The present invention relates to a novel urea group-containing organopolysiloxane and a method for manufacturing the same, as well as a cosmetic containing the same, and particularly to a cosmetic having excellent adhesion to the skin and hair, and good durability of each effect, while maintaining a feel of polysiloxane.
Organopolysiloxanes have been used in various industrial fields such as electricity, electronics, automobile, office automation equipment, medical treatment, cosmetics, food, and construction. In cosmetics, they have also been widely used in skin care, makeup, hair care cosmetics, etc., because they have features such as a light feel, good spreadability, excellent water repellency, and high safety.
Organopolysiloxanes used for cosmetics is mainly a dimethylpolysiloxane, but by modifying various organic groups, they have been used as an oil, a surfactant, a thickener, a film forming agent, a surface treatment agent for powder, etc., while maintaining properties of siloxanes.
On the other hand, urea has been used as a lotion, a moisturizing cream, etc., and also been used as a keratin care component as another use, because it has a good affinity to the skin and a moisturizing function.
A block-type polymer in which polysiloxanes are linked via a urea bond (—NHCONH—) and an application of such a polymer to cosmetics have been known in large numbers. For example, a cosmetic in which a structured polymer via a urea bond (—NHCONH—) with organopolysiloxane groups is applied to keratin material (Patent Document 1), a thickener of a block-type polymer via a urea bond by reaction of a both-terminal amino modified silicone and hexamethylene diisocyanate (patent Document 2), etc., have been known.
In addition, heretofore, there has been a demand for a cosmetic having excellent cosmetic durability due to an improvement of an affinity to the skin and hair, while maintaining a light feel, good spreadability, water repellency, which are features of silicones.
