In December 2021, the company Shebekinskaya industrialnaya khimiya, LLC (Russia) conducted technological trials of the recipe of dyeing fur skins in light shades through optical bleaching. The product “Vega OO” was used as an optical dye (bleaching agent) for fur, wool, silk and polyamide fibers. "Vega OO" is fixed on the hair, converting the light of the ultraviolet region of the spectrum into a white (bluish) glow, which enhances whiteness and masks yellow shades. The trials were carried out with a positive result: the shade of the dyed fur skins turned out to be light, pearl-gray. Partners have shown interest in using this recipe in the production of the article "decorative carpets". The partners were also presented with a range of acid coloured dyes of Shebekinskaya industrialnaya khimiya, LLC.
