Ethyl carbamate occurs as colourless or white columnar crystals or granular powder. It is very soluble in water. With heat, ethyl carbamate undergoes decomposition and emits toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides. Ethyl carbamate is used as an intermediate in the synthesis of a number of chemical products, for example, pharmaceuticals, in biochemical research and medicine, and as a solubiliser and co-solvent for pesticides and fumigants. Prior to World War II, ethyl carbamate saw relatively heavy use in the treatment of multiple myeloma before it was found to be toxic, carcinogenic, and largely ineffective.

Chemical properties Methylcellulose occurs as a white, fibrous powder or granules. It is practically odorless and tasteless. It should be labeled to indicate its viscosity type (viscosity of a 1 in 50 solution). Chemical properties Methyl cellulose is a water soluble, gel-like substance with no odor and no taste. The Uses of Methyl cellulose Methyl cellulose is used as a thickener and an emulsifier in various food and cosmetic products; as a gel in advanced cookery and as a lubricant. It is also involved in the treatment of constipation. It acts as a buffer additive in capillary electrophoresis to control electoosmotic flow for improved separations. In paper and textile industries, it is used as a sizing, thereby protecting the fibers from water or oil. The Uses of Methyl cellulose Thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders, lubricants, steric stabilizer and water retention aid. The Uses of Methyl cellulose As a substitute for water-soluble gums; to render paper greaseproof, in adhesives, as thickening agent in cosmetics, as protective colloid in emulsions, as binder and stabilizer in foods. As fat replacer in the formulation of dietetic foods. Pharmaceutic aid (suspending agent). The Uses of Methyl cellulose Methylcellulose is a gum composed of cellulose in which the meth- oxyl groups replace the hydroxyl groups. it is soluble in cold water but insoluble in hot water. solutions increase in viscosity upon heating, gel at 50–55°c, and liquefy upon cooling. it is used in baked goods for moisture retention, and in fruit pie fillings for the reduction of water absorption into the pie crust during baking. it is also used in breaded shrimp where it functions to form an oil barrier film.

LD 50 (Rat): > 5 g/kg .Hypromellose is considered low toxicity to non-toxic .Adverse events may include blurred vision and contact dermatitis . Hypersensitivity and intolerance reactions may occur (for example, eye burning, pain, increased lacrimation, a sensation of foreign body, conjunctival hyperemia, eyelid swelling, pruritus). The stickiness sensation of the eyelids, the decreased sense of smell, photosensitivity . Chemical properties Hypromellose is an odorless and tasteless, white or creamy-white fibrous or granular powder. This product is soluble in water (10 mg/ml). However, it is very important to thoroughly disperse the particles in water with agitation before they will dissolve. Otherwise, they will lump and form a gelatinous membrane around the internal particles, preventing them from wetting completely. There are four dispersion techniques commonly used to prepare solutions of hydroxypropylmethylcellulose: dispersion in hot water, dry blending, dispersion in non-solvent medium, and dispersion of surface-treated powders. The Uses of Hydroxypropyl methyl cellulose Hydroxypropyl Methylcellulose is a gum formed by the reaction of propylene oxide and methyl chloride with alkali cellulose. it will gel as the temperature is increased in heating and upon cooling will liquefy. the gel temperature ranges from 60°c to 90°c, forming semifirm to mushy gels. it is used in bakery goods, dressings, breaded foods, and salad dressing mix for syneresis control, texture, and to provide hot viscosity. usage level ranges from 0.05 to 1.0% Background Hypromellose, or hydroxypropyl methylcellulose (HPMC) , is a semisynthetic, inert, and viscoelastic polymer that forms a colloid solution when dissolved in water. It acts as a thickening agent, coating polymer, bioadhesive, solubility enhancer in solid dispersions, and binder in the process of granulation and in modified release formulations . It is a commonly used as a delivery component in oral pharmaceutical products that provides the release of a drug in a controlled fashion, effectively increasing the duration of release of a drug to prolong its therapeutic effects . Hypromellose is also found in eye drops as a lubricant . Production Methods A purified form of cellulose, obtained from cotton linters or wood pulp, is reacted with sodium hydroxide solution to produce a swollen alkali cellulose that is chemically more reactive than untreated cellulose. The alkali cellulose is then treated with chloromethane and propylene oxide to produce methyl hydroxypropyl ethers of cellulose. The fibrous reaction product is then purified and ground to a fine, uniform powder or granules. Hypromellose can then be exposed to anhydrous hydrogen chloride to induce depolymerization, thus producing low viscosity grades..Hydroxypropyl methyl cellulose is used as an ophthalmic lubricant, an emulsifier and a thickening and suspending agent. It is widely used as an excipient in pharmaceutical formulations. It acts as a food additive. Its eye drops are known as artificial tears, which are used to relieve eye dryness and soreness. It finds applications in various fields as emulsifier, film former, protective colloid, stabilizer, suspending agent, or thickener in foods. Pharmaceutic aid (suspending agent; tablet excipient; demulcent; viscosity increasing agent); hydrophilic carrier in drug delivery systems. In adhesives, asphalt emulsions, caulking compounds, tile mortars, plastic mixes, cements, paints.
