Linum Usitatissimum (Linseed) Seed Extract

Incompatibilities and failure points

对电解质高度敏感是它最大的限制:高浓度氯化钠、镁盐、盐形式的活性物,以及含盐量高的海藻或发酵提取物,会让黏液脱水收缩,表现为黏度骤降、絮凝甚至分层,和高盐组分同锅必须先小试。阴离子性质使它与阳离子聚合物、阳离子表活(季铵盐类调理剂)复配时产生絮状沉淀。乙醇浓度偏高会直接析出。钙、镁、铝、锌等多价金属离子可能与其交联成粒。与卡波体系叠加时黏度和触感变化不可预测,通常建议二选一,若必须共用则重新配平中和剂用量并做长期观察。

Stability

水提黏液耐热性一般,80 ℃ 以上长时间加热会降解并失去特征成膜感,应作为低温后加原料。见光遇氧容易变色(浅黄转黄褐)并可能出现哈味,与来料中残留亚麻籽油脂的氧化有关,建议避光包装、控制来料油脂残留、必要时配合抗氧化与螯合体系。天然营养丰富,微生物风险高,来料菌检与成品防腐挑战都要做足,稀释后的中间体不可存放。pH 明显偏离中性时黏度下降。冻融后可能析水,冬储前要做低温循环考察。

Processing notes

做后加:乳化或增稠完成、体系降到 40 ℃ 以下再加入,先用部分水或甘油稀释后细流并入,直接倒进高黏体系会形成局部胶团且搅不散。投料前把配方里所有含盐组分点一遍,把它和高盐活性物分开阶段加入,并在盐加完之后再补加,同时观察黏度变化,这一步能避免大部分放大失败。若使用粉状亚麻胶,预分散方式与罗望子胶相同,先与多元醇打浆。水合完成后不要再高速均质,剪切会破坏黏液特有的拉丝感。批次间黏度与颜色差异较大,加料速度过快会造成局部过浓结块,建议用计量泵细流加入并全程中速搅拌。

What it addresses

亚麻籽外层水提得到的酸性黏液多糖(以阿拉伯木聚糖、鼠李半乳糖醛酸聚糖为主),在水中形成滑腻的黏液体系,干燥后留下柔软连续的膜,给配方带来水润拉丝的即时肤感和轻微的紧绷收敛感。常用于免洗精华、啫喱与洗护中的天然成膜方向。
