DEFINITION

Classification: 507/110

Organic component is carbohydrate or derivative thereof (e.g., sugar or gum, such as galactomannan, xanthan, etc.) or carboxylic acid ester of an alcohol which has five or more hydroxy groups bonded directly to carbons:

(under subclass 103) Composition comprising a compound containing an organic component which is a carbohydrate or derivative thereof or a carboxylic acid ester of an alcohol which has five or more hydroxy groups bonded directly to

carbons (e.g., sorbitan alkylate, etc.).

(1) Note. Carbohydrate denotes a compound with the empirical formula Cx(H2O)y, wherein x is 5 or more and y is 5 or more, or derivative thereof (e.g., isolated gums, (poly)saccharides, sugars, etc.).

(2) Note. Included in this subclass is a carbohydrate or derivative which is grafted onto a polymer or resin.
