Description

[Detailed description of the invention] FIELD OF THE INVENTION This invention relates to fabric softener compositions.

More specifically, the present invention relates to a fabric softener composition that has excellent stability and has an excellent softening effect on fibers, hair, and the like.

Softening agent compositions provide excellent flexibility for textile products and hair.
It is widely used to impart antistatic properties and smoothness.

Conventionally, fabric softener compositions have been prepared by blending a quaternary ammonium salt such as distearyldimethylammonium chloride, polyoxyethylene alkyl ether or polyoxyethylene alkyl ether, and a solvent such as isopropyl alcohol or ethylene glycol. Although these substances are known to give textile products and hair excellent flexibility, anti-static properties, and smoothness, they can cause viscosity, curling, gelation, and separation when stored for a long period of time. There were problems with stability. Tokuko Showa 5

The method of using the composition of the present invention is not particularly limited, but it is usually used after being diluted with water 100 to 1000 times, or it may be used as it is.

The composition of the present invention can be preferably used as a softening agent composition for textile products and hair. Textile products include natural fibers such as cotton, wool, and silk, recycled fibers such as cotton wool and rayon, semi-synthetic fibers such as acetate, nylon,
Examples include textile products such as knitted fabrics and woven fabrics made of synthetic fibers such as acrylic, polyester, and polypropylene, and various fibers that are a mixture of these fibers, and especially household textile products (underwear, diapers, lingerie, lingerie, sweaters, etc.).

When targeting textile products, it is preferable to apply the fabric softener composition after washing the textile product, but if a neutral detergent is used, it can also be added during the washing bath and applied at the same time as washing.

When used on hair, there are two methods: diluting the composition with water in the proportions mentioned above, and applying it directly to wet hair without diluting it.

In addition to (a) and (b), the fabric softener composition of the present invention may optionally contain ingredients that are generally added to conventional fabric softener compositions, such as polyoxyethylene alkyl ether and polyoxyethylene alkyl phenyl ether. nonionic surfactants; amphoteric surfactants such as stearyldimethylaminoacetic acid betaine; inorganic compounds such as ethanol, propylene glycol, engineered salt, and sodium sulfate; fragrances; colorants; fluorescent dyes; preservatives; can be combined with fabric softener compositions.

The composition of the present invention does not cause separation or gelation even when stored for a long period of time, exhibits extremely good stability, and also has +11 better freeze recovery properties.

(2) Provides good flexibility and smoothness to treated fiber products and hair, giving them a soft texture.

(3) Provides good static protection [L properties] to treated fiber products and hair.

(4) It does not reduce the water absorption of the treated textile product.

It also has this effect.

The fabric softener composition of the present invention is useful as a household textile fabric softener and hair products (hair rinse, hair treatment, hair conditioner).
