/VA) a ternary mixture of a copolymer, at least one hydrophilic cationic quaternary ammonium compound, and a water-soluble nonionic cellulose polymer in an aqueous medium, which can be transparent or opaque, and treated. The present invention relates to a novel hair rinse conditioning composition that can provide extremely smooth feel and excellent gloss properties to treated hair. The use of this ternary mixture is essential in order to obtain a very smooth feel and excellent gloss properties. Also, this mixture can be easily and completely removed from the hair by simple shampooing and does not result in unpleasant conditioner deposits on the hair.

Prior Art: Conventional rinse conditioners consist of cationic fatty alcohol systems that tend to coat the hair with oils and greasiness. The cationic quaternary compound has one or more hydrophobic groups such as lauryl, heptyl, stearin, or benzyl groups attached to the nitrogen atom, or U.S. Pat.

These cationic substances that are substantial in hair are the cationic substances! It is used to emulsify oily or fatty substances such as fatty alcohols, amides, or glycols to enhance the combability of IIJM on wet and dry hair. Unfortunately, those give oily or greasy conditioning that leaves hair with lackluster results.

The prior art uses PVP/VA in hair setting compositions.

The objects and advantages of the invention will be apparent to those skilled in the art upon consideration of the following description, or may be learned by practice of the invention, and the objects and advantages of the invention will be understood by the means and advantages particularly reflected in the appended claims. It can also be understood and achieved through combinations.

SUMMARY OF THE INVENTION To achieve the foregoing and other objects and by virtue of the present invention, as herein embodied and broadly described,
The novel hair rinse conditioning composition of the present invention comprises polyvinylpyrrolidone/vinyl acetate (PVP/VA) copolymer, at least one hydrophilic cationic compound free of alkyl or alkenyl groups having at least 8 carbon atoms in the molecule. A ternary mixture of a quaternary compound and a water-soluble nonionic cellulose polymer is contained in an aqueous medium. The aqueous medium is about 71 to 99.3%, preferably 80 to 98.3%, most preferably 90 to 97% by weight of the composition.
．． It constitutes 7% by weight.

More specifically, the present invention imparts an extremely smooth feel and excellent shine to treated hair, and uses about 0.5 to 1.5% by weight of PVP as an essential conditioning agent.
/VA copolymer, at least one cationic quaternary polymer having a parent group attached to a nitrogen atom of about 0.1 to 10%
and 0.1 to 4% by weight of a water-soluble nonionic cellulose polymer in 71 to 99.3% by weight of an aqueous medium.

Performance criteria for a good hair conditioning rinse are as follows. i.e. well dispersed during the application time; extremely easy to comb through wet hair, i.e. without damaging the hair and not tangle it; easy to handle and comb through dry hair; and oily hair. The goal is to maintain good hair luster without feeling tactile. Typically, unfiltered hair is shiny and hair treated with a rinse conditioner is generally dull in appearance.

It has been discovered that a more desirable rinse conditioner can be made by substituting a polyvinylpyrrolidone/vinyl acetate (PVP/VA) copolymer in place of the commonly used fatty materials. Such conditioners provide hair with a silky feel, good manageability, and excellent shine. Furthermore, a rinse conditioner that gives an extremely dry feel and excellent shine to the hair is made by combining such a polyvinylpyrrolidone/vinyl acetate copolymer with a hydrophilic quaternary ammonium arsenide,
That is, they can be made in combination with compounds that are completely or partially soluble in water and do not contain hydrophobic alkyl or alkenyl groups of more than 8 carbon atoms in the molecule. This improved rinse conditioner provides treated hair with the ease of combing wet hair, the sheen of loose hair, the manageability of hair, and the extremely good manageability of dry hair. The addition of more hydrophilic cationic compounds improves the performance of PVP/VA copolymer rinse conditioners even when common hydrophobic cationic compounds such as stearyldimethylbenzylammonium chloride or trihydrogenated tallow dimethylammonium chloride are present. It has also been found to increase the shine of hair. Furthermore, the presence of water-soluble nonionic cellulose polymers further enhances the conditioning properties of the hair rinse conditioner. The interaction of this ternary component mixture is responsible for the superior and unexpected conditioning effects, including essentially no deposition of conditioner onto the hair. The three essential components are completely compatible.

