Abstract

The present invention relates to a mild shampoo composition that is a low-irritant to the skin, hair and eyes. The shampoo composition comprises, per 100 parts by weight, from about 5 to about 50 parts of a sensitive surfactant mixture comprising (a) from about 10 to about 60 percent by weight of the mixture of at least one strong anionic surfactant, (b) from about 10 to about 40 percent by weight of the mixture of at least one amphoteric surfactant and (c) from about 10 to about 60 percent by weight of the mixture of at least one alkyl saccharide nonionic surfactant.

Description

MILD SHAMPOO COMPOSITION

BACKGROUND OF THE INVENTION This invention relates to a shampoo composition, and in particular, to a hair or body shampoo composition with good cleansing performance that is also mild to the user's skin, hair and eyes and contains a sensitive surfactant mixture having at least one strong anionic surfactant, at least one amphoteric surfactant and at least one alkyl saccharide nonionic surfactant. Anionic surfactants are a desirable component in shampoo compositions because of their good cleaning properties. A disadvantage of anionic surfactants, however, is that they are harsh. Thus, formulating a shampoo composition that is mild often involves compromising cleansing performance.

For example, United States Patent No. 5,221,530 issued to Janchitraponvej et al. describes a mild conditioning shampoo for hair. To provide a mild conditioning shampoo, Janchitraponvej et al. restrict the amount of anionic surfactants in the composition. Alternatively, Janchitraponvej et al. uses only "weaker and milder" anionic surfactants to achieve lower irritation. These low- irritation anionic surfactants include disodium salts of an ethoxylated lauryl alcohol half ester of sulfosuccinic acid, disodisum salts of substituted ethanolamide half esters of sulfosuccinic acid, carboxylic acids and carboxylate detergents. The use of such low-irritation anionic surfactants, however, may result in a loss of cleansing performance.

It has surprisingly been found that a mild shampoo composition that produces high foam stability and good cleansing performance can be obtained by including a sensitive surfactant mixture that includes a "strong" anionic surfactant, at least one amphoteric surfactant and at least one alkyl saccharide nonionic surfactant.

SUMMARY OF THE INVENTION

The present invention relates to a mild shampoo composition comprising, per 100 parts by weight, from about 5 to about 50 parts of a sensitive surfactant mixture comprising (a) from about 10 to about 60 percent by weight of the mixture of at least one strong anionic surfactant, (b) from about 10 to about 40 percent by weight of the mixture of at least one amphoteric surfactant and (c) from about 10 to about 60 percent by weight of the mixture of at least one alkyl saccharide nonionic surfactant. Preferably, the ratio of components (a) to (b) in the sensitive surfactant mixture is between about 1: 1 and about 5: 1. The preferred ratio of components (b) to (c) is between about 1 : 1 and about 1:4.

"Strong anionic surfactants" includes synthetic anionic surfactants containing phosphate, sulfate or sulfonate functional groups. The preferred strong anionic surfactant is a synthetic anionic surfactant selected from the group consisting of long chain (C₁₀ to C₂₂) alkyl sulfates, long chain (C_l0 to C₂₂) alkyl sulfates, long chain (C_I0 to C ) partially or fully ethoxylated alkyl sulfates, long chain (C₁₀ to C₂₂) sulfonate and combinations thereof. More preferably, the anionic surfactant component of the shampoo composition is a combination of alkyl sulfates and alkyl ether sulfates.

Useful amphoteric surfactants include mono- and diacetates, betainses, imidazolines, glycinates, isothionates, mono- and diproprionates, hydroxy sultaines and taurates. The preferred amphoteric surfactants are glycinates. The alkyl saccharide nonionic surfactant is an aliphatic alkyl saccharide represented by formula (I):

R'-O-O^O G),, (I) wherein R¹ represents a linear or branched alkyl group containing from about 8 to about 22 carbon atoms, a linear or branched aikenyl group containing from about 8 to about 22 carbon atoms, or an alkylphenyl group containing from about 8 to about 22 carbon atoms, with the alkyl group being either linear or branched, R² represents an alkylene group containing from 2 to 4 carbon atoms, and G represents a reduced sugar containing from 5 to 6 carbon atoms, m denotes a value of 0 to 10 and n denotes a value from about 1 to about 10. A preferred alkyl saccharide nonionic surfactant is decyl polyglucoside, wherein R' is a saturated alkyl group containing 10 carbon atoms, G is a glucose unit, m has a value of 0 and n has a value of about 1.5.

