JP5700627B2 - Moisturizer and cosmetic or external preparation containing the same - Google Patents

Description

  The present invention relates to a humectant comprising a specific polyglycerin, and a cosmetic or an external preparation containing the same.

  In cosmetics and external preparations, polyhydric alcohols such as glycerin, propylene glycol and sorbitol are widely used as a moisture retaining agent for the human body such as skin and hair, or as a water retention agent for the product itself. However, cosmetics and external preparations containing these polyhydric alcohols may not be preferred by consumers for stickiness and sliminess when applied, and the moisturizing effect in extremely low environmental humidity. Is not effective enough, as described in Patent Document 1, a method of using a polymer moisturizer such as sodium hyaluronate, or a natural moisturizing factor such as sodium lactate or sodium pyrrolidonecarboxylate as in Patent Document 2. Improvements have been attempted by methods such as using a combination. However, none of the effects are sufficient, sodium hyaluronate is very expensive, and natural moisturizing factor is an electrolyte, so there are restrictions on blending into emulsified cosmetics due to the effect of inhibiting emulsification Thus, there has been a demand for a moisturizing agent having high moisturizing performance even under low humidity and having excellent sensory characteristics.

JP 59-209635 JP 2006-348000

  The problem to be solved by the present invention is to provide a moisturizing agent having high moisturizing performance even under low humidity and excellent sensory characteristics without stickiness or sliminess.

  As a result of intensive studies to solve the above problems, the present inventors have found that the total concentration of triglycerin and tetraglycerin is 50% by weight or more, and the concentration of each of triglycerin and tetraglycerin is 10% by weight. The present inventors have found that a moisturizing agent composed of polyglycerin in the range of% to 70% by weight has high moisturizing performance and excellent sensory characteristics, and has completed the present invention.

  That is, the present invention is based on polyglycerol in which the total concentration of triglycerin and tetraglycerin is 50% by weight or more, and the concentration of each of triglycerin and tetraglycerin is in the range of 10% by weight to 70% by weight. And a cosmetic or external preparation containing the same.

  The moisturizing agent of the present invention can provide a moisturizing agent having high moisturizing performance even under low humidity and excellent sensory characteristics without stickiness or sliminess.

  The polyhydric acid concentration of the present invention is a triglycerin concentration and a total concentration of tetraglycerin of 50% by weight or more, and each concentration of triglycerin and tetraglycerin is in the range of 10% by weight to 70% by weight. Glycerin is obtained by dehydration condensation reaction of glycerin, synthesis using glycerin-related substances such as glycidol, epichlorohydrin, glycerin halohydrin, or recovery of synthetic glycerin from glycerin distillation residue. In addition, a small amount of an alkali catalyst is added to glycerin and heated to a high temperature of 200 ° C. or higher, and polycondensation is performed while removing generated water. The reaction is a sequential intermolecular dehydration reaction to sequentially produce a high polymer, resulting in a complex mixed composition such as unreacted glycerin, diglycerin, triglycerin, and tetraglycerin. From this, unreacted glycerin and diglycerin are distilled off, or the polyglycerin is further distilled to obtain the polyglycerin having the desired composition by a method such as collecting the fraction.

  In composition analysis, about 0.5 g of a polyglycerin sample and about 0.05 g of methyl palmitate (primary reagent; Kishida Chemical) as an internal standard substance were accurately weighed, and about 1.8 ml of pyridine (special grade reagent; Kishida Chemical). It can be determined by dissolving these, then injecting 0.2 ml of TMS-HT (reagent; Tokyo Kasei Kogyo) to 20 μl of this solution, and subjecting 1 μl of the supernatant to the following analysis after the reaction in a warm bath.

Gas chromatograph: GC-14B (manufactured by Shimadzu Corporation)
Column: OV-1 (manufactured by GL Sciences, inner diameter 3 mm, length 1.5 m)
Column temperature: 100 ° C. to 350 ° C. (temperature increase rate 10 ° C./min)
Carrier gas: Nitrogen (50 ml / min)
Injection part temperature: 350 ° C
Detector temperature: 350 ° C
Detector: FID

  Hereinafter, the present invention will be described in detail.

  In the humectant comprising the specific polyglycerol of the present invention, the total of the concentration of triglycerol and the concentration of tetraglycerol is 50% by weight or more. When the sum of the triglycerin concentration and the tetraglycerin concentration is less than 50% by weight, the moisture retention under low humidity is not sufficient, and the sensory surface tends to be slimy. Moreover, it is necessary for the concentration of each of triglycerin and tetraglycerin to be 10 to 70% by weight in order to combine moisture retention and good functionality without stickiness or sliminess. The concentration of diglycerin or less is preferably 30% by weight or less, and more preferably 15% by weight or less. When the concentration of diglycerin or less is 30% by weight or less, the feeling of use is further improved, and particularly when it is 15% by weight or less, the feeling of use becomes very excellent, which is preferable. Conversely, when the concentration of polyglycerin having a high degree of polymerization such as hexaglycerin or pentaglycerin is high, the moisturizing power is improved, but the stickiness after application becomes strong.

  The moisturizing agent of the present invention is preferably contained in a cosmetic or external preparation in an amount of 0.5 to 50.0% by weight, more preferably 1.0 to 40% by weight. If it is less than 0.5% by weight, sufficient moisturizing properties cannot be exhibited. Conversely, if it exceeds 50.0% by weight, stickiness and slimy feeling are generated after coating, which is not preferable in terms of functionality.

  Cosmetics containing the moisturizer of the present invention include cleansing cream, cleansing milk, cleansing lotion, cleansing rekit, facial cleansing cream, facial cleansing foam, massage cream, cold cream, skin cream, skin gel, milky lotion, lotion, pack, beauty Skin care cosmetics such as liquid, after-shave lotion, sunscreen, body shampoo, soap, body lotion, body cream, bath preparation, hand cream and other body care cosmetics, foundation, makeup base, eye shadow, eyeliner, mascara, hoho Makeup cosmetics such as crimson, funny, eyebrow, hair shampoo, hair rinse, conditioner, treatment, hair liquid, hair tonic, hair lotion, hair cream, hair dye, hair styling etc. Hair cosmetics Also, various ointments as an external preparation, hair growth agents, dentifrice, pharmaceuticals and quasi Hinto such disinfectants can be applied regardless of the form of the product.
