationic polymer having a charge density of 5.0 to 7.0 meq/g and (B) an anionic polysaccharide derivative wherein a part of the H atoms of the OH group of a polysaccharide compound having the constituent unit described below are substituted with a &#x2014;(CH)COOgroup (m is an integer of 1 to 5) at an average substitution degree of 0.5 to 2.0 per constituent unit, and wherein optionally a part of the H atoms of the remaining &#x2014;OH groups are substituted with Calkyl groups and/or alkylene groups, wherein the viscosity of the ingredient (B) in a 2 mass % aqueous solution (25&#xb0; C.) is 0.5 to 800 mPa&#xb7;s
