Description

IMPROVED THICKENING AGENTS C_ _ The present invention is concerned with
thickening agents comprising dispersion(s) of at least one solid salt of acrylic acid polymer(s) and/or copolymer(s) with at least one alkali metal and/or alkanolamine in a dispersing phase consisting essentially of one or more aliphatic fatty acids, processes for their preparation and their use as thickening agents in the chemical, pharmaceutical, cosmetic, paper, textile industries.
can optionally ethylenically The use of acrylic acid polymers and copolymers cross-linked with polyfunctional unsaturated monomers as thickening agents for mainly aqueous matrices is already known.
Italian Patent 1,201,130 (1989), in the Applicant's name, discloses stable dispersions used as thickening agents for printing pastes, which are obtained by incorporating polymers of acrylic acid, which be copolymerized with other unsaturated monomer, into C 7-C22 aliphatic saturated, unsaturated or poly-unsaturated f the acrylic acid fatty acids. The dispersing phase for polymers can consist of one or more of the above mentioned fatty acids.
Though the use of the dispersions described in the above mentioned patent involves no specific difficulties, it suffers from the drawback that said dispersions are in the acidic form and, when admixed with water, they require neutralization with alkali substances (sodium hydroxide or ammonia) for compatibility with the aqueous phase as well as the 2 attainment of the desired viscosity, optionally by addition of suitable additives.
The neutralization process must be carried out after a reasonably long stirring time to provide the complete dispersion of the preparation before the addition of the neutralizing agent, in order to avoid formation of almost insoluble gel particles, as a consequence of surface solvation of the particles themselves.
Italian Patent application 19565 A/90, in the Applicant's name, discloses solid salts of acrylic acid polymers or copolymers with alkali metals or aliphatic amines. Said salts can advantageously be added directly to the desired formulations with no need for pre is dispersion processes neither for more complex processes involving neutralization.
Now it has been found that stable dispersions, useful as thickening agents, can be obtained by means of a simpler process, using salt of acrylic acid polymer or copolymer with alkali metal or alkanolamine as the dispersed phase and fatty acid as the dispersing phase. In this way, the subsequent neutralization process is nolcrg-_r necessary.
According to the invention, one or more aliphatic fatty acid of form ula R-COOH, wherein R is a C 7-C22 straight or branched aliphatic chain, which can be saturated or unsaturated with one or more double bonds, can be used.
Examples of suitable fatty acids include: dodecenic, myristoleic, palmitoleic, oleic, linoleic, linolenic, ricinoleic, lauric, myristic, palmitic, stearic, caprilic, caprinic acids and the mixtures thereof, such 1 3 as, for example, coconut, olive, peanut, castor-oil plant, sesame, scy, linseed, sunflower, spermaceti, fish, colza and pal"Im fatty acids.
Acrylic acid polymer or copolymer are preferably in the form of sodium, potassium, ammonium, mono-, dior tri-ethanolamine salts. Sodium and potassium salts are particularly preferred. Examples of acrylic acid copolymers are those with acrylic acid esters, methacrylic acid and esters thereof, acrylamide and N- substituted acryla-mides, acrylonitrile, crotonic acid, itaconic acid, maleic acid, fumaric acid, C 1-C 10 straight or branched-chain acid vinyl esters, all optionally being cross-linked with either polyfunctional monomer(s), such as methylene-bis- is acrylamide, triallyl cyanurate, divinylbenzene, or with allyl ether(s) of polyfunctional alcohol (s) such as oP glycerol, trimethylolpropane, pentaerythritol and sugars.
The dispersions of the invention are most preferably prepared by incorporating the finepowdered solid salt into the fatty acid dispersing phase under strong stirring and at room 0-ad temperature or at a temperature in which 0 said fattyphase is liquid, although preferably not above 60 C.
Alternatively, the dispersions of the invention can be prepared byfirst salifying the acrylic acid polymer or copolymer with a suitable base, such asof sodium or potassium hydroxide or alkoxide, in a non aqueous solvent, such as a lower alcohol, particularly methanol or ethanol, then mixing the resulting salt suspension with the dispersing phase, and subsequently distilling off the solvent.
4 The compositions obtained are most preferably in form of fluid pastes which are stable with time and can be dispersed in aqueous matrices, at the melting temperature of the used fatty acid (s), in order to thicken them, with no need for neutralization of the acrylic polymer and/or of the residual acidity due to the fatty acid. In case the fatty acid is solid at room temperature, before incorporating the mixtures in water, it is convenient to melt them in order to make the dispersion thereof easier. The formulations of the invention can find practical application to thicken printing pastes, polishes, cosmetic preparations, pharmaceuticals, detergents, paints, inks and the like. Accordingly such compositions which include the present dispersions are included within the scope of the present invention.
The following non-limiting Examples further illustrate embodiments of the invention. In the Examples, all parts and percentages are by weight if not otherwise stated.
EXAMPLE 1
Parts of the sodium salt of a polyacrylic acid cross-linked with 0.7% of pentaerythritol polyallyl ether, having average molecular weight of about 3,000,000, were placed into 60 parts of technical olein having the following characteristics: iodine no 85; acidity no 20.1; solidification point 30C. The mixture was homogenized with a Silverson homogenizer for 15 min., to obtain a fluid suspension capable of transfer by pump, said suspension having a viscosity of 2,800 cps, measured with a Brookfield apparatus at 200C, 20 rpm (revolutions per minute) and rotor n 11 4.
EXAMPLE 2
Parts of the polyacrylic acid sodium salt described in Example 1 are added to 70 parts of coconut fatty acids, kept melted at 5011C, and the mixture was stirred for 30 min. at 200 rpm. The fluid mass was subsequently passed through a 3 cylinder refiner, at a temperature of 40C. T h e obtained product had a viscosity of 900 cps, measured with a Brookfield apparatus at 400C, 20 rpm and rotor n 3, and it solidified at 280C.
EXAMPLE 3
Parts of the potassium salt of a 95:5 acrylic acid/acrylamide copolymer, cross-linked with 200 ppm of methylene-bis-acryla,mide, were dispersed under strong stirring in 80 parts of palm fatty acids, at 40C. The obtained mixture was refined at 4011C in a microsphere mill, to give a homogeneous fluid paste which was solid at room temperature (200C).
EXAMPLE 4
Preparation of printing pastes g of the formulation described in Example lwere added, under strong stirring, to 700 ml of water containing:
8 g of melamine fixer g of acrylic binder g of Alizarin Blue BGT pigment.
Waterwas added to 1,000 g.
The obtained pigmented paste had a viscosity of 18,000 cps, and addition of alkali to the mixture, in order to adjust PH toasuitab] level was not found recessarY.
EXAMPLE 5
Preparation of a polish for hard surfaces 250 g of an aqueous suspension containing 15 g of finely ground calcium carbonate and 2 g of ethoxylated 6 lauric alcohol, at 40C, were added with 3 g of the formulation of Example 2, and the mixture was stirred for 10 min. A homogeneous formulation WOL5 obtained, having a viscosity of 3, 000 cps, which was found suitable for use without any neutralization.