The shampoo composition may also contain up to about 10 parts of conventional additives.

Unexpectedly, it has been found that shampoo compositions that incorporate the sensitive surfactant mixture of the present invention produces exceptional mildness as well as superior cleansing performance and high foam stability compared to commonly used mild shampoo compositions.

It is noted that, unless otherwise stated, all percentages given in this specification and the appended claims refer to percentages by weight of the total composition. These and other objects, advantages, and features of the present invention will be better understood upon review of the following detailed description of the preferred embodiments. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to a mild shampoo composition comprising, per 100 parts by weight, from about 5 to about 50 parts of a sensitive surfactant mixture comprising (a) from about 10 to about 60 percent by weight of the mixture of at least one strong anionic surfactant, (b) from about 10 to about 40 percent by weight of the mixture of at least one amphoteric surfactant and (c) from about 10 to about 60 percent by weight of the mixture of at least one alkyl saccharide nonionic surfactant. The shampoo composition can be used as a hair or body shampoo that is sensitive to the hair and skin. In a preferred embodiment, the shampoo composition does not cause irritation to mucous membranes such as the eye.

Anionic surfactants are included to provide cleansing performance and a high foam level that is desirable to consumers. Generally, anionic cleansing surfactants include a hydrophobic moiety, such as a carbon chain including from about 8 carbon atoms to about 30 carbon atoms, and particularly from about 12 carbon atoms to about 22 carbon atoms and further includes a hydrophilic moiety. The term "strong anionic surfactant" includes the anionic surfactants having a hydrophilic moiety such as sulfate, sulfonate, or phosphate. Often, the hydrophobic carbon chain is esterified, such as with ethylene oxide or propylene oxide, to impart a particular physical property, such as increased water-solubility or reduced surface tension, to the anionic cleansing agent.

Anionic surfactants particularly useful in the present invention include strong anionic surfactants containing at least one sulfur group. Thus, for example, the anionic surfactant useful in the present invention includes sulfated and sulfonated anionic surfactants. Useful sulfated anionic surfactants include but are not limited to primary and secondary alkyl sulfates, primary and secondary sulfates of ethoxylated alcohols and sulfates of fatty esters. Useful sulfonated anionic surfactants include but are not limited to sulfonates of alkylbenzene, sulfonates of dodecyl benzene, sulfonates of tridecylbenzene, primary and secondary alkyl sulfonates, alpha olefin sulfonates, sulfonates of naphthalene and alkyl naphthalene, sulfonates of petroleum and combinations thereof. Specific examples of strong anionic surfactants useful in the present invention include but are not limited to those that are listed in McCutcheon's Emulsifiers & Detergents. Annual 1992 and in Janchitraponvej et al. , the relevant portions of both are incorporated herein by reference.

Preferred strong anionic surfactants of the present invention include alkyl sulfates and ether sulfates. Alkyl sulfates include, for example, sulfates derived from natural alcohols having from 8 to 22 carbon atoms. Thus, alkyl sulfates include, for example, sodium lauryl sulfates, ammonium lauryl sulfates, sodium myristyl sulfates, and ammonium myristyl sulfates. Ether sulfates include, for example, the alkyl ether sulfates such as polyoxyethylene alkyl ether sulfates and tridecyl ether sulfates, alkyl ether sulfates derived from natural alcohol such as sodium lauryl alcohol polyglycol ether sulfates and fatty alcohol ether sulfates, alkyl ether sulfates derived from synthetic alcohol, and ether sulfates derived from aliphatic carboxylic acids such as sodium lauryl ether sulfates, sodium myristyl ether sulfates, polyoxyethylene lauryl ether sulfates, triethanolamine lauryl ether sulfates and ammonium lauryl ether sulfates. Particular examples of these strong anionic surfactants include but are not limited to those that can be found in McCutcheon's.