Essential 5 of the present invention. One of the ff components, P, VP/VA copolymer, is a substantially water-insoluble film-forming material used in the prior art in hair sprays, liquid or foam hair setting compositions, and the like. A suitable PVP/VA copolymer has a PVP/VA weight ratio of 70:30 to 30.
:70 and is available from GAF as a clear liquid ethanol or isopropanol solution at 50% (A, 1.) (active ingredient) at room temperature. for example,
PVP/VA E-735 is a 50% (A, 1.) ethanol solution with a weight ratio of PVP/VA of 70:30. PVP/VAE-735P is a 50% (A,!,) ethanol solution with a PVP/VA weight ratio of 30:70, and PVP/VAI-735 is a 50% PVP/VA weight ratio of 70:30. (A, I,) Isopropanol solution. Alcoholic solutions of PVP/VA copolymers exhibit water tolerance and can therefore be used in aqueous systems such as aqueous conditioning compositions. For example, the water tolerance of E-series PVP/VA copolymers is 25 parts of 100 parts until a slight haze appears.
% copolymer, expressed in parts of water added to the anhydrous ethanol solution, is as follows.

E-535175 parts of water PVP/VA E-33
When using 5120 parts of water, a transparent film of the PVP/VA copolymer adheres to the hair treated with a composition containing the polymer, giving the hair an excellent shine. The PVP/VA copolymer is about 0.5 to 15% by weight of the composition, preferably 0.9%.
from 1.35 to 10% by weight, and most preferably from 1.35 to 3
Used in amounts of % by weight.

Another essential ingredient of the novel hair rinse composition is a cationic quaternary ammonium compound, which exhibits at least partial water solubility, and which is compatible with traditional conditioning quaternary ammonium compounds such as cetyl or stearyldimethylbenzylammonium chloride. Unlike ammonium compounds, it does not contain a hydrophobic alkyl or alkenyl group of at least 8 carbon atoms in its molecular structure, but contains a polyoxyalkylene group of at least 8 carbon atoms in its molecular structure.

This difference allows the compound to have a relatively small number of Cs-
From complete water solubility in the case of compounds containing C4 alkylene oxide groups, for example 8 propylene oxide groups, to partial water solubility in the case of compounds containing a large number of said alkylene oxide groups, for example 25 or 41 propylene oxide groups. Shows variable water solubility.

These components exhibit cationic surface functionality in oil and water, and their lipophilic orientation is proportional to the amount of polyether structure comprising the molecular weight of the individual compounds. The high degree of antistatic efficiency is due to the combined effects of the cationic activity of the compound and the hygroscopic properties of the polyether structure.

A suitable compound terminus generally corresponds to 411 in the following formula.

That is, here R and R1 are each an alkyl group having 1 to 3, preferably 1 to 2 carbon atoms; R is (CH
,,CH(R4)O). H or Al4 Ren O (CHC

Methods for producing these quaternary ammonium compounds are described in U.S. Pat. Nos. 3.1711.905 and 3.155,59.
No. 7, and No. 3.123. (It is stated in issue i41,
The disclosures of these patents are hereby incorporated by reference.

Due to the inherent nature of the quaternary ammonium compounds in the hair, they interact with the PVP/VA coatings that make up the ingredients and are treated with a sticky, glossy coating that is easily removed by washing with shampoo. It seems to cause frizzy hair. Furthermore, these ingredients are essentially non-irritating and compatible with anionic and nonionic surfactants as well as with phenolic fungicides. The cationic polyoxyalkylene quaternary ammonium compound is about 0.1% to 10%, preferably 0.45% to 8%, most preferably 1% by weight of the hair conditioning composition.
, 35 to 3% by weight. Furthermore, the weight ratio of these cationic polyoxyalkylene quaternary ammonium compounds and the PVP/VA polymer component is 1:5 to 20.
:1, preferably in the range of 1:3 to 2:1.

