Definitions

  • the present invention is related to improve the skin mildness of hypochlorite-based compositions.
  • hypochlorite is an irritant and many consumers suffer from skin irritation when using such compositions.
  • the hands of the user are prone to such irritation.
  • the hands suffer from dryness and from a feeling of tightness. This occurs when the compositions are used neat and also when used in diluted form.
  • hypochlorite attacks the uppermost layer of the epidermal 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. These effects are magnified in alkaline conditions, because alkali is also an irritant. Alkalinity is required for hypochlorite stability and it thus the preferred condition for hypochlorite-comprising compositions. However, alkaline conditions contribute to skin tightening because it alters the natural pH of the skin.
  • the object of the present invention is to improve skin mildness and reduce skin irritation of hypochlorite-comprising compositions.
  • the present invention overcomes these problems by the use of the combination of amine oxides and specific alkyl sulphates in hypochlorite-comprising compositions. It is believed that this surfactant combination wets the skin and provides a protective layer against hypochlorite and alkalinity on the skin.
  • EP 274 885 discloses thickened bleaching compositions comprising alkali metal hypochlorite and straight chain C 14 amine oxide with a mixture of branched and straight chain C 15 amine oxide. There is no mention of short chain surfactants or the reduction of hypochlorite related skin irritation.
  • EP 233 666 discloses a process for the manufacture of a thickened bleaching compositions comprising hypochlorite, a hypochlorite-soluble surfactant, including amine oxide and an alkali metal salt of a fatty acid. There is no mention of the reduction of hypochlorite related skin irritation.
  • DE 28 37 880 covers bleaching compositions comprising alkali metal hypochlorite and mixtures of branched and linear amine oxides of varying chain length, (C 5 -C 17 ) for increased viscosity. There is no mention of other long or short chain surfactants or the reduction of hypochlorite skin irritation.
  • EP 30 401 covers thickened bleaching compositions comprising hypochlorite and a certain number of product characteristics including pH and viscosity. Mixtures of C 8 -C 18 amine oxides and fatty acids are preferred as thickening agents. No other surfactants are disclosed. There is also no mention of reducing the irritation effects due to the hypochlorite.
  • EP-A-635568 and WO95/03383 disclose short chain surfactants.
  • the present invention is the use of the combination of 1-5% amine oxide with 1-8% alkyl sulphate to improve skin mildness of hypochlorite-comprising compositions comprising 0,4-5% hypochlorite.
  • Said amine oxide is according to the formula R 1 R 2 R 3 NO, wherein R 1 is a C 8 to C 18 alkyl group and R 2 and R 3 are independently C 1 to C 3 alkyl groups.
  • Said alkyl sulphate is according to the formula R 4 OSO 3 H, wherein R 4 is a C 6 to C 10 alkyl group.
  • the present invention is the use of the combination of an amine oxide and an alkyl sulphate to improve skin mildness of hypochlorite-comprising compositions.
  • hypochlorite an essential ingredient in the present invention is hypochlorite.
  • the hypochlorite is an alkali metal hypochlorite.
  • alkali metal hypochlorites are preferred other hypochlorite compounds may also be used herein and can be selected from calcium and magnesium hypochlorite.
  • the compositions comprise said hypochlorite compound such that the content of active chlorine in the composition is from 0.4% to 5%, preferably from 1% to 4%, most preferably from 1% to 3%.
  • Another essential ingredient is a combination of an amine oxide with an alkyl sulphate to improve skin mildness of the composition.
  • Said amine oxide is according to the formula R 1 R 2 R 3 NO, wherein R 1 is a C 8 to C 18 alkyl group and R 2 and R 3 are independently C 1 to C 3 alkyl groups.
  • R 1 is a C 10 -C 18 , more preferably C 12 -C 18 alkyl group and R 2 and R 3 are preferably independently C 1 -C 3 , more preferably C 1 -C 2 alkyl groups.
  • the composition comprises from 1% to 5%, more preferably from 1.5% to 4.5%, most preferably from 2% to 4% of said amine oxide and mixtures thereof.
  • Said alkyl sulphate is according to the formula R 4 OSO 3 H, wherein R 4 is a C 6 to C 10 , preferably a C 7 -C 9 , more preferably a C 8 alkyl group.
  • R 4 is a C 6 to C 10 , preferably a C 7 -C 9 , more preferably a C 8 alkyl group.
  • the composition comprises from 1% to 8%, more preferably from 1.5% to 7.5%, most preferably from 2% to 7% of said alkyl sulphate and mixtures thereof.
  • compositions may further comprise a number of additional ingredients.
  • Suitable optional ingredients include other hypochlorite-compatible long chain surface actives including alkyl sarcosinates, alkyl ether sulphates, paraffin sulphonates and amine oxides.
  • Another optional component of the present invention is an alkali metal salt of a C 8 -C 18 fatty acid.
  • Suitable fatty acids for use herein can be any C 8 -C 18 fatty acid, preferably fully saturated, preferably a sodium, potassium or lithium salt, more preferably the sodium salt.
  • compositions have a pH greater than 10, preferably greater than 11, more preferably greater than 12. This is achieved by the addition of from 0.8% to 1.5% of a caustic alkali.
  • Suitable caustic alkalis for use herein include sodium and potassium hydroxide.
  • composition may also comprise a number of other additional ingredients such as hypochlorite stable and soluble colourants, perfumes and hydrotopes such as sodium xylene sulphonate.
  • compositions are prepared by methods known in the art such as those described in GB 1 329 086.
  • the compositons may be used for a variety of purposes, such as bleaching and hard surfaces cleaning.
  • compositions can be illustrated by the following examples.
