Definitions

• the invention relates to a shower gel formulation.
• shower gel formulations which are mild to the skin are well known in the art.
• Such a formulation may optionally contain skin feel agents, such as cationic polymers.
• skin feel agents such as cationic polymers.
• anionic surfactants when one desires to suspend particulates and/or beads in the formulation, frequently substantial quantities of anionic surfactants have been incorporated, and provide clear solutions. Unfortunately, the addition of such anionic surfactants diminishes the mildness of the shower gel formulation.
• U.S. Patent No. 5,656,257 discloses an anionic shampoo and conditioning composition comprising an oily conditioning agent, a shampooing agent, and an acrylate copolymer, a cationic conditioning agent and water.
• the acrylate copolymer is used to suspend the anionic shampooing and cationic conditioning agent and prevent it then from inactivating one another.
• U.S. Patent No. 5,656,257 does not, however, disclose a clear, mild cleansing composition containing a combination of surfactant types, which is capable of suspending beads or other insoluble particulates or gas bubbles.
• the present invention comprises a shower gel formulation having a clear appearance and which suspends beads (e.g. agar/TiO2/sunflower oil beads), insoluble particles and gas bubbles while having one or more acrylate copolymers, a betaine or other amphoteric surfactant and a cationic polymer (e.g. guar) present in the formulation.

• anionic acrylates i.e. Aculyn type acrylates (available from ISP)
• anionic polymers are generally considered to be incompatible with cationic charged ingredients.
• polymeric cationics, as well as some large, bulky quaternary materials, can possibly be incorporated in formulations containing such acrylates.
• the optimum order of addition in these instances generally requires the acrylate to be neutralised with a base prior to the addition of any cationics.
• Clarity or transparency is herein defined as having a turbidity less than or equal to 105 NTU (Nephelometric Turbidity Units).
• amphoteric surfactants such as betaine (which is also cationic in nature and not a true amphoteric), may be optionally added to the inventive formulation in the range of 0.01 - 15 weight percent, preferably 1-10 weight percent to increase mildness without creating noticeable haziness.
• Prior art shower gels that suspend beads or particulate matter are primarily composed of anionic surfactant and structurant which in most cases are harsher than the inventive formula.
• the present invention provides an aqueous, clear shower gel which is capable of suspension, comprising:

(Lombard, IL); and acrylates copolymer obtainable as either Aculyn® 33 from International Specialty Products Corp. or as Polymer EX-518® from BF Goodrich Corp.
• inventive compositions may be used for the cleansing of the user's skin and hair and is applied to a surface (e.g. a skin surface) via topical applications to release or deposit an effective amount of the transparent composition to perform the desired cleansing function.
• the frequency of topical application can vary widely, depending on the user's need. With respect to personal application to the skin, such application can range from about once per day to about four times per day, preferably from about twice a day to about three times a day.
