Abstract: Surfactant-containing seamless capsules of the present invention have an inner layer and an outer layer having a film-forming material. The inner layer contains an oily component and a surfactant component. Such surfactant-containing seamless capsules are produced using a multiple nozzle of triple or more having a sequentially increasing diameter. Since the capsules are excellent in emulsive dispersibility of the content liquid and surfactant dispersibility and solubility in the oily component, they can be used in pharmaceuticals, foods, luxury foods, bath additives, detergents and other fields.

Abstract: PROBLEM TO BE SOLVED: To uniform liquid drops to be formed. SOLUTION: An object liquid for liquid drop formation is sprayed from a porous member 4 having a great number of spray holes 5 into a liquid in a state of continuous phase stored in a container. The sprayed liquid is vibrated and dispersed into the liquid in the state of the continuous phase to form the liquid drops. The great number of the spray holes 5 are arranged in a ring- shaped zone. Several empty zones 6 in which no spray holes 5 are set are formed at intervals in the circumferential direction in the ring-shaped zone in which the spray holes 5 are arranged.

Abstract: PURPOSE:To obtain the subject polymer useful as a low-irritation skin detergent in high recovery with decreased waste water discharge by polymerizing an oxazoline compound, etc., in the presence of a polymerizataon initiator and removing impurities from the product by electrodialysis. CONSTITUTION:The objective polymer is produced by polymerizing a 2-oxazoline compound (e.g. 2-methyl-2-oxazoline) and/or 2-oxazine compound (e.g. 2-methyl-2- oxazine) in the presence of a polymerization initiator (preferably dimethyl sulfate, p-toluenesulfonic acid methyl ester, etc.) and removing the ionic impurities in the reactional product and/or ionic impurities formed in a solution obtained by adding an alkaline agent to the reactional product by electrodialysis.

Abstract: PROBLEM TO BE SOLVED: To uniformalize formed liquid drops. SOLUTION: A liquid to be formed into liquid drops is jetted from a porous member 4 having many jetting holes 5 into a liquid stored in a vessel in a continuous phase state. The liquid drops are formed by applying vibration to the jetted liquid to disperse. Many jetting holes 5 are arrayed in the radial region.

Abstract: PURPOSE:To obtain polymer beads uniform in particle diameter by effecting the polymerization of a suspension formed by dispersing a polymerizable monomer with the aid of a dispersant in an annular space between an outer stationary cylinder and an inner rotary coaxial cylinder at a revolution speed to give a specified Archimedes number and a specified Taylor number. CONSTITUTION:The polymerization of a suspension formed by dispersing drops of a polymerizable monomer (B) in a continuous phase (A) containing a dispersant in the annular space between an outer stationary cylinder 2 and a inner rotary coaxial cylinder 1. The above polymerization is effected under conditions in which the Taylor number as defined by equation II [wherein Rj is the outside diameter of cylinder 1; omega is the angular revolution speed of cylinder 1; d is the width of the annular space; and nu is the kinematic viscosity) lies in the range: 1.16X10 Ar+38.8 ; and in the range: 8.12X10 Ar-367 7X10 (wherein Ar is an Archimedes number as defined by equation I (wherein DELTArho is the difference between the specific gravity of the drop and that of continuous phase (A); Dp is the diameter of a drop; mu is the viscosity of continuous phase A; and g is the gravitational acceleration)]. The above suspension is formed by previously mixing phase A with monomer B in a drop formation apparatus 7. Under above conditions, a Taylor vortex is generated to stabilize the drops, resulting in the formation of beads uniform in particle diameter.

Abstract: PURPOSE:To obtain a granular and/or powdery bathing agent composition capable of favorably emulsifying and dispersing oily component by blending a capsule in which an oily component and surfactant are sealed as bathing agent ingredients with a bathing base. CONSTITUTION:The bathing agent composition is obtained by including a surfactant-containing seamless capsule in which oily component such as oils and fats, wax, hydrocarbons, higher fatty acids, essential oils and a surfactant component, preferably a nonionic surfactant having 7-18, especially 8-13 HLB are sealed as a bathing agent component in a granular or powdery bathing base. The capsule is prepared by continuously each discharging a film-forming liquid from the utmost nozzle, liquids for various kinds of inner layers containing oily components and surfactant components from other nozzles into a vapor phase or liquid phase using at least triple or more multiple nozzle to form a multilayer liquid drop and then curing and gelling the liquid for film-formation of the multilayer liquid drop.

Abstract: PURPOSE:To produce a highly water-absorbing polymer in high production efficiency, preventing the deposition of polymer particles in a reactor, by continuously carrying out polymerization reaction, control of water-content and crosslinking steps in individual reactors. CONSTITUTION:The objective highly water-absorbing polymer can be produced by continuously carrying out the following stage using one or more reactors for each stop. (1) A step to produce a slurry containing polymer phase by dissolving a water-soluble vinyl monomer (e.g. acrylic acid and itaconic acid) and a water-soluble polymerization initiator (e.g. potassium persulfate and sodium persulfate) in water, suspending the obtained aqueous solution in a hydrocarbon (e.g. n-pentane and cyclohexane) and subjecting the dispersion to suspension polymerization. (2) A step to remove water in the polymer phase of the slurry together with the hydrocarbon from the system. (3) A step to add a water-soluble crosslinking agent to the slurry containing the polymer phase and carry out crosslinking reaction in the polymer phase.
