Problems solved by technology

[0004] Current softeners are prone to problems such as agglomeration, delamination, and precipitation in terms of low-temperature stability
Because the use frequency of softener is not high, a bottle of softener will be stored for a long time (1 year or even several years) before it will be used up. It can reach 30°C, and it will drop to -20°C in winter. The large temperature difference leads to a significant impact on stability
The reason is that when the softener returns to room temperature after experiencing low temperature, the cationic surfactant will redisperse from the solidified state to the thawed water, because the main component of the softener, the cationic surfactant, has a high melting point, poor water solubility and slow dissolution , causing cationic surfactants to fail to disperse quickly and evenly when redispersing, resulting in concentration gradients, agglomeration in areas with high cationic surfactant concentrations, and uneven viscosity of the entire system

specific Embodiment approach

[0046] Hereinafter, the technical solutions of the present invention will be described in detail through preferred embodiments, but the scope of the present invention is not limited to these embodiments, which are intended to illustrate the technical solutions of the present invention rather than limit the scope of the present invention. In the following examples, the test methods without specific conditions are usually in accordance with conventional conditions, or in accordance with the conditions suggested by the manufacturer. All percentages and parts are by weight unless otherwise indicated.

[0047] The raw materials used in the examples of the present invention and their manufacturers are shown in Table 1.

[0048] Table 1

[0049]

Embodiment 1

[0051] Weigh 5 grams of triethanolamine ester quaternary ammonium salt and heat it to 50 ° C, then weigh 94.9 grams of deionized water and heat it to 50 ° C, then add the preheated deionized water to the triethanolamine ester quaternary ammonium salt. At 50°C, continue stirring for 30 minutes until the mixture is uniformly dispersed, cool the mixture to 30°C, add 0.1 g of Cassone, and continue stirring for 10 minutes until the mixture is uniformly dispersed, set aside.

Embodiment 2

[0053] Weigh 5 grams of triethanolamine ester quaternary ammonium salt and heat it to 50 ° C, then weigh 94.4 grams of deionized water and heat it to 50 ° C, then add the preheated deionized water to the triethanolamine ester quaternary ammonium salt, and then Add 0.5 g of Tween 20, and continue stirring for 30 minutes at 50 °C until the mixture is uniformly dispersed. Cool the mixture to 30 °C, add 0.1 g of Cassone, and continue stirring for 10 minutes until the mixture is uniformly dispersed. Set aside.

Abstract

The invention provides stable fabric softener composition in a waterborne dispersion form. The composition is prepared from components as follows: (i) a cationic surfactant selected from triethanolamine ester based quaternary ammonium salt, amido amine based quaternary ammonium salt, imidazoline quaternary ammonium salt or a combination thereof; (ii) a nonionic surfactant selected from a polyalcohol type nonionic surfactant, wherein the weight ratio of the component (i) to the component (ii) is (15:1)-(5:1). The invention also relates to a preparation method and an application of the fabric softener composition.

Description

technical field [0001] The invention relates to the field of fabric softeners, in particular to a fabric softener with excellent softening performance, rewetting performance and rheological stability. Background technique [0002] With the improvement of living standards, fabric softener is the main product of fabric care, and more and more consumers are willing to add fabric softener in the process of cleaning fabrics to obtain a more comfortable and pleasant smelling fabric experience, which is very important for fabric softening. The formulation of the agent puts forward more requirements. [0003] Generally, fabric softeners mainly have the functions of fabric softening and providing pleasant smell. However, the current formulations do not pay much attention to the re-wetting property, which leads to some re-wetting problems. You will find that the water absorption slows down. This is because the cationic surfactant with strong hydrophobicity is currently used in the f...
