DEFINITION

Classification: 106/144.1

Dextrin or derivative, carbohydrate gum or derivative (e.g., arabic, tragacanth, guar, karaya, agar agar, algin, irish moss, etc.):

(under subclass 135.1) Compositions wherein the carbohydrate is dextrin, carbohydrate gum, or derivative thereof.

(1) Note. Dextrin consists of various gummy polysaccharides produced by thermal or acid degradation of starch.

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

(4) Note. Examples of derivatives included herein are esterified, etherified, sulfonated, and borated.

(5) Note. The term "derivative" in this and indented subclasses is intended to include a chemical modification of the carbohydrate gum or dextrin wherein the carbon skeleton of the carbohydrate gum or dextrin is not destroyed or wherein the carbon skeleton of the carbohydrate gum or dextrin is indeterminate.
