Natural polymers (≈45 % of market) encompass cellulose‑derived derivatives (e.g., methylcellulose, hydroxypropyl cellulose), starch‑based gums, and protein‑based agents such as gelatin; they are preferred where biodegradability and clean‑label claims are paramount. Within this family, the hydrogel subtype, typically supplied as aqueous dispersions, dominates food and cosmetic applications due to its rapid swelling kinetics, while the granular subtype, often used in agriculture, provides controlled release of moisture. Synthetic polymers (≈55 %) include polyacrylamide, polyvinyl alcohol, and sulfonated polymers, distinguished by higher absorption capacity and resistance to microbial degradation. Sub‑categories comprise liquid formulations, favored in pharmaceutical coating processes, and powder grades, essential for high‑load absorbent cores in personal‑care products. The relative weight of each type directly influences total market valuation, as price differentials, performance metrics, and regulatory acceptance vary across the natural versus synthetic spectrum, shaping the overall market taxonomy.
