新型环保蜡笔的制备

Preparation of a Novel Environmental Crayon

以可食用植物基脂肪酸甘油酯和氢化植物油代替传统石蜡做基材,以可食用的聚甘油酯代替传统铅盐助剂做分散剂,以天然可食用色素代替矿物颜料和有机合成颜料做颜色来源,辅加各种环保填料得到环保型蜡笔。此环保蜡笔原料均来自天然材料,对人体无害,值得推广。

The environmental cryayons with edible plant - based fatty acid glycerides and hydrogenated vegetable oils instead of paraftln waxes as the substrate, edible polyglyceryl esters instead of leadsah additives as the dispersant, natural edible pigments instead of mineral pigments and organic synthetic pigments as the color source, combining with a variety of environmentally friendly fillers, were prepared. The materials of the environmental crayons are all from nature, no harming to human beings, so it＇s worthy to promote those crayons widely.
