LEATHER CHEMICALS

For over than 40 years developing solutions that evolve the world For the Leather and Footwear market, Oxiteno develops products and solutions for the entire solutions chain, from skin treatment to leather finishing and show production. The company is driven by innovation and sustainability and continually invests in the improvement of its processes and in the use of renewable materials and clean technologies. With industrial and commercial operations in nine countries in the Americas, Europe and Asia that provide services around the world, Oxiteno is a chemical company that manufactures surfactants and specialty chemicals for applications in Agrochemicals, Home Care and I&I, Paints & Coatings, Personal Care, Oil & Gas and Performance Products.

PRODUCTS FOR TANNERIES For tanning, Oxiteno supplies products that perform different functions such as humectants, detergents, dispersants, colorants, retanning and solvents, which contribute to obtaining leathers with high quality standards. For the first processing stages, from skin treatment with chrome or vegetable tanning, Oxiteno offers products such as:

Surfactants for wetting, emulsification

between bath and skins. To the steps of vegetable tanning and leather retanning tanned with chromium, Oxiteno offers products used for the dispersion of dyes and vegetable tannins, allowing time savings, color uniformity and equalizing physical properties in different skin parts. For finishing, Oxiteno offers solvents and penetrants that are used in the formulations of paints and lacquers in order to adjust the viscosity at application conditions and obtain a deeper and more durable finishing.

PRODUCTS FOR CHEMICAL FORMULATORS For chemical companies that operate with a focus on leather processing, Oxiteno offers a wide variety of solutions, which are grouped according to their functions: Detergent bases, nonionic and anionic biodegradable surfactants used in degreasing formulations;

Solubilizing agents, which facilitate the incorporation of surfactants in degreasing formulations;

Emulsifiers used in formulations of greasing oils, retanning resins and water-based resins for finishing formulations. Oxiteno has a line of surfactants in a wide range of HLB and different chemical families;

Neutralizing agents with diverse applications in all product lines used in leather, especially in degreasers and vegetable tannins;

Intermediate agents for hair removal operations, non-volatile amines used in hair removal formulations of "hair saving" processes, with benefits to the environment, working conditions and leather quality, with greater openness and cleaning of pores and area yield;

Solvents for finishing formulations;

Dispersants for formulations of vegetable tannins and dyes.

PRODUCTS FOR FOOTWEAR AND SHOE SOLE INDUSTRY For the shoe sole industry, Oxiteno provides products for vulcanization used for obtaining colored and translucent rubbers that allow better incorporation of silica to the mixture, also avoiding the adsorption of accelerators and facilitating the vulcanization process. Solvents used in adhesives formulations for shoe soles can also be supplied.
