Description

COMPOSITIONS FOR PERSONAL CLEANING FIELD OF THE INVENTION The present invention relates to foaming compositions for personal cleansing that provide superior cleansing with low irritation and good rinsing of skin, hair and the like.

BACKGROUND OF THE INVENTION Personal cleansing compositions are an important part of the daily hygiene regime of a large group of men and women around the world. However, it is known that certain cleaning substances, in particular certain facial cleansers, can also damage, in the form of skin irritation, or damage the surfaces subjected to cleaning, even if they are good for removing sebum or dirt from the skin. skin and hair The formulators' challenge is to reduce the irritation and damage caused by rubbing the product, without compromising the effectiveness of the formulation for cleaning. In order to maintain a sufficient cleansing and / or exfoliating action, such formulations frequently include particulates such as beads and encapsulated materials, in replacement of strong surfactants. Moreover, in addition to cleaning, formulators face the challenge of conditioning hair and skin while minimizing damage and irritation. In order to achieve this, formulators suspend particles or droplets of materials, such as oils or petroleum, to provide conditioning benefits. However, particulates and oil droplets must be suspended in these compositions in order to minimize migration (up or down) within the package in which they are marketed. While this is most easily achieved in a thick, non-foaming composition, consumers often desire foaming products due to their spreadability and rinsing characteristics even if they have a mild surfactant base. Suspending particulates such as beads, capsules or droplets of materials in this class of formulations is often achieved by the use of suspended polymers. Polymers in suspension known in the industry for this purpose include acidic crosslinked acrylate copolymers. Such materials are manufactured and marketed by a number of suppliers, including Noveon ™, Inc. The Noveon sales literature discloses that adding small amounts of a polyol, such as glycerin or polyethylene glycol, can help reduce the associated "granularity". with the gel compositions by the agglomeration of the polymer and / or the steps subsequent to the neutralization of the composition leading to the formation of salts; see "Polymer For Personal Care, Carbopol EDT® Resins: Formulation Tips" (Personal Care Polymer, Carbopol EDT® Resins: Advice for Formulation), March 1994.

Despite the benefits indicated by Noveon ™, the use of such suspending agents in cleaning compositions can also affect the user's perception with respect to rinsing the skin and hair cleaning composition. Through exhaustive studies of the consumption, it was detected that, when these suspension polymers are used in cleaning compositions, the consumers are left with the perception that the foam of the composition is deficient or that it is not rinsed easily. In fact, it is not unusual for consumers to be left with the impression that these compositions appear gelatinous and / or do not rinse easily after use. In addition, it has been detected that combinations of surfactants are also important for consumer satisfaction. Consumers value surfactant systems that provide a generous and abundant foam while being gentle on the skin. The high levels of amphoteric and / or zwitterionic surfactants in relation to the anionic surfactants are crucial to achieve smoothness. However, high levels of amphoteric and / or zwitterionic surfactants generally lead to high levels of salts that negatively affect the suspension capacity of suspension polymer systems. In the absence of these, many of these compositions are not commercially viable. Therefore, there is a demand for consumption of cleansing or rubbing conditioning compositions that provide abundant foam and at the same time rinse easily from hair and skin.

BRIEF DESCRIPTION OF THE INVENTION The present invention consists of a foaming cleaning composition comprising an ethoxylated alkyl polymer, at least one foaming surfactant, a crosslinked acrylate copolymer, and a particulate material. These compositions provide good foam and are easily rinsed. The particulate materials improve cleaning and exfoliation, while providing conditioning benefits without causing damage or irritation. Unless indicated otherwise, all percentages set forth herein are expressed by weight of the aforementioned material found in the compositions, such as to exclude, for example, the weight associated with the carriers, impurities and by-products found in the raw material.

DETAILED DESCRIPTION OF THE INVENTION Ethoxylated alkyl polymers The compositions of the present invention comprise ethoxylated alkyl polymers selected from the group comprising dialkyl, trialkyl and combinations of dialkyl and trialkyl substituted ethoxylated alkyl polymers. Alternatively, they comprise monoalkyl, dialkyl, trialkyl, tetraalkyl and all combinations of these of substituted ethoxylated alkyl polymers. The alkyl group can be saturated or unsaturated, branched or linear, and contains an amount of carbon atoms ranging from about 12 to about 50 carbon atoms. The amount of moles of ethylene oxide is greater than about 20, alternatively, greater than about 40. These polymers are at levels ranging from about 0.2% to about 1.0%, alternatively, from about 0.1% to about 2.0%, and as an alternative, from about 0.05% to about 5.0%, of the composition. The alkyl substitution of the ethoxylated alkyl polymer includes the monoalkyl, dialkyl, trialkyl and tetraalkyl substitution of the polymer and combinations thereof. Examples of polymers that are substituted with monoalkyl include: Esteareth-100, available as Brij 700® from Uniqema Inc., pareth alcohols, available as Performathox 480® and 490® from New Phase Technologies, Inc. Diallyl substituted polymers include PEG 120 methyl glucose dioleate, available as Glutamate DOE-120® and Glucamate DOE-120®, both from Chemron Corporation. The trialkyl substituted polymers include the PEG 120 methyl glucose trioleate, available as Glucamate LT® from Chemron Corporation. Tetraalkyl-substituted polymers include the PEG 150 pentaerythritol tetrastearate, available as Crothix® from Croda Corporation. In the present invention, the usual substitution of the polymer is with dialkyl, trialkyl or tetraalkyl and combinations thereof. Even more usual are the polymer substitutions with dialkyl, trialkyl and combinations thereof, crosslinked copolymers. The composition of the present invention includes crosslinked copolymers selected from the group comprising crosslinked acid copolymers, crosslinked copolymers of maleic anhydride and combinations thereof. The crosslinked copolymers of the present invention are those which are commonly used to thicken and suspend cosmetic agents in compositions such as shampoos, lotions and creams or other products having a medium containing an aqueous electrolyte. The crosslinked copolymers are present in the composition in the present invention at levels of from about 1% to about 2%, alternatively, from about 0.5% to about 3%, and alternatively from about 0.1% to about 5%, by weight of the composition . The cross-linked acidic copolymers of the present invention include alkyl-substituted acid copolymers. One class of alkyl substituted copolymers include a rheology modifying copolymer containing a substituted copolymer selected from the group comprising unsaturated carboxylic acid, a hydrophobic monomer, a hydrophobic chain transfer agent, a crosslinking agent, a spherical stabilizer and combinations of these. Carbopol EDT 2020 ™ by Noveon ™ is an example of this suspension agent. Detailed information on such suspending agents is described in U.S. Pat. no. 6,433,061, granted to Marchant et al., On August 13, 2002.

