Abstract

DC60 (08/08/57) This invention describes a skin nourishing gel formulated from triterpenoid extracts of Centella asiatica (Gotu Kola). The gel consists of triterpenoid extract, aloe vera juice, carbopol triethanolamine powder, moringa seed oil, and glycerin. The preparation process involves drying the Centella asiatica leaves, then grinding them finely. Extraction is then performed using ethanol mixed with emulsifiers Tween 80 and PEG 400. The solvent is then evaporated to obtain the triterpenoid extract. This extract is then mixed with glycerin until homogeneous. Next, the water-soluble components (aloe vera juice, carbopol triethanolamine powder) and the oil-soluble components (moringa seed oil) are added, and the mixture is whisked again until a smooth gel is achieved. This results in a skin nourishing gel derived from the triterpenoid extracts. A clear, light green skin nourishing gel formulated from triterpenoid extracts of Centella asiatica leaves. The gel consists of triterpenoid extract, aloe vera juice, carbopol triethanolamine powder, moringa seed oil, and glycerin. The preparation method described in this invention involves drying Centella asiatica leaves and grinding them finely. These are then extracted using ethanol mixed with emulsifiers Tween 80 and PEG 400. The solvent is then evaporated to obtain the triterpenoid extract. This extract is then mixed with glycerin until homogeneous. Next, the water-soluble components (aloe vera juice, carbopol triethanolamine powder) and the oil-soluble components (moringa seed oil) are added, and the mixture is whisked again until the gel consistency is achieved. The resulting skin nourishing gel is clear and light green in color.

Claims (5)

1. The skin nourishing gel formula, derived from Centella asiatica (Gotu Kola) triterpenoid extract, contains: 9% by weight triterpenoid extract, 90% by weight aloe vera juice, 0.01% by weight carbopol powder, 0.01% by weight triethanolamine, 0.9% by weight moringa seed oil, and 0.08% by weight glycerin. 2. The manufacturing process for the skin nourishing gel from triterpenoid extract in Centella asiatica, as per claim 1, involves the following steps: The triterpenoid extract powder is mixed with glycerin until homogeneous. Then, the aqueous solution (aloe vera juice, carbopol triethanolamine powder) and the oil-soluble solution (moringa seed oil) are added. The mixture is then homogenized using a mixer until the gel becomes clear. This results in a light green skin nourishing gel derived from the triterpenoid extract. 3. The process for producing skin care gel from triterpenoid extracts in Centella asiatica leaves, according to either claim 1 or 2, involves selecting mature Centella asiatica leaves, washing them thoroughly with water, and air-drying them at room temperature. The leaves are then cut into small pieces and dried in an oven at 50°C for 48 hours, or until completely dry, before being ground into a fine powder. 4. The process for producing skin care gel from triterpenoid extracts of Centella asiatica, according to either claim 1 or 2, involves the following: Extraction of triterpenoid powder from Centella asiatica by taking dried Centella asiatica powder and extracting it with 70% ethanol, mixed with the emulsifiers Tween 80 and PEG 400 in a ratio of dried Centella asiatica powder to solvent of 1:10. The container is sealed tightly and left to steep at room temperature for 2 days. The mixture is then filtered through No. 1 filter paper to separate the solids. The resulting solution is then evaporated from the solvent using a rotary evaporator at 40°C for 1-2 hours, yielding a dark green triterpenoid extract. This extract is then freeze-dried to remove excess water, resulting in a dry, dark green triterpenoid powder. 5. The process for producing skin care gel from triterpenoid extracts in Centella asiatica leaves, according to either claim 1 or 2, involves preparing the gel mixture. The water-phase solution is prepared by mixing aloe vera juice with carbopol powder to prevent foaming. This mixture is stirred until homogeneous. A small amount of triethanolamine is then added to clarify the gel. All ingredients are stirred again to obtain the water-phase solution. The oil-phase solution is prepared using moringa seed oil.
