Polysiloxane, method for its production and deodorant comprising it

An aminooxyalkyl-containing polysiloxane having a structural unit of formula (1):

• where each R is independently a C1-4 alkyl group, a C1-4 alkoxy group or a hydroxy group,
• each Q is independently selected from the group consisting of —CH2—, —CH2CH2— and —CH2—Ra—CH2— wherein Ra is a C1-18 alkylene group in which two or more interspaced —CH2— groups may each be independently replaced by —O—, —(C═O)O—, —O(C—O)—, —O(C—O)—O—, —C(═O)—NH—, —NH—(C—O)—, —CH—CH— or —C≡C—, and in which a hydrogen atom in the alkylene group may be substituted with a C1-3 alkyl group, and
• M is an aluminum atom, a silicon atom or a titanium atom, and n is an integer of 1 or 2, provided that when M is an aluminum atom, n is 1, and when M is a silicon atom or a titanium atom, n is 2.
