Some common examples of bases that are used in commercial surfactant applications are NaOH (giving LABS - linear alkylbenzene sulfonate sodium salt). A salt is formed - ethylammonium bromide. Known neutralized HLASs, such as LABS, however, are lacking in a number of areas. In this Example, 1.5 g of detergent formulation is added to 1.5 g of de-ionized water in a vial which is vigorously hand shaken. Amines are formally derivatives of ammonia. Similar behavior was seen for the DM Amine based surfactant solution.
Then, slowly add HLAS in a drop- wise fashion under agitation, and continue till the mass of HLAS added is 7.5 g. Allow all components of solution to be completely soluble, and let the solution stand overnight. A commonly used class of anionic surfactants are the linear alkylbenzene sulfonic acids ("HLAS"). Further, various surfactants of the invention, when present in unit dose formulations, can mitigate or lower floe formation when interacting with PVOH solutions.
There is then the possibility of another ammonia molecule removing a hydrogen from the positive ion to give a primary amine - ethylamine. The surfactant of any one of claims 1-2 wherein R. 4. Suitable bases to adjust the pH of the formulation, if needed, include mineral bases such as sodium hydroxide and potassium hydroxide; ammonium hydroxide; and organic bases such as mono-, di- or tri-ethanolamine; or 2-dimethylamino-2-methyl-l-propanol (DMAMP).
For the final neutralization step, mix 2.1 g of MEA into solution. A2. For amines one can take advantage of their basicity by forming the protonated salt (RNH 2 + Cl −), which is soluble in water. The detergent packet of claim 5, wherein the detergent formulation further comprises fatty acid salts, one or more additional surfactants, one or more solvents (e.g., propylene glycol and glycerol) and water. In order to create such high active formulations, surfactants molecules are required that can exist in such compact spaces without causing adverse effects to formulation stability. Amines are basic, and mixing them with an acid results in the formation of an amine salt. Still have questions? Determine the amount of steam (in g) needed for the system to reach a final temperature of 48.0°C. Continue mixing until the two surfactants are fully soluble and no aggregates are visible. Draw structures of SF4 in a way that indicates their molecular shape? What is the molecular weight of (-)-amine-(+)-tartrate salt? Mixtures of bases may be used. Some of these adverse effects include increase in viscosity of the formulation, and interactions of the formulation with the encasing polymer (in most cases polyvinyl alcohol (PVOH)), resulting in undesirable gel blobs or undispersed floes. The amine-neutralized anionic surfactants are of the formula I, as described herein. Get your answers by asking now. When the cation of the salt is the protonated amine, the salts are often termed Heat Stable Amine Salts (HSAS). These unit dose products are characterized by high actives concentration, and low water content (typically less than 15 %). Preferably, anionic surfactants have an alkyl group having at least ten carbon atoms and an anionic group, preferably selected from sulfonates and sulfates. US, Ref document number: The amount of fatty acid in the detergent formulation may, for instance, be from 4.5 to 5.5 percent by weight, based on the total weight of the detergent formulation. In a 110 mL glass bottle, add 53. Subsequently, add 2 g of PALMERA B1220 and 2.75 g glycerol while stirring, and wait till fully solubilized. FWIW it is the sum of t5he formula weights of th base and the acid: 6. Of course, ammonium salts, NH_4^(+)X^(-)#, are well known in inorganic … 112017022577, Country of ref document: 1. Unless otherwise indicated, numeric ranges, for instance as in "from 2 to 10," are inclusive of the numbers defining the range (e.g., 2 and 10). Preferably, the sealed package containing the detergent formulation is added to a washing machine. COMPOSITION / INFORMATION ON INGREDIENTS Chemical Name Cas # Percent Or Content(W/W) … The diminishing order of floe appearance is as follows (ranked against MEA with a size index of 100): MEA (100), , DM amine (72), DB amine (50), EB amine (40). Weight percentages (or wt %) in the compositions are percentages of dry weight, i.e., excluding water that may be present in the composition. Under agitation, add 6.39 g of 2-(2-methoxyethoxy)-l-aminoethane until completely solubilized. Aqueous liquid detergent dispersions consisting of a sec-alkane sulfonate and an alkyl hydroxyethyl ammonium salt, Process for the preparation of highly concentrated flowable aqueous solutions of betaines, Antibacterial light duty liquid detergent containing zinc salt, Ultra Concentrated Liquid Laundry Detergent, Ep: the epo has been informed by wipo that ep was designated in this application, Wipo information: entry into national phase. The name " (-)-amine-(+)-tartrate salt" is not specific enough for us to help you. Preferably, a linear alcohol ethoxylate has a C8-C18 alkyl group, preferably C10-C16, preferably C12-C15. Write Its Formula. Given hypothetical elements Q, R, S and T that are found on the same period. Additional surfactants may be included in the detergent formulation. Formulations containing MEA-based surfactants form viscous aggregates. Provided are amine-neutralized anionic surfactants and their use in detergent formulations.
The amount may, for instance, range from 3 g to 35 g. Some embodiments of the invention will now be described in detail in the following Examples. For instance, the formulation may The pH of the solution is then measured, which in this instance is pH = 8.27. 5. Measure the pH of the solution, and adjust by adding MEA if necessary. Recent commercial innovations in the liquid laundry detergent market include "unit dose" products, where detergent components are placed within a water-soluble polymer pouch. Some anionic surfactants are fatty acid salts.
Preferably, the detergent composition comprises no more than 25 wt%, alternatively no more than 15 wt%, alternatively no more than 5 wt%, alternatively no more than 3 wt%, or alternatively no more than 1 wt%, of linear alkylbenzene sulfonates (separate from the amount contributed by the amine-neutralized anionic surfactant of formula I). There has been a tendency to ignore salts where the cation is something else, such as sodium or potassium. Join Yahoo Answers and get 100 points today. Preferably, a linear alcohol ethoxylate contains from six to twelve polymerized units of ethylene oxide, preferably from seven to ten.
