Description

Polymer rheology modifier

The present invention relates to an acrylate-based binding rheology modifier (polymeric rheology modifier).

Rheology modifiers are generally used to modulate or modify the rheology properties of aqueous compositions. These properties include, without limitation, viscosity, flow rate, stability to viscosity change over time, and suspension of particles in such aqueous compositions. The type of denaturing agent used depends upon the particular aqueous composition to be modified and the particular end use of the modified aqueous composition. Examples of conventional rheology modifiers include thickeners such as cellulose derivatives, polyvinyl alcohols, sodium polyacrylates and other water soluble polymers, and copolymer emulsions in which monomers having acid groups are introduced onto the main chain. do.

Another type of rheology modifier known to enrich the aqueous composition is typically an associative modifier. Such binding modifiers are described in US Pat. Nos. 4,743,698, 4,600,761, RE33,156, 4,792,343, 4,384,096, 3,657,175, 5,102,936 and 5,294,692. As noted, these “alkali­swellable” thickeners have an effect upon base addition and thus raise the pH of the rich composition to basic, which does not enrich the aqueous composition with acidic pH. Thickeners of this type are also known to be incompatible with systems containing cationic components.

Other rheology modifiers that are “activated” by addition of an acid to an aqueous composition containing a modifier are also reported. As reported, emulsions are prepared via free­radical emulsion polymerization using a colloidal stabilizer. After mixing the composition to be enriched with the emulsion, acid is added to the mixture, thereby lowering the pH of the system to 6.5-0.5. Such thickeners are known to be effective in enriching certain acidic aqueous compositions, but are ineffective in enriching aqueous compositions having a base pH.

It is desirable to develop polymeric rheology modifiers that can be advantageously used to enrich both acidic and base compositions.

An object of the present invention, acrylic acid, C ₁ to C ₆ alkyl esters and methacrylic acid, a C ₁ C ₆ at least one of the selected 5 to 80% of acrylate monomer (a), nitrogen or sulfur atom weight in the group of the alkyl ester Vinyl-substituted heterocyclic compounds containing, (meth) acrylamide, mono or di (C ₁ C ₄ ) alkylamino (C ₁ C ₄ ) alkyl (meth) acrylate, mono or di (C ₁₎ Prepared by polymerizing 5 to 80% by weight of monomer (b) and 0.1 to 30% by weight of bonding monomer (c) selected from the group of C ₄ ) alkylamino (C ₁ C ₄ ) alkyl (meth) acrylamides It is to provide an acrylate-based polymer rheology modifier.

The present invention, polymer rheology, based on the total weight of monomers used to prepare the modifier (PRM), acrylic acid, C ₁ C ₆ alkyl esters and methacrylic acid C ₁ C ₆ 5~80 by weight, selected from the group of alkyl esters Vinyl substituted heterocyclic compound containing at least one of% acrylate monomer (a), nitrogen or sulfur atoms, (meth) acrylamide, mono or di (C ₁ C ₄ ) alkylamino (C ₁ C ₄ ) alkyl 5 to 80% by weight of monomer (b) selected from the group of (meth) acrylate, mono or di (C ₁ C ₄ ) alkylamino (C ₁ C ₄ ) alkyl (meth) acrylamide, and 0.1 to 30% by weight It relates to a polymer PRM produced by the polymerization of the binding monomer (c). PRMs can be used to enrich various compositions, including personal care compositions, adhesives, fabric coatings, dielectric perforations, and the like.

PRMs can be incorporated into personal care compositions in various forms, including, for example, powders, solutions, dispersions, and emulsions. Conventional methods of preparing various types of acrylate polymers are readily apparent to those of ordinary skill in the art of polymerizing acrylate polymers. Such methods include, for example, solution polymerisation, precipitation polymerisation and emulsion polymerisation. PRM can be used to thicken aqueous personal care products such as creams and lotions and haircare products such as conditioners, shampoos, hair fixatives, gels, mousses, sprays and dyes.

