Cellulose ethers are an important class of commercial water-soluble polymers used in construction and construction industries. Cellulose ethers can increase the viscosity of aqueous media. The viscosity-increasing ability of cellulose ether is mainly controlled by its molecular weight, the chemical substituents attached to it, and the conformational characteristics of the polymer chain. Methyl cellulose (MC), methyl hydroxyethyl cellulose (MHEC), ethyl hydroxyethyl cellulose (EHEC), methyl hydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC), Hydrophobically modified hydroxyethyl cellulose (HMHEC) alone or in combination is the most widely used cellulose ether in mortar formulations. The most important properties of cellulose ether polymers include: Good thickening / thickening efficiency Available in a wide range of molecular weight and viscosity Excellent properties as a water-retaining agent Excellent resistance to dissolved inorganic salts Excellent solution clarity Low toxicity and environmental protection Methyl hydroxyethyl cellulose ether(MHEC) is a kind of methyl cellulose derivative which is made from natural high polymer cellulose. It is widely used in many different industries as water retention agent, thickener, adhesive agent and dispersant etc. It could dissolve in water and form a clear solution with specific viscosity. MHEC have a good stability even though in alkaline environment and provide a good stability in heat environment. Widely used in drymix mortar industry, oil drilling, detergent and paint ＆ costings etc.

Ferric chloride CAS:7705-08-0 is the inorganic compound with the formula (FeCl3). Also called Iron(III) chloride, it is a common compound of iron in the +3 oxidation state. The anhydrous compound is a crystalline solid with a melting point of 307.6 °C. The color depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple-red. It has a relatively low melting point and boils at around 315 °C. The vapour consists of the dimer Fe2Cl6 which increasingly dissociates into the monomeric FeCl3 (with D3h point group molecular symmetry) at higher temperature, in competition with its reversible decomposition to give iron(II) chloride and chlorine gas.

It is atripeptide with a gamma peptide linkage between the carboxyl group of the glutamate side-chain and the amine group of cysteine (which is attached by normal peptide linkage to a glycine). Thiol groups are reducing agents, existing at a concentration around 5 mM in animal cells. Glutathione reduces disulfide bonds formed within cytoplasmic proteins to cysteines  , by serving as an electron donor. In the process, glutathione is converted to its oxidized form,glutathione disulfide (GSSG), also called L-(–)- glutathione. Once oxidized, glutathione can be reduced back by glutathione reductase, using NADPH as an electron donor. The ratio of reduced glutathione to oxidized glutathione within cells is often used as a measure of cellular toxicity.
