BACKGROUND OF THE INVENTION
The human hair necessitates cleaning and conditioning frequently. The hair becomes soiled from contact with the atmosphere and from sebum secreted by the skin. Too much sebum makes hair dirty and unattractive. Shampooing hair cleans by removing excess dirt and sebum. Shampooing can leave hair wet, tangled and generally unmanageable. Shampooing can also make hair dry or frizzy. Shampooing hair can also result in a perceived loss of softness.
Thus, there is still a need for shampooing and conditioning compositions that have improved ability to deposit upon the hair, and provide increased sensory performance and increased dry and wet manageability performance.

The term “substituted” as used in relation to another group, for example, a hydrocarbon group, means, unless indicated otherwise, one or more hydrogen atoms in the hydrocarbon group has been replaced with another substituent. Examples of such substituents include, for example, halogen atoms such as chlorine, fluorine, bromine, and iodine； halogen atom containing groups such as chloromethyl, perfluorobutyl, trifluoroethyl, and nonafluorohexyl； oxygen atoms； oxygen atom containing groups such as (meth) acrylic and carboxyl； nitrogen atoms； nitrogen atom containing groups such as amines, amino- functional groups, amido-functional groups, and cyano-functional groups； sulphur atoms； and sulphur atom containing groups such as mercapto groups.
The term “alternatively” indicates a different and distinct embodiment.
The term “comprises” and its variants (comprising, comprised of) are open ended.
The term “consists of” and its variants (consisting of) are closed ended, and denotes the inclusion of only the materials or components or steps as recited except for impurities ordinarily associated therewith.
The term “consists essentially of” and its variants (consisting essentially of) are partially closed ended, and limits inclusion to the specified materials or components or steps and to those that do not materially affect the basic and characteristic (s) of the composition or method.
The term “may” confers a choice.
The articles ‘a’ , ‘an’ , and ‘the’ each refers to one or more, unless otherwise indicated by the context of the specification.
Unless indicated otherwise, alkyl, alkylaryl, aryl and alkenyl groups have the following definitions. An alkyl group means a saturated moiety having 1 to 10 carbon atoms that maybe cyclic or linear or branched. An alkylaryl group means a moiety wherein the alkyl moiety is as defined above and the aryl is a moiety with 6 to 20 carbon atoms that have an aromatic ring. An aryl group means a moietyhaving 6 to 20 carbon atoms that has an aromatic ring. An alkenylgroup means a moietywith an unsaturated double bond and having 2 to 10 carbon atomsthat maybe cyclic or linear or branched.
In one embodiment, the silicone emulsion compositionscomprise water and a silicone oil blend, wherein the blend comprisesa silicone gum, a silicone fluid and an amino-functionalized silicone.
The present inventors surprisingly discovered that amino-functionalized silicones having terminal amino groups and alkoxy groups, particularly terminal amino groups and/or terminal alkoxy groups, exhibit dry and wet sensory improvement in shampoos and conditioners. In one embodiment, the inventors unexpectedly discovered that an amino-functionalized silicone with terminal amino groups and terminal alkoxy groups improved the wet combing, wet and dry smoothness, and wet and dry softness sensory properties of shampoos and conditioners. A skilled person would not have expected any difference in sensory properties and manageability between different silicones having amino and alkoxy groups bonded to the siloxane polymer backone. But the present inventors has unexpectedly discovered that the placement of the amino and alkoxy groups on the siloxane polymer backbone does indeed confer certain advantageous properties. In particular, when placed at a terminal position on the siloxane polymer, amino and/or alkoxy groups provide  improved sensory and manageability properties to hair care compositions compared to compositions lacking amino-functionalized silicones or to compositions having amino and alkoxy groups in non-terminal positions.

Sensory tests
Hair tress samples
Each hair tress has a weight of 6 grams and a length of 25 centimeters and a width of 3.5 centimeters. Each hair tress is made from Asian virgin hair and available from International Hair Importers and Products Inc. located in Glendale, New York, USA.
Cleaning the samples
First, each hair tress was cleaned. Each hair tress was wet under 35℃ to 45℃ tap water for 15 seconds. Then 1.0 gram of 9％ sodium lauryl sulfate (SLS) was applied to each hair tress. The hair tress was rubbed for 30 seconds and then rinsed under 35℃ to 40℃tap water for another 30 seconds. Finally, each hair tress was vertically hung to dry.
Treating the samples
Each cleaned hair tress sample was wet under 35℃ to 40℃ tap water for 15 seconds. Then 1.2 grams of test shampoo was applied to a hair tress. The hair tress was rubbed for 30 seconds and then rinsed under 35℃ to 40℃ tap water for 30 seconds. The hair tress was then hung vertically.
Sensory evaluation
A group of twelve panelists were selected to evaluate the above treated hair tresses.
Wet performance: "smoothness in rinse water" and "wet softness (softness in rinse water) " were evaluated by hand under 35℃ to 40℃ flowing tap water and "ease of wet combing" was evaluated using a comb after hanging the wet hair vertically. Every two hair tresses were evaluated together and the panelists scored the hair tresses for each attribute. The better hair tress received a score of 2 and the other received a score of 1.
Dry performance: The treated hair tresses were left to dry overnight. Then "dry smoothness" and "dry softness (ease to bend the dry hair) " were evaluated by hand and "ease of dry combining" were evaluated with a comb. Each attribute was scored by a panelist according to the same scoring method described above.
In summary, the panelist compared two hair tresses (for example, hair tress A and hair tress B) treated with different test shampoos. If the panelist felt that hair tress A was better than hair tress B for smoothness, combing or softness, then hair tress A scored a 2 and hair tress B scored a 1. After all comparisons were complete, a sum of all the scores for each hair tress was calculated. The final scores were calculated for each hair tress and the higher score the better the performance.
A comparison of sensory testing was performed between commercial benchmark 1, commercial benchmark 2and the exemplary shampoo formulation as described herein. Figure 1 shows a comparison of dry sensory test results between commercial benchmark shampoo 1, commercial benchmark shampoo 2 and an exemplary shampoo according to the present invention. Figure 2 shows a comparison of wet sensory test results between commercial benchmark shampoo 1, commercial benchmark shampoo 2 and a exemplary shampoo according to the present invention. The exemplary shampoo of the present invention when used in a shampoo formulation exhibited better sensory feel compared to the benchmark products. In particular, the exemplary shampoo of the present invention exhibited better wet sensory feel compared to the benchmark products. The benchmark shampoo 1 does not contain any aminosilicone. The benchmark shampoo 2 contains amodimethicone, a hydroxy-terminated aminosilicone.
