The invention belongs to the technical field of cosmetics, and provides a preparation method of a piper nigrum root extract and application of the piper nigrum root extract in pain relieving cosmetics. The kava pepper root extract is prepared by the following steps: crushing kava pepper roots, and performing alcohol extraction; carrying out secondary extraction by using a small molecular polyol solution containing isopropyl acetate; combining the extracting solutions, and adding compound enzymes (cellulase, pectinase and subtilisin) for enzymolysis to obtain a crude extract; and finally, carrying out subcritical extraction and purification on the crude extract to obtain the product. Through improvement of extraction and purification processes, the extraction rate of active ingredients is effectively increased, a certain amount of glutathione is obtained, and toxicity is reduced; the invention also discovers that the composition ratio of the active ingredients of the extract obtained by the optimized process is in a proper range, and the anti-inflammatory and analgesic effects of the Kava pepper root extract are further improved.

The invention provides a film-forming cool feeling relieving lotion suitable for relieving itching after bite and bald of infants and a preparation method thereof, the film-forming cool feeling relieving lotion comprises a film-forming protection system, the film-forming protection system comprises 5.0-15.0% of polyurethane-35, 5.0-10.0% of polyvinyl alcohol and 0.1-0.5% of agarose, and the film-forming protection system is used for constructing a soft-hard interpenetrating network protection film on the skin surface; the cool feeling system is prepared from 5.0 to 10.0 percent of erythritol and 0.1 to 0.5 percent of menthol lactate; the deep soothing system is prepared from the following components in percentage by weight: 0.1 to 5.0 percent of swertia indica extract, 0.1 to 1.0 percent of radix gentianae macrophyllae extract, 0.1 to 1.0 percent of kava pepper root extract and 1.0 to 5.0 percent of bis-diethoxy diethylene glycol cyclohexane 1, 4-dicarboxylate; and the emulsifying and stabilizing system comprises 0.1-1.0% of a compound of acrylic acid (ester) copolymer sodium and lecithin. By compounding the polyurethane-35 and the polyvinyl alcohol, the problems that a pure polyvinyl alcohol film is strong in shrinkage feeling, easy to crack, tight and painful after being dried are solved; meanwhile, the itching relieving effect of'cooling once being smeared 'can be achieved on the premise that delicate skin of infants is not stimulated.

The present application relates to a kind of multi-effect herbaceous plant composite soothing repair composition and its preparation method, belong to the cosmetic technical field.The present application is by mixing glacial low deuterium water and superoxide dismutase to obtain A component, add D component (specific proportion nicotinamide mononucleotide (NMN) and modified hyaluronic acid microsphere) by the special interaction of the two with low deuterium water, form "triple synergistic carrier system", significantly improve the penetration and stability of active substance;B component is to mix hydroxyl asiaticoside and humectant.Meanwhile, the composite extract prepared by mixing the extract of radix stephaniae tetrandrae, the extract of gentiana and the extract of piper methysticum is C component, after mixing with A, B, D each component, low deuterium water can well carry the active ingredient in plant extract, hydroxyl asiaticoside and humectant in B component are mixed, can give full play to the moisturizing effect.The composition obtained after mixing A, B, C, D component has excellent soothing repair effect.

The invention discloses a soothing and redness removing composition, which is prepared from the following components in parts by mass: 0.5 to 1.5 parts of nerve target point components, 3 to 6 parts of inflammatory target point composition and 1 to 2.5 parts of barrier repairing composition, wherein the nerve target spot component is a PIPER METHYSTICUM root extract, and the nerve target spot component is a PIPER METHYSTICUM root extract. The inflammatory target composition is prepared from the following components: a multi-algae compound extract, a herba portulacae extract and a chamomilla recutita flower extract, the barrier repair composition consists of the following components: a centella asiatica extract, panthenol and a bunge sickle pod wood (EPERUA FALCATA) bark extract. The invention also discloses a jelly film containing the composition for relieving and removing redness. The soothing and redness-removing composition provided by the invention can realize rapid and comprehensive soothing and redness-removing, and is beneficial to barrier repair.

When applied to cosmetics, volunteers who used it experienced rapid results, with significant anti-aging, brightening, and whitening effects, resulting in smooth and delicate skin.

This invention relates to the technical field of cosmetics, and discloses the preparation and application of a supramolecular composition with moisturizing and soothing effects. Using extracts of kava (PIPER METHYSTICUM) leaf / root / stem, milk thistle (SILYBUM MARIANUM) extract, and oat (AVENA SATIVA) extract as core active ingredients, supramolecular encapsulation and spray drying technologies are employed to encapsulate these poorly soluble soothing active ingredients with an encapsulation material. This solves the technical pain points of poor solubility, low transdermal absorption efficiency, and easy loss of activity of single active ingredients. The encapsulated supramolecular composition can deeply penetrate to the basal layer of the skin, soothe damaged skin barrier, and synergistically exert a powerful moisturizing and soothing effect. When applied to cosmetics, it can nourish the skin from the inside out, replenish skin moisture, enhance skin barrier function, and help the skin restore a hydrated, radiant, smooth, and healthy state. Compared with existing single active ingredients, the supramolecular composition of the present invention has significant advantages such as high transdermal absorption efficiency, strong stability of active ingredients, and synergistic effect. It can be widely used in various skin care products such as creams, lotions, emulsions, and masks, as well as related cosmetic systems such as scalp care and body wash.
