The composition of the invention is particularly, though not necessarily exclusively suitable for mixing fuel oils and water to form a solution.
Even more particularly, the composition is suitable for mixing diesel fuel oil and water to form a clear solution. The composition may thus be used as an additive to diesel fuel oil.
Unless otherwise indicated, all concentrations are given on a percentage by mass (mass%) basis.
The composition according to the second aspect of the invention may also include a non-ionic ethoxylated sorbitan ester.
The sorbitan ester may be present in the composition in a concentration of from 12% to 58% by mass. Preferably, the sorbitan ester is present in the composition in a concentration of from 24% to 46% by mass. Most preferably, the sorbitan ester is present in the composition in a concentration of from 29% to 41 % by mass, e.g. 35% by mass. The sorbitan ester may have a hydrophile-lipophile balance value (HLB value) in the range of 16.4 - 16.7. An example of a suitable non-ionic ethoxylated sorbitan ester is Polysorbate 20 (Trademark), which is available in South Africa from Croda Chemicals (SA) (Pty) Limited of 4 Lovora Street, Jetpark.
The alcohol ethoxylate may be present in the composition in a concentration of from 7% to 29% by mass. Preferably, the alcohol ethoxylate is present in the composition in a concentration of from 12% to 22% by mass. Most preferably, the alcohol ethoxylate is present in the composition in a concentration of from 15% to 20% by mass, e.g. 17,26% by mass. The alcohol ethoxylate may have an HLB value in the range of 7.7 - 8.3.
Preferably, the alcohol ethoxylate is in the form of a mixture of 5 ethoxylates based on C9 and C„ alcohols. Even more preferably, the mixture of ethoxylates also includes ethoxylates of alcohols having chains of even numbers of carbon atoms. An example of a suitable alcohol ethoxylate mixture is Lutensol ON32 (Trademark), available in South Africa from BASF (Pty) Limited, 6 Carlisle Street, Paardeneiland, Cape Province.
) The diethanolamide may be present in the composition in a concentration of from 20% to 61 % by mass. Preferably, the diethanolamide is present in the composition in a concentration of from 30% to 51 % by mass. Most preferably, the diethanolamide is present in the composition in a concentration of from 34% to 44% by mass, e.g. 40,49% by mass.
5 The higher fatty acids mentioned above with reference to the diethanolamides include conventional emulsifier-forming acids. Examples of particularly suitable diethanolamides are lauric diethanolamide and oleic diethanolamide. Typically, equal portions of lauric and oleic diethanolamide are present in the composition.
The polyethylene glycol ester preferably has a molecular weight of at least 400. The polyethylene glycol ester may have an HLB value in the range of 11.2 - 1 1.6.
The polyethylene glycol ester may be present in the composition in a concentration of from 4.9% to 6.5% by mass. Preferably, the polyethylene glycol ester is present in the composition in a concentration of from 5,4% to 6,3% by mass. Most preferably, the polyethylene glycol ester is present in the composition in a concentration of from 5,6% to 6,0% by mass, e.g. 5,8% by mass.
The composition may include a surfactant when the sorbitan ester is not present or an additional surfactant to the sorbitan ester, when the sorbitan i ester is present. Thus, the composition may include ethylene glycol monobutyl ether or ethylene glycol monoethyl ether. The ethylene glycol monobutyl ether or ethylene glycol monoethyl ether, as the case may be, may be present in the composition in a concentration of from 1.1 % to 1 .7% by mass. Preferably, the ethylene glycol monobutyl ether or ethylene glycol monoethyl ether, as the case
» may be, is present in the composition in a concentration of from 1 ,3% to 1 ,6% by mass, and most preferably in a concentration of from 1 ,4% to 1 ,5% by mass, e.g. 1 ,45% by mass.
The invention extends to a solution of an oil and water, which includes a composition as hereinbefore described.
) The oil may be a fuel oil and the solution may include a fuel extender.
The fuel extender may be an alcohol, such as ethanol. The fuel extender may be present in the solution in a concentration of up to about 5% by mass.

The minimum quantity of composition to be added to a water and oil mixture comprising a few (e.g. 2 - 5) volumetric parts water per TOO volumetric parts oil is typically between about 5 and 15 volumetric parts composition per 100
5 volumetric parts of water and oil mixture. The addition of too low a quantity of composition to the oil and water is to be avoided as it may result in an emulsion being formed instead of a solution.
The volumetric ratio of the composition to the combined oil and water may be between 5:100 and 20:100 and the volumetric ratio of the water to the oil may be between 1 :100 and 10:100. Preferably, the volumetric ratio of the composition to the combined oil and water is between 12,7: 100 and 19,8:100 and the volumetric ratio of the water to the oil is between 1 ,7:100 and 8,6:100.
