8. The diaper according to claim 1 wherein the outer layer is waterproof.

9. The diaper according to claim 1 wherein the outer layer is configured to receive an insertion of the absorbent core.

10. The diaper according to claim 1 wherein the outer layer is made from a material comprising a material selected from the group consisting of:

polyethylene, nonwoven film, composite film, cloth, and any combination thereof.

I I . The diaper according to claim 1 wherein the diaper is disposable.

12. The diaper according to claim 1 wherein the outer layer is reusable.

13. A bandage comprising :

an absorbent layer comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of: sulfur, phosphorus, boron, and chlorine; wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate; and

a strip designed to maintain the absorbent layer in contact with a wound. 14. The bandage of claim 13 wherein the nonmetal is present in no more than about 25% by weight of the substituted cellulose acetate.

15. The bandage according to claim 13 wherein the absorbent layer further comprises a medicant.

16. The bandage of claim 15 wherein the medicant comprises an active ingredient selected from the group consisting of: an antibiotic, an analgesic, an antipyretic, an antimicrobial, an antiseptic, an antiallergy, an anti-acne, an anesthetic, an anti-inflammatory, a hemostat, a cosmetic, a vitamin, a

vasodilator, an emollient, a pH regulator, an antipruritic, a counterirritant, an antihistamine, a steroid, and any combination thereof.

17. The bandage according to claim 13 wherein the wound is selected from the group consisting of: an incision, a laceration, an abrasion, a puncture wound, a penetration wound, and any combinations of these.

18. The bandage according to claim 13 wherein the strip is elastic.

19. The bandage according to claim 13 wherein the strip comprises a material selected from the group consisting of: woven fabric, plastic, latex, and any combination thereof.

20. The bandage according to claim 13 wherein the strip is adhesive.

21. A potting soil composition comprising :

an organic compost; and

an absorbent composition comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of: sulfur, phosphorus, boron, and chlorine; wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.

22. The potting soil composition of claim 21 wherein the nonmetal is present in no more than about 25% by weight of the substituted cellulose acetate.

23. The potting soil composition of claim 21 further comprising at least one component selected from the group consisting of: loam, diatomaceous earth component, Perlite component, and any combination thereof.

24. The potting soil composition of claim 21 wherein the loam comprises a component selected from the group consisting of: sand, silt, clay, and any combination thereof.

25. The potting soil composition of claim 21 wherein the diatomaceous earth component comprises a component selected from the group consisting of:

diatomaceous earth, phosphate, magnesium, potassium, nitrogen, and any combination thereof.

26. An amended soil composition comprising :

a soil composition; and

a water retention additive comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of: sulfur, phosphorus, boron, and chlorine; wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
