Definitions

• This invention relates to an ester quat composition that is used for production of fabric softeners at lower temperatures, when compared to conventional process.
• the dispersion of cationic compounds mainly those suitable for the application in fabric softeners, is a hard task to be achieved at around room temperature, due to the poor solubility/dispersibility of these raw material in cold water.
• the present invention discloses a new option for working with ester quats in the production of fabric softeners, basically consisting of a high concentrated ester quat composition dispersible in water at temperatures of about 35°C.
• ester quats Due to their well-known instability towards hydrolysis reaction, ester quats are rarely formulated as concentrated products in the presence of water, especially when the resulting composition is subjected to storage before final application.
• all advantages of water/ester quat association which promotes the easy dispersibility of the final mixture, can be explored, as hydrolysis is particularly kept under control by the presence of a selected pH modifier.
• ester quats present problems concerning the production of viscous softeners, obliging the use of thickeners to achieve a high viscosity in the final product.
• ester quat concentrate with 75-95% of active content and ethanol and/or glycois up to 100%, is claimed in EP 0 902 008.
• a cosmetic final formulation specifically prepared from the concentrate, is also claimed, but for being a final product, the minimum amount of water required is above the maximum tolerated in the present invention, and the addition of any other additive to keep hydrolysis under control is not mentioned.
• US 5,811 ,385 concentrated aqueous solutions of ester quat suitable for preparing laundry detergents and cosmetics are disclosed. No organic solvents are present in these concentrated aqueous solution.
• US 2003 158 068 discloses fabric conditioning compositions based on ester quats, with maximum total active content of 25%.
• an unsaturated fatty acid is always present as a viscosity stabiliser.
• Final aqueous softener compositions with maximum ester quat concentration of 30% are also claimed in EP 0 669 391.
• the invention disclosed herein regards to a high concentrate ester quat composition, with at least 50% of active matter, indicated as raw material, for easy production of commercial fabric softeners at reduced temperatures.
• the purpose of this invention is to provide concentrated ester quat compositions which contain water and thus can easily be diluted even at lower temperatures. On the same time the detrimental influence of water causing hydrolysis of the ester quat is minimized by the addition of a so-called pH-modifier.
• the invention relates to an ester quat composition essentially consisting of a) at least 50 % by weight of an ester quat compound of the formula 1
• A is a group of the formulas -(CH 2 )n-Q-T1 or
• Q is selected from -O-C(O)-, -C(O)-O-;

• X is an anion, such as chloride, bromide, iodide, fluoride, sulfate, methylsulfate, hydrogensulfate, carbonate, hydrogencarbonate,
• Preferred ester quat compounds of formula 1 are those wherein: Q is -O-C(O)-; R 1 is (CH 2 )n-Q-T 2 or T 3 ; R 2 is (CH 2 )m-Q-T 4 or T 5 or R 3 ; R 3 is d-Ce-alkyl, especially methyl, C 2 -C 6 -alkenyl or C ⁇ -C 6 -hydroxyalkyl, especially hydroxyethyl; T ⁇ T 2 , T 3 , T 4 , T 5 are independently C 8 -C 22 -alkyl or C 8 -C 22 -alkenyl; n and m are 1 or 2.
• ester quats compounds are triethanolamine-diester quats and diethanolamine-diester quats that means compounds of the formula 1 wherein A, R 1 and R 2 are a group of the formula -CH 2 CH 2 OCO-T 1 , R 2 in addition may be a group R 3 , R 2 and R 3 being independently selected R 3 and X being as defined under formula 1. All mentioned ester quat compounds may contain any kind of anion, which is compatible with the ester-quat, the preferred ones are chloride, bromide, acetate, lactate, sulfate, hydrogensulfate or methylsulfate.

In particular, the use of polyethylene glycol having a relative molecular mass between 200 and 600 and in amounts up to 30 % by weight, and of polyethylene glycol having a relative molecular mass between 400 and 600 in amounts from 5 to 30 % by weight is preferred.
• ester quats as cationic compounds
• the presence of water in the concentrate is a real problem, as the ester bonds are broken through the hydrolysis process.
• the best way to avoid it is using a controlled dosage of a pH modifier to increase the pH and thus slowing the hydrolysis significantly.
• the pH modifiers especially indicated to the present composition are amine compounds, especially those selected from the group of triethanolamine, monoethanolamine, ethylenediamine, dialkylamines, dialkyl methyl amines, ethoxylated alkyl amines and aminomethyl propanol.
