The composition with the soothing and moisturizing effects has the specific effects of increasing the water content of the skin, calming and soothing the skin, improving the facial redness condition and reducing the inflammatory response, is very suitable for skin care products, and is mild, free of irritation and good in stability.

The application provides a preparation method and application of a high near-infrared reflective red pigment. 1‑x RE x O5; wherein RE is at least one selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Y, Tm, Yb and Lu. The red pigment is obtained by doping with a rare earth element RE and using a high-temperature solid-phase synthesis method, so that the a* range of the red pigment is changed, and the redness and near-infrared reflectivity of the red pigment are improved.

This invention provides a post-makeup, post-makeup removal, and post-sun exposure repair composition containing purslane extract and its application, belonging to the field of cosmetic technology. The composition of this invention comprises the following components in parts by weight: 1.0–10.0 parts purslane extract, 1.0–8.0 parts fermented mung bean sprout extract, 0.1–3.0 parts immortelle extract, and 0.1–3.0 parts ectoine. This invention uses purslane extract as a soothing and repairing base; fermented mung bean sprout extract to improve oxidative stress after makeup, makeup removal, and sun exposure; immortelle extract to improve redness, burning sensation, and discomfort after irritation; and ectoine to enhance the skin's stress resistance and tolerance. These four components synergistically form a complex care system of "soothing redness—antioxidant stabilization—plant repair—anti-stress tolerance," which can effectively improve problems such as redness after makeup, tightness after makeup removal, burning sensation, stinging, dryness, and unstable skin barrier after sun exposure. The composition of this invention is mild and can be prepared into various dosage forms such as essence water, wet compress water, spray, gel mask, gel, sheet mask, cream mask, serum, lotion, etc., which are suitable for industrial production and daily skin care use.

The invention relates to the technical field of cosmetics, in particular to a moisturizing face cream with a red repairing effect and a preparation method thereof, the moisturizing face cream comprises the following components: an oil phase: artemisia apiacea volatile oil, camellia oil, a repairing nano-carrier, squalane, cetostearyl alcohol and ceramide; and a water phase: deionized water, glycerol, sodium polyglutamate, trehalose and lecithin. According to the repairing nano-carrier, emulsified particles containing repairing components are infiltrated into the carrier in a vacuum impregnation manner, so that the loaded repairing components can stay on the skin for a long time; through water-in-oil emulsified particles with repairing components, the repairing components are wrapped in micro-nanospheres of monoglyceride, and the slow-release effect of the repairing components is further achieved; effective rejuvenating components are carried and permeated into the skin to reach the inflammation position by utilizing glyceride, so that the antianaphylaxis is reduced, the inflammation is prevented, the skin barrier is comprehensively enhanced, couperose skin is effectively removed, and the redness phenomenon is improved.

The invention provides a multi-element composite cerium praseodymium solid solution and a preparation method thereof. The chemical formula of the multi-element composite cerium praseodymium solid solution is Ce1-x-cPrxEcO2 + delta.a (AX). B (GX2), 0.03 < = x < = 0.07, 0 < c < = 0.03, 0 < a < = 0.03, 0 < b < = 0.03, A comprises at least one of Li and Na, G comprises at least one of Mg, Ca, Sr and Ba, E comprises at least one of B and Al, and X comprises at least one of F and Cl. The method comprises the following steps: mixing raw materials according to a stoichiometric ratio, carrying out wet grinding, and drying; the dried raw materials are subjected to sintering treatment at the temperature of 1150-1500 DEG C, and the heat preservation time of sintering treatment is 2-10 h; and grinding and screening the sintered product to obtain the product. According to the method, the cerium praseodymium solid solution compound with relatively high redness can be simply and conveniently obtained.

The invention discloses a sulfur-free big red star anise processing method based on endogenous metabolism precursor regulation and application, mature star anise fresh fruits with yellow peels and full seeds are used as raw materials, and the processing method sequentially comprises three links of ultraviolet stress pretreatment, short-time hot water fixation and segmented drying. Through ultraviolet treatment, red precursor metabolites such as reduced glutathione, phenolic acid, flavone, stilbenes and sugar phosphoric acid are enriched in the fruits; the polyphenol oxidase is rapidly inactivated through short-time hot water fixation, the precursor pool is stabilized, and the quality loss is controlled; in the drying stage, the precursor is promoted to be gradually converted into phenolic acid oxidation products, aromatic aldehyde, aromatic amino acid-containing small peptides and terpenoid aroma substances in a sulfur-free environment, and stable bright red color and typical aroma are formed. Compared with a traditional sulfur fumigation process, the method has the advantages that the bright red star anise with high red brightness, low fruit cracking rate, natural flavor and remarkably reduced sulfur residue risk can be obtained under the condition that sulfur is not used, and the method is suitable for green and safe processing and standardized production of the star anise industry.
