Biodegradable compositions and articles made from cellulose acetate

A composition comprising:

• (1) a cellulose acetate,
• wherein the cellulose acetate has an acetyl degree of substitution (“DSAc”) in the range of from 2.2 to 2.6, and wherein the number average molecular weight (“Mn”) of the cellulose acetate is between 20,000 and 100,000, wherein the Mn is measured using gel permeation chromatography with a polystyrene equivalent and using N-methyl-2-pyrrolidone (NMP) as the solvent,
• (2) from 17-23 wt % of a polyethylene glycol 400 (“PEG400”), and
• (3) a stabilizer, which comprises a combination of (i) a secondary antioxidant which is a phosphite compound;
• and (ii) one or more primary antioxidants, (iii) citric acid, or a combination thereof,
• wherein the secondary antioxidant is present at from 0.01 to 0.8 wt %,
• wherein the primary antioxidant is present at from 0.05 to 0.7 wt %,
• wherein the citric acid is present at from 0.05 to 0.2 wt %,
• all weight percentage is based on the total weight of the composition,
• wherein the composition is melt processable, biodegradable, and disintegrable.
