Abstract

Method of fabricating fabric softener And antistatic and softening effect with quaternary salt content. Conditioner is prepared easily by mixing quaternary salt at 30-80 ° C in water. This defect is addressed by a deficiency domestic raw materials for fabric conditioners resources and bypasses the production of deficient fatty amines, diamines or triamines. The resource can be used for laundry fabric softener after washing as a textile adjuvant fabrics production.

Description

The invention relates to a fabric softener with an antistatic and softening effect.

Fabric softeners improve the utility properties of fabrics, ie prevent the formation of electrostatic charges on fabrics or allow faster removal, revitalize the appearance, soften the touch and facilitate washability in subsequent washes. They are applied in the last has a bath for wet washed laundry after removing the remainder of the anionic surfactants from the wash liquor. Commonly used fabric softeners generally contain a quaternary ammonium salt which has an antistatic and softening effect. In some cases, they are combined with nonionic surfactants as emulsifiers. The fabric softeners further comprise perfume, they may contain an optically brightener, colorant, or pearlescent agent.

□ as quaternary compounds are used: dimethyldistearylammonium salts, substituted imidazoline salts, alkyltrimethylammonium or alkylbenzyldimethylammonium salts and alkylmethylbispolyethylene glycolammonium salts, etc. Fatty amines such as n-hexadecylamine, diamines, N or triamines are used as starting materials. N-dimethylethylenediamine or diethylenetriamine. Fatty amines are produced from fatty acids by a synthetic sequence: acid-amide-nitrile-amine. A complex hydrogenation device is required to hydrogenate nitriles to amines. Also, said diamines and triamines are produced in a complicated manner.

The above-mentioned disadvantages are solved by a fabric softener having an antistatic and softening effect, characterized in that it contains 1 to 26% by weight of a quaternary acyl polyglycol alkyltrialkylammonium salt of the general formula (I).

A quaternary salt of formula I wherein R, R, R, R,

X and n as defined above can be readily prepared by reacting the fatty acids with a dialkylaminoalkyl polyglycol or a dialkylaminoalkylalcohol, and the resulting corresponding fatty acid esters are then quaternized with, for example, dimethyl sulfate.

For better handling and pumpability, a solvent such as isopropyl alcohol or diethylene glycol can be added to the end product.

The starting fatty acids can be either pure, eg palmitic or stearic acid, or technical mixtures of fatty acids, i.e. stearin, coconut oil, palm kernel oil, hydrogenated rapeseed oil or beef tallow, can be used,

The fabric softener composition of the invention is prepared readily by mixing the quaternary salt of Formula I at 30 to 80 ° C in water. A nonionic surfactant, a perfume, a colorant and, optionally, an optical brightener are added as desired and the type of application.

Said fabric softener may also be used as a textile fabric auxiliary,

Kterém, in which R, R, R, R, Xan has the meaning given above, reduces the surface resistance of the fabrics from 6.10 µm to 6.10 µm to 2.10 µm depending on the type of fabric at a quaternary salt concentration of 0.4 gl " which is the usual application concentration for these compositions. Commercial fabric softeners reduce the surface resistance to between 2.10 and 8.10 ohms depending on the fabric.

The surface resistance is determined on a Teralin III teraohmmeter supplemented with a stainless steel knife probe in the form of parallel 10 cbits spaced 0.7 c @. The measurement is carried out at a temperature of 20 to 22 ° C and a relative humidity of 60 to 65%.

There is no objective method for evaluating the softening effect. The emollient effect is evaluated subjectively as described »3 -

238 562 (Egan, RR, Am .Am.Oil, Chem. Soc. 55, 1X8 (1978)) by a group of 5 people who evaluate terry cloth by touch and classify them in softness classes 1-5 to scale, where 1 marks the hardest cloth and 5 softest.

Neup untreated cloths and dimethyldistearylammonium chloride treated cloths having an excellent softening effect classified in softness class 5 were chosen as reference standards. it is comparable to the touch achieved by the above-mentioned chloride b and is thus classified in softness class 5,

The following non-limiting examples illustrate the preparation and composition of the fabric softener compositions of the present invention with antistatic and softening properties.

Examples

Example 1

To a 10 m reactor equipped with a stirrer and a heating coil 3000 l of water was charged, heated to 60 ° C and 560 kg of diethyl methyl (2-stearoyloxyethyl) ammonium methosulfate were added with stirring. The mixture was stirred for 1 hour, 4600 L of water and 40 kg of perfume were added. The mixture is stirred for a further 3 hours. A slightly sparkling softener with excellent antistatic and softening effect is obtained, also suitable for use in automatic washing machines. The formulation at an application concentration of 0.4 g.1 reduces the surface resistance to 5.10 to 1.10 ¹⁰ Ohms depending on the fabric. The softening effect is evaluated by softness class 5.

Example 2

In the same manner as in Example 1, 600 kg of dibutylmethyl (2-cocoyoyloxy-1-methylethyl) ammonium methylbosulfate,

water and 40 kg of perfume. A fabric softener with excellent antistatic effect is obtained, suitable for hand rinsing. The composition at the application concentration reduces the surface resistance to 7.10 ° to 2.10 °

Ohm by fabric type.

Example 3 238 582

In the same manner as in Example 1, 560 kg of trimethyl (2-lauroyl-trioxyethyleneoxyethyl) ammonium methosulfate, 7600 L of water and 40 kg of perfume are mixed. The fabric softener properties are the same as in Example 2.

It behaves at 8.10 to 4.10 ^and Ohm depending on the type of fabric.

Example 4

Into the same reactor as in Example 1, 3000 L of water is charged, which is heated to 40 ° C, 500 kg of coconut hexadecylethylene glycol ester and 500 kg of triethyl (2-palmitoyloxyethyl) ammonium ethosulfate are added. 40 kg perfume. A fabric softener with excellent softening and antistatic effect is produced, suitable for hand rinse and rinse in automatic washing machines. At the application end of the composition, the composition reduces the surface resistance from 4.10 to 1.10 Ohms depending on the fabric, the softening effect is classified in softness class 5,

Example 5

3000 L of water was charged to the same reactor as in Example 1, heated to 50 ° C, and 1500 kg of trimethyl (2-caprinoyl-tetraoxypropylene) ammonium methosulfate was added. After stirring for 2 hours, 5370 L of water, 60 kg of perfume and 20 kg of optically brightener premixed in 50 kg of coconut dodecylethylene glycol phosphate are added. A fabric softener with excellent antistatic and good softening effect is produced, suitable for hand rinsing. The composition at the application concentration reduces the surface resistance to 6.10 ° to 1.10 ° Ohm depending on the fabric. The softening effect is evaluated with a softness class of 3 to 3.5.