In a preferred embodiment of the invention, the strong anionic surfactant is selected from the group consisting of long-chain alkyl sulfates, long- chain alkyl sulfonates, long-chain partially or fully ethoxylated alkyl sulfates, long-chain sulfonate and combinations thereof. The term "long -chain" refers to alkyl chains containing from 10 to 22 carbon atoms.

A preferred embodiment includes a strong anionic surfactant that is a combination of long-chain alkyl sulfates and long-chain partially or fully ethoxylated alkyl sulfates. Preferably, the amount of long-chain ethoxylated alkyl sulfates is greater than that of the long-chain alkyl sulfates. More preferably, the amount of long-chain ethoxylated alkyl sulfates is present at a level from about 60 to about 80 percent of the total strong anionic surfactant component. Preferably, the ethoxylated alkyl sulfates are included at a level of from about 10 to about 30 percent of the sensitive surfactant mixture.

The amount of strong anionic surfactant component is included in an amount from about 1 to about 15 percent of the total shampoo composition. Preferably, the strong anionic surfactant is included in an amount of from about 3 to about 7.5 percent of the total shampoo composition. The more preferred amount of strong anionic surfactants is from about 3.5 to about 5 percent of the total shampoo composition.

Amphoteric surfactants are provided in the shampoo composition as a co-surfactant to improve cleansing performance while at the same time contribute to the mildness of the shampoo composition. Amphoteric surfactants characteristically contain both basic and acidic functional groups. In acidic environments, amphoteric surfactants become protonated, thereby acquire positive charge. In alkaline environments they lose a proton and have a net negative charge. Examples of amphoteric surfactants useful in the present invention include, but are not limited to, mono- and diacetates, betaines, imidazolines, glycinates, isothionates, mono- and diproprionates, hydroxy sultaines, taurates, and combinations thereof. Particular examples of amphoteric surfactants include but are not limited to those that can be found in McCutcheon's, the relevant portions are incoφorated herein by reference.

The preferred amphoteric surfactant are glycinates. Glycinates are acyl derivatives of ethylenediamines and salts thereof. These compounds are also classifed as imidazoline derivatives. This category of amphoteric surfactant includes monocarboxylates, dicarboxylates and sulfonates, where the structural distinction is primarily in the fatty side chain. Particular examples of glycinates include, but are not limited to, cocoamphocarboxyglycinate, cocoamphoglycinate, lauroamphocarboxyglycinate, lauroamphoglycinate and salts thereof.

The amphoteric surfactant component is included in an amount from about 1 to about 15 percent of the total shampoo composition. Preferably, the amphoteric surfactant component is included in an amount of from about 1.5 to about 5 percent of the total shampoo composition. The more preferred amount of amphoteric surfactant component is from about about 2 to about 4 percent of the total shampoo composition. The nonionic surfactants useful in the present invention include aliphatic saccharide nonionic surfactants represented by formula (I):

Like the amphoteric surfactants, the aliphatic saccharide nonionic surfactants are provided in the shampoo composition as a co-surfactant to improve the cleansing performance while at the same time contribute to the mildness of the shampoo composition. In addition, aliphatic saccharide surfactants also contribute to foam stability. The aliphatic saccharide nonionic surfactant component is included in an amount from about 1 to about 15 percent of the total shampoo composition. Preferably, the aliphatic saccharide nonionic surfactant component is included in an amount of from about 1.5 to about 10 percent of the total shampoo composition.

The sensitive surfactant mixture containing the described strong anionic. amphoteric and aliphatic saccharide nonionic surfactants is preferably included in the shampoo composition at a level of from about 5 to about 25 percent, preferably from about 8 to about 15 percent.

In a preferred embodiment of the invention, the ratio from the amount of anionic surfactant to the amount of amphoteric surfactant is between about 1 : 1 and about 6:1, preferably between about 1: 1 and about 5: 1, more preferably between about 1.5:1 and about 4: 1. The ratio between the amount of amphoteric surfactant to the amount of aliphatic saccharide nonionic surfactant is between about 1:1 and about 1:6, preferably between about 1: 1 and about 1 :4, more preferably between about 1: 1.5 and about 1:3.

