Definitions
- the present invention relates to an aqueous bleaching composition suitable for laundry and general domestic bleaching and disinfecting purposes. More particularly, it relates to an aqueous bleaching composition which also contains a synthetic detergent which is soluble in the composition thereby to impart a foaming capacity to the composition.
- the preferred bleaching agent is alkali metal hypochlorite.
- Such an aqueous alkali metal hypochlorite composition comprising a foam-imparting synthetic detergent is known in the art, e.g. from British Patent Specification 886,084. This specification describes inter alia the use of betaine-type quaternary ammonium detergent surfactants in aqueous alkali metal hypochlorite compositions.
- foam-imparting synthetic detergents are the trialkylamine oxides, containing one C12-C18 alkyl group and two C1-C3 alkyl groups.
- compositions while having the required foaming characteristics, present a problem, however, in that, during manufacture and packing of the composition the foaming of the composition makes it difficult to fill the containers properly; the composition foams out of the bottle, resulting in messy bottles which are not filled with the proper filling weight.
- the invention provides a process for the production of an aqueous bleaching composition
- an aqueous bleaching composition comprising an aqueous mixture of a bleaching agent and a foaming synthetic detergent, characterised by including a foam-depressing agent which is not stable in the mixture, packing the composition in containers while the foam-depressing agent remains effective, and optionally then storing the containers.
- the invention provides a bleaching composition obtainable by including a foam-depressing agent in an aqueous mixture of a bleaching agent and a foaming synthetic detergent, which foam-depressing agent is not stable therein, packing the composition in containers while the said foam-depressing agent remains effective, and optionally then storing the containers.
- composition in the containers will change during storage. Initially it will be temporarily low-foaming or non-foaming, with a latent foaming property. As time passes the foam-depressing agent is replaced by products of its decomposition and the foaming property will appear.
- this invention provides an aqueous bleaching composition
- a bleaching agent a foaming synthetic detergent and an additional component which is
- the invention extends of course to containers of the bleaching composition.
- a preferred feature made possible by this invention is that the containers are filled substantially full with the composition.
- the foam-depressing agent must be unstable in the composition.
- Foam-depressing agents which have been found very effective are silicones (more correctly polysiloxanes). These may be used in an amount which is at least 0.001% by weight of the composition. Amounts greater than 0.01% by weight will normally not be necessary, although amounts somewhat in excess of this may be used if desired, for instance up to 0.5% by weight of the composition.
- Polysiloxanes which can be employed as antifoam agents have the structure wherein R and R′, which may be the same or different, are alkyl or aryl groups having from 1 to 6 carbon atoms; and x is an integer of at least 20.
- the preferred polysiloxanes are polydimethylsiloxanes where both R and R′ are methyl groups. Usually the molecular weight is from 500 to 200 000.
- the composition will generally contain from 1 to 15% by weight of the bleaching agent.
- the preferred bleaching agent is alkali metal hypochlorite, for example sodium hypochlorite.
- Other bleaching agents may be used, for example hydrogen peroxide.
- the time taken for the composition to regain its foaming properties will of course depend on the rate of reaction between the bleaching agent and the silicone. Thus, hydrogen peroxide would take somewhat longer than a like amount of hypochlorite to degrade the silicone but this merely necessitates some increase in the time for which the composition is stored after packing.
- the synthetic detergents preferably used in this invention are amine oxides, more preferably trialkyl amine oxides in which one alkyl group has from 8 to 20 carbon atoms while the other two have from 1 to 4 carbon atoms.
- An example is lauryl dimethyl amine oxide.
- the amount of surfactant included in the composition typically lies in the range from 0.05 to 1.5% by weight of the composition. Amounts somewhat greater than 1.5% by weight may be used if desired, for instance up to 5% by weight.
- composition usually contains free alkali to provide a required alkaline pH.
- Other additives can be included, such as perfumes and colouring agents.
- compositions were assessed by shaking a quantity of each composition in accordance with a standardised procedure and then observing the height of foam generated.
- the compositions were analysed for residual bleaching agent after a period of storage. These test results are included in the Table below.
