Abstract

The invention discloses a method for preparing a natural pigment-cladded microcapsule lipstick. The method comprises the following steps: firstly, weighing astaxanthin, dragon fruit pericarp haematochrome and cochineal haematochrome; slowly adding to base oil, and stirring; adding tween-80, mixing evenly and homogenizing at a high speed, so as to prepare a mixed solution; adding the homogenized mixed solution to a chitosan mixed solution, and mixing evenly; adding the evenly mixed solution to an arabic gum solution; carrying out complex coacervation at 60-70 DEG C for 10-15 minutes; and finally standing a reaction solution, centrifuging and washing, and drying in a freezer dryer, so as to prepare the natural pigment-cladded microcapsule lipstick. The method disclosed by the invention has a good emulsification effect; the prepared microcapsule product is relatively uniform in quality; and the activity of the natural pigment is not destroyed.

Description

technical field [0001] The invention belongs to the field of microcapsules, and in particular relates to a preparation method of a microcapsule lipstick wrapped with natural pigments. [0002] Background technique [0003] The lip tissue layer is only half the thickness of the trunk skin, and there are no sweat glands and sebaceous glands. It is the weakest and most vulnerable part of the facial features against environmental intrusion. It is easily affected by negative factors, causing mucosal damage, and inducing Cheilitis. In order to maintain the lips, lipstick has gradually become a must-have consumer product for the public to care for the extremely vulnerable lips. However, with the gradual improvement of people's living standards, people's requirements for lipsticks are not only the original moisturizing effect, but also new requirements such as beautifying lip color, pure natural non-toxic, and biological health care effects. In view of this, it is urgent to devel...
