Lab three roll mill for lipstick

Lipsticks and lip balms have higher percentages of fine and coarse particles, because some particles may be repeatedly dispersed due to dispersing forces, while others are not dispersed at all. The three roll mill is the most effective. For each three roll mill, the reduction of particle size and the dispersion of agglomerates are accomplished by the combined action of the rolling pressure between the rollers and the high shear force caused by different roller speeds. Since the entire material is filled into the roller gap, the particle size is precisely controlled and narrowly distributed. Through the adjustment of the roller spacing, the particle size can be easily and accurately processed to the micron level. Therefore, compared with other grinding equipment, the three roll mill can effectively improve the particle size distribution and make the particle size distribution more concentrated. Application of three roll mill in lipstick production The production of the lipstick is divided into four main stages, the first and second stages will use a three roll mill. The basic raw materials for making lipsticks include waxes, oils, and pigments/pigments. A typical raw material ratio is 20/30% wax, 50/70% grease, and 5/15% pigment. In the first stage, the pigment needs to be mixed with an appropriate amount of oil (the ideal ratio of pigment to oil is two parts oil and one part pigment), and then the mixture is ground with a three roll mill to uniformly disperse the pigment polymer. In the second stage, the uniformly dispersed pigment and grease mixture is added to the dissolved wax and remaining oil (or a small amount of aromatherapy can be added) and then reprocessed with a three roll mill to obtain the desired particle size (usually 20 microns) ). A three-roll mixture of uniformly dispersed pigment and oil is added to the dissolved wax and remaining oil (alternatively, a small amount of aromatics can be added) and reprocessed through a three roll mill to obtain the desired particle size (usually 20 microns). Problems with using a three roll mill lipstick 1. Pigment grinding, since pigments are mostly powder, although the particles are relatively fine, they are often aggregated into lumps, and it is difficult to disperse them evenly when they are directly added to the oil matrix. Therefore, the pigments used must be ground beforehand. In order to make the grinding smooth, it is often necessary to add a small amount of liquid oil to the pigment and mix it, and then use mechanical grinding. 2. The colorant is mixed with the oil base. Generally, the dye is added to the solvent and heated and melted, and then the ground pigment and wax raw materials are added. After melting, the semi-solid oil is added, stirred evenly, and ground while hot; degassing Then add spices and other accessories.
