Stable alkali liquid abrading agent detergent composition and preparation method thereof

Abstract

The invention discloses a method for preparing a stable alkaline liquid abrasive cleaner composition. The method includes the following steps: dissolving an anionic surfactant in water, and then adding a first alkaline substance thereto to form a solution (A) ; Dissolve the nonionic surfactant, the second alkaline substance and butyl diethylene glycol in another part of the water to form solution (B); Mix solutions (A) and (B) to form solution (C); and The desired stable liquid abrasive cleaner composition is formed by adding abrasive to solution (C) and stirring the resulting slurry until homogeneous. The invention also discloses a stable alkaline liquid abrasive cleaner composition prepared by the above method.

Description

technical field

[0001] The present invention generally relates to a liquid abrasive cleaner. Specifically, the present invention discloses a method for preparing a stable alkaline liquid abrasive cleaner composition, and products prepared by the method. Background technique

[0002] Liquid or semi-solid cleaner compositions containing abrasives are well known in the art and are commonly used to remove all kinds of dirt, especially oil and rust, from hard surfaces such as metal, ceramic or plastic in areas such as kitchens or bathrooms Wait.

[0003] Current liquid or semi-solid abrasive cleaner compositions generally use only water as a solvent, and solid abrasives (water-soluble or water-insoluble) ) remain in a stable suspension state. For example, WO 95 / 08619 discloses a water-based liquid abrasive cleaner composition comprising crosslinked polyacrylate, at least one nonionic surfactant or an anionic surfactant and a nonionic surfactant A combination of pH regulators,...

Embodiment 1

[0040] 7 g of sodium lauryl sulfate was dissolved in 45 g of water, 0.7 g of sodium hydroxide was added thereto, and stirred until uniform to obtain a solution (A-1). In a separate container, 1.8 grams of NEODOL 135-7E (sold by Shell with an average 7EO of C 13 -C 15 Fatty alcohol), 2 g of triethanolamine and 0.5 g of DEnB were dissolved in 15 g of water and stirred until uniform to obtain a solution (B-1). Solutions (A-1) and (B-1) were mixed and stirred until uniform to obtain solution (C-1).

[0041] 28 g of dolomite powder (120 mesh) were carefully added to the solution (C-1 ) under stirring while avoiding aeration of the solution. The resulting slurry was stirred until a stable suspension formed.

[0042] The suspensions were stored at 4°C, 20°C and 35°C for 3 months, respectively, without showing any macroscopic sedimentation. Then, the suspension was subjected to 5 freeze / thaw cycles, which also did not show any macroscopic sedimentation.

[0044] 5.8 grams of dodecylbenzenesulfonic acid and 0.8 grams of Acusol 820 (acrylic polymer produced by Rohm and Haas, 30% solution) were dissolved in 40 grams of water, 0.9 grams of sodium hydroxide was added thereto, stirred until Uniformly, a solution (A-2) was obtained. In a separate container, 2.4 grams of Lutensol TO-7 (C with an average 7EO sold by BASF 13 isomeric alcohol ether), 3 grams of Na 2 CO 3 and 1.2 g of DEnB were dissolved in 15 g of water and stirred until homogeneous to obtain a solution (B-2). Solutions (A-2) and (B-2) were mixed and stirred until homogeneous to obtain solution (C-2). To solution (C-2) was added 0.2 grams of turpentine, 0.5 grams of perfume and 0.2 grams of blue liquid dye.

[0045] 30 g of calcite powder (150 mesh) were carefully added to the solution (C-2) under stirring while avoiding aeration of the solution. The resulting slurry was stirred until a stable suspension formed.

[0046] The suspensions were stored at 4°C, 20°C and ...
