  • Patent number: 8518167
    Abstract: Described is a polish product, and particularly to a shoe or leather care product, in the form of a paste. The product is essentially free of volatile components (organic components as well as water). It comprises a wax component in an amount in the range of from 20-60%, a non-aqueous, non-volatile liquid component, wherein non-volatile is defined as not being an organic volatile substance having a vapor pressure of greater than 1 torr (0.13 kPa), in an amount in the range of from 20-60%, and a fatty component, preferably a fatty acid, in an amount of 1 to 40 wt %, preferably 5-15% all percentages being weight percentages based on total shoe care product.
    Type: Grant
    Filed: July 25, 2008
    Date of Patent: August 27, 2013
    Assignee: S. C. Johnson & Son, Inc.

  • Patent number: 7229486
    Abstract: The invention provides a water-based low VOC shoe and leather care product having good product properties and characteristics, which can be formulated by making an appropriate and careful selection of ingredients and their amounts. A shoe and leather care product according to the invention has been found to give results in the treatment of leather (shoes) closely resembling the results found when using a conventional, high VOC shoe care product. Furthermore, such favourable results can be achieved while significantly reducing the amount of organic solvents in the product.
