Abstract
The present invention is an aqueous liquid detergent composition comprising a short chain surfactant for improved cleaning performance. Said composition further comprises a mixture of long chain amine oxides to restore viscosity. Said composition provides outstanding soil removal when used as a dish pretreatment composition as well as outstanding cleaning performance when used in hardsurface applications including toilet bowl cleaning.
Description
WO 95/03383 ~ PCT/US94/08089 THICKENED AQUEOUS DETERGENT COMPOSITIONS WITH IMPROVED CLEANING
PERFORMANCE WITH SHORT CHAIN SURFACTANTS
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 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 surtactants is beneficial and meets this object thereby enhancing the cleaning pertormance.
However, it has been observed that the incorporation of short chain surfactants in such compositions results in the WO 95/03383 ~ ~ ~ ~ PCTILTS94/08089 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 surtaces 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 surtactants, which retains viscosity.
In response to this object, it has been found that viscosity may be retained even upon the addition of short chain surtactants, by the use of a specific mixture of amine oxides, more specifically a mixture of a C14 chain amine oxide with a C12 chain amine oxide, or a C16 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.
US 4 282 109 discloses a thickened bleach composition comprising hypochlorite and linear and branched long chain C10-C1 g amine oxides as thickeners. There is no mention of short chain C6-C8 surtactants or fatty acids.
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 surtactants. 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 hypochlor'tte-soluble surtadant and an alkali metal salt of a fatty acid.
The detergent actives inGude 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, (C5-C1 ~ 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 Cg-C1g amine oxides and fatty acids are preferred as thickening agents. There is no mention of short chain surtactants.
