Abstract

The present invention relates to detergent compositions containing a blend of selected isoprenoid-based surfactants in a defined ratio and methods of making and using the same. Moreover, a detergent composition comprising a cationic surfactant system comprising 0.01 to 25% of a blend of one or more polyalkyl isoprenoid-based surfactant is disclosed.

Description

technical field [0001] The present invention relates to detergent compositions comprising selected blends of isoprenoid-based surfactants and methods of making and using them. Background technique [0002] Most conventional detergent compositions contain a mixture of various detersive surfactant components. Commonly encountered surfactant components include various anionic surfactants, especially alkylbenzenesulfonates, alkylsulfates, alkylalkoxysulfates, and various nonionic surfactants, such as alkyl Ethoxylates and Alkylphenol Ethoxylates. Surfactants used as detergent ingredients have been found to be capable of removing a wide variety of soils and stains. There has been a consistent effort by detergent manufacturers to improve the soil removal performance of detergent compositions by providing new and improved surfactants. Challenges facing detergent manufacturers today include cooler wash temperatures, less effective builders, liquid or powder products without calci...
