Embodiment
[0133] The present invention is described in more detail with reference to Examples and Comparative Examples, but it should be understood that these Examples should not limit the scope of the present invention.
[0134] [Average particle size of emulsion particles]
[0135] Emulsion particles were measured using a submicron particle analyzer (product of Malvern Instruments Co. Ltd.; Mastersizer 2000) for measuring submicron-sized particles by laser diffraction average particle size.
[0136] [Viscosity of organopolysiloxane]
[0137] The viscosity of the organopolysiloxane was measured using a Brookfield Engineering Laboratories rotational viscometer (trademark: Brookfield DV-III super type); measurement stability: 25°C.
[0138] [Appearance of emulsion composition]
[0139] The appearance of the emulsion composition was evaluated by visual observation. Use the following criteria.
[0140] ◎Completely transparent
[0141] ○ Transparent with some cloudiness (i.e. transluc...

Abstract
The invention relates to an emulsion composition, a method for softening fiber structure by using the same and a fiber containing base material processed by the same. The composition comprises the following components in portion by weight: (A) 0.01 to less than 25.0 portions of bi-organic group polyorganosiloxane; (B) 0.01 to less than 20.0 portions of softener; (C) 8.0 to 60.0 portions of water; and (D) 20.0 to 90.0 portions of aqueous solution formed by water soluble mono-hydroxyl groups or polyhydric alcohols, wherein the continuous phase of the emulsion composition is formed by the (C) water and the (D) aqueous solution formed by the water soluble mono-hydroxyl groups or alcohols in a ratio of between 1:0.5 and 1:10, and based on the weight of the emulsion composition, the total content of the components (C) and (D) is 30.0 to 98.0 weight portions.
Description
technical field [0001] The present invention relates to novel emulsion compositions having an aqueous continuous phase consisting of water and a water-soluble alcohol. The novel emulsion composition is further characterized in that it comprises diorganopolysiloxane and softener as emulsion particles emulsified in said aqueous solution. The emulsion composition has good stability and homogeneous appearance after storage for several months. [0002] The present invention also relates to a new softener emulsion composition for fibrous substrates, especially tissue paper. The softener emulsion composition not only imparts a soft feel to human skin to a fibrous substrate treated therewith, but also has excellent slippery, wet / creamy, and comfortable bulky feel. In addition, the fibrous substrate retains a specific water absorbency after treatment with the softener emulsion composition. [0003] The invention also relates to methods of softening fibrous structures using said emul...
