Abstract: A nitrocellulose-based composition for use as a propellant or as a combustible item is provided. The nitrocellulose-based composition includes a nitrate ester-based component including nitrocellulose; and a stabiliser (I) in the form of a long aliphatic chain having at least two unsaturation sites, the compound having a molecular weight of at least (120) and an iodine number of at least (25).

Abstract: The present disclosure is directed to a nitrocellulose-based propellant composition comprising: (a) a nitrate ester-based propellant comprising nitrocellulose; and (b) a stabiliser comprising a non-aromatic compound (12) consisting of a general ionone formula (12-I), (12-II), (12-III) or (12-IV): wherein R1 represents a ketone, hydroxyl, carboxyl, aldehyde or an unsaturated alkyl group, preferably —C(O)CH3 (corresponding to alpha, beta, gamma and pseudo ionone).

Abstract: The present disclosure is directed to a nitrocellulose-based propellant composition comprising: (a) a nitrate ester based propellant comprising nitrocellulose; and (b) a stabilizer consisting of a tocopherol compound with a general formula (I), wherein: X is oxygen; R1 is selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, heteroaryl, carboxylic acid, carboxylate, ester, saccharide, alkoxy-linked saccharide, alcohol, and ethers; R2 is selected from the group consisting of hydrogen methyl, benzyl carboxylic acid, benzyl carboxylate, benzylester and saccharide; R3 is selected from the group consisting of hydrogen, methyl, benzyl carboxylic acid, benzyl carboxylate, benzylester and saccharide; R4 is selected from the group consisting of methyl, benzyl carboxylic acid, benzyl carboxylate, benzylester and saccharide; and R5 is selected from the group consisting of alkyl and alkenyl.

Abstract: The present invention concerns a nitrocellulose-based propellant composition comprising: (a) a nitrate ester based propellant consisting of nitrocellulose alone (single base) or in combination at least with a blasting oil (double or higher base); and (b) a stabilizer consisting of a general formula (I): Wherein the stabilizer combines efficient, long term stability of the nitrocellulose-based propellants composition without formation of any detectable amounts of carcinogenic or mutagenic by-products, such as —NNO groups.
