Abstract
The present invention relates to a process for producing menthol particles stabilized against caking, wherein menthol particles are, following shaping, stored for at least 7 days at a temperature of 0 to 30° C., after which the menthol particles are supplied with a minimum input of mechanical energy. The present invention further relates to storage-stable menthol particles and to the use of said menthol particles in household and consumer goods of all kinds.
Claims13
A process for producing menthol particles stabilized against caking, said process comprising storing menthol particles, following shaping, for at least 7 days at a temperature of 0 to 30° C., after which the menthol particles are supplied with at least as much mechanical energy as they receive when
- 20 kg of said menthol particles
- are packed into a bag made from polyethylene film 0.12 mm thick having the dimensions length L (bag) 660 mm and width W (bag) 690 mm, sealing the bag;
- said bag is packed into a cuboidal box made from double-walled corrugated cardboard having the internal dimensions length L (box) 385 mm, width W (box) 320 mm, and height H (box) 450 mm and a corrugated cardboard thickness of 6 mm, and
- said box is dropped once from a height of 1.0 m onto an inelastic surface plane-parallel to the side formed by L (box) and H (box).