The third essential ingredient of hair conditioning compositions is a water-soluble nonionic cellulose polymer that acts both as a thickening agent and as a conditioning agent. Suitable cellulose polymers are selected from the group consisting of hydroxyethylcellulose and hydroxypropylmethylcellulose, with hydroxyethylcellulose being preferred. Hydroxyethyl cellulose is a reaction product of alkali cellulose and ethylene oxide, and the product is available in a number of viscosity grades. The viscosity mainly depends on the viscosity of the cellulose used in the reaction. The degree of substitution of hydroxyethyl groups per glucose unit is from 1,4 to 1,5, and these hydroxyethylcelluloses have a degree of substitution of from about 80,000 to about 900.0
It has an average molecular weight range over 0.000. No particular preference Droxyethyl cellulose is available from Percules (H
ercules, Inc.) to Natrosol (
Natrosol) 250HR. The water-soluble hydroxypropyl methylcellulose has a methoxy content of about 25 to about 32% by weight and a hydroxypropyl content of about 2 to 10%, preferably 2 to 7% by weight. Furthermore, the chain length of cellulose used in the reaction is 1° to 5000 cps, preferably 5
The molecular weight can be adjusted to give a viscosity of a 2% aqueous solution in the range of 0 to 4000 CpS.

These cellulose polymers provide stability to the composition over time by controlling viscosity. The composition maintains its viscosity without decreasing or increasing its viscosity. In addition to adjusting the viscosity of aqueous hair rinses, cellulose polymers contribute to conditioning properties. Hydrogen bonding appears to occur between the water-soluble nonionic cellulose polymer and the cationic quaternary compound, providing additional conditioning benefits to the hair rinse. This unique dual function and interaction with two other essential conditioning ingredients provides a unique hair rinse product.

The cellulose polymer content constitutes about 0.1 to 4%, preferably 0.2 to 2%, most preferably 0.25 to 1.2% by weight of the conditioning hair rinse composition.

The last essential ingredient of conditioning hair rinse compositions is an aqueous medium, primarily water.

Since PVP/VA polymers are usually obtained as ethanol or isopropanol solutions, the aqueous medium generally contains small amounts of C2-C3 alkanols. Additionally, if desired, additional amounts of C2-C5 alkanols can be added to the composition, especially if the composition is sold in the form of a "mousse."

The ratio of the aqueous medium is 71 to 99.3 in the hair rinse composition.
It is preferably in the range of 80 to 98.3% by weight, most preferably 90 to 97.7% by weight. usually,
C2-C3 alkanol is 2 to 2 of the hair rinse composition.
A small proportion of the aqueous medium, up to 5% by weight, and a relatively large amount of such alkanol will be present in the "mousse" composition.

An optionally desirable ingredient in the present hair conditioning composition is a foaming cationic surfactant that acts as a dispersant and contributes to the conditioning properties of the final product. The Kanaone surfactant contains polyethoxy groups, gluconamide propyl groups, or hydroxylated gluconamide C1-03 bonded to the nitrogen atom at a concentration of 0.1 to 8% by weight, preferably 0.5 to 4% by weight. It is a hydroxylated quaternary ammonium compound containing an alkyl group.

A typical hydroxylated cationic quaternary ammonium compound containing a gluconamidopropyl group is Quaternium 22 (γ-gluconamidopropyl dimethyl 2hydroxyethylammonium chloride). Quaternium 22 is a water-soluble gluconamide propyl quaternary salt with a concentration of 58 to 6 in water.

