Benefits of technology

The patent text describes two different cleansing compositions that are meant to be sulfate-free. The first composition includes an anionic surfactant, an amphoteric surfactant, cationic polymer, inorganic salts, an aqueous carrier, and no sulfate based surfactant. The second composition includes an anionic surfactant, an amino acid based surfactant, cationic polymer, inorganic salts, an aqueous carrier, and no sulfate based surfactant. These compositions are meant to be effective at cleaning without causing excessive skin or eye irritation.

Problems solved by technology

However, it can be difficult to use non-sulfate based surfactants in liquid shampoos because it can be difficult to formulate a composition that has acceptable lather volume, cleansing, conditioning benefit, stability.
One common problem is that using certain cationic conditioning polymers in products that are substantially free of sulfate containing surfactants can result in instability.
Presence of coacervate in the cleaning compositions can lead to separation upon storage, causing inconsistent performance in use.

Abstract

Personal cleansing compositions having an anionic surfactant, cationic deposition polymer, a level of inorganic salt of from about 0 to about 1 wt %, and an aqueous carrier. The composition is substantially free of sulfate containing surfactants. The composition can further comprise amphoteric surfactants. The composition remains phase stable, and minimizes coacervate formulation until after dilution with water.

Description

FIELD OF THE INVENTION[0001]The present disclosure generally relates to stable personal cleansing compositions which are formulated with anionic surfactants substantially free from sulfates, amphoteric or amphoteric surfactants, cationic deposition polymers and a low level of inorganic salt.BACKGROUND OF THE INVENTION[0002]Most commercial cleansing compositions, such as shampoo compositions, comprise sulfate-based surfactant systems because of their effectiveness in generating high lather volume and good lather stability and cleaning. However, some consumers may prefer a shampoo composition that is substantially free of sulfate-based surfactant systems. In addition, sulfate free shampoos users prefer high conditioning shampoos because higher conditioning shampoos feel less stripping to the hair. Conditioning shampoos based on sulfate based surfactant systems typically contain cationic conditioning polymers to form coacervate with the sulfate based surfactant system during use. Howev...
