Problems solved by technology

There are following defects in the transparent lipstick prepared with polyhydroxystearic acid and polyamide: use polyhydroxystearic acid as thickener, to make the product appearance clear and transparent, its consumption generally can not exceed 4.5%, otherwise the transparency of product will reduce, However, the transparent lipstick thickened at this dosage has a low melting point and insufficient hardness at room temperature, which makes it easy to break during application
Using polyamide as a thickener to prepare transparent lipstick, the thickening efficiency is relatively low, and it needs to be added in an amount of 20% to obtain the hardness required by the lipstick. However, the product that meets the hardness requirement is like a transparent plastic, with strong elasticity and toughness, but it is difficult to apply. poor moisture
