Heavy Duty (Laundry) Powders
Unger Surfactants range of dry products is the perfect choice as primary or secondary surfactant in your Heavy Duty powder. Unger Surfactants dry products can easily and be incorporated into your formulation whether the product is produced by a non-tower, tower or dry blending route.
Traditionally laundry powders are produced by spray drying. Slurries of the key raw materials that may contain more than 50% of water yields a base powder with a low bulk density and low surfactant content. Minor components or heat sensitive ingredients, such as enzymes and bleach activators, is then introduced to the formulation by post dosing in a final step. To increase the surfactant level in such formulations one can also introduce dry surfactants in the post dosing step. Ungers Surfactants range of THONYL dry LAS qualities or UFAROL T dry FAS qualities are suitable for this purpose. Contact us for more information.
Spray drying is becoming more and more obsolete due to the energy inefficiency of spray drying and the shift in the market towards more compact formulations. These compact formulations are either made by modification of spray dried powders, high-shear agglomeration and in-situ neutralization process or dry blending.
In the high-shear in-situ neutralization process there is commonly challenging to adsorb all the liquid components to the builder matrix. To substitute parts of the LABSA (linear alkyl benzene sulfonic acid) with dry anionic surfactants may increase production output, improve flow and reduce lumping. One may also increase the content of liquid non-ionic surfactants without bleeding and wetting of the cardboard box. For more information contact us.
Dry blending is commonly for smaller scale production and in I&I applications. Unger surfactants range of dry products are perfect as primary anionic surfactant for this purpose.
