This invention discloses the application of an artemisia annua compound as the sole active ingredient in the preparation of topical formulations for the prevention or improvement of blackheads and acne. Based on 100% of the total mass of the topical formulation, the artemisia annua compound accounts for 0.1% to 0.22%, and is composed of the following raw materials in parts by mass: camphene 4 to 10 parts, artemisinin 1 part. This invention also discloses a topical formulation for the prevention or improvement of blackheads and acne, the sole active ingredient of which is an artemisia annua compound. Based on 100% of the total mass of the topical formulation, the artemisia annua compound accounts for 0.1% to 0.22%, and is composed of the following raw materials in parts by mass: camphene 4 to 10 parts, artemisinin 1 part. The artemisia annua compound of this invention can significantly reduce the formation of squalene peroxide in a UVA-induced squalene photo-oxidation model, and shows stronger inhibition against Malassezia and less impact on Staphylococcus epidermidis in a Malassezia vs. symbiotic bacteria comparison model.

The application relates to the field of organic synthesis and discloses a method for continuously producing camphene aldehyde from pinene by one-step method and application of the method, which comprises the following steps: continuously feeding an organic solution of alpha-pinene and neutral organic peroxide into a reactor in the presence of a main catalyst A and an auxiliary catalyst B to perform continuous contact reaction, wherein the main catalyst A is an oxidation catalyst, and the auxiliary catalyst B contains alkali metal and / or alkaline earth metal. According to the method, camphene aldehyde can be directly produced from pinene by one-step method of epoxidation and isomerization rearrangement reaction, and the selectivity and yield of the camphene aldehyde product are relatively high. The method avoids complicated operation steps such as rectification purification required by a two-segment reaction process, reduces the reaction process, and simultaneously adopts a continuous production process, so that production is efficient, convenient and stable.

This invention discloses a poly(4-methyl-1-pentene) aerogel, its preparation method, and its applications. By using camphene as a solvent for poly(4-methyl-1-pentene), a thermally induced phase separation process is initiated by controlling the cooling rate, followed by conventional drying to obtain a white aerogel with good self-supporting properties. The preparation method is simple and mild, requiring no complex processes or expensive equipment, and can be produced on a large scale. The aerogel possesses a rich microporous structure and extremely high solar reflectivity, making it suitable for radiative cooling for passive cooling. Furthermore, the aerogel prepared by this method exhibits excellent superhydrophobicity and thermal insulation properties, enhancing its potential for outdoor applications.

The application provides a detoxification and repair medical dressing for treating and relieving stubborn vulvar leukoplakia and a preparation method thereof, and relates to the technical field of gel dressings. The medical dressing is composed of a gel component and a composite antibacterial repair component, and the composite antibacterial repair component is composed of modified corn starch, anise camphene, eugenol, algal polysaccharide and Gynura japonica fermented inactivated extract. The Gynura japonica fermented inactivated extract is obtained by fermenting Gynura japonica with Bacillus subtilis and lactic acid bacteria and then inactivating. The application overcomes the shortcomings of the prior art, can effectively relieve itching during the treatment of vulvar leukoplakia under the premise of having an antibacterial effect, shortens the overall treatment cycle, and improves the comfort of treatment.