Although the use of the PRM of the present invention is particularly preferred for enriching aqueous personal care compositions, PRM can also be used to enrich personal care compositions containing less or no moisture. For example, in personal care compositions that are low in moisture or very low in moisture, PRMs are soluble or dispersible in the solvents used in conventional personal care compositions and can be incorporated into non-aqueous compositions. PRM can be dissolved or dispersed in a solvent prior to combination, when a solution or dispersion is added to other components, or PRM can be added to other combination components and solvents in solid form, thereby preparing a thick composition.

The acrylate monomer is selected from the group of esters made with acrylic acid and C ₁ C ₆ alcohols such as methyl, ethyl or propyl alcohol, and esters made with methacrylic acid and C ₁ C ₆ alcohols. Preferred acrylate monomers consist of C ₂ C ₆ alkyl esters of acrylic acid. More preferably, the acrylate monomer is ethyl acrylate. In the preparation of the compositions of the present invention, based on the total weight of the monomers used to make the polymer, about 5 to 80% by weight of the acrylate monomer, preferably about 15 to 70% by weight, more preferably about 40 to 70 Weight percent acrylate monomer is used.

In addition to acrylate esters, monomers may be selected from vinyl substituted heterocyclic compounds containing at least one of nitrogen or sulfur atoms, (meth) acrylamide, mono or di (C ₁ C ₄ ) alkylamino (C ₁ C ₄ ) alkyl ( Selected from the group meth) acrylate, mono or di (C ₁ C ₄ ) alkylamino (C ₁ C ₄ ) alkyl (meth) acrylamide and polymerized. Exemplary monomers include N, Ndimethylamino ethyl methacrylate (DMAEMA), N, Ndiethylamino ethyl acrylate, N, Ndiethylamino ethyl methacrylate, Ntbutylamino ethyl acrylate, Ntbutylamino ethyl Methacrylate, N, Ndimethylamino propyl acrylamide, N, Ndimethylamino propyl methacrylamide, N, Ndiethylamino propyl acrylamide and N, Ndiethylamino propyl methacrylamide. The monomer used to prepare the denaturant of the present invention is about 5 to 80% by weight, preferably about 10 to 70% by weight, more preferably about 20 to 60, based on the total weight of the monomer used to prepare the polymer. Use weight percent.

The binding monomer is used in combination with the acrylate monomer and monomer (b) in an amount in the range of about 0.1-30% by weight, based on the total weight of the monomer used to make the polymer. The binding monomer is preferably used at a level in the range of about 0.1 to 10% by weight. Such monomers include those disclosed in U.S. Pat. , All of which are hereby incorporated as such and include allyl ethers of the formula CH ₂ = CR′CH ₂ OA _m B _n A _p R, wherein R ′ is hydrogen or methyl, A is propyleneoxy or butyl Lenoxy, B is ethyleneoxy, n is zero or an integer, m and p are zero or an integer less than n, R is a hydrophobic group of at least eight carbon atoms. Preferred binding monomers consist of C ₁ C ₄ alkoxyterminated block copolymers of monoethylenically unsaturated isocyanates with 1,2butylene oxide and 1,2ethylene oxide, as disclosed in US Pat. No. 5,294,692 (Barron et al.). Urethane Reaction Products of Nonionic Surfactants; As disclosed in US Pat. No. 4,616,074 (Ruffner), a nonionic surfactant is selected from α, β ethylenically unsaturated carboxylic acids or anhydrides thereof, preferably C ₃ C ₄ mono or dica Ethylated unsaturated nose obtained by condensation with a carboxylic acid or its anhydride selected from the group consisting of leric acid or its anhydride, more preferably acrylic acid, methacrylic acid, crotonic acid, maleic acid, maleic anhydride, itaconic acid and itaconic anhydride Polymerizable surfactant monomers; monoethylenated fires, as disclosed in US Pat. No. 5,011,978 (Barron et al.) Surfactant monomers selected from urea reaction products of saturated monoisocyanates with non-ionic surfactants having amine functional groups; monohydric nonionic surfactants and monoethylenates, as disclosed in US Patent No. RE33,156 (Shay et al.); Nonionic urethane monomers which are urethane reaction products with one lacing ester group, such as unsaturated monoisocyanates, preferably alpha, alphadimethylmisopropenyl benzyl isocyanate. Especially preferred are ethylenically unsaturated copolymerizable surfactant monomers obtained by condensing a nonionic surfactant with itaconic acid. Methods for preparing such monomers are disclosed in detail in the various patents referenced above.

