Applications Optiblanc 2M/G LT Extra is recommended for Household and I&I powder detergents for washing cotton or mixed fibres containing cotton. It is structurally made in order to be fast in the solubilisation in the washing liquor. This allows a high efficiency even at low temperatures such as 5°C. Optiblanc 2M/G LT Extra is stable to alkali and peroxide bleach under the conditions normally encountered in household and industrial laundering. Optiblanc 2M/G LT Extra is resistant to hypochlorite bleach as soon as it is adsorbed on cotton, i.e. it can be used in case of hypochlorite rinse. Optiblanc 2M/G LT Extra can be added in the course of all normal detergent manufacturing operations such as spray blending, spray drying and dry blending. Optiblanc 2M/G LT Extra has an excellent cost effectiveness.
