Description

Emulsion composition, method for softening fiber structure thereof and fiber substrate treated therewith

This invention relates to novel emulsion compositions having a continuous phase of an aqueous solution consisting of water and a water soluble alcohol. The novel emulsion composition is further characterized by comprising a diorganopolysiloxane and a softening agent in the form of emulsion particles emulsified in the aqueous solution. The emulsion composition maintains good time stability and a homogeneous appearance for several months during storage.

The invention also relates to novel softening emulsion compositions for fibrous substrates, especially thin paper. The softened emulsion composition provides a soft feeling to human skin and excellent smoothness, moisturizing/moisturizing feeling and comfortable softness to the treated fibrous substrate. In addition, the specific water absorption of the fibrous substrate is maintained after treatment with the softened emulsion composition.

The invention also relates to a method of softening a fibrous structure using the emulsion composition, a fibrous substrate treated therewith, and in particular, a tissue product. The tissue treated by the emulsion composition of the present invention has enhanced softness, smoothness, moisturizing/moisturizing feeling to human skin by incorporating an effective amount of a softener diorganopolyoxyalkylene and a water-soluble alcohol (especially glycerin). The softness, the diorganopolyoxyalkylene and the water-soluble alcohols are applied to a dry tissue web without a drying process. The prepared tissue paper product maintains the specific water absorption of the fibrous paper structure without causing any damage by the processing process.

To soften the tissue product, the tissue paper product is coated with some functional polyfluorene. In this application, the tissue product is also coated with some softening agent and some alcohol such as glycerol.

For example, PCT Patent Publication No. WO 1996/024719 ["SOFT TISSUE PAPER CONTAINING AN OIL AND A POLYHYDROXY COMPOUND" (the procter & gamble corporation)] discloses the incorporation of an effective amount of a polyhydroxy compound applied to a wet tissue web. And oil with thin paper with enhanced looseness and touch softness. The addition ratio of the polyhydroxy compound and the oil of the tissue is 0.01% to 5% by weight of the dry fiber. The polyhydroxy compound and oil include glycerin and polyoxyalkylene oil, respectively.

Japanese Patent Publication No. H-heisei 07-145596 ["COMPOSITION FOR TREATING WIPING PAPER" (Dow Corning Toray silicone Co., Ltd.)] describes a treatment composition for a wet wipe, which is composed of a specific diorganosiloxane. And polyol composition and can be most suitably used to impart flexibility, smoothness and soft touch to the tissue. The patent publication also mentions emulsifying components with a surfactant to prepare an emulsion having more than 50% by weight water. The treatment composition is applied to the dry tissue paper by a drying process, and the coating amount of the composition ranges from 0.2 to 5.0% by weight.

These softening compositions and softening methods are applied to many tissue paper products to improve softness and feel. However, the softness of the tissue paper treated therewith is not sufficient to make the human skin feel good in daily use and the tactile sensation provided by the prepared tissue mainly relates to the softness thereof, and the prior art is not necessarily Satisfactory.

Further, with regard to such softening compositions and softening methods, the inventors of the present invention have found another problem in addition to the insufficient feel of the prepared tissue paper product. The problem is that existing softening compositions (such as oil-in-water emulsions or glycerin addition methods) are used, and some of the natural water-absorbent properties of fibrous paper structures can be destroyed by softening or drying processes. That is, the inventors have discovered that in the prior art, some of the natural and advantageous properties of the fibrous substrate can be compromised to provide some flexibility to the oriented substrate.

The present invention has been explored to solve the above problems, and the inventors have developed novel emulsion compositions comprising (A) diorganopolyoxyalkylene oxide, (B) softener, (C) water and (D) water solubility. a monohydric alcohol or a polyhydric alcohol, wherein the continuous phase of the emulsion composition is an aqueous solution composed of the (C) water and the (D) water-soluble monohydric or polyhydric alcohol in a ratio of 1:0.5 to 1:10, and the group The total content of the component (C) and the component (D) is in the range of from 30.0 to 98.0 parts by weight of the emulsion composition. The inventors have also developed a novel softening emulsion composition comprising the same, and a method of softening the fibrous structure using the emulsion composition, a fibrous substrate treated therewith and a tissue paper product treated therewith.

In particular, the present invention relates to an emulsion composition comprising:

(A) [0.01 to 25.0 parts by weight] diorganopolyoxyalkylene;

(B) [0.01 to 20.0 parts by weight or less] softener;

(C) [8.0 to 60.0 parts by weight] of water;

(D) [20.0 to 90.0 parts by weight] of a water-soluble monohydric or polyhydric alcohol, wherein the continuous phase of the emulsion composition is from (C) water and the (D) water-soluble monohydric or polyhydric alcohol at 1:0.5 to An aqueous solution of a ratio of 1:10, and the total content of the component (C) and the component (D) is in the range of 30.0 to 98.0 parts by weight of the emulsion composition.

The emulsion composition maintains good time stability and a homogeneous appearance for several months during storage. In addition, the emulsion composition provides a soft feel to the treated fibrous substrate as well as excellent smoothness, moisturizing/moisturizing feeling and comfort softness. Natural and advantageous properties such as water absorption are maintained after the fibrous substrate has been treated therewith.

In addition, another drying process and a glycerin addition process may be omitted for the manufacture of the treated tissue paper product because the continuous phase of the emulsion composition consists essentially of an aqueous alcohol solution, preferably a glycerin solution. By using the emulsion composition, the diorganopolysiloxane and the alcohol are applied to the dry tissue web without the need for a drying process.

Although the emulsion composition of the present invention has a similar emulsified state as the oil-in-water emulsion, the emulsion particles comprising (A) diorganopolyoxyalkylene are emulsified in an aqueous solution mainly composed of (D) a water-soluble monohydric alcohol or a polyhydric alcohol.

Depending on the solubility of the (B) softener in an aqueous solution, it may be dispersed in an aqueous solution (a hydrophilic continuous phase), dispersed in an emulsion particle (a hydrophobic oily particle phase) or dispersed as a surfactant.

In summary, the emulsified state of the present invention is extremely stable so that the emulsion composition maintains good time stability and a homogeneous appearance for several months during storage.

In addition, if the softening composition contains a large amount of component (D) water-soluble alcohol (especially ethanol, glycerol or similar lower alcohol), the composition will be highly flammable due to the alcohol.

However, in the softened emulsion composition, the aqueous solution containing (C) water reduces flammability during manufacture, storage and transportation and provides higher safety. This low flammability makes the emulsion compositions of the present invention especially easy to use and safe softening compositions for treating tissue paper products.

Further, a water-soluble component such as a water-soluble ionic surfactant, an aqueous fragrance, an aqueous pigment, or an emollient (such as an aquatic plant extract) may be previously dispersed in (C) water, followed by use in the preparation of the emulsion of the present invention. The composition of the composition is mixed.

On the other hand, since the aqueous solution of (C) water and (D) water-soluble alcohol has a freezing point much lower than that of water itself, the emulsion composition is difficult to freeze in winter in cold regions and provides good freezing/thawing stability. .
