Abstract
Description
Technical Field
[0001] This invention relates to the field of cosmetics, and more particularly to a stable liquid crystal emulsion and its preparation method. Background Technology
[0002] With the rapid development of the cosmetics market and the widespread use of the internet, consumers have gained a deeper understanding of cosmetics, and their focus has shifted to the quality of the products themselves. Therefore, cosmetic companies need to gradually shift their focus to technological innovation in cosmetics. Layered liquid crystals, due to their unique oil / liquid / water structure highly similar to the oil / stratum corneum / water structure of human skin, exhibit high skin affinity, improving product stability, enhancing emulsion water retention, and slowing the release of active ingredients, thus contributing to the efficacy of cosmetics and attracting widespread attention in the cosmetics industry. Liquid crystal emulsions form an ordered multilayer structure—the liquid crystal structure—through the alternating arrangement of emulsifier molecules with amphiphilic structures at the oil / water interface. To date, researchers have conducted extensive studies on the factors influencing the formation of liquid crystal structures, but there is very little research on the impact of formulation composition on the stability of liquid crystal structures. The liquid crystal structure of liquid crystal emulsions gradually fades or even disappears completely during storage, thus significantly limiting their widespread application.
[0003] There are various liquid crystal emulsion formulations in the existing technology, but research has found that most of the liquid crystal emulsions prepared by the existing technical solutions have poor stability. After being placed under accelerated conditions (40℃, 75%RH) and low temperature conditions (-8℃) for a period of time, the amount of liquid crystal is significantly reduced.
[0004] Therefore, there is still an urgent need for a liquid crystal emulsion with good stability. Summary of the Invention
