Aloe vera gel is used commercially as an ingredient in yogurts, beverages, and some desserts, [54] but at high or prolonged doses, ingesting aloe latex or whole leaf extract can be toxic. [5] [9] [11] [15] Use of topical aloe vera in small amounts is likely to be safe. [9] [39]
Extracted egg oil. In alchemy, the oil was traditionally extracted from the yolk by a fairly simple process, [3] [failed verification] by which fifty eggs yielded approximately five ounces of oil. [4] Modern methods of production include liquid–liquid extraction [5] using common solvents such as hexane, [6] petroleum ether, chloroform, and ...
The salicylate portion of the molecule absorbs ultraviolet light, protecting skin from the harmful effects of exposure to sunlight. The ethylhexanol portion is a fatty alcohol , adding emollient and oil-like (water resistant) properties.
In the context of electron transfer, these groups enhance the oxidizing power tendency of the attached species. For example, Tetracyanoethylene serves as an oxidant due to its attachment to four cyano substituents, which are electron-withdrawing groups. [5] Oxidants with EWGs are stronger than the parent compound.
An extract (essence) is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water. Extracts may be sold as tinctures or absolutes or dried and powdered.
The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)
cis-3-Hexen-1-ol, also known as (Z)-3-hexen-1-ol and leaf alcohol, is a colorless oily liquid with an intense grassy-green odor of freshly cut green grass and leaves. It is produced in small amounts by most plants and it acts as an attractant to many predatory insects .
Tea tree oil, also known as melaleuca oil, is an essential oil with a fresh, camphoraceous odour and a colour that ranges from pale yellow to nearly colourless and clear. [ 1 ] [ 2 ] It is derived from the leaves of the tea tree, Melaleuca alternifolia , native to southeast Queensland and the northeast coast of New South Wales , Australia.
