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]
Tanning beds are used both in dermatology practices for the treatment of cosmetic skin conditions (such as psoriasis, acne, eczema and vitiligo) and in indoor tanning salons for cosmetic tanning. Typical treatment regimens involve short exposure to UVB rays 3 to 5 times a week at a hospital or clinic, and repeated sessions may be required ...
MCC has use in cosmetics as an abrasive, absorbent, anti-caking agent, aqueous viscosity increasing agent, binder, bulking agent, emulsion stabilizer, slip modifier, and texturizer, [4] [5] which can be found in various hair and skin care products as well as makeup. The MCC is a valuable additive in pharmaceutical, food, cosmetic and other ...
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 ...
Practices that enhance appearance include the use of cosmetics, botulinum, exfoliation, fillers, laser resurfacing, microdermabrasion, peels, retinol therapy, [1] and ultrasonic skin treatment. [2] Skin care is a routine daily procedure in many settings, such as skin that is either too dry or too moist, and prevention of dermatitis and ...
Cellulose sulfate (also known as sulfate cellulose or sulfocellulose) The polyanion category of microbicides includes the carrageenans. Carrageenans are a family of linear sulfated polysaccharides chemically related to heparan sulfate, which many microbes utilize as a biochemical receptor for initial attachment to the cell membrane.
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.
Carboxymethyl cellulose (CMC) is used in applications ranging from food production to medical treatments. [9] It is commonly used as a viscosity modifier or thickener and to stabilize emulsions in both food and non-food products. It is used primarily because it has high viscosity, is nontoxic, and is generally considered to be hypoallergenic ...
