Abstract: A combination of a compact, economical, decorative, rigid, one-piece holder and a squeezable collapsible dispensing tube, where the holder has a supporting base with a planar bottom standing surface to which are attached two side walls such that their substantially planar inner surface face each other and form a substantially upright V-shaped notch. The dimension of the V-shaped notch, such as its height, its top opening width, and the width of the inner surfaces of the side walls, are such that a sufficient length of the bottom section of a full collapsible dispensing tube fits into and is firmly grasped by the V-shaped notch and is securely held in an upright position. These same dimensions should also be sufficient that a partially-emptied, collapsible dispensing tube, which has been flattened and folded a plurality of time--generally about four or five times for a toothpaste tube--fits into and is securely held upright by the notch of the holder.

Abstract: Novel substituted decahydroquinolines are prepared and used as ultraviolet (UV) light stabilizers for plastic materials subject to UV light degradation, particularly for polyolefins. Compositions containing the decahydroqinoline compounds exhibit excellent stability to UV light.