In addition to the required preferred monomers as above, monomers that provide crosslinking in the polymer can also be used in relatively small amounts, up to about 2% by weight, based on the total weight of the monomers used to make the polymer. In use, the crosslinking monomer is preferably used at a level of about 0.1 to 1% by weight. Cross-linking monomers include multivinyl substituted aromatic monomers, multivinyl substituted alicyclic monomers, difunctional esters of phthalic acid, difunctional esters of methacrylic acid, multifunctional esters of acrylic acid, and methylene Bisacrylamide and multivinyl substituted aliphatic monomers such as dienes, trienes and tetraenes. Exemplary crosslinking monomers include divinylbenzene, trivinylbenzene, 1,2,4trivinylcyclohexane, 1,5 hexadiene, 1,5,9 decatriene, 1,9 decadiene, 1,5heptadiene , Diallyl phthalate, ethylene glycol dimethacrylate, polyethylene glycol dimethacrylate, penta and tetraacrylate, triallyl pentaerythritol, octaallyl sucrose, cycloparaffin, cycloolefin and Nmethylenebisacrylamide do. Polyethylene glycol dimethacrylate is particularly preferred for enriching acid aqueous compositions because it tends to minimize turbidity.

Preferred PRMs in emulsion form are prepared by forming emulsions using single stage emulsion polymerisation techniques. Monomers, water, free radical initiators, effective amounts of surfactants to disperse the polymer in water upon polymerisation of the monomers, and C ₂ C ₁₂ straight or branched monohydric alcohols, and nonpolymeric polymers such as ethylene glycol, propylene glycol and glycerol About 0.5-20% by weight of alcohol, based on the total weight of the emulsion selected from the group of hydric alcohols, is combined in the polymerization reactor and maintained for the desired temperature and period of time effective for polymerizing the monomers, thereby providing monomers (a) and ( b), a polymer emulsion consisting of a copolymer of water, surfactant and alcohol is formed.

The contents of the polymerization vessel are preferably maintained for a temperature and for a period of time effective to cause polymerization of the monomers. Preferably the polymerisation reaction is initiated at about 30 ° C. such that the contents in the polymerization vessel reach a temperature of about 60 ° C. The reaction time is about 1-6 hours. One of ordinary skill in the art of emulsion polymerization will readily and accurately know which conditions of temperature and time are required, as both are well known.

Based on the total weight of the emulsion, preferably about 1 to 10% by weight of alcohol is used, more preferably about 1 to 5% by weight of alcohol. If no alcohol is used in the preparation of the emulsion, or if the amount of alcohol is not sufficient, the resulting emulsion is not stable and viscosity changes over time. It is desirable to minimize the level of alcohol used. The maximum amount of alcohol used can be practically limited depending on factors such as cost, flammability and volatile organic compound environmental problems. In addition to these factors, it is contemplated that an excess of 20% by weight of alcohol may be used.

If a stable emulsion is required, it is essential that no polymeric colloidal stabilizer, such as polyvinyl alcohol, be used throughout the emulsion polymerization in any amount that materially alters the properties of the emulsion, in particular the stability of the emulsion, during the preparation of the emulsion. Preferably, the polymeric colloidal stabilizer is one not used during emulsion preparation. It is surprising that the use of such polymeric colloidal stabilizers has resulted in unstable emulsions that change in viscosity or phase separation over time. Thus, the rheology modifiers that make up the emulsion and the emulsion are essentially free, more preferably free from polymeric colloidal stabilizers.

In water-based personal care compositions, water is a medium that is applied to a part of the body of any cosmetically active agent (CAA) that has some type of cosmetic effect, the effect of which is soft or cleansing or reinforcing or body strengthening. The personal care composition may also include a mixture of various types of CAA, such as colorants, flavors, and preservatives.

