Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
52 words
A composition consisting essentially of a compound of formula: ##STR2## in which R represents a hydrogen atom or an acetyl radical and R 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.
Claim 2
Dependent Claim
52 words
A composition consisting essentially of a compound of formula: ##STR2## in which R represents a hydrogen atom or an acetyl radical and R 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.
Claim 3
Dependent Claim
15 words
A composition according to claim 1, which contains less than 5% by volume of ethanol.
Claim 4
Dependent Claim
23 words
A composition according to claim 1, wherein, in the compound of formula (I), R represents hydrogen and R 1 represents a tert-butoxycarbonylamino radical.
Claim 5
Dependent Claim
25 words
A composition according to claim 1, wherein, in the compound of formula (I), R represents an acetyl group and R 1 represents a benzoyloxyamino radical.
Claim 6
Dependent Claim
17 words
A composition according to claim 1, which contains up to 200 mg/ml of compound of formula (I).
Claim 7
Dependent Claim
17 words
A composition according to claim 3, which contains 20 to 80 mg/ml of compound of formula (I).
Claim 8
Dependent Claim
17 words
A composition according to claim 4, which contains 6 to 20 mg/ml of compound of formula (I).
Claim 9
Dependent Claim
15 words
A composition according to claim 2, wherein the composition contains less than 2% of ethanol.
Claim 10
Dependent Claim
17 words
A composition according to claim 5, which contains up to 80 mg/ml of compound of formula (I).
Claim 11
Dependent Claim
57 words
Composition consisting essentially of a taxane derivative of the formula: ##STR3## in which R represents a hydrogen atom or an acetyl radical and R 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.
Claim 12
Dependent Claim
57 words
Composition consisting essentially of a taxane derivative of the formula: ##STR3## in which R represents a hydrogen atom or an acetyl radical and R 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.
Claim 13
Dependent Claim
13 words
Composition according to claim 10, wherein ethanol is less than 2% by volume.
Claim 14
Dependent Claim
28 words

Claim 17
Dependent Claim
27 words
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.
Claim 18
Dependent Claim
33 words
