Description

  The present invention relates to a cosmetic containing an organopolysiloxane compound as an active ingredient.

  In recent years, organopolysiloxane compounds such as silicone oils and silicone resins are generally oily, have excellent water repellency, lubricity, and gloss imparting properties, and have a smoother feel, such as hair cosmetics and skin cosmetics. Used in various cosmetics. For example, to improve the water repellency of cosmetics such as skin creams and skin lotions that have been used to protect the skin from rough skin, silicone oils and silicone resins have been added to improve makeup. These formulations form a barrier on the skin, prevent the loss of water-soluble components and sebum in the skin due to sweating and water work, and give the skin flexibility by the action of moisturizers and water-soluble components. By protecting the skin. In recent years, these creams and lotions have been required to last long enough to eliminate the work that has been lost on the skin due to water work or sweating and must be repainted. Things have been done.

  Further, makeup cosmetics such as foundations and lipsticks are blended with silicone oil or silicone resin in order to improve the problem of makeup collapse over time and the makeup cosmetics adhering to clothes, cups and the like. In hair cosmetics such as hair mousse and hair spray, hair is set with a set resin. However, there is a demand for a hair setting effect that does not drop even under high humidity and that maintains the hair setting effect. In other words, silicone oil or silicone resin is blended.

  However, organopolysiloxane compounds have advantageous properties as described above, but on the other hand, stickiness occurs when the amount added to cosmetics increases, and organopolysiloxane compounds have low compatibility with other cosmetic ingredients. Cosmetics containing a polysiloxane compound, for example, oil-in-water (hereinafter referred to as “O / W type”) emulsion cosmetics or water-in-oil (hereinafter referred to as “W / O type”) emulsion cosmetics, The emulsion stabilization and suspension dispersion stability of organopolysiloxane compounds in turbid dispersion type cosmetics may be insufficient, which may cause stickiness of cosmetics, and coatings formed from organopolysiloxane compounds may become polar solvents. There was a problem that the application range was limited due to poor re-solubility.

  In order to solve these problems, various methods have been proposed. For example, there is a method using a copolymer obtained by radical polymerization of an organopolysiloxane compound with a vinyl compound such as vinyl pyrrolidone, acrylate, or methacrylate (see, for example, Patent Documents 1 to 5). However, this copolymer was still unsatisfactory due to insufficient dispersion stability of the organopolysiloxane compound.

  On the other hand, a method in which a polysaccharide compound is silylated or siliconeized has been proposed. For example, cosmetics containing a polysaccharide compound having a triorganosilyl group (for example, see Patent Document 6) and cosmetics containing a polysaccharide compound having an organopolysiloxane group (for example, see Patent Documents 7 and 8) are disclosed. . However, the dispersion stability of the organopolysiloxane compound is still not sufficiently improved. As a result, the silicone-like feel is poor, there is a sticky feel, and the water resistance and secondary adhesion are not sufficient. There was no satisfactory effect, and there was a strong demand for improvement.

In the case of Alkaligenes Reuterus B-16 strain bacteria, it is produced as follows. Alkaline Genus rutas B-16 strain bacteria are cultivated by the usual microorganism culture method, for example, monosaccharides such as fructose, glucose and sucrose as a carbon source, natural polymers such as hemicellulose, starch and corn starch, olive oil and the like Oils, nitrogen sources such as urea, ammonium chloride, ammonium nitrate, ammonium sulfate and other inorganic nitrogen sources, tryptone, yeast extract, meat extract, peptone, malt extract and other organic nitrogen sources, other potassium phosphate, magnesium sulfate, Using a medium supplemented with inorganic salts such as sodium chloride, aeration and stirring liquid culture is performed for 3 to 10 days at an initial pH of 4 to 10 and a culture temperature of 15 to 40 ° C. After culturing, an organic solvent such as acetone, ethanol, isopropyl alcohol or the like that is about twice (volume) or more is added to the culture solution, and the culture product is recovered as an insoluble aggregate.

It has been confirmed that at least two types of polysaccharides are contained in the polysaccharides produced by Alkaline Generus B-16 strain bacteria (hereinafter referred to as “B-16 polysaccharides”). It is a polysaccharide having a structure in which one fucose is branched to one glucose in the main chain of a repeating structure composed of glucose, glucuronic acid, and rhamnose as shown in the formula (1), and its molecular weight is about 10 ⁹ It is a high molecular component [see the abstract of the 1998 Annual Meeting of the Agricultural Chemical Society of Japan, page 371]. The other is a polysaccharide having a repeating structure substantially composed of fucose and mannose, and is a low molecular component having a molecular weight of 10 ³ to 10 ⁷ [Y.

  In the organosilicon-containing polysaccharide obtained by reacting the component (B) and the component (C), it is not necessary to react all the hydroxyl groups in the polysaccharide of the component (B) with the component (C). ) 0.1 to 2.5 moles of an average content hydroxyl group (usually 2 to 3 hydroxyl groups / 1 constituent monosaccharide) of the constituent monosaccharide in one unit of the repeating structure of the polysaccharide component [degree of substitution 0. 1-2.5] may have reacted with the component (C).

  The mixing ratio at the time of the reaction between the component (B) and the component (C) may be appropriately determined in consideration of the degree of hydrophobicity of the target organosilicon-containing polysaccharide and the affinity with the component (A). Although it cannot be determined uniformly, the component (C) may be usually blended in the range of 5 to 50% by weight with respect to the component (B).