The hair conditioning composition according to the invention can be in the form of a clear or opaque flowable liquid, a gel or a liquid under pressure for use as a post-shampoo hair rinse or as a hair conditioning-styling mousse. The viscosity of the finished string product can range from at least 50 centimeters to up to 20,000 centimeters, and the earthen paste can be a liquid, a viscous lotion, or a cream. Gel-like hair conditioning products can be filled and extruded into any suitable container by squib tubes or by applying pressure. The product can thus be in liquid form under pressure, filled into a container which is particularly useful in the case of hair styling mousses, ie an aerosol container containing a propellant. Conditioning products can also be filled into squeeze spray containers instead of aerosol containers.

The pH of the hair conditioner of the present invention is acidic and ranges from about 3 to 6, preferably from about 4 to 5.

The hair conditioning composition e+ of the present invention includes colorants, fragrances, preservatives such as formaldehyde (formalin),
Common additional ingredients such as brighteners such as uvinul, cationic hydrophobic quaternary ammonium compounds, and other polymers such as copolymers of polydimethylsiloxane and polyoxyalkylene ethers are used. It can also be included. The total weight of these optional additions is commuting to school,
= i (does not exceed 5% by weight of the meat, and preferably does not exceed 2% by weight of the meat).

The hair conditioning composition of the present invention can be easily made by mixing the various ingredients in a predetermined manner. For example, a suitable method of preparing a composition of the invention is:
A thick homogeneous dispersion of hydroxyethylcellulose is made by mixing the hydroxyethylcellulose in cold water, heating the dispersion to about 60°C until thick and then cooling to 49°C; 4th in liquid
mix the class ammonium compound(s) (Quartanium 21, Quaternium 22, and Quaternium 36) and the PVP/VA copolymer; cool the mixture to 38°C; add the colorant, while stirring; fragrance,
It consists of adding formalin and other optional ingredients; and cooling the resulting mixture to room temperature (24°C), thereby forming an opaque or transparent product. Instead of adding the cationic quaternary compound(s) and PVP/VA copolymer later, the compounds can be premixed and added as a premix to the concentrated aqueous hydroxyethylcellulose dispersion.

These hair conditioner products are derived from the interaction of a specific ternary blend of PVP/VA copolymer, a cationic quaternary compound with a polyoxyalkylene group attached to a nitrogen atom, and a nonionic water-soluble cellulose polymer. It has unexpected excellent properties. The novel hair conditioner composition provides treated hair with a smooth feel, good manageability, and excellent shine properties, eliminating the lack of shine in clean hair that results from the use of conventional hair conditioners. Additionally, the conditioner of the present invention is completely washed off with shampoo, whereas conventional conditioning rinses or hair mousses remain, resulting in undesirable conditioner build-up on the hair.

Therefore, continuous use of conventional hair conditioners makes the hair dull. The products of the invention have overcome this problem. Other benefits of conditioning to hair include better combability of wet and dry hair, ease of handling, and good anti-static properties.

The characteristics listed in the table were evaluated.

Mousse products of Examples 8 and 9 have weak to moderate retention compared to commercially available comparable products. However, compositions 8 and 9
provides ease of application, ease of combing, and superior overall appearance compared to the control mousse. A rather poor gloss was observed in the case of Example 9, probably caused by the presence of betaine used to improve lathering. The product of Example 10 had the best overall conditioning properties, including the best sudsing and removal properties.

In Examples 8 to 10, a C3-C4 hydrocarbon propellant is present as an essential ingredient in a proportion of 3 to 20%, preferably 5 to 15% by weight of the evening mousse composition. For mousse products, the typical formulation is 3 to 20 parts of propellant and 80 to 97 parts of propellant in an aerosol container.
Since one part of the conditioning composition is mixed, the inclusion of a propellant typically proportionally reduces the proportions of the other essential ingredients.

It is understood that the foregoing detailed description is given by way of example only and that changes may be made without departing from the spirit of the invention. The separate "Summary J" is merely for the convenience of technical researchers and is not intended to have any influence on the scope of the present invention.
