Abstract

An aqueous detergent composition having a physical form selected from the group consisting of liquids, pourable gels and non-pourable gels, said composition comprising surfactant and water, which composition is structured with a lamellar phase formed of at least some of the surfactant and at least some of the water, the composition being substantially clear at 25 DEG C.

Description

field of invention [0001] The present invention relates to aqueous liquid detergent compositions which contain sufficient detergent active material and, optionally, sufficient dissolved electrolyte to produce a lamellar structure. Background of the invention [0002] Aqueous liquid detergent compositions can generally be structured in one of two different ways to impart consumer preferred flow characteristics and / or cloudy appearance and / or suspended particulate solids, such as detergency builders or abrasive particles. [0003] The first approach employs "external structurants," such as glue or polymeric thickeners. The second approach is to form an "internal structure" of lamellar phases formed by surfactants and water, which usually contain dissolved electrolytes. [0004] The lamellar phase is a specific class of surfactant structures known inter alia from various references, such as H.A. Barnes, 'Detergents', Ch.2, K. Walters (Ed), Rheometrics: Industr...
