The organometallic compound is preferably an organotitanate compound, particularly a tetraalkyl titanate or a titanate chelate. Such compounds are also useful for enhancing the substantivity of topical compositions applied to the body, which comprise one or more cosmetic and/or therapeutic benefit agents, a bonding agent having hydrolysable or exchangeable ligands, and a carrier.

Abstract: The present invention concerns a dye composition for dyeing human keratin fibres such as hair containing, in an appropriate medium for dyeing human keratin fibres, at least one compound chosen from among chromoionophores and fluorionophores, and at least one cosmetic additive other than water. The invention also concerns the use of a compound chosen from among the chromoionophores and fluorionophores as a direct dye for dyeing human keratin fibres, methods for dyeing human keratin fibres and a device or “kit” with several compartments.

Abstract: According to the invention, a metal salt and an oxygen source are applied to penetrate or impregnate a suitable substrate sequentially in effective amounts so as to react in contact with the substrate and produce a mineral compound fixed within the surface of the substrate. The inventive combination of a mutually compatible metal salt, oxygen source, and substrate brings about an in situ reaction, and modifies the substrate to bring about a lasting desired effect. The mineral compound that is produced according to the invention is linked to the substrate, is stable and long-lasting or permanent, and is immobilized or insolubilized in the substrate. The mineral compound is bound or contained within and on the surface of the substrate, so it may be said to be ingrained in the fibers or matrix of the substrate, or embedded within the substrate. The desired effect is preferably a color. A wide variety of metal salts may be used depending on the desired effect.

Abstract: Micro-particles of transition metals or their compounds can be generated as an integral part of a fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the fiber. The dyed fibers displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black. These colors resisted bleaching by either chemicals or light.

Abstract: Hair upon the scalp or eyelashes are treated with hair coloring or mascara compositions in hair or eyelash coloring methods. The hair is typically colored with a mascara brush to achieve streaking and a non-homogenous coloring of the hair upon the scalp or the eyelash. A copaiba resin and a metal containing pigment are combined to obtain the hair coloring product. The resultant product is applied to the hair upon the scalp or the eyelash to effect coloring of the hair upon the scalp or the eyelash.

Abstract: An aqueous dye composition is based upon a mixture of a water-soluble titanium salt, preferably titanium potassium oxalate and a tannin substance, preferably Myrobalan extract. This dye composition may be used to dye either natural fibers, synthetic fibers or blends thereof. The composition is particularly advantageous for either bottom dyeing denim fabric which can then be overdyed with indigo blue dye to provide blue-green hues or as a mordant for a basic dye.

Abstract: Method for imparting stain resistance to fibers, especially wool, which is adaptable to current wool processing methods. Steps comprise:A. treating fibers with a mordant;B. treatment with a combination of sulfonated or disulphonated surfactant together with a stain resist (e.g., syntan); andC. providing treatment with a fluorochemical in either step A. or B. in an amount sufficient to improve stain resistant properties. The improved method may be undertaken in the liquor remaining in a dye bath after dyeing fiber (spent bath process). Process pH is acid. Advantage: lowers the proportion of stain resist chemical to wool necessary to impart stain resistance. Tip sealing, using polymethacrylic resin and fluorochemical, may be an added step.

Abstract: A process is provided for the pattern dyeing of textile materials wherein dye migration may be inhibited by the in-situ formation of a coordination complex of metal-thickener-dye when the dye-thickener solution is applied to the textile material pretreated with an aqueous solution of a water soluble salt of the metal.

The thickener may be a naturally derived aqueous system thickener, such as guar gum, xanthan gum or other water-soluble gum thickener or may be a synthetically derived aqueous system thickener, such as polyacrylics and polyacrylamides.