Another class of copolymers includes a practically crosslinked alkali-swellable acrylate copolymer which is described in U.S. Pat. no. 6,635,702. Carbopol Aqua SF-1 ™ by Noveon ™ is an example of this type of suspending agent. Another class of commercially available copolymers, which are useful herein, include copolymers of C10.30 alkyl acrylates with one or more acrylic acid monomers, methacrylic acid or one of their short chain esters (i.e., an alcohol of C1). -4), wherein the crosslinking agent is an allyl ether of sucrose or pentaerythritol. These copolymers are known as C10.30 alkyl acrylate crosslinked polymers / acrylates and are commercially available as Carbopol® 1342, Pemulen® TR-1 and Pemulen® TR-2, from Noveon ™. Still another class of copolymers includes the polymers classified in the alkyl vinyl acrylate / crosslinked polymers category, commercially available as Stabylen® 30, from 3V, Inc. Cross-linked maleic anhydride copolymers include crosslinked copolymers of alkyl vinyl ether of 0, -0.0 / maleic anhydride. Stabileze Q ™, from ISP Corporation, is an example of this type of material. In order to be effective, the maleic anhydride segment of this copolymer must be at least partially neutralized, such that the copolymer becomes anionic. Particularly useful are the crosslinked copolymers including the alkyl-substituted cross-linked acid copolymers and the alkali-swellable acrylate copolymers.

As described in Technical Data Sheet no. 244 from Noveon, the suspension capacity of the formula can be approximated by performance value measurements. One method is the Brookfield performance value extrapolation method. The performance value of Brookfield (in the present called BYV, for its acronym in English) is calculated by the following formula: BYV. { dynlcml 2) _ (7I - 72) 100 where? 1 and? 2 are the apparent viscosities of the sample, measured at shaft speeds of 0.05 rad / s (0.5 rpm) and 0.1 rad / s (1.0 rpm), respectively. To determine the BYV of compositions, whose viscosity is from about 5 Pa.s (5000 cP) to about 25 Pa.s (25,000 cP), a 2 rad / s (20 RPM), a Brookfield viscometer with axes RV2 and RV3 must be used. As is known to those experienced in the industry, to suspend materials in the compositions successfully, the BYV of such compositions varies depending on the ratio of the particle size of the suspended material and the difference of the density of the dispersed phase and the continuous phase, as established in the Stokes law. In the present invention, the BYV is greater than about 150 dyn / cm2 as an alternative, greater than about 100 dyn / cm2 as an alternative, greater than about 75 dyn / cm2 and as an alternative, greater than about 50 dyn / cm2.

Foam volume test The average foam volume is a measurement that is determined by the foam volume test. This test provides a consistent measure of the foam / foam former volume generated by the articles described herein. The foam volume test protocol is described as follows: (1) Wash your hands carefully before performing the test, using the product to be tested. This will remove any dirt that may affect the accuracy of the measurement; (2) dry your hands with a towel; (3) Dispense, with a syringe, 1 cc of the composition in the palm of your hand; (4) add 2 cc of water (medium hardness of approximately 8-10 grains per 3.78 I (gallon)) on the hands and rub them together (very naturally) doing circular movements 5 times; (5) rotate your hands one over the other 3 times and collect the foam generated in a cylinder or beaker that is large enough to contain the generated foam; (6) level the foam with a plastic spatula and measure the volume; and (7) complete the test three times in total for each composition in order to obtain the average foam volume of the composition; said average foam volume is calculated by adding the measured foam volumes of each sample and dividing the number obtained by three. The compositions of the present invention preferably comprise a level of foaming surfactant wherein the average foam volume of the composition is greater than or equal to about 15 ml, alternatively, greater than or equal to about 20 ml, still more preferably, greater or same as approximately 30 ml.
