Definitions

• the present invention relates to compositions dispensable as foams comprising a water soluble, non-polymeric mineral salt, a select surfactant system, a thickener, and water which upon dispensing provides voluminous and stable foam.
• compositions such as shaving creams, hair mousses, spray foams, foaming lotions and foaming creams are intended to be dispensed or sprayed as foams and applied onto the human skin or hair.
• leave-on foaming cosmetic products One common characteristic desired for these leave-on foaming cosmetic products is a foam having favorable characteristics to the consumer such as voluminous and stable foaming, with smooth and mild touch to the skin and hair.
• Hair mousses Leave-on foaming cosmetic compositions for hair are usually referred to as "mousses", which term will be used in the present invention. Hair mousses were born in Europe in the early 1980s. Hair mousses are fundamentally an aerosol foam, however, non-aerosol foams are also known. The general appeal of hair mousses can be largely attributed to the ease of application and controlled amount of product which are possible from mousse formulations. Hair mousse compositions are generally dispensed by a compressible dispenser or a valve and applied to the user's hand or a specifically designed comb and spread through the hair. Alternatively, hair mousse compositions can be directly applied to the hair by dispensing through nozzles. Hair mousses are formulated for the purpose of styling, setting, and arranging, or for other purposes such as shampooing, conditioning, treating, dyeing, and combinations thereof.
• Performance evaluation with respect to foam compositions vary depending on the purpose and concept of the foam product. For example, in evaluating the performance of a hair mousse, one generally considers properties seen in three major stages; the properties of the foam upon dispensing from the package, the properties of the foam upon applying to the hair, and properties of the end results to the hair. Properties considered upon dispensing include volume of foam and foam expansion speed. It is known that when foam expansion is slow or delayed, "pooling" of the product occurs. Properties considered upon applying to the hair include stability and breakability of the foam, non-soapiness, smoothness, softness, creaminess, and stickiness. Properties considered on the end results to the hair include style control, dry or wet feel of hair, removability, shine, moisturizing, conditioning, anti-static, and brushing.
• such foam products typically contain relatively large amounts of a surface active agent or surfactant (greater than 0.5%) or at lower levels in combination with some polymeric material (e.g., resin).

• the electrolytes (or salts) can form complexes with surfactants which decrease the overall solubility of the surfactant and reduce the surface activity of the surfactant.

• compositions which use thickening agents it is advantageous to first solubilize the thickening agents in water before the addition of the other components and the water soluble salts of the compositions.
• the personal care foam compositions of the present invention are used in a conventional manner for applying personal care products to the hair or skin.
• An effective amount of the composition for treating the hair or skin is applied to the hair or skin, that has preferably been wetted with water, and then leaving the composition on the hair or skin to dry or aiding in the drying process with hot air blow drier devices or heated implements.
• Such effective amounts generally range from about 0.5 g to about 50g, preferably from about 1 g to about 20g.
• Application to the hair or skin typically includes contacting the hair or skin with the composition and working the composition throughout the hair or onto the skin or specifically where the effect is most desired.
• This method for treating the hair or skin comprises the steps of: a) wetting the hair or skin with water, b) applying an effective amount of the personal care composition to the hair or skin, and c) allowing the composition to dr - on hair or skin as the hair or skin dries or is dried with a hot air appliance.
• the personal care compositions of the present invention are easily and readily removed with water.
• Examples 1-10 The personal care foam compositions illustrated in Examples 1-4 illustrate specific embodiments of the personal care compositions of the present invention, but are not intended to be limiting thereof. Other modifications can be undertaken by the skilled artisan without departing from the spirit and scope of this invention. These exemplified embodiments of the personal care compositions of the present invention provide improved personal care and conditioning.
• compositions can be prepared by conventional formulation and mixing techniques.
• Component amounts are listed as weight percents and exclude minor materials such as diluents, filler, and so forth.
• the listed formulations therefore, comprise the listed components and any minor materials associated with such components.
• Examples 1-4 are foam compositions produced upon dispensing or spraying the compositions of the present invention.
• the compositions are formed by combining and mixing the ingredients of each column using conventional technology.
• About 0.5 g to about 50g of the personal care foam composition is applied to the hair and/or skin.
