Disteardimonium Hectorite is a modified clay compound in which some sodium cations of the clay (hectorite) have been replaced by stearyldimonium groups (which include carbon chains containing 18 carbons).
Disteardimonium锂蒙脱石是一种改性的粘土化合物,其中粘土(锂蒙脱石)的某些钠阳离子已被硬脂基二铵基团取代(包括含18个碳的碳链)。
In cosmetics and personal care products, Disteardimonium Hectorite functions as a dispersing agent - nonsurfactant.
在化妆品和个人护理产品中,Disteardimonium锂蒙脱石用作分散剂-非表面活性剂。
Disteardimonium Hectorite is in a class of substances called quaternary ammonium compounds.
Ingredients in this class all have a nitrogen atom bound to four alkyl groups.
The nitrogen atom in these compounds always has a positive charge.
The alkyl groups in Disteardimonium Hectorite are two stearyl groups (18 carbons each) and two methyl groups (1 carbon each).
Disteardimonium鋰蒙脫石屬於一類稱為季銨化合物的物質。
這類成分均具有結合至四個烷基的氮原子。
這些化合物中的氮原子始終帶正電荷。
Disteardimonium鋰蒙脫石中的烷基是兩個硬脂基(每個18個碳)和兩個甲基(每個1個碳)。
The CIR Expert Panel reviewed the safety of Disteardimonium Hectorite with other quaternary ammonium hectorite compounds including dihydrogenated tallow benzylmonium hectorite, stearalkonium hectorite and quaternium-19 hectorite.
All of these compounds have high molecular weights and carry a positive charge; therefore, the CIR Expert Panel concluded that these compounds would not penetrate the skin.
At concentrations used in cosmetic products, Disteardimonium Hectorite and the related quaternary ammonium hectorite compounds were not dermal irritants or sensitizers.
CIR專家小組審查了Disteardimonium鋰蒙脫石與其他季銨鹽鋰蒙脫石化合物(包括二氫化牛脂芐基鋰蒙脫石,硬脂酸銨鋰蒙脫石和Quarternium-19鋰蒙脫石)的安全性。
所有這些化合物均具有高分子量並帶有正電荷; 因此,CIR專家小組得出結論,這些化合物不會滲透皮膚。
在化妝品中所用的濃度下,鋰硬脂酸二硬脂銨和相關的季銨鹽鋰蒙脫石化合物不是皮膚刺激劑或敏化劑。
