历史上化工板块受到原油价格影响较为明显：考察在油价上涨期间不同化工品对油价的敏感性和传导能力，我们回溯了2000 年以来历次油价大幅上涨期间不同化工品板块的价格和股价变动情况。化工板块的股价表现受到原油供需与自身供需的双重影响，在油价上涨的前期阶段，由需求拉动下的原油价格上涨能较好地传导至化工品板块，带动股价表现较佳，而在后期阶段由事件催化的油价上涨则可能给更多地给化工品带来成本压力，股价相对前期走弱，此外，化工品自身供给的扰动也会对油价上涨的传导能力形成影响。

Disinfecting is a procedure that uses chemicals/disinfectants to kill germs on surfaces and objects. Some common disinfectants include bleach and alcohol-based solutions. Disinfectants are usually left on target surfaces and objects for a certain period to kill germs. Also, the task of sanitizing can involve either cleaning or disinfecting or both. According to the Center for Disease Control and Prevention (CDC), sanitizing refers to lowering the number of germs on the surface to a safe level. The safe level depends on public health standards or requirements at workplaces, such as healthcare facilities. Some common ways of disinfecting and sanitizing include mopping a floor using a mop with disinfectants and water, disinfectant wipes or hand sanitizers, and others.

Over the past years, cleaning products have become part and parcel of a consumer’s life. Consumer awareness is also growing every year, which is why manufacturers are focusing on elevating the quality of cleaning products with the best possible environmental conditions. Today's consumer is not just concerned about maintaining hygiene or cleanliness at a personal level but also keen on reducing the chances of infections in his/her surroundings. So, to fulfill the hygiene needs at home as well as at commercial places, different ingredients are used in cleaning products.

Degreasers are used to clean various types of equipment and machinery; they are used to clean or remove dirt, dust, and any foreign particles, and can be used for both residential or industrial purposes. Industrial degreasers are used to clean motor parts, machinery, and heavy equipment that are used in various end-user industries. They are powerful solvents that can handle numerous types of manufacturing parts, components, and heavy machinery. Hazardous substances such as paints, grime, grease, oil, lubricants, dirt, dust, corrosion, and sticky films that get accumulated over machines can easily be removed by using industrial degreasers. Industrial degreasers will remove these foreign particles as well as increase the shelf life of machines or equipment.

Oleochemicals are chemicals derived from plant and animal oils. Oleochemicals include the formation of basic oleochemical substances like fatty acids, fatty alcohols, glycerine, methyl esters, and others. Intermediate chemical substances produced from the basic oleochemical substances include alcohol ethoxylates, alcohol sulfates, alcohol ether sulfates, quaternary ammonium salts, monoacylglycerols, diacylglycerols, structured triacylglycerols, sugar esters, and other oleochemical products. Oleochemicals are biodegradable, eco-friendly, and less toxic. The major oleochemicals are fatty acids, fatty alcohols, methyl esters, and glycerines, which are referred to as basic oleochemicals.

Oral health is a vital part of overall general health, and therefore, good oral health is indicative of overall wellness. Most diseases start from the oral site and spread to the entire body. Although some of these oral infections are preventable, some are not, and therefore, taking care of oral health is of paramount importance. The lack of proper oral hygiene accelerates the growth of microbes and causes various dental disorders, such as halitosis and dental caries.

Nanofiltration (NF) is a membrane filtration-based process or liquid-separation technology that uses membranes with nanometer-sized pores to remove dissolved contaminants. NF membranes have pore sizes ranging from 1-10 nanometers, which is smaller than membranes used in microfiltration and ultrafiltration. However, the size of NF membranes is larger than RO membranes. NF membranes offer high rejection of multivalent ions (such as calcium) and low rejection of monovalent ions (such as chloride). The nanofiltration technology is used to recycle wastewater due to high flux rates and relatively lower energy consumption than RO technology. In addition, NF is often employed in the manufacturing process for pharmaceuticals, textiles, dairy products, and baked goods.

Over the last few years, personal care products have become part and parcel of consumer’s life. It includes array of product such as soaps, liquid soaps, hair gel, hair oil, shampoos, anti-aging face creams, sunscreen products and others. Chemicals used in personal care products range from basic metallic salts and fatty acids used in ordinary bath soaps to the high-end cosmeceuticals that offer beautifying properties of cosmetics with useful benefits of pharmaceuticals and chemicals.

Plastics have become an inseparable part of modern lifestyle since their formation. Plastics are used for packaging, building and construction, automotive, consumer goods, electronics, and medical devices. To make plastics usable and to increase their processability, plastic additives are required to modify polymer resin. This helps in enhancing several characteristics that manifold the value of plastic materials. Various types of additives such as flame retardants, heat stabilizers, lubricants, and slip additives, blowing agents, antistatic agents, antioxidants, and light stabilizers are used for the modification of polymer resins.