The polymer rheology modifier may be bound to the personal care composition upon combination of the composition, or the PRM may later be added to the already combined personal care composition. When combined during the preparation of a personal care composition, the PRM may be combined with water or other solutions, CAA and other components as needed and / or desired, such as emulsifiers, which are dissolved or dispersed. When used in the form of a stable emulsion, the emulsion can be combined with CAA and other components in combination, or the emulsion can be added first and later mixed to the combined composition.

Preferably, the production of the personal care composition of the present invention is to use as little PRM as possible, i.e., the minimum amount of the effective amount to enrich the personal care composition. The amount of PRM needed to effectively enrich the personal care composition depends on the particular polymer and the particular personal care composition. Typically, the rich personal care composition contains from about 0.1 to 10% by weight of PRM, based on its total weight. Preferably, the rich personal care composition contains about 0.5-5 dry weight percent PRM.

PRM meets the various needs of personal care products, such as compatibility with cationic components, rich efficacy, gel transparency, pH diversity (ie richness over a wide range of acid alkali pH ranges), and resistance to salts. do. Many examples illustrating the personal care compositions using the PRM of the present invention are evaluated and summarized below. This example includes both haircare and skincare applications, because PRM offers advantages in both areas.

The following examples illustrate the invention and are not intended to limit the scope of the invention disclosed in the following claims.

Two PRMs of the present invention were prepared via the emulsion polymerisation process described above. These PRMs are referred to as PRMs 1B and 1C, respectively. The monomer component of each PRM is shown in Table 1.

TABLE 1

(1) = All values are in weight percent based on the total weight of monomers used to make the PRM.

(2) = Setetsu # 20 Itaconate

(3) = Setetsu # 20 allyl ether

The concentration efficiency of each PRM was evaluated by measuring the viscosity contained in the prototype personal care combination. Viscosity was measured at 10 rpm using a Brookfield RVF heliopath viscometer. All viscosity values were reported in centipoise (cps). Initial viscosity measurements were taken after the personal care compositions were combined and allowed to equilibrate for 24 hours under ambient temperature and pressure. After measuring the initial viscosity, the 8-day and / or 7-day viscosity was measured after 8 or 7 days, respectively. In all cases, the viscosity of the combination containing PRM and the viscosity of the control without PRM were compared. The evaluated combinations were then subdivided into combinations 1-9. In addition, evaluation was carried out in a model system to measure stability against bleaching powders, for example peroxides. Peroxide stability was measured by boiling a 1% solid, 6% H ₂ O ₂ solution (adjust the pH to 3 using H ₃ PO ₄₎ for a total of 20 hours. Holding the results expressed as% H ₂ O _2.

Results and review

PRM is useful for a wide range of personal care products. The examples presented here highlight the effect of viscosity composition in various combinations, including cationic alpha hydroxy acid (AHA) creams, antiperspirant lotions, hair conditioners, specialty shampoos, hair and skin gels, and hair dyes. Doing. All of the evaluated PRMs were effective in increasing the viscosity of the personal care prototype in hair and skin care systems.

AHA Cream

The efficacy of PRM was evaluated in the AHA cream presented as Combination 1. This emulsion has a low pH and contains a cationic surfactant. PRM surprisingly exhibits both cation compatible and acid rich. The results are shown in Table 2.

TABLE 2

(1) and (2); PRM 1B was tested for one control, while PRM 1C was later tested independently of PRM 1B for a second but similar control.

As is evident, the addition of only 0.5% solid PRM is effective for increasing the viscosity of the cationic AHA cream compared to the cream without PRM.

Antiperspirant Lotion

The efficacy of each PRM was evaluated in an aqueous antiperspirant lotion presented as Combination 2. This low pH emulsion contains high levels of electrolytes as aluminum chlorohydrate. Therefore, PRM exhibits flame resistance and low pH viscosity composition. The results are shown in Table 3.

