Embodiment Construction

[0006] While the specification concludes with particularity and distinct claim for the invention, it is believed that the invention will be better understood from the following description.

[0007] All percentages, parts and ratios are based on the total weight of the compositions of the present invention, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include solvents or by-products that may be included in commercially available materials, unless otherwise specified. When more than one composition is used during a treatment, the total weight is considered to be the total weight of all compositions applied to the hair simultaneously (ie the weight present "on the head") unless otherwise indicated. Herein, the term "percent by weight" may be expressed as "% by weight".

[0008] As used herein, the term "hair" to be treated may be "living", ie on a living body, or may be "inanimate", ie a ...

Abstract

Described herein is a method of increasing the uptake and lastingness of hair care benefit agents. The method includes applying to the hair a hair care composition including one or more hair health compounds, and rinsing the hair with water. The one or more hair health compounds each include a benefit agent, one or two permanent cations, and one to four incipient cations, and a hydrophobe that maybe used to attach the benefit agent to the incipient cation. The one to four incipient cations are pendant to the core structure and are neutral. The one or more hair health compounds enter the hairshaft after the hair care composition is applied to the hair. The composition has a pH of from about 3.5 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6.

Description

technical field [0001] The present invention provides a method of imparting long-lasting, increased benefits to hair with one or more washable hair health compounds. These compounds each have from one to four ionizable amine groups and a hydrophobic group which facilitates attraction and diffusion to the hair fibre. The ionizable amine groups attached to the benefit agent via a hydrophobic linker allow better penetration of the hair health compounds into the hair fiber rather than retaining them on the surface of the fiber. Background technique [0002] While leave-on treatments can use long dwell times to deliver benefit agents to the hair, generally, more commonly used product hair care products are The fibers deliver meaningful concentrations of benefit agents. This generally means that a high concentration is required (relative to the amount required to be delivered) or when lower concentrations are used, only a small amount can be delivered to the hair. Additionally,...
