  • the present invention relates to the field of cleaning compositions.
  • the present invention relates to a cleaning composition comprising water, xanthan gum and one or more surfactants and wherein the composition has an alkaline pH of about 13.1 or above.
  • the present invention does also relate to containers comprising such composition, as well as methods and uses of said composition.

  • One of said properties can be a relatively high viscosity to ensure continued contact with and adherence to the surface to be cleaned.
  • Such cleaner should preferably be easy to remove after having exerted its cleaning activity, i.e. strong contact with the surface is no longer desired.
  • application of the cleaner to the respective surface should be convenient and safe for the person applying it. This can be an issue, as a large number of cleaning agents is very alkaline in nature. The reason is that hydrolysis, chelation and dispersion of soil are typically achieved best under alkaline conditions.
  • conventional oven cleaners can have a pH of 13 or above. Meeting all these diverse requirements may pose a significant challenge to the person skilled in the art.
  • xanthan gum in a highly alkaline cleaning composition generates a versatile cleaning composition. This is surprising as xanthan gum is considered by the person skilled in the art to be stable only in a pH range of 1 to 11 (see for example Roempp online database; entry on Xanthan, Thieme).

The addition of xanthan gum into the water was done very slowly with strong stirring (1500 rpm) and a deflocculating pale. The mixer speed was reduced as viscosity developed to avoid air entrapment. The hydration took around 45min at room temperature. In parallel, a sodium hydroxide solution was prepared and surfactants were added to the sodium hydroxide solution. Finally, the 2% aqueous stock solution of xanthan gum was added to the alkaline surfactant solution and the resulting solution stirred for at least 1 hour at room temperature. Thereafter, the solution was allowed to form a gel.
