关于此产品
将 C18 比例提高到 65.0–69.0%，使硬脂酸 1865 的熔程达到 58.0–63.0 °C，质地也比富含棕榈酸的三压级牌号更硬。其规格要求为白色珠状或片状，色度不超过 60 Hazen，碘值不高于 0.50 g I₂/100 g。酸值范围为 200.0–218.0 mg KOH/g，皂化值为 201.0–219.0 mg KOH/g。
较高的熔化特性适合棒状和块状产品以及在较高温度下运行的工艺。制皂以及个人护理膏霜和乳液是其成熟用途，此外还有塑料和橡胶加工以及金属硬脂酸盐生产。
另有一份有文件记载的 1865 规格以凝固点为依据，且酸值范围更窄，因此订购时请坚持采用一个完整方案，而不要混用限值。在任何交付之前，请确认每批随附的分析证书、SDS、25 kg 袋装或吨袋包装，以及本牌号在预期配方中的表现。
