Abstract

The invention relates to a waxless composition for cleaning and polishing acrylic and glass surfaces, which consists of a water-in-oil emulsion comprising water, naphtha mineral spirits, an abrasive, an anti-static agent, a thickening agent, dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane, an aminofunctional siloxane capable of reacting with the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form a cross-linked siloxane film and at least one emulsifying agent having hydrophilic functional groups. The dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane and aminofunctional siloxane are sufficiently diluted to prevent reaction with one another in the emulsion so that when the composition is applied to an acrylic or glass surface and the water evaporates, the aminofunctional siloxane reacts with the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form the cross-linked siloxane film. Such a film imparts to the surface a uniform high gloss and water repellency, and efficiently protects the surface against wear and tear caused by dust, cigarette smoke and fingerprints.

WAXLESS COMPOSITION FOR CLEANING AND
POLISHING ACRYLIC AND GLASS SURFACES

The present invention pertains to improvements in the field of polish formulations. More particularly, the invention relates to a waxless composition for cleaning and polishing acrylic and glass surfaces.

Polishes are used to produce a glossy finish on a surface as well as to prolong the useful like of the surface. The gloss provided by the polish is the result of components in the polish which leave coating or film and that function to smooth and clean the surface.

Hitherto known cleaning formulations for acrylic and glass surfaces do not provide a glossy and protective film which protects the surface against wear and tear caused by dust, cigarette smoke and fingerprints. On the other hand, known polish formulations for acrylic and glass surfaces generally contain a wax as a polish ingredient and film-forming material. Some wax compositions are easy to apply and rub-off, but do not provide high gloss or extended water beading. Other wax compositions may be difficult to apply and rub-off, but provide durability for extended periods of time. Durability is generally measured by the user in terms of finish and water beading properties. Moreover, these wax compositions leave marks "of application" or smearing on the surface.
It is therefore an object of the present invention to overcome the above drawbacks and to provide a waxless composition for cleaning and polishing acrylic and glass surfaces, which results in a glossy and protective film.

O Z ~ 9 8 8 ~ 3 In accordance with the invention, there is thus provided a waxless composition for cleaning and polishing acrylic and glass surfaces, which consists of a water-in-oil emulsion comprising water, naphtha mineral spirits,an abrasive, an anti-static agent, a thickening agent, dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane, an aminofunctional siloxane capable of reacting with the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form a cross-linked siloxane film and at least one emul-sifying agent having hydrophilic functional groups. The dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane and aminofunctional siloxane are sufficiently diluted to prevent reaction with one another in the emulsion so that when the composition is applied to an acrylic or glass surface and the water evaporates, the aminofunctional siloxane reacts with the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane to form the cross-linked siloxane film. Such a film imparts to the surface a uniform high gloss and water repellency, and efficiently protects the surface against wear and tear caused by dust, cigarette smoke and fingerprints.

Dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane is sold under the trade-mark DOW CORNING 531 fluid by Dow Corning Corporation. DOW CORNING 531 fluid comprises 49 wt.% of dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane, 34 wt.% of Stoddard solvent, wt.% of isopropyl alcohol and 1 wt.% of 1,2,4-trimethyl-benzene. The aminofunctional siloxane, on the other hand, is available under the trade-mark DOW CORNING
536 fluid from Dow Corning Corporation. DOW CORNING 531 and 536 fluids are not soluble in water and hydrolyze rapidly when placed in intimate contact with water. In mineral spirits, DOW CORNING 531 fluid shows light O ~ ~ 9 8 8 11 3 precipitation or incomplete solubility. Applicant has found that by formulating these two fluids into a water-in-oil emulsion, one can produce a stable polish that does not lose performance benefits with age. The use of naphtha mineral spirits, on the other hand, prevents the deposition on the acrylic or glass surface of greasy residues, which has been encountered with other organic solvents.

According to a preferred embodiment, the dimethoxysilyl-dimethylamino-ethylaminopropyl siloxane is present in the composition in an amount ranging from about 2 to about 5% by weight, preferably about 3% by weight, based on the total weight of the composition.

The aminofunctional siloxane, on the other hand, is generally present in an amount ranging from about 0.5 to about 1.5% by weight, preferably about 1% by weight, based on the total weight of the composition.
The water is generally present in an amount ranging from about 45 to about 65% by weight, preferably about 57% by weight, based on the total weight of the composition.
The naphtha mineral spirits are generally present in an amount ranging from about 5 to about 15% by weight, preferably about 10% by weight, based on the total weight of the composition. Preferably, the naphtha mineral spirits comprise refined petroleum naphthas 0 2 ~98 8 ~ 3 having a flash point of 100~F with initial and final boiling points of 310~F and 400~F.

The abrasive is generally present in an amount ranging from about 10 to about 20% by weight, preferably about 15% by weight, based on the total weight of the composition. Examples of suitable abrasives include aluminum silicate, diatomaceous earth, pumice, fullerls earth, bentonite, silica, tripoli, hydrated calcium silicate, chalk, colloidal clay, magnesium oxide, red ion oxide and tin oxide. Preferably, use is made of aluminum silicate having a median particle size of about 0.7 u, which is available under the trade-mark KAOPOLITE SF from Kaopolite, Inc.
The anti-static agent is generally present in an amount ranging from about 0.2 to about 0.8% by weight, preferably about 0.5% by weight, based on the total weight of the composition. Preferably, the anti-static agent comprises a blend of polyethylene glycol 50 tallow amine and N-C12-C1g-alkyl N-dimethyl N-benzyl ammonium chloride in admixture with at least one organic solvent, such as the anti-static agent which is sold under the trade-mark STEPWAX and which comprises about 30-60 wt.%
of polyethylene glycol 50 tallow amine, about 10-30 wt.%
of N-C12-C1g-alkyl N-dimethyl N-benzyl ammonium chloride, about 10-30 wt.% of isopropyl alcohol and about 1-5 wt.%
of ethanol.

The thickening agent is generally present in an amount ranging from about 0.5 to about 2.5% by weight, preferably about 1.5% by weight, based on the total weight of the composition. Preferably, the thickening agent is an anionic acrylic emulsion which is available ~ Z ~8 ~ ~ ~

under the trade-mark ACUSOL 820 from ROHM and HASS
Canada, Inc.

According to a preferred embodiment, the emulsifying agent comprises a mixture of a silicone surfactant and a co-emulsifying agent. The silicone surfactant is generally present in an amount ranging from about 5 to about 10% by weight, preferably about 7.5% by weight, based on the total weight of the composition.
Preferably, the silicone surfactant is a cyclomethicone and dimethicone copolymer which is available under the trade-mark DOW CORNING 3225 C from Dow Corning Corporation. The co-emulsifying agent, on the other hand, is generally present in an amount ranging from about 0.5 to about 1.5% by weight, preferably about 1% by weight, based on the total weight of the composition. Preferably, the co-emulsifying agent is polyoxyethylene 20 sorbitan monolaurate which is sold under the trade-mark TWEEN 20 by I.C.I.
According to another preferred embodiment, the composition further includes an anti-freeze agent such as sodium citrate, in order to improve the freeze-thaw stability of the composition. The anti-freeze agent is generally present in an amount ranging from about 0.5 to about 2.5% by weight, preferably about 1.5% by weight, based on the total weight of the composition.

The composition according to the invention is easy to apply and rub-off. It provides a durable protective film which strongly adheres to an acrylic or glass surface and imparts thereto a uniform high gloss and water repellency. Such a film efficiently protects the surface against wear and tear caused by dust, cigarette smoke and fingerprints.
