Abstract
ABSTRACT
This invention provides a novel disinfectant composi-tion which is an aqueous solution containing hypochlorite ions, such as sodium hypochlorite, containing a tertiary al-iphatic alcohol, such as tertiary-butanol. The alcohol acts as an odour masking agent and as a stabilizer for hypochlor-ite ions while itself possessing disinfecting properties.
The composition is useful as a disinfectant.
This invention provides a novel disinfectant composi-tion which is an aqueous solution containing hypochlorite ions, such as sodium hypochlorite, containing a tertiary al-iphatic alcohol, such as tertiary-butanol. The alcohol acts as an odour masking agent and as a stabilizer for hypochlor-ite ions while itself possessing disinfecting properties.
The composition is useful as a disinfectant.
Description
~ ~.55~0 This invention relates to a novel disinfectant compo-sition and more particularly it relates to a novel disinfec-tant composition containing hypochlorite ions.
It is known that chlorine-based disinfectants such as those containing hypochlorite ions, for example sodium hypo-chlorite, are useful in destroying pathogens such as bacter-ia. These disinfectants suffer from the disadvantage that they have an offensive odour of chlorine and potential users of such disinfectants object to the smell of chlorine and thus such disinfectants tend not to be the disinfectant of choice.
We have now found, and herein lies our invention, that the offensive odour of an aqueous solution containing hypo-chlorite ions can be reduced by the addition of a particular odour masking ingredient.
According to the invention, as claimed herein, there is provided a novel aqueous solution containing hypochlorite ions wherein there is present a tertiary aliphatic alcohol.
As an example of an aqueous solution containing hypo-chlorite ions there may be mentioned an aqueous solution con-taining an alkali metal or an alkaline earth metal hypochlor-ite such as lithium, sodium, potassium, calcium or barium hypochlorite. The hypochlorite compound may be present to an extent of up to about 2% w/w of the solution. A preferred hypochlorite is sodium hypochlorite which may be present in a concentration of 0.5% w/w.
The tertiary aliphatic alcohol present in the novel aqueous hypochlorite solution may be a tertiary alcohol con-taining from 4 to 8 carbon atoms such as tertiary-butanol, 2,3-dimethyl-2,3-butanediol or 2,4-dimethyl-2,4-pentanediol.
Of these tertiary aliphatic alcohols, a preferred alcohol is tertiary-butanol. The presence of a tertiary aliphatic alco-3~
- 2 _ 1Z~55,'~
hol is advantageous in that it not only acts as an odour mask-ing agent but it also has biocidal activity in possessing mild disinfectant properties and it additionally functions as a sta-bilizer for hypochlorite ions.
As a further preferred feature of the invention there is provided an aqueous solution containing a compound provid-ing hypochlorite ions, such as sodium, potassium, lithium or calcium hypochlorite, in the presence of a tertiary aliphatic alcohol, such as tertiary-butanol, 2,3-dimethyl-2,3-butanediol or 2,4-dimethyl-2,4-pentanediol, wherein for each 1 part by weight of said compound there is present from about 2 parts by weight to about 30 parts by weight of tertiary aliphatic alcohol, preferably from about 5 parts to about 15 parts by weight of tertiary aliphatic alcohol.
For example, an aqueous solution containing 1 part by weight of sodium hypochlorite may have present therein from about 2 parts by weight to about 30 parts by weight, prefer-ably from about 5 parts to about 15 parts by weight, of ter-tiary-butanol, 2,3-dimethyl-2,3-butanediol or 2,4-dimethyl-2,4-pentanediol. A particularly useful aqueous solution is one containing about 1 part by weight of sodium hypochlorite and about 10 parts by weight of tertiary-butanol, 2,3-dimethyl-2,3-butanediol or 2,4-dimethyl-2,4-pentanediol.
The aqueous solution containing hypochlorite ions may optionally have present therein one or more additional in-gredients. Thus, for example, the aqueous solution may also contain a synthetic organic detergent, such as sodium dodecyl sulphate. Thus, for example, for each part by weight of com-pound providing hypochlorite ions, such as sodium hypochlor-ite, there may be present from about 0.005 to about 0.1 part by weight, preferably about 0.02 part by weight, of synthetic organic detergent, such as sodium dodecyl sulphate.
The aqueous solution containing hypochlorite ions may also optionally have present therein one or more chlorine 55~;0 stable fragrances, such as a lemon fragrance or a pine frag-rance. Such fragrances may be present in an amount such that for each part by weight of hypochlorite compound there is present from about 0.005 to about 0.2 part by weight of frag-rance, preferably about 0.02 part by weight of fragrance, preferably a lemon fragrance.
The amount of fragrance may vary according to the strength and volume of the fragrance used. A weaker frag-rance may be present to an extent of 0.2% w/w whereas a stronger fragrance may be present to an extent of 0.02~ w/w.
The synthetic organic detergent, such as sodium dodecyl sul-phate, not only provides a cleaning power to the disinfec-tant but it also helps to dissolve or maintain the fragrance in solution. Since suitable fragrances mentioned above are usually oil-based fragrances, the synthetic organic deter-gent may be used to dissolve the fragrance prior to addition to the aqueous solution and thereafter it maintains the frag-rance in solution. When a fragrance is present to an extent of from about 0.005 to about 0.2~ w/w, the range of detergent may generally be from about 0.005 to about 0.01~ w/w. Quan-tities of detergent in excess of this amount may be present to provide additional detergency to the solution.
Other optional ingredients may be present in the novel aqueous solution of the invention such as a chlorine stable colouring agent.
The novel aqueous solutions of this invention are use-ful in destroying pathogens including viruses, bacteria and fungi.
The invention is illustrated by, but not limited by, the following Examples in which the ingredients are given as percentages of parts by weight.
