Definitions
- This invention relates to detergent bars.
- antioxidants frequently used act by absorbing free radicals and thus terminate chain reactions independently of the method of initiation. in this process, the antioxidant is itself destroyed. Thus it is desirable to include a sequestering agent to lower the rate of initiation of free radicals. Inaddition to the sequestering agent another antioxidant is often included to absorb free radicals'initiated by any residual metal ions, or by photochemical or thermal energy sources.
- a particular problem is the prevention of deterioration of'base odour, spotting and discoloration in super-fatted detergent bars, for example, in soap bars containing significant amounts of free fatty acid.
- a typical super-fatted soap contains 10% (calculated -as a percentage of the total fatty matter) of free fatty acids but soaps containing 20% of free fatty acid are known.
- the presence of metal ions, particularly iron and copper ions, in these soaps can be particularly troublesome: Petrolatum, mineral oils, lanoline or other such super-fatting agents can be used as well as fatty acids added separately or specially released in the bar.
- a super-fatted non-soap detergent bar can contain as glycols, fatty acid amides, long-chain alkanolamides, in
- EHDP diphosphonic acid
- EDTA ethylene-diaminetetraacetic acid
- the EHDP, the EDTA or bo may be in the form of their esters or, preferably, in the form of their salts.
- Particularly preferred salts are the alkali-metal, ammonium or triethanolammonium,salts.
- the invention provides a detergent bar containing a' synergistic mixture of EHDP and EDTA.
- EHDP and EDTA used will depend to some extent on the particular detergent used but bars according to the invention can be provided by incorporating as little as 0.005% of EHDP in admixture with as little as 0.005% of EDTA.
- the quantity of EHDP will, in general, be from 0.005% to 0.3% or even higher and that of EDTA 0.005 to 0.3% or higher.
- a preferred detergent bar according to the invention contains between 0.01% and 0.08% EHDP and 0.01% and 0.08% EDTA by weight.
- a particularly preferred detergent bar according to the invention contains about 0.02% EHDP and about 0.02% EDTA by weight.
- the invention is particularly applicable to toilet bars for personal washing.
- the invention is even more particularly applicable to super-fatted toilet bars for personal washing. In such bars deterioration in odour and colour is least welcome and the effect of metal ions is most acute as explained above.
- the invention is particularly applicable to a detergent bar in which the detergent is soap, it will be appreciated that the invention is applicable to any detergent bar that contains an ingredient that contains a long-chain fatty residue. Such ingredients are liableto cause the odour and colour of the bar to deteriorate when metal ions, particularly copper and iron, are also present.
- an ingredient that contains a long-chain fatty residue is meant a compound containing a C to C preferably C to C group.
- the chain may be branched but should preferably be straight.
- the compound will normally contain functional groups, as illustrated below.
- the C to C group may contain one or more double bonds.
- the invention is, for example, applicable to detergent bars containing, as major active, such non-soap detergents as olefin sulphonates (prepared by the sulphonation of olefins followed by hydrolysis and neutralisation), fatty acyl isothionates, fatty acyl taurides and fatty alcohol sulphates.
- non-soap detergents as olefin sulphonates (prepared by the sulphonation of olefins followed by hydrolysis and neutralisation), fatty acyl isothionates, fatty acyl taurides and fatty alcohol sulphates.
- the invention is also applicable to bars containing mixtures of soap and non-soap detergents.
- the invention is applicable to bars containing a major proportion of a non-soap detergent together with a minor proportion of soap.
- Non-superfatted bars large batch of dried soap chips, manufacture from 30% Tallow/20% Palm Kernel Oil fat charge, was 'oughly mixed to ensure homogeneity. Special precaus were taken to minimise metallic contamination in chips.
- the batch was sub-divided into 16 sub-batches to each of 15 of these .was added fixed quantities of lution of EDTA and/or a solution of EHDP. In this 16 batches were obtained with all possible combinas of any one of 4 levels of EDTA (0, 0.03, 0.12 or with any one of 4 levels of EHDP (0, 0.03, 0.12 0.48%).
- he ratio of copper/iron chosen approximates to the age ratio found in practice. Up to 1 p.p.m. copper 10 p.p.m. iron are frequently found in practice.
- Base level of copper 0.3 p.p.m.
- Base level of iron 4.6 p.p.m.
- Non-superfatted bars A large batch of dried soap chips, manufactured from an tallow/20% palm kerneloil fat charge was thoroughly mixed to ensure homogeneity. Special precautions were taken to minimise metallic contamination in the chips. The batch was sub-divided into 30 sub-batches;
