Claims (1)

1. The claims defining the invention are as follows:

   This invention relates to detergents.

   It is known that the leaves of many plants have some deter-

   gent properties when crushed in the hand and moistened. Usually

   the detergent property is not marked and is frequently accompan-

   ied by a staining action caused by vegetable dyes in the leaves;

   :sometimes too, contact with the leaves or their juices can cause

   severe irritation to the human skin.

   It has been found that leaves of certain plants possess the

   S..10 detergent property in a marked degree yet do not irritate human

   skin and after suitable processing do not have a staining action.

   The plants to which the invention is applicable include

   members of the family Myrtaceae, more especially the genus

   Eucalyptus. The following species of the genus Eucalyntus have

   been found to be especially suitable: E. obliqua, E.dives,

   E, radiata, E. ovata, E. viminalis, E. regnans, E. citriodora.

   In suitable conditions mature trees of these species give

   high yields of leaves. After felling mature trees of these species

   there is often a vigourous regrowth from the stump that gives a

   high yield of leaves in a form suitable for mechanical harvesting.

   The material made by the process produces very efficient det-

   ergent solutions which are non-foaming, readily bio-degradable,

   pleasant smelling and non-staining. Further there are indications

   that the material is fungistatic and bacteriostatic. No undesirable

   effects on human skin have been noted indeed there may be some

   beneficial soothing effects.

   The process of the invention will now be more fully described.

   It is preferred that only mature, healthy leaves from the

   trees .efined above are used.

   .Aftor harv, sting of the leaves it is preferred that the leaves

   I-9- be withered under cover protected from rain and hot sun and then oven dried.

   Withering prior to oven drying is regarded as important

   because if the green leaves were placed directly in an oven to

   dry them volatile substances in the leaves will be lost and the

   resultant material has been found to have poorer detergent

   properties. Of course the amount of time taken fcr sufficient

   withering in air depends upon the climatic conditions at the

   time. For instance, during hot dry weather in Victoria a wither-

   ing period of say 48 hours is usually sufficient. During cold,

   wet weather, however, withering will be much slower and some art-

   ificial heat may be necessary but the temperature of the leaves

   at this stage should not exceed 40 deg C and air ventilation

   speed should not be high, a velocity of about 5 km per hour

   being preferred.

   After withering the leaves are dried for approximately 1 hour

   in an oven temperature of not more than 60 deg C otherwise the

   leaves will be scorched.

   After oven drying the leaves are ground or hammermilled and o* e 20 then passed through a fine sieve with about 225 meshes to the

   sq cm to produce a fine pewder. Any residue on the sieve is

   reground till it passes the sieve.

   The powder produced by the process above may be simply

   added to water to produce a detergent solution as required. For

   instance 5 ml of the powder may be well mixed into about

   1 of hot water to produce a very effective domestic detergent

   solution which is quite suitable for washing household dishes,

   glass and cutlery either manually or in a dishwashing machine.

   Alternatively a concentrated, stock detergent solution may

   be made from the powder by boiling 28 g in 568 ml of water for

   I" about 5 minutes and straining off the clear liquid. It has been found that the addition of 1 ml acetic acid to the mixture of powder and water befare boiling adds to the effectiveness of the product as a detergent and improves its shelf life.

   This stock solution is light brown in colour and has a

   pleasant odour. Addition of 10 ml of this stock solution

   to about 5 1 of hot water produces a detergent solution

   suitable for domestic purposes such as dish washing.

   Many variations are possible in the process described

   above without departing from the spirit and scope of the

   no invention.
