Disclosed is a high efficiency disinfectant cleaner that is stable and shows antibacterial activity. This disinfectant cleaner basically comprises nanoparticles of silver, copper or gold; at least one surfactant which includes a quaternary ammonium surfactant; a solvent; a gelling agent; and water. Thanks to the use of the gelling agent, the disinfection cleaner remains stable and homogenous. The nanoparticles are kept in suspension, since the gelling agent does not allow deposition of them. Since deposition at the bottom of the solution is prevented, agglomeration to ineffective bigger size particles is also inhibited and the disinfectant stability and efficacy are conserved. The improved stability of the composition and the synergic effect of specific ingredients improve the antibacterial efficiency by decreasing tremendously the required killing contact time.

2-Butoxyethanol is an organic compound with the chemical formula BuOC2H4OH (Bu = CH3CH2CH2CH2). This colorless liquid has a sweet, ether-like odor, as it derives from the family of glycol ethers, and is a butyl ether of ethylene glycol. As a relatively nonvolatile, inexpensive solvent, it is used in many domestic and industrial products because of its properties as a surfactant. It is a known respiratory irritant and can be acutely toxic but animal studies did not find it to be mutagenic, and no studies suggest it is a human carcinogen. A study of 13 classroom air contaminants conducted in Portugal reported a statistically significant association with increased rates of nasal obstruction, the study also reported a positive association below the level of statistical significance with a higher risk of obese asthma and increased child BMI.
2-butoxyethanol can be obtained in the laboratory by performing a ring opening of 2-propyl-1,3-dioxolane with boron trichloride. It is often produced industrially by combining ethylene glycol and butyraldehyde in a Parr reactor with palladium on carbon.
In 2006, the European production of butyl glycol ethers amounted to 181 kilotons, of which approximately 50% (90 kt/a) was 2-Butoxyethanol. World production is estimated to be 200 to 500 kt/a, of which 75% is for paints and coatings and 18% for metal cleaners and household cleaners In the US, it is considered a High Production Volume Chemical because greater than 100 million pounds of this chemical is produced per year.
2-Butoxyethanol is a glycol ether with modest surfactant properties (and it can be used as a mutual solvent). In use since the 1930s, glycol ethers are solvents that dissolve both water-soluble and hydrophobic substances. Glycol ethers consist of two components, an alcohol and ether. According to the nature of alcohol, molecules of this class can be divided into two groups: E series and P series which correspond to ethylene and propylene respectively. Glycol ethers are selected for specific purposes, such as solubility, inflammability, and volatility

In the petroleum industry
2-Butoxyethanol is commonly produced for the oil industry because of its surfactant properties.
In the petroleum industry, 2-butoxyethanol is a component of fracturing fluids, drilling stabilizers, and oil slick dispersants for both water-based and oil-based hydraulic fracturing. When liquid is pumped into the well, the fracturing fluids are pumped under extreme pressure, so 2-butoxyethanol is used to stabilize them by lowering the surface tension. As a surfactant, 2-butoxyethanol adsorbs at the oil-water interface of the fracture. The compound is also used to facilitate the release of the gas by preventing congealing. It is also used as a crude oil-water coupling solvent for more general oil well workovers. Because of its surfactant properties, it is a major constituent (30–60% w/w) in the oil spill dispersant Corexit 9527 which was widely used in the aftermath of the 2010 Deepwater Horizon oil spill
Dipropylene Glycol Monobutyl Ether is a co-product from the manufacture of monopropylene glycol, involving the high temperature and high pressure hydrolysis of propylene oxide (PO) with excess water. It is used as a building block and solvent in a variety of products, in particular in the production of plasticizers, acrylates, UPR resins, DCPD resins and polyurethanes. DPG is also used a solvent in brake fluids, insecticides, lubricants, agricultural and coatings formulations.
Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base, which includes alcohol-water mixtures and low strength acids, make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development, crosslinkers for viscosity enhancement, pH control chemicals, gel breakers for polymer degradation following the treatment, surfactants, clay stabilizers, alcohol, bactericides, fluid loss additives and friction reducer. /Hydraulic fracturing/
Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow, increasing resource production. The preferred coupling agent for many water-based coatings. Used to make acetate esters as well as phthalate and stearate plasticizers. A coupling agent to stabilize immiscible ingredients in metal cleaners, textile lubricants, cutting oils and liquid household products.
Solvent for nitrocellulose resins, spray lacquers, quick-drying lacquers varnishes, enamels, drycleaning cmpd, varnish removers, textile (preventing spotting in printing or dyeing), mutual solvent for "soluble" mineral oils to hold soap in solution and to improve the emulsifying properties.

