Embodiment

[0038] The preparation method of embodiment is as follows:

[0039] Weigh ceramide, hydrogenated lecithin, butanediol, heat to 75°C, and conventionally stir until a uniform solution is used as solution A; weigh PEG40 hydrogenated castor oil, glycerin, hexanediol, p-hydroxyacetophenone, vitamin E, Purified water, heated to 70°C, and conventionally stirred until a uniform solution was used as solution B; solution B was dispersed at 70°C with an IKA disperser at 6000 rpm and added to solution A, and then dispersed for 10 minutes and cooled naturally (at this time, it was not Microjet treated sample); the cooled mixed solution was homogenized 3 times with nano microjet 30000psi to obtain the final solution, ceramide E emulsifier, 200g in total.

[0040] Routine Test Example Obtained the appearance, particle size and stability of the ceramide E emulsifier after diluting it with purified water in different mass ratios. The results show that the ceramide emulsifier prepared by the e...

Abstract

The invention discloses a ceramide E emulsifier as well as a preparation method and application thereof in cosmetics. The ceramide E emulsifier comprises the following components: 0.1-5% of ceramide E, 0-2% of lecithin, 8-25% of a humectant, 5-10% of an emulsifier, 0-2% of an auxiliary agent and the balance of water. The preparation method comprises the following steps: stirring and wetting the lecithin and the ceramide E by using the humectant, heating and dissolving, adding the remaining materials, shearing and dispersing uniformly in a heating state, and treating by using a microjet homogenizer to obtain the semitransparent or transparent ceramide E emulsifier. The ceramide E emulsifier disclosed by the invention has good stability, water dispersibility and biocompatibility, and can be widely applied to the cosmetic industry.

Description

technical field [0001] The invention relates to the field of cosmetic preparation technology, and more specifically relates to a ceramide E emulsifier, its preparation method and its application in cosmetics. Background technique [0002] Ceramides are natural skin lipids that form a water-repellent barrier on the skin's surface, not only helping the skin lock in moisture, but also promoting the skin's self-repairing functions. In addition, it has a strong ability to associate water molecules, and it maintains the moisture of the skin through the network structure formed in the stratum corneum. Therefore, applying the emulsifier containing ceramide on the dry and peeled skin can improve the roughness of the skin, and the skin can restore elasticity and maintain moisture. Although it has moisturizing, anti-inflammatory, anti-allergic, barrier repairing, and anti-aging effects, the premise for its effect to be realized is that the active ingredients can effectively penetrate ...
