AI Technical Summary

Benefits of technology

The patent describes a fibrous web structure that can be dissolved. It is made from a composition containing a surfactant, a water-soluble polymer, and a plasticizer. The ratio of polymer to active agent in the fiber is important - it should be 3.5 or lower. The technical effect of this invention is that it provides a better fibrous web structure for dissolvable articles that can be easily dissolved in water.

Problems solved by technology

While widely used, liquid products have disadvantages in terms of packaging, storage, transportation, and convenience of use.
Liquid consumer products typically are sold in bottles which add significant cost as well as packaging waste, much of which ends up in land-fills.
However, the inclusion of active agents can adversely affect the extensional rheology properties of the water soluble polymer composition and the ability to produce fibers.
However, including high levels of ionic surfactants (anionic surfactants, amphoteric surfactants, zwitterionic surfactants, cationic surfactants) can be difficult as they may result in generally non-cohesive liquid / paste-like phase structures (worm-like micelle, liquid crystal, and hexagonal phases) even at high concentrations.

Abstract

The personal care compositions of the present invention are in the form of an Article comprising a dissolvable fibrous web structure. The fibers of the dissolvable fibrous web structure comprise a surfactant; a water soluble polymeric structurant; and a plasticizer. Additionally the ratio of the water soluble water soluble polymeric structurant to the active agent in the fiber is 3.5 or less.

Description

FIELD OF THE INVENTION[0001]Described herein, is a personal care, oral care, health care, and household care composition that delivers active agents onto hair, hair follicles, skin, teeth, the oral cavity, fabric and hard surfaces in the form of an article that is a dissolvable fibrous web structure.BACKGROUND OF THE INVENTION[0002]A majority of consumer products in the market today are sold as liquid products. While widely used, liquid products have disadvantages in terms of packaging, storage, transportation, and convenience of use.[0003]Liquid consumer products typically are sold in bottles which add significant cost as well as packaging waste, much of which ends up in land-fills.[0004]Traditionally delivery of active agents from multicomponent fibers are the result of fibers comprised of typical thermoplastic polymers, such as polyolefins, which are insoluble in water, i.e., the fiber does not fully dissolve. Furthermore, the active agent component of such fibers traditionally i...
