    • A light duty microemulsion liquid detergent composition, useful for removing greasy soils from surfaces with both neat and dilute forms of the detergent composition, includes a moderately water soluble complex of anionic and cationic surfactants, in which complex the anionic and cationic moieties are in essentially equivalent or equimolar proportions, an anionic detergent, a co-surfactant, an organic solvent and water. Preferably, the complex component is one in which the anionic and cationic moieties include hydro­philic portions or substituents, in addition to the complex forming portions thereof, the anionic detergent is a mixture of higher paraffin sulphonate and higher alkyl polyoxyethylene sulphate, the co-surfactant is a polypropylene glycol ether, a poly-lower alkylene glycol lower alkyl ether or a poly-lower alkylene glycol lower alkanoyl ester, and the organic solvent is a non-polar oil, such as an isoparaffin, or an oil having polar properties, such as a lower fatty acid ester or a lower fatty alcohol ester. Also within the invention are the described complex, preferably one of equimolar proportions of sodium C₁₂₋₁₄ alkyl diethoxy ether sulphate and C₁₂₋₁₄ alkyl-bis(2-hydroxyethyl) methylammonium halide, and processes for manufacturing the liquid detergent composition and for removing grease from laundry and hard surfaces by use of such a liquid detergent composition, especially in neat form, in which latter process significantly improved cleaning results, compared to that obtained when using control detergent compositions.

    • A high-concentration pearling agent dispersion is disclosed. The dispersion comprises as essential components, at a specific proportion, a fatty acid glycolic ester of formula (I):


      Y-O-(CH₂CH₂O) m - -R₁      (I)
      wherein R₁ represents a linear or branched, saturated or unsaturated hydrocarbon group of a C₁₃₋₂₁ carbon atom content, Y represents a hydrogen atom or a

      - -R₁ group, m indicates a value of 1 to 3, which is the average number of ethylene oxide group addition moles; an alkylsulfosuccinate or a polyoxyalkylenealkylsulfosuccinate of formula (II):
      wherein R₂ represents a linear or branched alkyl group of a C₈₋₂₀ carbon atom content, R₃ represents a hydrogen atom or a methyl group, M represents an alkali metal, an alkali earth metal, an ammonium ion, an alkyl group-substituted ammonium with the alkyl group having a C₁₋₃ carbon atom content, or a hydroxy alkyl group-substituted ammonium with the hydroxy alkyl group having a C₂₋₃ carbon atom content, n indicates a value of 0 to 8, which is the average number of addition moles; a fatty acid dialkanol amide of formula (III):
      wherein R₄ represents a linear or branched, saturated or unsaturated hydrocarbon group of a C₇₋₁₇ carbon atom content, and R₅ and R₆ independently represent a group -C₂H₄ or -C₃H₆; and water. The pearling agent dispersion comprises uniformly shaped crystals, has a low viscosity, and exhibits a superior stability at high and low temperatures.
