Abstract
The present invention is the use of sulphamic acid in a liquid acidic composition comprising another acid, for improved skin mildness.
Description
- The present invention is related to acidic hard-surfaces compositions, especially limescale removing compositions.
- Hard-surfaces cleaning compositions based on acids including strong acids and/or weak acids are known in the art. For instance limescale removing compositions are mainly based on strong and/or weak acids. However, such limescale removing compositions are perceived by the consumers as being amongst the most irritant detergent compositions. Indeed, many consumers suffer from skin irritation when using such compositions.
- Particularly, when using such acidic compositions the hands of the user are prone to irritation. This occurs when the compositions are used neat and also when used in diluted form.
- It is believed that the acids may attack the uppermost layer of the epidermal of the skin and alter the natural pH of the skin. This results in the decrease of the elasticity of the skin. The skin also becomes more sensitive, resulting in dryness and coarseness of the skin. In addition the skin may become inflamed and become red and sore and itchy.
- An object of the present invention is to improve skin mildness and reduce skin irritation of acidic compositions, especially acidic limescale removing compositions. Another object is to provide acidic limescale removing compositions which are milder to skin while exhibiting excellent limescale removing performance.
- The present invention overcomes these problems by the use of sulphamic acid in liquid acidic compositions suitable for descaling hard-surfaces. Indeed, it has now been found that by adding sulphamic acid, in a liquid composition comprising acids which are otherwise known to be irritant to the skin such as maleic acid, the skin mildness of said composition is improved. Indeed, less skin irritation is perceived by the user when its skin comes into contact with said composition.
- Limescale compositions comprising sulphamic acid are known in the art. EP-A-666 305 discloses acidic limescale removing compositions comprising maleic acid and a second acid like sulphamic acid. EP-A- 66 305 fails to disclose that sulphamic acid when added in a liquid acidic composition allows to improve the skin mildness of said composition and/or to reduce the skin irritation of said composition.
- The present invention is the use of sulphamic acid in a liquid acidic composition comprising another acid, for improved skin mildness.
- An essential ingredient in the present invention is sulphamic acid. Sulphamic acid may be added in the compositions according to the present invention in its acid form or as an alkali metal salts thereof. Thus sulphamic acid may be added for example as sulphamate. Sulphamic acid is commercially available under the trade name of Sulphamic acid by Albright & Wilson or Nissan chemicals.
- According to the present invention the compositions comprise from 0.1% to 20% by weight of the total composition of sulphamic acid, preferably from 0.1% to 10% and more preferably from 0.1% to 5%.
