Description

Fabric Softener Composition {FABRIC SOFTENER COMPOSITION}

The present invention relates to a fabric softener composition, and more particularly, to a fabric softener composition that can exhibit excellent reverberation and stability while exhibiting a high flexibility effect, high hygroscopicity and an excellent antistatic effect when the garment is softened.

In general, households are used in addition to the general detergent when washing the home textile softener in order to give anti-static and flexibility to clothing, the amount of use is also gradually increasing. In recent years, consumer interest has been increasing in terms of improving living standards, providing flexibility, which is a basic function of the fabric softener, and anti-static as well as reverberation of clothing remaining after the fabric softener treatment. Indeed, a growing number of households purchase fabric softeners to feel reverberation during washing, clothing wear or clothing storage.

The reverberation that can be felt in clothing after treating the fabric softener provides a dual effect of masking the smell of detergent residues that can be smelled after washing only with detergent, as well as giving a refreshing feeling during or during clothing. However, conventional fabric softeners have been dissatisfied for users who have a high demand for reverberation because such reverberation disappears quickly after washing or after washing.

Microcapsulation of hydrophobic liquids is well known in US Pat. Nos. 3,971,852, 4,446,032, 4,515,705, and the like. Microcapsules encapsulate fragrances, pharmaceuticals, adhesives, dyes, inks and the like, and among them, a method of supporting fragrance in preparing liquid or solid fabric softeners is also well known.

A method for producing a wall of microcapsules containing fragrance is disclosed in US Pat. Nos. 2,800,458, 3,159,585, 3,533,958, 3,697,437, etc., as a coacervation technique. The walls of such conventional fragrance-containing microcapsules are prepared by forming droplets using polyanions and gelatin, such as gum (mara), and many other substrates of walls are known. Microcapsules manufactured using these materials contain fragrances or active substances and are broken by light friction or heat at a specific time, resulting in long-lasting or time releasing effects. To pay.

However, when the microcapsules having a gelatin wall are used in a water-soluble fabric softener composition containing a cationic component having a pH of 7 or less, it is difficult to obtain reverberation due to poor long-term morphological stability and storage stability in the product. have.

The present invention, in consideration of the problems of the prior art, to support the active ingredient of the fragrance or other functional material, and the ability to emit the active ingredient of the fragrance or effective functional material as the manufacturer intended by the time delay effect It is to provide a novel fabric softener composition having a.

Another object of the present invention is to provide a fabric softener composition exhibiting excellent reverberation and stability while exhibiting a high flexibility effect, a high hygroscopicity and an excellent antistatic effect when the garment is softened.

Still another object of the present invention is a fabric softener containing fragrance microcapsules which can be added to a water-soluble fiber softener composition containing a cationic component having a pH of 7 or less as a main component to provide reverberation with excellent long-term form stability or storage stability in a product. It is to provide a composition.

Ii) the active ingredient of the fragrance or functional ingredient supported in the wall

Liquid microcapsules containing

It provides a fabric softener composition comprising a.

Hereinafter, the present invention will be described in detail.

The fabric softener of the present invention is a remarkable improvement in long-term morphological stability and storage stability when a microcapsule having a wall of a gelatin material is contained in a water-soluble fiber softener having a cation component having a pH of 7 or less as a main component.

Accordingly, the present invention is based on a cationic quaternary ammonium salt, and contains a hydrophobic liquid, or liquid microcapsules having a wall of melamine or polyurethane carrying a solid or liquid active ingredient. It greatly improves the long-term stability of the product, and exhibits a specific effect depending on the active ingredients contained, while exhibiting a high-flammability effect, high absorbency and excellent antistatic effect during the flexible treatment of clothing. It is to provide a fabric softener composition showing excellent reverberation when used.

The quaternary ammonium salt is a dialkyl dimethyl ammonium chloride represented by the following general formula (1), a dialkyl imidazolimum salt represented by the following general formula (2), and a dialkyl amidoquater represented by the following general formula (3). There are dialkylamido quaternary ammonium salt, ester quat type and the like, these may be used alone or in combination of two or more. As for content in these compositions, 1-30 weight% is preferable.

[Formula 1]

[Formula 2]

[Formula 3]

In the formulas (1) to (3), each R is alkyl or alkenyl having 8 to 20 carbon atoms.

The liquid microcapsules are manufactured to have a wall after forming droplets using melamine or polyurethane, as in the method of forming droplets disclosed in US Pat. Nos. 2,800,458, 3,159,585, 3,533,958, 3,697,437, and the like. do. Preferably it is desirable to form droplets with polyanions such as gumarabic, polyphosphates, alginates, carrageenan, carboxymethylcellulose instead of gums. , Polyacrylates, silicates (silicates), pectin (pectin), type B gelatin (type B gelatin) and the like can also be used.

The content in the fabric softener composition of such liquid microcapsules is preferably 0.01 to 30% by weight. In addition, the content in the microcapsules of the active ingredient (flavor or functional ingredient) to be supported is preferably 0.005 to 25% by weight based on the total weight of the fabric softener composition. If the content of the microcapsules is less than 0.1% by weight, the content of the active ingredient is low, so that it is difficult to obtain an effect containing the active ingredient, and if it exceeds 30% by weight, it is difficult to obtain a function divergence effect.

Such microcapsules preferably have a diameter of up to 200 μm, a wall of up to 20 μm, and a wall of up to 15 μm in diameter for dispersion in the softener.

The fabric softener composition of the present invention contains a suitable emulsifier to emulsify the cationic flexible component and the microcapsules. As such emulsifiers, nonionic surfactants or cationic surfactants can be used. Nonionic surfactants include polyoxyethylene (2 to 200 moles) alkyl or alkenyl esters and hydroxy fatty acid esters, sorbitan fatty acid alkyl esters and ethylene oxide (15 to 40 moles) adducts thereof having 10 to 20 carbon atoms, polyoxy Ethylene (1-30 mole) alkyl or alkenylamide, polyoxyethylene (1-50 mole) alkyl or alkenylamine, or glyceryl monoalkyl and alkenyl esters and the like. Cationic surfactants include alkyl dimethyl betaine having 8 to 22 carbon atoms, alkyl dimethyl hydroxyethyl, alkyl dimethyl hydroxypropyl betaine and lecithin. It is preferable to use 5-40 weight part of these surfactants individually or in mixture of 2 or more types with respect to 100 weight part of content of cationic flexible component.

The emulsifier of the cationic flexible component is less than 5 parts by weight relative to the content of the cationic flexible component when using a nonionic or cationic surfactant, resulting in poor emulsification stability of the product over time. In addition to stability, the cationic flexible component may interfere with the adsorption of clothing, which may result in inhibiting the softening effect.

In addition, the fabric softener composition of the present invention may contain an organic or inorganic dispersion stabilizer. Preferably, an organic compound such as lower alcohols or glycols having less than 8 carbon atoms, higher alcohols having 14 or more carbon atoms and urea, and inorganic compounds such as magnesium chloride, sodium chloride, calcium chloride, sodium nitrate, etc. may be used alone or in combination of two or more thereof. have. More preferably, at least one selected from the group consisting of ethanol, isopropyl alcohol, ethylene glycol, propylene glycol, hexylene glycol, cetyl alcohol, stearyl alcohol, magnesium chloride, sodium chloride, calcium chloride, and sodium nitrate is used.

The fabric softener composition of the present invention may be added an appropriate amount of additives, such as additional fragrances, preservatives, fungicides, optical brighteners, pigments, antioxidants, antifoaming agents within a range that does not affect product stability, preferably in the composition In small amounts of up to 3% by weight each.
