Abstract
An aqueous antiperspirant/deodorant composition comprising: (a) at least one active chosen from an antiperspirant active and a deodorant active, (b) a mixture comprising at least one basic compound chosen from a basic amide and a basic amine and a counterpart material for the basic amide and/or basic amine, and (c) at least 10 weight % water. Also, a method of manufacturing the composition.

An aqueous antiperspirant composition comprising:
- a. an antiperspirant active,
- b. a mixture comprising at least one basic compound chosen from a basic amide and a basic amine and a counterpart material for the basic amide and/or basic amine, and
- c. at least 10 weight % water,
- wherein the antiperspirant active, the at least one basic compound chosen from a basic amide and a basic amine, and the counterpart material are present such that a selection of a type of each and an amount of each is such that an osmolyte system and/or ionic liquid is formed.

A method of producing an aqueous antiperspirant composition, the method comprising the steps of:
- a. providing an antiperspirant active, a mixture comprising at least one basic compound chosen from a basic amide and a basic amine and a counterpart material for the basic amide and/or basic amine, and at least 10 weight % water, wherein the antiperspirant active, the at least one basic compound chosen from a basic amide and a basic amine, and the counterpart material are present such that a selection of a type of each and an amount of each is such that an osmolyte system and/or ionic liquid can be formed;
- and
- b. heating the composition to form a stabilized system in a form of the osmolyte system and/or ionic liquid.
