 size of the potassium carbonate can be varied virtually unlimitedly within this range. When use is made of more finely divided potassium carbonate, a better stabilizing action is usually achieved, but handling of the product is hampered due to the increased amount of dust formed in the case of very finely divided material, so that in some circumstances it will be necessary to determine the best particle size of the potassium carbonate for use in a particular application. Generally the average particle size (equal to 50 wt % retention of the potassium carbonate on a sieve of the specified mesh size) is from 0.005 to 1.0 mm, usually from 0.02 to 0.5 mm.
The compositions of the invention can be stored for longer periods of time or at higher temperatures (for example in dye shops in tropical countries) than is the case with known compositions or show, when stored for comparatively long periods, less generation of objectionable odors, less reduction in the content of sulfinic derivative(s) and/or less inclination to self-ignition. Similarly, the composition of the invention is less sticky than the commercial compositions. For example, it can be readily metered by means of screw conveyors without sticking to the walls thereof. Furthermore the compositions of the invention do not cause turbidity or precipitation in most fields of application. Contoured cushioning is commonly used for many different types of seats and mattresses. For example, contoured cushioning is sometimes used in seats, such as office chairs, wheelchairs, and vehicle seats to provide lumbar support and a comfortable seat base. Typically, contoured cushioning is provided by locating padding at specific parts of the seat base or backrest to create areas of greater or lesser cushioning and contouring. Contoured cushioning is sometimes used in seats, such as wheelchairs, to aid the comfort of the user and to help those with significant physical disabilities to sit comfortably and safely in a wheelchair. People with Cerebral Palsy, neuromuscular diseases, brain injuries, spinal injuries and many other medical conditions often need significant and customised contouring of seats to properly support their posture and positioning. The contouring required can be very user specific, with some people requiring different areas of the seat to be raised or lowered and to different extents. The required extent of contouring and the position of contoured areas of the seat may need to be regularly modified for some users. Unfortunately, many known seating systems do not provide contoured seating in which the extent and location of the contouring can be readily
size of the potassium carbonate can be varied virtually unlimitedly within this range. When use is made of more finely separate potassium carbonate, a dependable stabilizing action is usually achieve, but handling of the product is hampered due to the increase amount of dust form in the case of very finely divided fabric, so that in some circumstances it will be necessary to determine the best particle size of the potassium carbonate for habit in a particular application. Generally the average particle size (adequate to 50 wt% retention of the potassium carbonate on a sieve of the specified mesh size) is from 0.005 to 1.0 millimeter, usually from 0.02 to 0.5 mm.

Similarly, the composition of the invention is less sticky than the commercial compositions. For example, it can be promptly meter by means of fuck conveyer without sticking to the walls thereof. Furthermore the typography of the invention do not cause turbidity or precipitation in most fields of application. Contoured padding is commonly used for many different types of seats and mattresses. For example, contoured cushioning is sometimes used in seats, such as office professorship, wheelchair, and fomite seat to provide lumbar support and a comfortable seat root. Typically, contoured cushioning is provided by locate padding at specific parts of the seat base or backrest to produce areas of big or lesser cushioning and contouring. Contoured padding is sometimes used in seats, such as wheelchairs, to aid the consolation of the user and to avail those with significant physical disability to sit comfortably and safely in a wheelchair. People with Cerebral Palsy, neuromuscular diseases, brain injuries, spinal injuries and many other medical conditions often need meaning and customised contouring of seats to properly corroborate their posture and positioning. The contouring required can be very user specific, with some people requiring different area of the seat to be raised or lowered and to different extents. The required extent of contouring and the position of contoured area of the buttocks may want to be regularly modified for some users. Unfortunately, many known seating systems do not provide contoured seating in which the extent and placement of the contouring can be readily
