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.
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.
2 ~ 1 ~ 15 2 9 y~ PCT/US94/10247 Particularly, the hands of the user are prone to such irritation. As a result of coming 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.
It is believed that 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 com.~w itions.
The presECa 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 C10-Clg and alkyl sulphate Cg-C12. 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 C14 amine oxide with a mixture of branched and straight chain C15 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 BBO covers bleaching compositions comprising alkali metal hypochlorite and mixtures of branched and linear amine oxides of varying chain length, (C5-C1~~ 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-Clg 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.
Summary of the Invention The present invention is directed to 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 R,RZR3N0, wherein R1 is a Cg to C18 alkyl group and Rz and R3 are independently Cl to C3 alkyl groups. Said alkyl sulphate is according to the formula R40SO,H, wherein RQ is a C6 to Clo alkyl group.
All amounts, ratios, percentages and parts herein are given as a % weight of the total composition unless otherwise stated.
.. 2171529 ~j 3a In a particularly preferred embodiment the invention is directed to a cleaning composition having reduced skin irritation, comprising:
a) a hypochlorite compound wherein the amount of active chlorine is from about 0.4% to about 5% of the composition; b) from 2o to about 5g of an amine oxide having the formula: R1RZR3N0 wherein R1 is C8-C,e alkyl; R~ and R3 are each independently C,-C3 alkyl; c) from about 1% to about 80 of an alkyl sulfate having the formula: RQOS03H
wherein R4 is C6-Clo alkyl; d) from about 0.5% to about 0.9% of an alkali metal salt of a CB-C18 fatty acid; and e) the balance carriers and adjunct ingredients.
