13. A process for making a solid foaming composition comprising blending a solid surfactant, a chelator, a preservative, a pH buffer, an anticaking agent and an emollient.

14. The process of claim 13 comprising milling the solid surfactant prior to said blending.

15. The process of claim 13 comprising: Step A: combining the chelator, the buffer and the preservative to produce a first blend and Step B: blending the first blend with the solid surfactant to form a second blend.

16. The process of claim 15 comprising: Step C: combining the second blend with at least a portion of the anticaking agent to form a third blend.

17. The process of claim 16 wherein Step C comprises: combining an essential oil and a compatibiliser to form an oil-compatibiliser mixture and adding the oil-compatibiliser mixture to the anticaking agent under agitation, so as to form a fourth blend, and combining the second blend and the fourth blend so as to form the third blend.

18. The process of claim 16 comprising: Step D: combining the emollient with the third blend so as to form the composition.

19. The process of claim 18 wherein Step D comprises: combining the emollient with a portion of the anticaking agent to form a fifth blend; and adding the fifth blend to the third blend so as to form the composition.

20. The process of claim 15 wherein step A comprises: combining the chelator, the buffer, the preservative and a solid skin conditioner so as to produce the first blend.

21. A process for making a liquid foaming composition, said process comprising: combining the composition of claim 1 with water in a ratio of 1 part by weight of said composition to from 20 to 50 parts by weight of water, said water being at a temperature of between about 30 and about 90° C.; and agitating the resulting mixture for a time of between about 10 and 60 seconds.

Industrial Application

[0070] The solid composition may be combined with water so as to produce a foaming liquid hand wash, body wash or similar product.

Interpretation

Markush Groups

[0071] Where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognise that the invention is also thereby described in terms of any individual member or subgroup of members of the Markush group.

Chronological Sequence

[0072] For the purpose of this specification, where method steps are described in sequence, the sequence does not necessarily mean that the steps are to be carried out in chronological order in that sequence, unless there is no other logical manner of interpreting the sequence or unless that specific order is indicated.

Embodiments

[0073] Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure, in one or more embodiments.

[0074] Similarly it should be appreciated that in the above description of example embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of this invention.

[0075] Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination.

Different Instances of Objects

[0076] As used herein, unless otherwise specified the use of the ordinal adjectives “first”, “second”, “third”, etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.

Specific Details

[0077] In the description provided herein, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Terminology

[0078] As used herein the term “and/or” means “and” or “or”, or both.

[0079] As used herein “(s)” following a noun means the plural and/or singular forms of the noun.

[0080] As used herein, the term “may” encompasses both the stated proposition and its opposite. Thus, for example, the phrase “A may be B” envisages both “A is B” and “A is not B” unless the specific context indicates otherwise.

Comprising, Including, Consisting Essential of

[0081] In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” are used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.

[0082] Any one of the terms: including or which includes or that includes as used herein is also an open term that also means including at least the elements/features that follow the term, but not excluding others. Thus, including is synonymous with and means comprising.

[0083] The term “consisting essential of”, or variations thereof, is used to indicate that the stated integers are the only ones intentionally added and that other integers which may be present to do not substantially affect the working of the invention. Thus for example, “A consists essentially of B and C” requires that B and C be present and that no further components are added intentionally. It does not preclude the presence in A of, for example, impurities present in B and/or C, or entrained air incorporated during mixing of B and C.

Scope of Invention

[0084] Thus, while there has been described what are believed to be the preferred embodiments of the invention, those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within the scope of the invention. For example, any formulas given above are merely representative of procedures that may be used. Steps may be added or deleted to methods described within the scope of the present invention.

[0085] Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.

INDUSTRIAL APPLICABILITY

[0086] It is apparent from the above, that the compositions described are applicable to the personal care industry.
