Hoshi Chemicals proposes "Pentadecylic", a naturally derived wrinkle-improving ingredient

 Pentadecyl is an oil-soluble powder raw material obtained by extracting, separating, and purifying saturated fatty acid lipids produced by the microalga "aurantiochytrium" belonging to the stramenopile organism group including kelp, wakame seaweed, and diatoms. It started selling in May last year. The origin of Aurantiochytrium has been attracting attention in recent years for producing polyunsaturated fatty acids DHA, EPA, and DPA.

At Sea Act, people indirectly ingest fish such as mackerel and sardines that eat algae such as Aurantiochytrium, and the fat and oil components derived from Aurantiochytrium are used as a nutrient source. Focusing on it, we succeeded in finding a group of substances with extremely high bioactivity in the fats and oils produced by Aurantiochytrium. The above-mentioned pentadecyl has commercialized this group of substances as a useful ingredient for adding cosmetics.

Regarding the wrinkle-improving effect of pentadecyl, a lotion containing 0.1% of a premixed product dissolved in squalane so that the amount of pentadecyl was 1% and a lotion containing no pentadecyl were used as test products, and the effectiveness on human skin was visually evaluated. And image analysis evaluation by replica were performed respectively.


According to the results of visual evaluation, the wrinkle grade was improved by applying the pentadecyl-containing cosmetic solution for 4 weeks, with a significant difference compared to before the application. The amount of change in wrinkle grade after application for 4 weeks was also significantly improved in the pentadecyl-containing cosmetic solution compared with the non-containing cosmetic solution.


As a result of image analysis evaluation by replica, the "maximum wrinkle maximum depth" was reduced by applying the pentadecyl-containing lotion for 4 weeks compared to before the application, and the tendency of wrinkle improvement was observed. On the other hand, when the unblended lotion was applied for 4 weeks, the "maximum wrinkle maximum depth" increased by a significant difference compared to before the application.
