Description

Technical Field

[0001] The present invention relates to a fiber treatment agent composition.

Background Art

[0002] The market for fiber treatment agents has been expanding year by year. In addition to the basic functions of imparting flexibility, antibacterial properties, and antistatic effects to fiber products, in recent years, fragrance has been emphasized, and fiber treatment agents with various fragrances have been sold. Moreover, fiber treatment agents that appeal to new functions by blending skin care ingredients adopted in cosmetics to impart skin care functions (for example, gentleness to the skin and a cool feeling when worn) to the treated fiber products have also been developed. Moisturizing the skin is one of the important skin care functions. Skin care cosmetics for moisturizing (such as lotion, emulsion, and cream) directly applied to the skin can easily obtain a high moisturizing effect, but there are also problems such as being prone to stickiness, taking time to apply all over the body, and being unable to moisturize areas that are out of reach (such as the back). To solve this problem, fiber products that employ skin care fibers kneaded with moisturizing components have been sold. However, skin care fibers have problems such as limited types of applicable fiber products and poor washing durability. Among fiber treatment agents that can impart a skin moisturizing function to the whole of fiber products regardless of the type of fiber products, these problems are solved. In addition, fiber treatment agents containing polyglycerin fatty acid esters are known (Patent Documents 1 and 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor has set as an object to provide a fiber treatment agent that imparts a skin moisturizing function to fiber products and has excellent dispersibility in rinsing water and storage stability.

Means for Solving the Problems

[0005] Unlike skin care cosmetics for moisturizing that are directly applied to the skin, a fiber treatment agent containing a moisturizing component exerts its moisturizing function through a two-step transfer of the moisturizing component (i.e., (1) transfer from the fiber treatment agent to the fiber product and (2) transfer from the fiber product to the skin). The transfer of (1) occurs in the step of treating the fiber product with the fiber treatment agent (the rinsing step after the washing step). Therefore, as a moisturizing component, paying attention to an oily component that is difficult to dissolve in rinsing water and likely to remain on the fiber product, and as a result of intensive studies, the inventor has found that when using polyglycerin fatty acid ester and a specific nonionic surfactant as the oily component and further combining with a water-soluble solvent, the above problems can be solved. The present invention has been made based on this finding.

[0006] That is, the present invention relates to the following [1] to

Examples of ultraviolet absorbers include aminobenzoic acid derivatives (p-aminobenzoic acid, ethyl p-aminobenzoate, glyceryl p-aminobenzoate, amyl p-dimethylaminobenzoate, etc.); salicylic acid derivatives (ethylene glycol salicylate, dipropylene glycol salicylate, octyl salicylate, myristyl salicylate, etc.); cinnamic acid derivatives (methyl diisopropylcinnamate, ethyl p-methoxycinnamate, isopropyl p-methoxycinnamate, 2-ethylhexyl p-methoxycinnamate, butyl p-methoxycinnamate, etc.); benzophenone derivatives (2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid, 2,2'-dihydroxy-4-methoxybenzophenone, etc.); azole compounds (urocanic acid, ethyl urocanate, etc.); and 4-t-butyl-4'-methoxybenzoylmethane, etc. Ultraviolet absorbers are known substances and are readily available on the market or can be prepared. A single type of ultraviolet absorber may be used, or a plurality of types may be used in combination. The content of the ultraviolet absorber is not particularly limited as long as the blending purpose can be achieved, but it is preferably 0.0001 to 5% by mass based on the total mass of the fiber treatment agent composition.

[0039] 〔pH of the fiber treatment agent composition〕 The pH of the fiber treatment agent composition is not particularly limited, but from the viewpoint of storage stability, the pH at 25°C is preferably adjusted to the range of 4.5 to 8.0. The pH can be adjusted by adding a known pH adjuster (for example, citric acid, etc.). The pH can be measured with a pH meter (for example, model MP230 manufactured by Mettler Toledo).

[0040] 〔Viscosity of the fiber treatment agent composition〕 The viscosity of the fiber treatment agent composition is not particularly limited as long as its usability is not impaired, but the viscosity at 25 °C is preferably less than 1000 mPa·s. When the viscosity is less than 1000 mPa·s, the usability (such as handling property when inputting into a washing machine) is good. The viscosity of the fiber treatment agent composition can be measured using a B-type viscometer (manufactured by TOKIMEC).

[0041] 〔Method for producing fiber treatment agent composition〕 The fiber treatment agent composition can be produced according to a known method. For example, the fiber treatment agent composition can be produced by mixing the component (A), component (B), component (C) and optional components. When the compounding components (for example, component (A) and component (B)) are solid under the production environment (for example, at room temperature), it is preferable to heat the component to make it liquid and then mix.

[0042] 〔Method for using fiber treatment agent composition〕 The method for treating fiber products using the fiber treatment agent composition is not particularly limited. For example, it can be used as a softener, a fragrance agent (scenting of fiber products), or an anti-wrinkle agent. However, the treatment method does not include washing. Therefore, the detergent for fiber products is not included in the fiber treatment agent composition of the present invention. As a method of using it as a softener, there are a method of dissolving the fiber treatment agent composition in the rinsing water at the rinsing stage in a washing machine for treatment, and a method of dissolving the fiber treatment agent composition in water in a container such as a tub, and then putting the fiber product and performing immersion treatment. In both cases, the fiber treatment agent composition is diluted by dissolution in water and becomes the concentration of the above-mentioned components (A) to (C), and then is used for treatment of fiber products. When used as a fragrance agent or an anti-wrinkle agent, the application method to fiber products is not particularly limited. For example, the fiber product may be immersed in the fiber treatment agent composition and then air-dried. The type of the textile product is not particularly limited, and examples thereof include shirts, T-shirts, polo shirts, blouses, chino pants, suits, slacks, skirts, jackets, coats, knits, jeans, pajamas, tablecloths, lunch mats, curtains, cushions, floor cushions, sofas, pillow covers, sheets, bed pads, pillows, futons, bed covers, blankets, mattresses, shoes, toilet mats, bath mats, entrance mats, carpets, rugs, and woolen carpets, etc. The material of the textile product is not particularly limited, and examples thereof include natural fibers such as cotton, wool, and hemp, synthetic fibers such as polyester, nylon, and acrylic, semi-synthetic fibers such as acetate, regenerated fibers such as rayon, tencel, and polynosic, and blended products, woven products, and knitted products of these various fibers, etc.
