Definitions

• This invention relates to cleaning compositions, such as detergents and soaps, suitable for use in the cleaning of and removal of stains from fabrics, natural and synthetic fibres, plastics, metals and many other materials.
• the present invention provides a cleaning composition
• a cleaning composition comprising a surfactant component and a terpene component consisting essentially of cineole substantially free of phellandrene.
• cineole is a particularly effective stain removing or dispersing aid which at the same time is particularly well tolerated by the skins of most people.
• This latter feature is particularly important in practice because in many situations hand washing is the most convenient cleaning method for removing stains.
• This feature also allows the possibility of using the cleaning composition for removing stains from the hands.
• substantially pure cineole e.g. cineole BPC is used though in general cineole containing up to the order of 50% of other non-harmful terpenes may be used.
• cineole BPC and cineole containing up to 10% w/w of terpenes such as ⁇ -pinene and p-cymene and up to,20 or 30% w/w of terpenes such ast ⁇ -ter- pineol may be used.
• Other aromatic compounds may also be tolerated in relatively small amounts depending on their degree of innocuousness.. Thus small amounts e.g.
• phenolic compounds may be present though preferably the cineole.is substantially free of phenolic compounds.Although even lower proportions of cineole could be used this would normally be less desired since it would generally require the use of a larger amount of the terpene component in order to maintain the cleaning power of the composition.
• cineole has been found to be particularly effective when used in cool or cold water thereby minimizing the risk of 'setting' of the stain which may occur when hot or even warm wash solutions are used.
• Yet another significant advantage that may be obtained with the present invention is that surfaces which have been cleaned with a cleaning composition of the present invention exhibit a significant repellent effect on pests such as cockroaches, which has not been previously found with other terpene containing cleaners, thereby making the cleaning compositions particularly useful in shipboard and catering situations.
• the cleaning compositions may be used by itself if desired either undiluted or diluted in a washing or cleaning medium such as water. More conveniently though the cleaning composition of the invention is used as an additive composition which is incorporated in a more or less conventional cleaning agent such as a soap or detergent composition.
• the cineole may be used in various proportions to the other constituents in the cleaning composition depending inter alia on the nature of the other constituents, the constituents of any cleaning agent into which the composition is intended to be incorporated, and the materials to be cleaned e.g. metal or fibre, and in certain cases the nature of the stain material.
• the cineole preferably comprises from 0.1 to 70% v/v of the cleaning composition, preferably from 3 to 70% in the case of an additive compos- i tion with the higher concentrations being preferred in the Case of additives for detergents and the lower ones in the case of additives for soaps.
• additive compositions these may be incorporated in any convenient proportion relative to the detergent, or soap, for example at from 0.1 to 35% by volume, preferably at about 3% by volume.
• the present invention provides a cleaning composition
• a cleaning composition comprising a surfactant component and a terpene component comprising cineole substantially free of phellandrene, the cineole constituting from 0.1 to 70% v/v, preferably from 0.3 to 70% v/v, most preferably from 0.3 to 50% v/v, of the composition, preferably the terpene component does not contain any phellandrene.
• the cineole used may be either synthetic cineole (e.g. obtained by conversion of other terpenes having similar structures, for example from(X - terpineole)or natural cineole obtained from certain cineole - containing eucalyptus species such as E. (Eucalyptus) Polybracteata, E. Smithii, E. Globulus, E. Viridis, E. dives "var" C, E. Australiana, E. Elaeophora, E. Sideroxylon, E. Leucoxy- lon, E. Cineorifolia, and E. dumosa, which generally contain 70% or more cineole, by recovery e.g.

• cineole-containing cajuput oil sources such as the narrow-leaved forms of certain Melaleuca species e.g. M. Caujuputi and M. Leucadendron (Myrtaceae) or solvent extraction from the natural oils obtained therefrom.
• synthetic forms of the natural oil "mixtures” e.g. commercially available synthetic cajuput oil BPC obtainable from, for example 1 but using a synthetic cajuput oil obtained from Zimmerman Hobbs Ltd. of Milton Keynes, England in place of the substantially pure cineole component.
• the cineole used is not less than 95%, most desirably not less than 99% v/v pure, free of phellandrene, and contains not more than 1% of other terpenes.
• the cineole may conveniently be employed as a solution, for example, in an aliphatic alcohol, preferably a lower alkyl alcohol, for example ethanol or methanol, conveniently in the form of methylated spirits.
• an aliphatic alcohol preferably a lower alkyl alcohol, for example ethanol or methanol
• the cineole is used as a from 30 to 90% v/v solution, preferably a 40% v/v solution, especially in the case of a methylated spirits solution.
• the methylated spirit is solvent itself contributes to the stain removing properties of composition.
• the surfactant component may comprise one or more of any suitable surfactant including anionic, cationic or nonionic surfactants; suitable surfactants which may be mentioned include sodium dodecylbenzene sulphonate such as the form commercially available from Albright & Wilson of Whitehaven, England, under the Trade Name “Nansa”, or sodium lauryl ether sulphate or sodium lauryl sulphate also available from Albright & Wilson under the Trade Name "Empiynin”.
• an emulsifying and foam stablising agent that is a stain softening agent such as a lauric acid diethanolamide.
• a stain softening agent such as a lauric acid diethanolamide.
• This may conveniently be in the form of l:l coconut oil diethanolamide, coconut oil containing some 48% lauric acid.
• Such materials are readily available commercially e.g. from Albright &, Wilson of Whitehaven, England, under the Trade Name EMPILAN.

• soap and detergent compositions may be employed in any conventional form including soap tablets, flakes and powder and liquid detergent and concentrate. Whilst the invention extends to an additive composition suitable for incorporation in a conventional soap detergent, or hand cleaning gel or cream, the composition of the invention may be used in its concentrate form or merely diluted in water.
• composition of the invention may be made by bringing the cineole and surfactant components into intimate a mixture with each other, and with any other ingredients, that may be required. Where a softening agent is used this is desirably added after any alkali metal salt has been added to the cineole surfactant mixture.
• the resulting composition is then suitable for use as an additive for incorporation in a soap base comprising generally alkali metal hydroxide, water, and a fatty acid component such as beef tallow and coconut oil, or in a detergent optionally with water, to form an intimate blend therewith.
• composition was made from the following ingredients:
• An additive composition was prepared from the following ingredients:
• the surfactant (20 mls) was added to the cineole solution (100 mls) and thoroughly mixed therewith. After standing for 5 minutes the softening agent (30 mls) was added and mixed in. The resulting additive composition was a clear liquid (150 mls).
• a conventional soap composition was made up by dissolving caustic soda (Na OH 30 g) in water 20 mls and progressively brought into admixture with natural fatty acids in the form a blend of beef tallow (80% w/w) and coconut oil (20% w/w) (30 g) and stirred and boiled. After separation of the residual lye, additive composition (2.0 mls) prepared according to Example 2 was mixed in thoroughly the resulting mixture then being compressed in a mould to form a soap tablet.
