Abstract

PURPOSE:A stick cosmetic that is obtained by adding a hydrogenated product of yolk or vegetable-originating phospholipid to a liquid oil component, thus showing high affinity to skins or hairs and giving good feeling on application with humectant effect. CONSTITUTION:100pts.wt. of the liquid oil component selected from fluid paraffin, squallan, alpha-olefin oligomers, fluid polyisobutylene and higher fatty acid ester are 30 or more, preferably 30-400pts.wt. of hydrogenated phospholipid, which is obtained by hydrogenation of phospholipid or neutral lipid extracted from yolk or solybean and the resultant composition is used to form stick cosmetics such as lip stick, lip cream, stick foundation, stick eye shadow and so on. EFFECT:The product is free from sweating, skin irritation and toxicity.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention has a high affinity for the skin or hair, and is capable of solidifying with the addition of a small amount or no wax component, which has been conventionally used in large amounts. This is a book about new stick cosmetics that can be made.

[Conventional technology]

Currently, stick cosmetics generally use oils and fats such as cacao butter and wood wax, waxes such as carnauba wax and spermaceti wax, and hydrocarbons such as paraffin wax and microcrystalline wax as wax components.

[Problem that the invention seeks to solve]

However, stick cosmetics using these wax components tend to cause sweating, and there are problems with product stability, and it is extremely difficult to create products that have a sticky feel when used. In particular, the emergence of highly stable stick cosmetics with rich moisturizing properties is desired.

[Means for solving problems]

In view of these demands, the present inventors conducted various studies with the aim of providing a moisturizing stick cosmetic that is highly compatible with the skin or hair, has an excellent feeling of use, and found that hydrogen The present invention was completed by discovering that desired stick cosmetics can be obtained by using added phospholipids and liquid oil phase components.

That is, in the present invention, at least 3 parts by weight of a hydrogenated product of phospholipid derived from egg yolk or a plant is added to 100 parts by weight of the liquid oil phase component.
This is a stick cosmetic characterized by containing 0 parts by weight or more.

Phospholipids are substances widely distributed in the animal and plant world.1 The hydrogenated phospholipids used in the present invention are made from phospholipids extracted from egg yolks, soybeans, etc. or phospholipids containing neutral lipids as raw materials. It was hydrogenated using a conventional method. Hydrogenated phospholipids having an iodine value of 10 to 60 are used alone or in combination.

The amount of hydrogenated phospholipid added is required to be 30 parts by weight or more per 100 parts by weight of the liquid oil phase component.0 If 5 parts by weight or more of hydrogenated phospholipid is added to the acid content of the liquid oil phase, an oil gel will be formed.0 When the amount of hydrogenated phospholipid used is in the range of 5 to 30 parts by weight, it is generally gel-like, and when 30 parts by weight or more of hydrogenated phospholipid that does not take the form of a stick is used, it can be made into a snack, and it can be made into a transparent stick. You can make products. Suitable amounts ranging from 30 to 400 parts by weight are used in the practice of this invention. A wax component or gelling agent may be added to adjust the feel and hardness.

[Effect]

As the liquid oil phase component used in the present invention, hydrocarbon oils and higher fatty acid esters such as liquid halafine, squalane, α-olefin oligomers, and liquid polyisobutylene are most suitable, but animal and vegetable oils commonly used in cosmetics are suitable. Any oil can be used in combination with the hydrocarbon oil and fatty acid ester.

The stick cosmetics of the present invention can contain raw materials and additives commonly used in cosmetics.

You can also add some water. Sticky cosmetics include lipsticks, lip balms, tick foundations, tick eye shadows, and ticks.

〔Effect of the invention〕

Since the stick cosmetics of the present invention contain phospholipids, which are a type of biological component, they have excellent affinity for skin and hair and exhibit high moisturizing effects. In addition, since the hydrogenated phospholipid and oil have a gel structure, it is extremely stable and does not cause ants or sweating. In addition, there is no need to use a surfactant other than hydrogenated phospholipids, making it possible to create products that are free from skin irritation and toxicity.
