Description

COMPOSITION FOR ANTIBACTERIAL LIQUID PERSONAL CLEANING THREE IN ONE WITH GENERATION OF ULTRA SOFT FOAM BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to mild antibacterial compositions for personal cleansing in liquid form. More specifically, the present invention relates to soft, foaming compositions, especially those that are useful for application to the body, face and hands. BACKGROUND OF THE INVENTION The cleaning of the skin, carried out with active surface cleaning preparations, has become a point of great interest. Many people wash and rub their skin with different active surface preparations several times a day. Cleaners in liquid form are highly preferred, especially for use in the body, due to the convenience and to not dirty the toilets and bathrooms in general. The antibacterial cleansers for personal cleansing are preferred because they kill germs. Gentle cleansers for personal cleansing are those that are desired to minimize skin irritation, dryness, etc. It would be very desirable, a personal cleansing product, having these three preferred characteristics. Cleansers for the skin, should clean the skin gently, cause little or no irritation, without drying the skin after frequent use. Certain synthetic surfactants are particularly mild. However, the main drawback of soft synthetic surfactant systems in liquid form is that when they are formulated to cleanse the skin, they have poor foam generation. Compared with soap bars of the highest standards (bars that are rich in coconut soap and high in fat), these surfactant formulations in liquid form of the prior art, either have a poor foam generation, or provide very little softness to the skin. As expected, the generation of foam is a function of the selection of the surfactant and its concentration. The conceivable amount of surfactant compositions in liquid form formulated with or without skin sensing agents is numerous. The rheological and phase properties are exhibited by very extensive prototypes (for example, thin liquids, gels, coarse pastes, solutions, emulsions). The phase stability of the prototypes is very acceptable in short periods of time, but over a prolonged period of time, only a small fraction of them retain their original properties and acceptability. See, for example, US Patents Nos .: 4,338.21 1, issued to Stíros, issued on July 6, 1982; 4,310,433, granted to Stiros, issued on January 12, 1982; and 4,842,850, granted to Vu, issued June 27, 1989, which have been incorporated into the present description as a reference. As a simple variable, the optimization of foam generation is a completely simple process. The use of highly foamed anionic surfactants that are known, with foam propellants produce an acceptable volume of foam. Unfortunately, the most foaming anionic surfactants are also generally those that produce the most irritation in the skin, and are the worst in terms of clinical smoothness. Surfactants that are among the most mild with minimal skin irritation, such as sulfate (NH4AE12S) of ammonium lauryl ether (12 EO), are extremely deficient in foam generation. These two facts separately, make the selection of the surfactant and optimization process in foam propulsion, is an act of delicate balance. See, for example, U.S. Patent No. 4,338.21 1, supra, which is incorporated herein by reference. The introduction of an antibacterial in the balance of the composition, results in additional softness problems, foam generation, and efficiency. As reported in the commercial literature, certain ethoxylated non-ionic mild surfactants, for example, Tween® 80 (ICI Americas, Inc.), and lecithin have deactivating effects in the desgermenisation of a preferred antibacterial, Triclosan (Irgansan® DP 300, which we also refer to in this document as "TCS"), according to the Irgasan Trade Bulletin DP 300 of 1988 of Ciba-Geigy. In fact, there are some strict requirements for skin cleansers, which limit the choice of active surface and antibacterial agents, and as a result, the final desgermenisation formulations represent a degree of compromise. The softness is often obtained at the expense of effective desgermenisation or effective cleaning, and the generation of foam can be sacrificed, either by the softness, the stability of the product, or both.

The present invention offers a valuable combination of desirable properties for skin cleansing formulations in liquid form. Accordingly, it is an object of the present invention to develop skin cleansing compositions in liquid form, which exhibit improved softness, good cleansing and foaming, and good desgering properties. Other objects of the present invention will be appreciated from the following detailed description of the invention.