TABLE 3

(1) and (2); PRM 1B was tested for one control, while PRM 1C was later tested independently of PRM 1B for a second but similar control. Control ⁽²⁾ formed an emulsion of instability, ie there was phase separation, which prevented the viscosity of the control combination from being measured.

As can be seen clearly, only 1.0% solids of the bound PRMs are quite effective at increasing the viscosity of aqueous high salt antiperspirant lotions compared to products without PRMs.

Hair conditioner

PRM 1B was evaluated in a rinse off hair conditioner presented as combination 3. This combination contains a significant amount of both monomers and polymer conditioning agents. The unexpectedly good viscosity compositions shown in Table 4 demonstrate the surprising ability of PRM to make the viscosity of aqueous cation-rich combinations at the 2% solids level.

TABLE 4

shampoo

PRMs were combined with the conditioning shampoo prototype presented in Combination 4. As can be seen in Table 5, PRM 1B was effective in the viscosity composition of the shampoo after mixing. As such, PRM has been shown to increase the viscosity of highly concentrated surfactant systems.

TABLE 5

Further work was done to demonstrate the ability of PRMs to have the viscosity of highly concentrated surfactant systems. Three commercially available shampoos were later evaluated by adding PRM as a 20% polymer solid aqueous emulsion. Shampoos include mild baby shampoos (from Johnson and Johnson), Rave ^R moisturizing shampoos (from ChesebroughPond's USA Company), and Prell ^R shampoos (from Procter and Gamble). The components of these products as indicated on the labels are listed in combinations 5, 6 and 7. Although monopolized the exact level of use of the specific ingredients contained in each commercially available shampoo, the range of levels of such ingredients used by those of ordinary skill in the art is conventional, and the combination of combinations of personal care compositions It is known to those skilled in the art. As can be seen from the results shown in Table 6, PRM was effective in viscosity composition in all cases.

TABLE 6

Gel

In many hair and skincare gels, transparency is an important attribute. It is clear that low pH lotions or conditioning gels with moderate viscosity using existing thickener techniques typically cannot be prepared transparently, because commercially available clear thickeners are difficult to be compatible with low pH and / or cations, An emulsion is needed. As shown in Combination 9, PRM 1B and 1C were used to enrich the two clear AHA gels, one of which contained an additional conditioner (polyquaternium 4) and the other one. Do not. The viscosity results shown in Table 7 demonstrate that PRM effectively builds the viscosity of the clear gel.

TABLE 7

(1) and (2); PRM 1B and 1C were tested independently of each other for separate similar controls.

Hair dye

Hair dye systems are typically high levels of alkaline in use. PRM was found to be effective in the viscosity of the permanent hair dye of two components after the two components are mixed. This is true both when the polymer is delivered to an acidic developer or alkaline dye base. The results presented in Table 8 clearly indicate that PRM 1B is effective at increasing the viscosity of the commercial hair dye product Nice'n Easy ^R (manufactured by Clairol Inc.), and the composition is shown in combination 9.

TABLE 8

(1) and (2); PRM 1B and 1C were tested independently of each other for separate controls.

Peroxide stability

Compatibility with hydrogen peroxide can be an important attribute in certain personal care applications such as hair dyes. The standard screening test for peroxide compatibility is a 20 hour boiling test. Peroxide concentration was measured before and after the 20 hour boiling method. The retention of 92% or more of the initial peroxide concentration is generally pointed out as a product which shows satisfactory shelf stability. PRM 1B was evaluated in a test on 1% solids using 6% hydrogen peroxide adjusted to pH 3 with H ₃ PO ₄ . The results are summarized in Table 9.

TABLE 9

These results show that these PRMs exhibited excellent peroxide compatibility.

PRM seems to represent many possibilities in personal care applications. They form a viscosity in the presence of conventional personal care ingredients such as cations, acids, bases, salts and surfactants. The viscosity of various hair and skin combinations such as creams, lotions, antiperspirants, hair conditioners, specialty shampoos, mousses, hair and skin gels, and hair dyes is enhanced by the relatively low concentration of these polymers. Also, the dynamics of interest in personal care, such as pseudoplastic flow, are evident as these polymers.
