Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, in particular to a long-lasting cosmetic composition. Background Art

[0002] A cosmetic composition is a formula for a product that is applied to the skin, hair or other parts of the body to improve appearance, fragrance or cleanse the body. A composition is a mixture of multiple ingredients, each of which performs a specific function, which together form a stable, effective and safe product.

[0003] Existing cosmetic ingredients often contain heavy, low molecular weight silicone oils, etc. For users with oily skin, the oil secretion will cause the cosmetics to slide or fall off, making the makeup easy to come off, especially in hot or humid environments, and the makeup lasts for a short time. Therefore, a long-lasting cosmetic composition is proposed.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0015] The preparation method of the cosmetic composition comprises the following steps:

[0016] Step 1: Mix and preheat the oil component and emulsifier, and mix and heat the aqueous component;

[0017] Step 2: Slowly add the preheated oil components into the hot water phase, stir evenly, and use an emulsifier to fully emulsify the mixture until a uniform emulsion is formed;

[0018] Step 3: While the emulsion is cooling, gradually add microencapsulated hyaluronic acid and silicate microcapsules and stir evenly;

[0019] Step 4: After the emulsion is cooled, add the adaptive polymer and the fluorinated polymer, continue stirring, adjust the pH value of the emulsion, add the preservative, and finally, fill the emulsion into a container.
