Title
(EN) OIL-IN-WATER-TYPE EMULSION COMPOSITION AND COSMETIC
(FR) COMPOSITION D’ÉMULSION DE TYPE HUILE DANS L'EAU ET PRODUIT COSMÉTIQUE
(JA) 水中油型乳化組成物及び化粧料
Abstract
(EN)
An oil-in-water-type emulsion composition produced by emulsifying and dispersing a paste-like silicone composition with and in a polyoxyethylene sorbitan fatty acid ester, wherein the polyoxyethylene sorbitan fatty acid ester has the number of ethylene oxide (EO) units added of 15 or more and a HLB value of 11 or more, and the paste-like silicone composition is composed of an addition polymerization product of organohydrogen polysiloxane and a compound containing an alkenyl group and a liquid oil. The oily component in the oil-in-water-type emulsion composition can be emulsified satisfactorily, and the storage stability of the oil-in-water-type emulsion composition is good. Furthermore, the polyoxyethylene sorbitan fatty acid ester is approved as a food additive, has little harm to human bodies, and is therefore suitable for skin care purposes, particularly for use in lipsticks. Therefore, when the polyoxyethylene sorbitan fatty acid ester is added to a cosmetic such as a skin toner and a lipstick, the irritation of the cosmetic to skin is weakened, the bitterness of the cosmetic is reduced, and a fresh sensation, spreadability, lubricity or the like characteristic to the paste-like silicone composition can be imparted.
(FR)
Une composition d'émulsion de type huile dans l'eau produite par émulsification et dispersion d'une composition de silicone pâteuse avec et dans un ester d'acide gras de polyoxyéthylène sorbitane, l'ester d'acide gras de polyoxyéthylène sorbitane ayant un nombre de motifs oxyde d'éthylène (EO) ajoutés de 15 ou plus et un indice HLB de 11 ou plus, et la composition de silicone pâteuse étant composée d'un produit de polymérisation d'addition de polysiloxane organohydrogéné et d'un composé contenant un groupement alcényle et une huile liquide. Le composant huileux dans la composition d’émulsion de type huile dans l'eau peut être émulsifié de manière satisfaisante, et la stabilité au stockage de la composition d'émulsion de type huile dans l’eau est bonne. En outre, l'ester d'acide gras de polyoxyéthylène sorbitane est approuvé en tant qu'additif alimentaire, est peu nocif pour le corps humain, et est donc approprié aux fins de soins de la peau, en particulier pour une utilisation dans les rouges à lèvres. Par conséquent, lorsque l'ester d'acide gras de polyoxyéthylène sorbitane est ajouté à un produit cosmétique tel qu'un fond de teint ou un rouge à lèvres, l'irritation de la peau par le produit cosmétique est affaiblie, l'amertume du produit cosmétique est réduite, et une sensation fraîche, une aptitude à l'étalement, un pouvoir lubrifiant ou d’autres caractéristiques similaires peuvent être conférés à la composition de silicone pâteuse.
(JA)
エチレンオキサイド(EO)付加モル数が15以上で、HLBが11以上のポリオキシエチレンソルビタン脂肪酸エステルにより、オルガノハイドロジェンポリシロキサンとアルケニル基含有化合物との付加重合物と液状油からなるペースト状シリコーン組成物を乳化分散させた水中油型乳化組成物は、油相成分の乳化性が良好かつ保存安定性が良好であり、更にポリオキシエチレンソルビタン脂肪酸エステルは、食品添加物にも認められており、身体への害が少ないため、スキンケア用途、特に口紅用途に好適であることから、化粧水や口紅等の化粧料に配合した場合、皮膚に対する刺激性が弱く、苦みが少なく、ペースト状シリコーン組成物特有のさっぱり感、伸展性あるいは滑り性等を付与することができる。
