关于此产品
硬脂酸 1890 接近于单一碳链物料：C18 占其 88.0–94.0%，而不像混合牌号那样与棕榈酸共同构成。因此其熔程较窄，为 65.0–68.0 °C。酸值在 196.0–202.0 mg KOH/g 范围内，皂化值在 197.0–203.0 mg KOH/g 范围内；碘值不得超过 0.50 g I₂/100 g，Hazen 色度不得超过 60。
在纯度决定性能的场合，本牌号用于医药和个人护理配方、乳化剂和酯类生产、高纯度金属硬脂酸盐以及要求低色度和低气味的产品。肥皂、乳化剂和润滑剂制造是其有文件记载的商业市场。
每份订单都应注明所需的形态、包装和文件；规格书给出的包装为 25 kg 袋和吨袋。支持特定最终用途的文件需逐单商定，因此请将其与安全资料和批次分析记录一并索取。用于医药或个人护理时，请确认本牌号满足该用途的要求，并先在您自己的配方中进行验证。
