Problems solved by technology

In addition, the product needs to be stored at high or low temperature for a long time in different sales areas, which is prone to adverse phenomena such as hardening of the pigment of the finished liquid pen tip to block the tip of the pen, and obvious layering of the color in the tip of the pen resulting in uneven color.

Embodiment

[0036] Take a clean 250ml beaker and add 90ml of deionized water, then weigh 5g of magnesium aluminum silicate solid with a balance, and add the magnesium aluminum silicate solid to the beaker under constant stirring with a glass rod until the solid is completely wetted. Add 5ml of aminoacrylic acid (ester) copolymer to the beaker with a plastic dropper, and finally use a high-speed homogeneous mixer to stir at a speed of 10,000rpm. After 10 minutes of homogenization time, a non-transparent white 5% magnesium aluminum silicate can be obtained. - Aminoacrylic acid (ester) copolymer water dispersant sol.

[0037] A liquid pen comprising the above-mentioned dispersant, comprising the following components in mass percent: polyol 10%; preservative 1%; deionized water 30%; dispersant 10%; water-based pigment 29%; film-forming agent 20%. Pre-mix polyols, preservatives, deionized water, dispersants, and water-based pigments in a beaker under stirring with a glass rod, and then grind t...

Abstract

The invention discloses a cosmetic grade water-based pigment composite dispersant and a production method thereof and a liquid pen using the composite dispersant. The cosmetic grade water-based pigment composite dispersant is prepared from magnesium aluminum silicate, deionized water and an amino acrylic acid (ester) copolymers. The cosmetic grade water-based pigment composite dispersant is non-toxic and non-irritating, has good economic benefits, can be used as an excellent suspending agent, can improve the effectiveness of the amino acrylic acid (ester) copolymers, can be used as a modifierand thickener for viscosity to obtain an excellent suspension effect in a lower viscosity range, and has a wide range of PH range stability.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a cosmetic-grade water-based pigment composite dispersant, a production method thereof, and a liquid pen using the composite dispersant. Background technique [0002] At present, most of the color liquid pen formulas on the market are still based on water-based pigments and transparent iron oxide color paste components. Although the product performance is relatively stable, the product’s color thickness and color hiding power are not as good as toner system formulas , and the current market demand for toner system brown liquid pens is increasing. [0003] However, in the formula of the toner system, the pigment accounts for 25-30%, and the effect of the suspending agent and the dispersing agent in the formula is highly required. After the liquid semi-finished product is made and stored, the pigment must not settle or be stirred into a solid-liquid two-phase can still return to...
