Delivering perfume to a fabric when washing the laundry is not easy because, they are volatile substances and are easily rinsed during washing cycle. A further difficulty arises from the widespread use of clothes dryers in which washed fabrics are tumbled at relatively high temperatures. Even perfumes with a degree of substantivity for fabrics will volatilize to a large extent in a dryer with the result that the finished laundry only has a very faint odor which rapidly dissipates. Yet by encapsulating the perfume in a water-insoluble shell, the perfume is protected throughout the laundry operation.
A significant number of microcapsules are entrained in or otherwise become associated with the fabric during the washing process and remain intact through the remainder of the laundry procedure. The perfume is actually released mainly when the microcapsules rupture. This can occur to some extent during the drying step and ironing but mainly it occurs when clothes are being used.
Mikrocaps offers an encapsulation service to fragrance companies and can provide different types of capsules such as biodegradable (BIOCAPS), formaldehyde-free and melamine capsules.
Many cosmetics and personal care products contain active substances that require encapsulation for increased stability. Microencapsulation provides an important tool for cosmetic industry, enabling protection and controlled release of several active agents, like fragrances, essential and natural oils, antioxidants, vitamins, etc. In addition to formaldehyde-free capsules, MIkroCAps also offers biodegradable capsules (BIOCAPS) and in this way enables partners to deliver in line with directives on the elimination of microplastics.
