The invention provides a neutral water-based cleaning agent and a preparation method thereof. The neutral water-based cleaning agent comprises the following components in percentage by mass: 0.5-1.5%, preferably 1%, of aliphatic alcohol alkoxy surfactant, 1-5%, preferably 3%, of aliphatic alcohol polyoxyethylene ether surfactant, 1-5%, preferably 3%, of ployether surfactant, and 0.5-1%, preferably 0.7%, of linear alkyl benzene sodium sulfonate. In the invention, as nonionic surfactants are compounded with anionic surfactants, surface tension of the cleaning agent is reduced, and pH of the cleaning agent is kept neutral; the neutral water-based cleaning agent disclosed by the invention has a good cleaning effect on polar and nonpolar pollutants, and can achieve an unexpected beneficial effect in cleaning slits by adopting physical cleaning means such as ultrasonic cleaning, high-pressure spraying, brushing and the like.

Provided herein are various methods for forming alkylaromatic sulfonate compositions and blended alkylaromatic sulfonate compositions, and such compositions themselves. The methods of various embodiments include obtaining a C8-C30 hydrocarbon mixture, optionally treating the mixture to concentrate the mixture in sulfonatable aromatics, and sulfonating the mixture to form the alkylaromatic sulfonates. The mixture or treated mixture may be blended with linear alkyl benzene (LAB) compositions and sulfonated, and / or the alkylaryl sulfonates may be blended with linear alkylbenzene sulfonate (LAS) compositions, to form the blended alkylaromatic sulfonates of some embodiments. These compositions and processes for making them may be tailored to serve a variety of end uses, such as detergents in cleaning solutions or for enhanced oil recovery operations, and / or as low foaming and / or hydrotropic additives in detergent formulations, and the like.

The invention is directed to mixtures comprising C10-C14 linear alkylphenyl sulfonates with alkyl groups having a biobased content of at least 50%. These C10-C14 linear alkylphenyl sulfonates are used in consumer product cleaning and personal care compositions (e.g., dishcare, laundry, hard surface cleaners, shampoos, conditioners, and soaps). The invention is further directed to a method of making a mixture of partially or wholly bio-based C10-C14 linear alkylphenyl sulfonates with alkyl groups having a particular bio-based content.

A free flowing aqueous lamellar gel laundry detergent liquid comprising, in addition to water: a) 20 to 35 wt % of a surfactant system in the form of vesicles comprising potassium neutralised linear alky benzene sulfonate anionic surfactant (LAS), alkyl ether sulphate anionic surfactant (AES) and nonionic surfactants, b) at least 3 wt % of a first nonionic polymeric material (EPEI) which is a water-soluble fabric cleaning polymer; c) from 0.1 to 1 wt % of a second nonionic polymeric material (Pluronic) which is a tri-block polymer with a hydrophobic midblock and two hydrophilic end-blocks with an HLB of at least 20 d) optionally, a polyester soil release polymer and e) optionally, at least 2 wt % 1-hydroxyethane 1,1-diphosphonic acid (HEDP).

The invention discloses efficient low-foam normal-temperature phosphorous-free oil removing liquid. The oil removing liquid consists of the following components in percentage by weight: 3.0-7.0 wt% of alkylphenol polyoxyethylene ether, 1.0-5.0 wt% of fatty alcohol polyoxyethylene ether, 1.0-5.0 wt% of fatty acid methyl ester polyoxyethylene ether sulfonate, 0.5-4.0 wt% of linear alkylbenzene sulfonate, 10.0-30.0 wt% of carbonate, 4.0-15.0 wt% of sodium metasilicate pentahydrate, 5.0-15.0 wt% of sodium hydroxide, 4.0-12.0 wt% of sodium citrate, 0.5-1.0 wt% of redeposition resisting agent, 2.0-5.0 wt% of complexing agent, 0.1-0.3 wt% of defoaming agent, 1.0-3.0 wt% of corrosion inhibitor, 0.01-0.1 wt% of flocculating settling agent, and the balance of water. The oil removing liquid has the characteristics of cost saving, improvement of oil removing efficiency and economic benefit.

The invention discloses a normal-temperature nonphosphorus degreasing agent for metal surface processing and a preparation method thereof. The normal-temperature nonphosphorus degreasing agent comprises the raw material percentages by weight: 10-20% of sodium hydroxide, 5-10% of sodium metasilicate, 3-5% of sodium carbonate, 6-8% of alkylphenol polyoxyethylene, 2-4% of linear alkyl benzene sulphonate, 1-2% of 2-butoxyethanol, 0.5-1% of polyether and the balance of water. Compared with the prior art, the normal-temperature nonphosphorus degreasing agent has the characteristics of normal temperature, environmental protection (non phosphorus), high efficiency, safety, low foam, solubilization, good decontaminability and the like, and does not corrode steel plates, aluminum, copper, plastics, rubber and the like.

The invention discloses a sulphuric acid plant liquid and liquid heat exchanger on-line cleaning method, which relates to the sulphuric acid production. The invention is characterized in that sulfamic acid, surface active agents and corrosion and scale inhibitors are selected as cleaning scale removing liquid according to ingredients of water side scale of a heat exchanger. A concrete recipe comprises 5 to 10 percent of sulfamic acid, 0.1 to 0.3 percent of surface active agents, 0.1 to 0.4 percent of corrosion inhibitors Lan-826 and the balance water. The method comprises the following steps: filling clean water in a scale removal preparation tank; placing the reagents into water to be prepared into scale removal cleaning liquid with the pH between 1.5 and 2.5; then, circularly injecting the scale removal liquid into the water side of the exchanger by a cleaning pump under the condition without a stop; and controlling the pH value of the cleaning scale removal liquid until a structure is cleanly cleaned. The sulfamic acid in the cleaning scale removal liquid is a high-grade product with the mass percent higher than or equal to 99.8 percent, the surface active agents are sodium n-alkylbenzenesulfonate, and the corrosion inhibitors (Lan-826) have major ingredients of organic nitrogenous compounds. The method of the invention has the advantages of easy acquisition of raw materials, simple and convenient operation and high scale removal efficiency, and is applicable to sulphuric acid production enterprises.
