Problems solved by technology

However, the specific ester compound ((behenic acid / eicosanedioic acid) glyceride) shown in the examples is not in the form of a water-in-oil emulsion and has high moisture retention only in the oil phase, but External skin preparations containing the above-mentioned ester compound cannot satisfy the spreadability on the skin and storage stability due to the formation of a hard composition

Embodiment

[0115] Hereinafter, the present invention will be described in more detail by showing examples and comparative examples of the present invention, but the present invention is not limited to these examples. In addition, hereinafter, unless otherwise stated, "%" means "% (mass)".

[0116] Synthesis example 1~3 (poly 12-hydroxystearic acid)

Synthetic example 1

[0118] 500 g of 12-hydroxystearic acid (manufactured by Kawaken Fine Chemicals Co., Ltd., trade name: hydroxystearic acid) was added to a 1 L four-necked flask equipped with a stirrer, a thermometer, a nitrogen blowing tube, and a moisture separator, and 0.5 g of tin chloride as a catalyst was reacted at a temperature of 200° C. for 15 hours while removing generated water under a nitrogen stream. After the reaction was completed, the catalyst was removed by filtration, followed by decolorization using activated carbon, and deodorization was performed by blowing water vapor under reduced pressure. The acid value of the obtained polymer was measured, and as a result, poly-12-hydroxystearic acid of Synthesis Example 1 was obtained with an acid value of 33 mgKOH / g, an average molecular weight calculated from the acid value of 1700, and an average degree of polymerization calculated from the average molecular weight of 6. (yield 430g).

Synthetic example 2

[0120] 500 g of 12-hydroxystearic acid HP (manufactured by Kokura Gosei Co., Ltd., trade name: 12-hydrogen acid HP) was added to a 1 L four-necked flask equipped with a stirrer, a thermometer, a nitrogen blowing tube, and a moisture separator, and With 0.1% of tin chloride as a catalyst, the reaction was carried out at a temperature of 200° C. for 15 hours while removing generated water under a nitrogen stream. After the reaction was completed, the catalyst was removed by filtration, followed by decolorization using activated carbon, and deodorization was performed by blowing water vapor under reduced pressure. The acid value of the obtained polymer was measured, and as a result, poly-12-hydroxystearic acid of Synthesis Example 2 was obtained with an acid value of 20 mgKOH / g, an average molecular weight calculated from the acid value of 2820, and an average degree of polymerization calculated from the average molecular weight of 10. (yield 410g).

Abstract

Disclosed is a vaseline-like composition which contains 5 to 20 mass% of one or more components selected from components (C), (D), and (E), 40 to 90 mass% of component (A), and 5 to 50 mass% of component (B). Also disclosed is a cosmetic preparation which contains said vaseline-like composition. [Component (A) represents one or more ester compounds selected from diisostearyl malate and diglyceryl triisostearate; component (B) represents a hydrocarbon wax having a melting point of 70 to 130 DEG C; component (C) represents a poly-12-hydroxystearate having an average polymerization degree of 3 to 20; component (D) represents a poly-12-hydroxystearate derivative obtained by esterifying a poly-12-hydroxystearate having an average polymerization degree of 3 to 20 with a polyhydric alcohol having a valency of 5 or more; and component (E) represents a dimer dilinoleate derivative.] As a consequence, it is possible to provide a vaseline-like composition which achieves moisture retaining properties equivalent to that of vaseline, exerts excellent spreadability and conformity to the skin, and is not sticky. Additionally, provided is a cosmetic preparation combined with said composition.

Description

technical field [0001] The present invention relates to a petroleum jelly-like composition having moisturizing properties equivalent to petroleum jelly, excellent spreadability on the skin, low stickiness (ベたつき) and good skin compliance, and cosmetics containing the composition . [0002] This application claims priority based on Japanese Patent Application No. 2010-070136 for which it applied in Japan on March 25, 2010, and uses the content here. Background technique [0003] Petroleum jelly is obtained by refining the ointment substance obtained by solvent dewaxing the vacuum distillation residue of crude oil, and its main component is C24~C34 hydrocarbons and is amorphous. As a highly refined substance, white vaseline that can be used in cosmetics and pharmaceuticals is commercially available. [0004] Vaseline is often used in cosmetics for skin care, cosmetics for makeup, and pharmaceuticals for external use on the skin. Its most important functions are moisture rete...
