A W/O/W emulsion composition comprising a large amount of silicone oil and having a high viscosity and a high stability is provided. The W/O/W emulsion composition comprises:

W/O/W emulsion composition

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 purpose of the present invention is to provide a water-in-oil type cosmetic which ensures emulsion stability in the case where a volatile hydrocarbon oil component is added, has excellent texture such as not leaving a greasy feeling, and is highly compatible with the skin. The present invention relates to a water-in-oil type emulsified cosmetic comprising:

Water-in-oil type emulsion cosmetic

The present invention provides a water-in-oil emulsion cosmetic that is excellent in the resilient and supple (in other words, firm and tensional) feels and also excellent in the moisturizing effect and feeling in use. The water-in-oil emulsion cosmetic of the present invention is characterized by comprising the following (A) to (D):

The manipulator has two-degree-of-freedom of rotation and gripping, and is capable of ensuring force feedback or force sensation with excellent operationability. A link mechanismis provided between an operation partand a working part. The link mechanismhas four driving rodstoand first and second coupling members of the sane structure,provided at opposite ends of the driving rods. First and second working membersmove correspondingly to the operation of first and second operating memberswith the aid of the link mechanism. The first and second working member can open and close, change the yaw angles and the pitch angles in response to the same action of the first and second operating member through the link mechanism.

A position/force control device includes position detectors on a masterside and on a slaveside. Reaction force estimation observersandestimate reaction force based on outputs of the position detectors. A position control partgenerates acceleration signals a, afor controlling positions on the master side and on the slave side on the basis of the position signals outputted by the position detectors. The operation force control partgenerates acceleration signals a, afor controlling forces applied to the master side and to the slave side based upon the outputs from reaction force estimation observersand. The acceleration composition partcomposes the two sets of acceleration signals a, a, and a, a, and outputs the driving signals for the master side and the slave side.