Soft compositions for personal cleansing in liquid form The gentle cleanser for personal cleansing in liquid form of the present invention is substantially free of alkyl sulfate surfactants, since alkyl sulfates are relatively harsh to the skin. It is recognized that some alkyl sulfate will generally be present in said composition, as a result of which it has been present in the raw materials of ethoxylated alkyl sulfate, which are available in the market. For example, the ethoxylated alkyl sulfate (3) available on the market generally contains about 20 parts by weight of alkyl sulfate; the commercially available alkyl ethoxylated sulfate (2) contains from about 25 parts to about 40 parts of alkyl sulfate. For the purposes of the present invention, "substantially free of alkyl sulfate", means that the compositions of the present invention, must have a weight ratio of alkyl sulfate: ethoxylated alkyl sulfate (with an average degree of ethoxylation of 2.5 and as indicated above), not greater than about 0.35, preferably not greater than about 0.30, more preferably not greater than about 0.25. For the ethoxylated alkyl sulfate, with an average level of ethoxylation lower than 2.5, the ratio should not be greater than about 0.40, preferably not greater than 0.35, more preferably not greater than 0.30, still more preferred not greater than 0.25. It is preferable that an additional amount of alkyl sulfate, which is different from that which is inherently in the ethoxylated alkyl sulfate, is not added. In order to reduce the weight ratio of alkyl sulfate: ethoxylated alkyl sulfate, narrow ranges of ethoxylation can be used. "The narrow ranges of ethoxylation" refer to the ethoxylated alkyl sulfate surfactants that have been processed, to reduce the alkyl sulfates and, optionally, the ethoxylated alkyl sulfates which are outside the desired ethoxylation range. The narrow ranges of ethoxylation can be used, reducing the weight ratio of the alkyl sulfate: ethoxylated alkyl sulfate, including such low proportions, as about 0.2, or even about 0.1, and lower. It is also preferred that other ingredients that are unduly harsh to the skin are not added to the mild personal cleansing compositions in liquid form of the present invention.

Still other ammonium surfactants include the class designated as succinamates. This class includes active surface agents, such as disodium N-octadecylsulfosuccinamate; N- (1,2-dicarboxyethyl) -N-octadecylsulfosuccinamate tetrasodium; diamyl ester of sodium sulfosuccinic acid. Other suitable anionic surfactants usable in the present invention are olefin sulfonates having from about 12 to about 24 carbon atoms. The term "olefin sulfonates", as used in the present application, means compounds of α-olefins which can be produced by sulfonation with simple sulfur trioxide, followed by neutralization of the acid reaction mixture, under such conditions any of the sulfones that have been formed in the reaction, are hydrolyzed to produce the corresponding hydroxy-alkane sulfonates. Sulfur trioxide may be in liquid or gaseous form, and is usually, but not necessarily, diluted by inert diluents, for example, by liquid SO2, chlorinated hydrocarbons, etc. , when they are used in the liquid form; or by air, nitrogen, gaseous SO2, etc. , when they are used in the gaseous form. Another class of anionic surfactants are the b-alkyloxy alkane sulfonates. These compounds have the following formula: OR2 H I I Rj - C - C - SO3M H H where R- | , is a straight chain alkyl group, having from about 6 to about 20 carbon atoms, R 2 is a lower alkyl group having from about 1 (preferably) to about 3 carbon atoms, and M is a water soluble cation . Many additional synthetic anionic surfactants are described in McCutcheon's 1989 Emulsifier and Detergents publication. published by M C. Publishing Co !, which is incorporated herein by reference. Also US Patent No. 3,929,678, issued to Laughlin and Associates, issued December 30, 1975, which is incorporated herein by reference, discloses many other anionic surfactants, as well as other types of surfactants. The soaps, of course, are also within the scope of the anionic detergent surfactants, which can be used. , Non-ionic Surfactants A wide variety of non-ionic surfactants can be used. Nonionic surfactants include those broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature), with an organic hydrophobic compound, which may be aliphatic or alkyl of aromatic nature. Examples of the types of nonionic surfactants are: 1. The polyethylene oxide condensates of alkyl phenols, for example, the condensation products of alkyl phenols, having an alkyl group containing from about 6 to about 20 carbon atoms, preferably from about 6 to about 12, in a configuration of , either straight chain or branched chain, with ethylene oxide, said ethylene oxide being present, in equal amounts to from about 10 to about 60 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in said compounds can be derived, for example, from polymerized propylene, diisobutylene, octane, or nonane. 2. Those derived from the condensation of ethylene oxide with the product resulting from the reaction of propylene oxide and the ethylene diamine products, which may be of varied composition, depending on the balance desired between the hydrophobic and hydrophilic elements. . For example, compounds containing from about 40 parts to about 80 parts of polydeoxyethylene by weight, and having a molecular weight of from about 5,000 to about 1, 000, resulting from the reaction of ethylene oxide groups are satisfactory. with a hydrophobic base, constituted of the reaction product of the ethylene diamine and the excess of propylene oxide, said base having a molecular weight in the order of cessation of about 2,500, up to about 3,000. 3. The condensation product of the aliphatic alcohols, having from about 8 to about 18 carbon atoms, in a configuration of either straight chain or branched chain, with ethylene oxide, for example a condensate of ethylene oxide of coconut alcohol, has from about 10 to about 30 moles of ethylene oxide per mole of coconut alcohol, the coconut alcohol fraction has from about 10 to about 14 carbon atoms. 4.
