Abstract
The present invention relates to bar compositions comprising a mixture of higher melting point and lower molecular weight (100 to about 1400) lower melting point polyalkylene glycol(s) in which use of the lower molecular weight polyalkylene glycol or glycols allows enhanced rates of extrusion from the plodder.
