TH22868U - Process for extracting active ingredients from seaweed - Google Patents

Abstract

24/06/2021 (OCR) The process for extracting active ingredients from algae involves grinding the algae into small pieces, extracting the compounds with ethanol, and stirring the algae in a solvent with a mixer. The solution is then drained, filtered, evaporated under vacuum, and solidified in a centrifuge. Freeze-dried to obtain a dry powder extract, which can replace chemical sunscreens. This extraction yields an active ingredient in algae with a sun protection factor (SPF) of 30. It also slows skin deterioration caused by sunlight and is non-toxic to skin cells, making it suitable for use as an ingredient in cosmetic products. 11/08/2020 (OCR) A new method for extracting active ingredients from algae involves grinding the algae into small pieces, extracting the compounds with ethanol, and stirring the algae in a solvent with a mixer. The solution is then drained, filtered, evaporated under vacuum, and solidified in a centrifuge. Freeze-dried to obtain a dry powder extract, which can replace chemical sunscreens. In order to obtain the active ingredient of algae that has sunscreen effect with SPF value equal to 30 and has the effect of delaying skin deterioration caused by sunlight and is not toxic to skin cells, it is suitable for use as an ingredient in cosmetic products. Page 1 of 1 page Summary of the invention The method for extracting the active ingredient from algae that has the effect of preventing and reducing skin damage caused by sunlight consists of the steps of grinding the algae into small pieces, then extracting the substance with ethanol, then stirring the algae in the solvent with a stirrer, pouring out the solution and filtering the solution, evaporating it under vacuum, and solidifying it with a cold blender, and freeze-drying it to obtain a dry powder extract that can replace the use of chemicals in sun protection. To obtain the active ingredient of algae that has sunscreen effect with SPF value (sun protection factor SPF) equal to 30 and has the effect of delaying skin deterioration caused by sunlight and is not toxic to skin cells, it is suitable for use as an ingredient in cosmetic products.
