DEFINITION

Classification: 106/126.3

Carbohydrate gum or cellulosic material:

(under subclass 126.1) Compositions wherein the carbohydrate is a carbohydrate gum or a chemically modified carbohydrate gum, cellulose or a chemically modified cellulose, or a naturally occurring material which has cellulose as one of its ingredients.

(1) Note. Carbohydrate gums include but are not limited to arabic, tragacanth, xanthan, galactomannan, irish moss, carrageenan, karaya, agar agar, algin, guar, xylogalactan, and glucomannan.

(2) Note. Carbohydrate gums are highly branched polysaccharides composed of two or more monosaccharides, and are exudations of plants produced by the plant to cover wounds and to prevent attack by organisms.

(3) Note. The term "derivative" herein is intended to include a chemical modification of the carbohydrate gum or cellulose wherein the carbon skeleton of the carbohydrate gum or cellulose is not destroyed or wherein the carbon skeleton of the carbohydrate gum or cellulose is indeterminate.

(4) Note. This subclass and indented subclasses provide for relatively pure cellulose (e.g., cotton linters, etc.), regenerated cellulose (e.g., cellophane and rayon), or chemically modified forms of cellulose (e.g., pyroxylin, viscose, etc.) for which there is no provision elsewhere.