The present invention may also contain other nonionic surfactants commonly used in shampoo compositions, such as, for example, alkanolamides, amine oxides, alkoxylated alcohols and phenols, block polymers, alkoxylated amines and combinations thereof, so long as they do not detract from the advantageous features of mildness and improved cleansing performance of the present invention.

The shampoo composition can contain up to about 10 percent of the optional ingredients generally described below.

The shampoo composition of the present invention may also include common optional ingredients for shampoo compositions such as humectants (such as propylene glycol, glycerin, sorbitol, and the like); viscosity adjusting agents

(such as carboxyvinyl polymer, methyl cellulose, hydroxyethyl cellulose, polyoxyethyleneglycol distearate, ethanol, and the like); opacifiers; pearlescing agents; perfumes; dyes; pigments; ultraviolet ray absorbers; antioxidants; biocidal agents (such as Trichlosan, Trichlorocarban and the like); antiphlogistic agents (such as potassium glycol phosphate, tocopherol acetate and the like); anti- dandruff agents (such as zinc pyrithione, Octopirox and the like); antiseptics (such as methyl paraben, butyl paraben and the like); preservatives and the like may be optionally formulated into the shampoo composition inasmuch as the effect of the present invention is not affected. These additives are preferably present in the composition in combined amounts of less than 5% and in individual amounts of less than 2% each.

In a preferred embodiment of the present invention, the shampoo composition is a neutral to slightly acidic composition and has a pH of between about 5 and about 7, preferably between about 5.8 and about 6.9. The shampoo composition of the present invention can be relatively viscous dispersions that are stable to phase separation at a temperature of from about 20° C. to about 25° C. for a period of time of at least 24 hours after preparation, and typically are stable to phase separation indefmitely at such temperatures. The compositions of the present invention usually are emulsions that are stable to phase separation at a temperature of about 25° C. for a period of about 24 hours after preparation. The emulsions should demonstrate sufficient stability to phase separation at temperatures normally found in commercial product storage and shipping to remain unaffected for period of one year or more. The shampoo composition preferably has a viscosity value of between about 3,000 and about 10,000 centipoise at 25° C.

The balance of the composition of the shampoo composition of the present invention comprises water. In general, any type of water can be used in the composition, although good manufacturing procedures usually dictate that the water be deionized and substantially free of major contaminants and impurities. It is understood that the amount of water can be varied depending upon the desired concentration of the final product. The shampoo composition of the present invention has been found to exhibit high levels of foam while at the same time exhibit mildness to the hair and skin. In addition, the shampoo composition has been found to be a low- irritant to the eye so as to not cause tears.

The following nonlimiting examples are given to illustrate the compositions and the advantages of the invention.

EXAMPLE 1

Table I illustrates sixy shampoo formulations. The formulations contained a citric acid premix and a sodium chloride premix, meaning that the components in the premix were combined to form an aqueous solution prior to addition to the formulation.

Each shampoo formulation was evaluated in vitro to assess and compare their irritation potentials in the following manner. An amount of each formulation was applied to a tissue substrate, which was placed in a Skin² ZK1000 model, obtained from Advanced Tissue Sciences. The Skin² ZK1000 model consists of normal dividing, metabolically active fibroblasts. These fibroblasts were exposed to each formulation for a period of from about 16 to about 24 hours. An MTT assay was conducted to measure the cytotoxicity. An MTT₅₀ value was determined for each formulation. MTT₅₀ measures the concentration of test material that causes 50% cell death in the tissue substrates when compared with untreated controls. A shampoo formulation having a MTT₅₀ value of above 800 μg/mL is considered mild enough to be classified as a "baby" shampoo. The results are shown in Table II.

The foam volume of each formulation was also measured. Foam volume reflects the cleansing performance of the formulations. A formulation is considered to have a good or acceptable foam level when its foam volume is above 120 milliliters (mL). The results are also shown in Table II.
