Application Number:	07/930,392
Patent Claims:	1. A composition consisting essentially of a compound of formula: ##STR2## in which R represents a hydrogen atom or an acetyl radical and R.sub.1 represents a tert-butoxycarbonylamino or benzoylamino radical, dissolved in a surfactant selected from the group consisting of polysorbate, polyoxyethylene glycol and hydrogenated castor oil, and essentially free of ethanol. 2. A composition according to claim 1, which contains less than 5% by volume of ethanol. 3. A composition according to claim 1, wherein, in the compound of formula (I), R represents hydrogen and R.sub.1 represents a tert-butoxycarbonylamino radical. 4. A composition according to claim 1, wherein, in the compound of formula (I), R represents an acetyl group and R.sub.1 represents a benzoyloxyamino radical. 5. A composition according to claim 1, which contains up to 200 mg/ml of compound of formula (I). 6. A composition according to claim 3, which contains 20 to 80 mg/ml of compound of formula (I). 7. A composition according to claim 4, which contains 6 to 20 mg/ml of compound of formula (I). 8. A composition according to claim 2, wherein the composition contains less than 2% of ethanol. 9. A composition according to claim 5, which contains up to 80 mg/ml of compound of formula (I). 10. Composition consisting essentially of a taxane derivative of the formula: ##STR3## in which R represents a hydrogen atom or an acetyl radical and R.sub.1 represents a tert-butoxycarbonylamino or benzoylamino radical dissolved in a surfactant selected from the group consisting of polysorbate, polyoxyethylene glycol and hydrogenated castor oil, said composition containing less than 5% by volume ethanol. 11. Composition according to claim 10, wherein ethanol is less than 2% by volume. 12. A perfusion comprising less than 0.5 mg/ml of compound as defined in claim 3 and less than 1 ml/l of ethanol and less than 15 ml/l of surfactant. 13. A perfusion, comprising 1 mg/ml or less of compound as defined in claim 4 and less than 1 ml/l of ethanol. 14. A perfusion according to claim 12, wherein the perfusion contains 0.1 to 0.3 mg/ml of a compound of formula (I) wherein R represents hydrogen and R.sub.1 represents a tert-butoxycarbonylamino radical. 15. A method for preparing a composition according to claim 1, which comprises dissolving a compound of formula (I) in ethanol, adding the surfactant and removing the ethanol. 16. A method for preparing a composition according to claim 1, which comprises slowly adding a compound of formula (I) to a solution of the surfactant containing 1 to 2% by volume of ethanol. 17. A method for preparing a composition according to claim 15, wherein ethanol is removed by evaporation.
