DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to thickened aqueous detergent compositions suitable for household application. More particularly, the compositions herein are suitable in hard-surface applications including toilet cleaning as well as in dishwashing applications, especially as a pretreatment composition.


BACKGROUND OF THE INVENTION

The liquid detergent compositions comprising the combination of long chain amine oxides and fatty acids are well known in the art.
It is desirable that such compositions have good cleaning properties. However, it has been found that long chain amine oxides do not provide the optimum cleaning performance. It is thus a first object of the present invention to provide cleaning compositions comprising long chain surfactants with improved cleaning.
In response to this object, it has been found that the incorporation of short chain surfactants is beneficial and meets this object thereby enhancing the cleaning performance. However, it has been observed that the incorporation of shod chain surfactants in such compositions results in the decrease of viscosity of the composition. Yet, it is considered essential that the compositions should exhibit a high degree of viscosity so that the compositions adhere to the vertical surfaces and surfaces inclined to the horizontal.
Thus, it is a further object of the present invention to provide a liquid composition which comprises long chain surfactants and short chain surfactants, which retains viscosity.
In response to this object, it has been found that viscosity may be retained even upon the addition of short chain surfactants, by the use of a specific mixture of amine oxides, more specifically a mixture of a C.sub.14 chain amine oxide with a C.sub.12 chain amine oxide, or a C.sub.16 chain amine oxide or mixtures thereof.
A further advantage of the present invention is that there is no need for an additional thickening agent. An additional advantage of the compositions of the present invention is that they have a desirable sudsing profile such that suds suppressers are not required.
Thickening compositions comprising long chain amine oxides and fully saturated fatty acids are well known in the art.
U.S. Pat. No. 4,282,109 discloses a thickened bleach composition comprising hypochlorite and linear and branched long chain C.sub.10 -C.sub.18 amine oxides as thickeners. There is no mention of short chain C.sub.6 -C.sub.8 surfactants or fatty acids.
EP 274 885 discloses thickened bleaching compositions comprising alkali metal hypochlorite and straight chain C.sub.14 amine oxide with a mixture of branched and straight chain C.sub.15 amine oxide. There is no mention of short chain surfactants. The compositions may optionally contain fatty acids as an additional thickening aid.
EP 233 666 discloses a process for the manufacture of a thickened bleaching composition comprising hypochlorite, a hypochlorite-soluble surfactant and an alkali metal salt of a fatty acid. The detergent actives include amine oxides, preferably lauryldimethylamine. There is no mention of short chain surfactants.
DE 28 37 880 discloses bleaching compositions comprising alkali metal hypochlorite and mixtures of branched and linear amine oxides of varying chain length, (C.sub.5 -C.sub.17) for increased viscosity. The compositions do not require fatty acids for thickening.
EP 30 401 discloses thickened bleaching compositions comprising hypochlorite and a certain number of product characteristics including pH and viscosity. Mixtures of C.sub.8 -C.sub.18 amine oxides and fatty acids are preferred as thickening agents. There is no mention of short chain surfactants.


SUMMARY OF THE INVENTION

The compositions of the present invention comprise aqueous compositions having a viscosity of from 50 cps to 2000 cps comprising a mixture of long chain amine oxides according to the formula R.sub.1 R.sub.2 R.sub.3 NO wherein R.sub.2 and R.sub.3 are independently C.sub.1 -C.sub.3 alkyl groups, and a short chain surfactant.
Said short chain surfactant comprises a hydrophobic portion
