The present invention relates to a composition comprising: (a) at least one botanical butter; (b) at least one alkaline agent comprising at least one primary amino group and at least three hydroxyl groups; (c) at least one wax; and (d) water. The composition according to the present invention does not produce NDELA, because it does not need to use TEA, but it can provide keratin fibers such as eyelashes with enhanced or improved cosmetic effects or properties, such as excellent volumizing effects (e.g., the thickness of keratin fibers is increased) and even application effects (e.g., the composition can be applied evenly onto keratin fibers to clean appearance of the keratin fibers).
