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]
Aloin, also known as barbaloin, [1] is a bitter, yellow-brown colored compound noted in the exudate of at least 68 Aloe species at levels from 0.1 to 6.6% of leaf dry weight (making between 3% and 35% of the total exudate), [2] and in another 17 species at indeterminate levels [Reynolds, 1995b].
Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium , iron , nickel and silicon ( AlCu(Mg, Fe, Ni, Si) ), often manganese is also included to increase strength (see aluminium-manganese alloys ).
Hydrated silicas can form in nature through biotic processes primarily involving benthic microorganism activity in the oceans. [6] However, there are several abiotic processes that form hydrated silicas, such as precipitating out of solution, forming a diagenetic alteration product, or replacing pre-existing minerals in sedimentary rocks.
Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes ...
This versatile sweater has a style meant for icons, which is probably why Oprah put it on her list. “This is my go-to look—it’s got cuffs, a collar, and a shirttail without the bulk of a ...
This drew another penalty flag for unsportsmanlike conduct. And Branch's day was done. It was a tough turn of events for the Lions in a game with first place in the NFC North at stake.
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 , absolutes or in powder form.
