Hudson, Alice, Surface Chemists of Florida, US Patent No. 9,856,436, January 2, 2018.

Surface Chemists of Florida, Inc. has patented modified soy protein laundry additives that are derived from soy flour with minimal processing and waste streams, thus allowing production of economical additives that may provide soil antiredeposition, dye transfer inhibition, soil repellency, and fabric wear reduction in household and I&I laundry products.

The use of renewable sources of raw materials for producing chemical materials for applications in wide ranging industrial and consumer products is important for a sustainable future. The use of naturally derived biodegradable raw materials to produce additives for use in consumer products – especially materials utilizing processes that generate minimal waste streams – greatly enhances the ongoing sustainability efforts of detergent manufacturers and supports the principles of green chemistry.

There has long been a need for laundry additives that are 1) biodegradable and bio renewable, 2) produced sustainably with minimum processing steps and low waste production, 3) processed with very minimal solvent use, 4) compatible with surfactant systems commonly found in laundry products, and 5) economically effective in today’s global market.
The new SCF protein technology delivers all these sustainability benefits and can provide the following performance enhancements in laundry detergents:

  • The modified proteins prevent the redeposition of soils from the wash liquor that lead to greying of
    laundered materials.
  • They may also prevent dye transfer from garment to garment in the wash.
  • Additionally, the new materials can provide soil repellency to laundered fabrics.
  • They may provide a lubricated surface on the fabric that decreases fabric abrasion and pilling.
