Cellulose nanocrystals (CNCs), or nanocrystalline cellulose (NCC), are highly crystalline, rod-like nanoparticles. [6] [7] They are usually covered by negatively charged groups that render them colloidally stable in water. They are typically shorter than CNFs, with a typical length of 100 to 1000 nanometers. [8]
Argyria and staining: Ingested silver or silver compounds, including colloidal silver, can cause a condition called argyria, a discoloration of the skin and organs.In 2006, there was a case study of a 17-year-old man, who sustained burns to 30% of his body, and experienced a temporary bluish-grey hue after several days of treatment with ...
The use of the best biomaterial depending on the application is crucial in the development of drug delivery systems and tissue engineering. The polymer alginate is very commonly used due to its early discovery, easy availability and low cost but other materials such as cellulose sulphate, collagen, chitosan, gelatin and agarose have also been ...
A nanocrystalline (NC) material is a polycrystalline material with a crystallite size of only a few nanometers. These materials fill the gap between amorphous materials without any long range order and conventional coarse-grained materials. Definitions vary, but nanocrystalline material is commonly defined as a crystallite (grain) size below ...
Nanodiamonds are well-absorbed by human skin. They also absorb more of the ingredients in skin care products than skin itself. Thus they cause more of the ingredients to penetrate the deeper layers of the skin. Nanodiamonds also form strong bonds with water, helping to hydrate the skin. [3]
Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...
The cellulose used as a food additive is usually made from wood pulp or cotton lint, according to the Center for Science in the Public Interest, an independent food and health watchdog group.
The equine version of Absorbine is sometimes used by humans, [22] though, anecdotally, its benefits in humans may be because the smell of menthol releases serotonin, or due to a placebo effect. [20] Earl Sloan was a US entrepreneur who made his initial fortune selling his father's horse liniment formula beginning in the period following the ...
