Description

Technical Field

[0001] The invention relates to the field of skin care products, and in particular to an anti-acne moisturizing lotion and a preparation method thereof. Background Art

[0002] Nanotechnology is a technology that manipulates atoms and molecules within the spatial scale of 0.1 to 100nm to process materials and give products special functions. As one of the most cutting-edge research hotspots, nanotechnology has penetrated into various industries and fields.

[0003] Acne, also known as pimples, is a chronic inflammation of the sebaceous glands of the hair follicles. The occurrence of acne is related to sebum secretion, excessive angle of the sebaceous gland ducts and infection of Propionibacterium acnes. Acne removal is a comprehensive process that requires regulating oil secretion, improving the keratinization process of the skin, penetrating below the stratum corneum, inhibiting the activity of Propionibacterium acnes, and reducing inflammation to promote the healing of scars. Acne seriously affects beauty and life, so daily skin care cannot be separated from acne products. The acne-removing active ingredients in traditional acne-removing products are mostly retinoic acid drugs, but this type of substance is highly irritating and has a limited range of applications. Nanoemulsion is an alternating dispersion system in which the liquid phase is dispersed in the second phase in the form of droplets. The particle size is between 10 and 200 nm, the system is uniform, and no precipitation or floccules will appear. There have been many reports on acne-removing nanoemulsions generated based on nanotechnology. Chinese patent CN102784085B discloses a composite anti-acne lipid nanoparticle emulsion and its preparation method, wherein a liquid oil phase is prepared from vitex scoparia extract, centella asiatica extract, and tetrahydropiperine, and then the composite anti-acne lipid nanoparticle emulsion is obtained by circulating and homogenizing with distilled water for several times in a high-pressure homogenizer. Chinese patent CN103751231A discloses the use of ginkgo extract nanoliposomes in acne removal and treatment of skin diseases, wherein the ginkgo extract mentioned in the leaves, fruits, outer seed coat, rhizomes, etc. of ginkgo is prepared into nanoliposomes by thin film ultrasound and high-pressure homogenization. The plant nanoemulsion freckle beauty cream disclosed in China's patent CN104606125A is composed of horsetail safflower rapid freckle removal, honeysuckle cypress essential oil killing mites and removing acne and freckle, Niuma vitamin freckle removal, scutellaria baicalensis and angelica anti-aging and anti-wrinkle freckle removal, coix seed and indigo insecticidal willow fungus freckle removal, aloe vera and white tuckahoe acne and scar freckle removal, asparagus and ginkgo leaf color spot and chloasma nanoemulsification freckle beauty cream. It can be seen from the above prior art that the acne nanoemulsion currently used is to nano-crush the active ingredients in the plant to make an aqueous phase, and then mix it with the oil phase to obtain a freckle nanoemulsion. The emulsion system of the nanoemulsion prepared by this method only has emulsion particles, and the stability in dilution and temperature change is poor. The technology is not mature yet and cannot be applied to daily skin care products. Summary of the invention

[0020] The compound essential oil nanocapsules encapsulate aloe essential oil, seabuckthorn fruit extract and mangosteen peel extract as active ingredients, which have the functions of moisturizing, antibacterial, anti - inflammatory and repairing damaged cells to achieve the effect of moisturizing and acne - removing. Made into capsules, taking advantage of the characteristic of slow release of active components, the effective period of the acne - removing and moisturizing lotion is extended. A small amount of nano - silver has the functions of broad - spectrum antibacterial, promoting epithelial regeneration and eliminating inflammation on the skin, and its dispersibility is enhanced when adsorbed on bamboo charcoal microspheres, increasing the stability of the whole system.
