The present invention is the use of the combination of an amine oxide and an alkyl sulphate in hypochlorite-comprising compositions for improved skin midlness.
Description
USE OF HYPOCHLORITE-COMPRISING COMPOSITIONS FOR IMPROVED MILDNESS TO THE SKIN
Field of the Invention
The present invention is related to hypochlorite-based compositions.
Background of the Invention
The present invention relates to hypochlorite-comprising compositions. It is highly desirable to incorporate hypochlorite in detergent compositions for bleaching. However, hypochlorite is an irritant and many consumers suffer from skin irritation when using such compositions.
Particularly, the hands of the user are prone to such irritation. As a result of co ing into contact with such compositions 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.
7- is believed that hypochlorite attacks the uppermost layer 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 f 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.
Amine oxides and alkyl sulphates are known in the art. US 4 282 109 discloses a thickened bleach composition comprising hypochlorite and a thickening amount of a surfactant blend, comprising amine oxide Cιo~c18 anc* alkyl sulphate Cg-Ci2- There is no mention of the reduction of hypochlorite related skin irritation of these compositions.
EP 274 885 discloses thickened bleaching compositions comprising alkali metal hypochlorite and straight chain C]_ amine oxide with a mixture of branched and straight chain C]_5 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, (C5-C17) 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 Cg- C18 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.
Co-pending European application Nos. 93202187.6 and 93202186.8 disclose short chain surfactants.
Summary of the Invention
The present invention is the use of the combination of an amine oxide with an alkyl sulphate in hypochlorite- comprising compositions for improved skin mildness. Said amine oxide is according to the formula R1R2R3NO, wherein Ri is a Cg to Cig alkyl group and R2 and R3 are independently C]_ to C3 alkyl groups. Said alkyl sulphate is according to the formula R4OSO3H, wherein R4 is a Cg to C]_Q alkyl group.
All amounts, ratios, percentages and parts herein are given as a % weight of the total composition unless otherwise stated.
