Abstract
Perfuming or flavoring microcapsules that include, further to a perfuming or flavoring ingredient and a carrier material, an explosion suppressant, proved to undergo, when suspended in hot air during their preparation, an explosion of a reduced violence. The explosion suppressant is selected from C1 to C12 carboxylic acids, their salts and mixtures of these.
Claims14
A perfuming or flavoring microcapsule comprising at least one perfuming or flavoring ingredient dispersed in or adsorbed within a carrier material, and an effective amount of a explosion suppressant selected from the group of C1-C12 carboxylic acids, salts of C1-C12 carboxylic acids, and mixtures thereof.
A method for reducing violence of explosion of a powdered composition, which comprises
- adding to the powdered composition a fireproof agent selected from the group consisting of C1-C12 carboxylic acids, salts of C1-C12 carboxylic acids, and mixtures thereof to the powdered composition, or
- incorporating the fire proof agent in and/or within particles of the powdered composition, or,
- coating the fire proof agent onto the powdered composition.
