Problems solved by technology

Triethoxyoctylsilane-treated toner has extremely low surface tension and good hydrophobicity, and is easy to disperse in esters, mineral oil and silicone oil. Due to the viscosity of the product, it is not suitable for a large amount of application in ointment products; while the toner treated with polydimethylsiloxane has better powder texture and hiding power, but poor dispersion in other oils other than silicone oil system , has certain application limitations, and is more suitable for powder products; the toner treated with triisostearyl isopropyl titanium salt has the characteristics of low oil absorption value, which can greatly increase the toner consumption of the product formula, but this color The conformability of the powder is low, which cannot meet the requirements of consumers for the skin feel of the product

Abstract

The invention discloses lauroyl lysine treatment toner as well as a preparation method and application thereof. The preparation method comprises the following steps of (1) mixing lauroyl lysine and an oily medium at normal temperature to obtain turbid liquid, wherein the mass fraction of the lauroyl lysine in the turbid liquid is 5-20%; (2) adding inorganic toner into a stirring device, keeping the vacuum degree at 0-0.1 MPa, and spraying the turbid liquid at the stirring speed of 120-180rpm; (3) after the turbid liquid is sprayed, maintaining the vacuum degree at 0-0.1 MPa, increasing the stirring speed to 280-350 rpm, and continuing stirring; and (4) maintaining the vacuum degree and the stirring speed, heating to 100-150 DEG C to dry the toner, and cooling after drying to obtain the lauroyl lysine treatment toner. The prepared lauroyl lysine treatment toner has good adhesion and ductility on skin, the smoothness and fitness degree of a product can be improved when the lauroyl lysine treatment toner is applied, and in addition, due to the characteristics of lauroyl lysine, the moisture retention and skin affinity of the toner are improved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a lauroyl lysine-treated toner and a preparation method and application thereof. Background technique [0002] Toner, that is, coloring agent, is used in cosmetics to color the skin, hair and nails. With the help of the symmetry and coordination of colors, the outline of the body is clear and the skin color is even, showing the advantages of the appearance and making up for the partial defects of the appearance. , to achieve the purpose of beauty. With the increasing demand of consumers for high-end cosmetics, untreated toner can no longer meet consumers’ expectations for cosmetics. Due to the difference in functional groups, untreated toner has a certain affinity for oils. There may be color drift, color spots, color spots, fading, etc., or agglomeration, sedimentation, etc. after preliminary treatment into color paste. Therefore, surface treatment of toner is very necessary....
