The present invention provides a water-in-oil type emulsion cosmetic composition with low viscosity while having excellent stability sufficient to withstand the inclusion of a polar oil. A water-in-oil type emulsion cosmetic composition of the present invention is characterized by comprising: (A) 0.1 to 2 mass % of an organically modified clay mineral; (B) 0.1 to 2 mass % of a hydrophobic silica; (C) 2 to 5 mass % of a silicone-type surfactant; (D) an oil component of which 10 to 50 mass % of the total oil component is a non-polar hydrocarbon oil; and (E) 20 to 60 mass % of a water phase component; wherein the (A) organically modified clay mineral and (B) hydrophobic silica total to 0.2 to 2 mass %; and a viscosity of the cosmetic composition as a whole is 1000 to 10000 mPa&#xb7;s (30&#xb0; C.; B type viscometer).

Water-in-oil emulsion cosmetic composition

The present invention provides a corona-core microgel emulsifying agent composed of a copolymer obtained by polymerizing polyethylene oxide macromonomers, hydrophobic monomers, and cross-linking monomers under specific conditions as well as an oil-in-water emulsified composition characteristically using said emulsifying agent for emulsification. The object of the present invention is to provide a new corona-core microgel emulsifying agent to be used to prepare an oil-in-water emulsified composition that manifests superior emulsification stability, stability over time, and low skin irritation, and is free of stickiness at the time of application, manifests dewy freshness, is free of powdery sensation and/or squeakiness, and is superior in durability of fragrance, as well as an oil-in-water emulsified composition emulsified with said emulsifying agent.

In a circuit for expanding and/or compressing an amplitude of an input signal; a control signal is generated in response to the input signal and supplied to a multiplier circuit for multiplying the input signal by the control signal, a first subtracter subtracts the input signal from the output of the multiplier circuit, a signal processor processes the first subtracter output signal, and a second subtracter subtracts the output signal of the processor from the output signal of the multiplier circuit. The control signal generating circuit includes an envelope detector for detecting the envelope of the output signal of a proceeding absolute value generating circuit and which includes a pre-bit-shifting circuit for bit-shifting the envelope detected output signal by an amount determined by a pre-bit-shifting control signal, a normalizing circuit bit-shifting the output signal of the pre-bit shifting circuit so such that a normalized output signal is generated, the normalizing circuit further generating a bit shift signal representing a bit shift amount required for normalizing a pre-bit shifted signal corresponding to the detected envelope output signal occurring just prior to the current detected envelope output signal being applied to the pre-bit-shifting circuit, and a control circuit supplied with the bit shift signal for generating the control signal supplied to the pre-bit-shifting circuit.
