Segmentation by type further refines the market taxonomy, distinguishing white oil into mineral‑based, synthetic ester‑based, and hydrogenated polybutene sub‑categories. Mineral‑based white oil, derived from highly refined petroleum distillates, dominates the market (about 60%) due to its cost‑effectiveness and established supply chains, especially in bulk food‑processing operations where purity specifications are met through rigorous de‑odorization. Synthetic ester‑based white oil captures roughly 30% of demand, favored in pharmaceutical contexts for its superior oxidative stability, lower toxicity, and customizable fatty‑acid profiles that support stringent USP‑NF standards. Hydrogenated polybutene, a niche segment representing near 10% of the market, offers ultra‑low volatility and high thermal resistance, making it suitable for specialized pharmaceutical formulations and high‑temperature food‑processing equipment. The relative weight of each type aligns with the performance and compliance requirements of the corresponding application segments, thereby influencing overall market dynamics.
