Abstract
Synthetic monofilaments or bristles made from a thermoplastic elastomeric composition containing an aluminum silicate. The synthetic monofilaments or bristles possess properties, such as stiffness, similar to those of natural bristles such as goat hair, but without the unwanted side effects of natural bristles or prior synthetic bristles. A method for making such synthetic monofilaments or bristles of various lengths and diameters having a desirable wavy appearance is achieved by post-conditioning or mechanically crimping the monofilaments. The synthetic monofilaments or bristles are capable of being formed into brushes of all types and for all uses, especially as cosmetic brushes.
