ABSTRACT:
TECHNICAL FIELD
This invention relates to liquid soap formulations constructed for being. dispensed as a foam product and, more particularly, to improved liquid formulations capable of being dispensed as a foam product for.use in a wide variety of alternate applications, including for washing, shaving and use for medicinal or medical purposes.
BACKGROUND ART
Recently, the use of liquid soap has become extremely popular, with the ease and convenience provided by such products being appreciated by many individuals. However, in spite of the popularity of liquid soap, no widely useable, multi-purpose, effective liquid soap product has been developed which is capable of being dispensed as a foam mousse product to provide consumers with the substantially increased benefits inherent in a foam mousse and be useable for shaving and medical applications.
By providing an improved liquid soap formulation which are capable of being dispensed from a desired container as a foam mousse, consumers enjoy a wide variety of substantially enhanced benefits. In using any soap product, whether liquid or solid, the consumer is required to place a desired amount of the soap product in one's hands or on the area to be washed, and then vigorously rub the soap product in the hands or target site in order to develop a lather or foam, in order to achieve the desired cleaning. However, by dispensing the improved liquid soap product as a foam mousse directly from the container, ease of application and use of the product is enhanced.
A further benefit achieved from dispensing liquid soap as a foam mousse is a substantial reduction in the quantity of the product that must be dispensed at any particular time for any desired purpose. The foam mousse is produced by intermixing air into the soap formulations to produce the foam mousse product being dispensed. As a result, substantially less product is consumed at any particular time, thereby saving the consumer a substantial expense by controlling the amount of product being dispensed and thereby preventing unwanted wasting of product.
Another area in which consumer needs and desires have not been satisfied is in the area of shaving for both men and women. Although various shaving creams and foams have been created in attempting to provide a smooth, comfortable shave to men and women, manufacturers have typically resorted to producing shaving foams which rely upon aerosols or other foam producing gases.
Although these typical prior art products produce foams of various thicknesses and densities, these prior art products are incapable of achieving a product which is completely devoid of aerosols or other foaming agents or ingredients. Furthermore, such prior art products are bulky and require large containers or dispensers, as well as special pressurized gas holding systems, in order to accommodate the required aerosols for producing the foam.
Another area in which no effective prior art products have been developed is the medical area wherein numerous applications for a foam soap product exist with no solution being provided. Furthermore, in most of these areas, medicinal or therapeutic ingredients incorporated into the foam soap product would greatly enhance their use. However, no prior art product has been made which is capable of meeting this long-felt need. Some specific uses for a product of this nature are diseases and irritations in the vagina and/or the rectum where numerous problems exist that have been largely ignored. Although a long felt need has existed in these areas for safe and effective products, no prior art product has been achieved which is readily available and highly effective in treating or eliminating such diseases and problems.
Therefore, it is a principal object of the present invention to provide a multi-purpose, highly effective, liquid foam soap delivery system which is capable of being used in a wide variety of alternate product formulations and delivery systems.
A further object of the present invention is to provide a multi-purpose, highly effective, liquid foam soap delivery system having the characteristic features described above, which is capable of being dispensed from non-aerosol containers and produces a thick, rich, dense, foam mousse.
A further object of the present invention is to provide a multi-purpose, highly effective, liquid foam soap delivery system having the characteristic features described above, which incorporates an effective amount of a medical or medicinal ingredient for further enhancing the use and application of the present invention in a wide variety of alternate purposes.
Other and more specific objects will in part be obvious and will in part appear hereinafter.
DETAILED DISCLOSURE
By employing the present invention, all of the difficulties and drawbacks of the prior art have been overcome, and a highly effective, multi-purpose, universally applicable improved liquid based foam soap delivery system is achieved. In addition to attaining a universally useable, liquid based foam soap product, the present invention achieves an improved liquid based foam soap system that can be employed for all normal washing, as well as for shaving and for use as a device in treating a wide variety of medical conditions and problems.
The principal feature of-the present invention is the attainment of an improved liquid based soap formulation which is capable of being employed with and dispensed from non-aerosol, foam-producing containers in a consistent and repeatable manner. Typically, conventional liquid soap formulations are incapable of repeatedly passing through the foam producing dispensing heads associated with foam containers/dispensers. Due to the inherent nature of conventional liquid soap, the fine mesh screens employed with foam heads are quickly clogged, preventing the effective, reliable use of conventional liquid soap in this manner.
With the present invention, a unique improved liquid soap formulation is realized which eliminates the prior art inabilities and provides a formulation which is effectively dispensed from foam producing dispensing heads in a consistent, reliable and repeatable manner, free from clogging failures. In accordance with the present invention, the principal ingredients are a mixture of surfactants, which inherently possess foam enhancing or foam producing qualities, and water with the quantity of water employed representing a critical factor. In order to achieve a formulation which is capable of being dispensed as a foam mousse, the total water employed must range between about 40% and 80% by weight of the total weight of the entire composition.
An additional ingredient which is preferably incorporated into the liquid foaming soap formulations of the present invention comprises one or more therapeutic agents. As is more fully detailed below, by incorporating a therapeutic agent, the present invention achieves a unique, universally employable, foam mousse product which is capable of being used in a wide-variety of alternate applications for a wide variety of alternate purposes. In this regard, the presence of a therapeutic agent in the liquid foam soap formulation substantially enhances the usability and applicability of the liquid foam soap product, while also providing substantially enhanced beneficial results in areas where beneficial results have not been attainable.
In accordance with the present invention, it has been found that the quantity of the surfactants employed in the composition preferably ranges between about 5% and 70% by weight based upon the total weight of the entire composition.
The final ingredient incorporated into the improved liquid based foaming soap composition of the present invention is one or more therapeutic agents, used to achieve a desired, targeted or multi-functional result. In employing a therapeutic agent, the effective amount needed to achieve the desired result is employed.
In Table I, the overall composition discussed above is fully detailed. This composition represents the preferred formulation for achieving the goals of the present inventi