Propylene series glycol ethers are used in surface coatings, leather, pesticides, electrical, industrial cleaners, resins, and printing inks; [ExPub: ECETOC] Used as a coupling agent (degreasers, paint removers, metal cleaners, and hard surface cleaners), coalescent (latex coatings), solvent (water-reducible coatings), and chemical intermediate (epoxides, acid ester derivatives, solvents, and plasticizers)
In 1991, an estimated 300,000 vapor phase degreasors were installed in the United States. More than 400 million pounds of halogenated hydrocarbons were used in that year. In response to scientific knowledge and governmental regulations, alternate degreasing processes have been developed since the 1970s. D-Limonene has been used as a substitute, and new semiaqueous processes have been installed to reduce exposures in the workplace and pollution of the environment.
Painting (Solvents)
Types of organic chemicals used as paint solvents include aromatic, aliphatic, glycol ethers, chlorinated solvents, terpenes, alcohols, acetates, and ketones. Significant exposure can occur in spray painting and in brushing or rolling. [Burgess, p. 248-50] See "Painting (Pigments, Binders, and Biocides)." See the agent "Occupational exposure as a painter."
Using Disinfectants or Biocides
Disinfectants are chemicals used to inhibit or kill microorganisms. Disinfectants are also called antiseptics or biocides. Disinfectants are generally used in physical media (solutions or on surfaces) while antiseptics are applied to skin or other living tissue. Some of these agents are also used as preservatives for food, drugs, and other domestic and industrial products. Many of these chemicals are skin and respiratory sensitizers. The following can cause occupational asthma: glutaraldehyde, formaldehyde, sodium bisulfite, chloramine T, hexachlorophene, chlorohexidine, benzalkonium chloride, isononanoyl oxybenzene sulfonate, lauryl dimethyl benzyl ammonium chloride, and isothiazolinones. A study of 175 workers exposed to chloramines, aldehydes, and quaternary ammonium disinfectants in the food industry showed increased acute irritation symptoms but not chronic respiratory symptoms.
Application Insights
Coating formulations dominated the market for dipropylene glycol n-butyl ether with a share of 43.4%, in terms of revenue, in 2019. The segment is also expected to witness the fastest growth in the forecast period. This is attributed to the non-VOC characteristics of the product. The global solvent market for coatings has undergone a paradigm shift due to adverse effects on environment resulting from application of volatile organic compounds in crude oil-based solvents. Therefore, companies are shifting their consumption from traditional paints to environmental solvents. DPnB is anticipated to replace PnB (Propylene glycol n-butyl ether) due to its lower VOC emissions.
Demand for coatings is expected to be led by the automotive, construction, and industrial applications. In the automotive industry, demand for coatings is also driven by its consumption for vehicle refurbishing activities and its aftermarket.
Coatings are further gaining traction due to their aesthetic appeal and protective properties, which is anticipated to result in a positive demand for the product over the forecast period
Dipropylene glycol n-butyl ether-based cleaners are thus anticipated to gain preference against oily and greasy stains. In face washes, the solvent dissolves the dust and retains moisture to the skin. The overall market for cleaners is anticipated to witness robust growth due to the potential threat of bacterial and viral diseases. Increasing awareness among consumers to control such diseases is further expected to propel the demand for cleaners. Moreover, product innovations in formulation of cleaners, such as multi-purpose cleaner, are expected to benefit the global consumption of such goods.
Other applications of dipropylene glycol n-butyl ether include manufacturing of printing inks, cosmetics, and agricultural formulations. It is used as a coalescing agent in the production of printing inks. The partial solubility in water makes it a suitable choice in the production of printing inks. When used in pen inks, DPnB allows free flow and prevents color clogging. Printing inks find application in various end-use industries, such as consumer goods, packaging, and electronics.
A cleaning composition comprises a (1) mono-, di- or tripropylene glycol n-butyl ether, (2) a solubilizer and (3) from 35 to 95 percent of water, based on the total weight of the cleaning composition. The solubilizer is a C1-3-monoalkyl ether of mono-, di- or tripropylene glycol, a methyl ether acetate of mono-, di- or tripropylene glycol or a dimethyl ether of mono-, di- or tripropylene glycol. The cleaning composition is very useful for degreasing glass, metallic or polymeric articles.
