This invention relates to wax formulations comprised of specific poly(oxyalkylenated) colorants having fatty ester terminal groups. Preferably the wax formulation is a candle. Such polymeric ester capped colorants provide excellent coloring, decreased migratory properties, and improved balanced burning characteristics over traditional candle colorants and dyestuffs. This invention also concerns methods of making the aforementioned colored candle formulations as well as other colored wax articles, such as crayons.
This invention relates to colorants comprising a chromophore having two azo acetoacetanilide moieties, wherein said moieties each have at least one poly(oxyalkylene) chain, preferably at least two such chains. Such colorants exhibit extremely good base stability and lightfastness, particularly when incorporated within certain media and/or on the surface of certain substrates. These poly(oxyalkylene) chains provide solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or or diverse substrates. Compositions and articles comprising such colorants are provided as are methods for producing such inventive colorants.
Polymeric colored dispersant having the structure A-(B--X).sub.n, where A is an organic chromophore; B is a covalently bonded linking moiety; X is a branched or linear C.sub.50-C.sub.200 polymeric covalently linked hydrocarbon, and n is an integer from 1 to 4, and low viscosity colorant dispersions containing same having a relative interfacial tension drop of less than about 1.5.
A triacylglycerol-based wax, which can be used in candle making, is provided. The triacylglycerol-based material is predominantly includes a triacylglycerol stock which has a fatty acid profile has no more than about 25 wt. % fatty acids having less than 18 carbon atoms. In addition, the fatty acid profile of the triacylglycerol typically includes at least about 50 wt. % 18:1 fatty acid and no more than about 25 wt. % 18:0 fatty acid. In another embodiment, the triacylglycerol-based material is characterized in part by an Iodine Value of about 60 to 75. For applications such as candles, the wax commonly includes a hydrogenated vegetable oil and palmitic acid. Candles formed from triacylglycerol-based material and methods of producing the candles are also provided.
Candles formed from triacylglycerol-based wax are provided. The wax generally has a melting point of about 130 to 145.degree. F. (circa 54 to 63.degree. C.). The wax includes a triacylglycerol component and a polyol partial ester component. Examples of suitable polyol partial esters include fatty acid monoesters of glycerol and/or sorbitan. The triacylglycerol-based wax typically has an Iodine Value of about 20 to 40. The wax commonly includes at least about 70 wt. % of the triacylglycerol component and about 3 to 30 wt. % of the polyol partial ester component. The triacylglycerol component generally has a fatty acid composition which includes about 50 to 70 wt. % saturated fatty acids and about 30 to 45 wt. % 18:1 fatty acids. Methods of producing the candles from the vegetable oil-based wax are also provided.
Candles formed from vegetable oil-based wax are provided. The wax includes a triacylglycerol component and a fatty acid component, preferably about 50 to 65 wt. % of the triacylglycerol component and about 35 to 50 wt. % of the fattyacid component. The fatty acid component commonly includes at least about 90 wt. % palmitic acid, stearic acid or a mixture thereof. The triacylglycerol component may have a melting point of about 57.degree. C. to about 63.degree. C. and/or an Iodine Value of about 35 to about 45. Methods of producing the candles from the vegetable oil-based wax are also provided.
