Description

Technical Field

[0001] The present invention relates to an emulsified cosmetic having an almighty feeling of use (feeling of elongation, non-stickiness, and stickiness) that can be used on hair and skin, sufficient safety, and improved dischargeability when pressed from a pump.

Background Art

[0002] Among the cosmetic preparations provided to consumers, there are many preparations designated for each part of the human body, such as for hair, body, face, oral cavity, hands and feet. This is of course because the functions required for each are different, and the desired feeling of use and safety are different.

[0003] However, in recent years, almighty preparations considering time saving, ease of use, environmental conservation purposes, etc. have attracted attention. For example, all-purpose shampoos, all-purpose body soaps, all-purpose creams, oils that can be used not only on hair but also on nails and hands and feet. In addition, cosmetics having multi-functions such as preparations that can be provided for various damages other than the body part to be used and preparations that can be used regardless of age and gender are also one of the examples.

[0004] Among these, in particular, preparations that can be used by anyone, adults or children, are considered to have the most important issue of safety, and the development of preparations for children and babies is particularly eye-catching.

In addition, other substances known as substitutes that are not originally derived from animals, such as plant-derived "white liquids" like soy milk, gruel (rice milk), almond milk, coconut milk, and cocoa milk, can also be cited as examples and can be preferably used. Component (D) is formulated for the purpose of providing a good feeling in use. and blended.

[0024] The milk-derived component of component (D) of the present invention is not particularly limited, but may be selected from a group of components obtained by processing processes such as raw, refined, frozen, dried, fermented, heated, coagulated, defatted, extracted, concentrated, aged, added, hydrolyzed, etc., and one or more thereof can be used in combination. The blending amount is not particularly limited as long as the effects of the present invention are exhibited, but is preferably 0.001 to 5% by mass, more preferably 0.01 to 1% by mass. Within this range, a good feeling in use such as elongation and non-stickiness can be expected.

[0025] The milk-derived component of component (D) of the present invention is not particularly limited, but specific examples thereof include milk, lactose, lactic acid, whey, lactoferrin, yogurt liquid, casein, fresh cream, skim milk powder, skim milk, condensed milk, cheese, milk fat, and butter. It is preferably selected from these, and also includes plant-derived milk substitutes such as soy milk, almond milk, oat milk, cashew milk, hemp milk, pea milk, flax milk, amazake, congee (rice milk), coconut milk, and cocoa milk, and / or extracts, juices, oils, powders, extracts, etc. of the plants from which they are derived, and can be preferably used.

[0030] In the present invention, it is preferable not to contain a cationic surfactant. Another name, a cationic surfactant, is a surfactant that dissociates into ions in its aqueous solution and the atomic group showing surface activity becomes a cation. Cationic surfactants include alkylamine salt types such as monoalkylamine salts, dialkylamine salts, and trialkylamine salts, and quaternary ammonium salt types such as alkyltrimethylammonium chloride, dialkyldimethylammonium chloride, and alkylbenzalkonium chloride, and are mainly components widely used in applications such as dispersants, emulsifiers, bactericides, softeners, hair rinse bases, and antistatic agents. However, it is considered to have mild toxicity and there are concerns about its irritancy. Therefore, conventionally, cationic surfactants have been widely used for the purpose of achieving excellent usability and conditioning effects on hair in hair cosmetics. On the other hand, in terms of safety, it has been undesirable in cosmetics used on the skin. In the present invention, by blending specific components in a specific ratio, it is possible to be used for children, adults, skin, and hair without the concern of a decrease in the usability even without using a cationic surfactant.

Although not particularly limited, in the emulsified cosmetic of the present invention, the pump-type container preferably has a discharge amount per time of 0.3 to 1.0 cc. More preferably, it is 0.3 to 0.7 cc. Within this range, in the emulsified cosmetic of the present invention, from children to adults, it is suitable from the viewpoint of dischargeability when pressing, corresponding to all-mighty users.

[0034] Furthermore, within a range that does not impair the effects of the present invention, other additional components commonly used in cosmetics, etc. can be blended as necessary. As these additional components, for example, amino acids, extract extracts, antibacterial agents, ultraviolet absorbers, antioxidants, vitamins, touch modifiers, fats and oils, vegetable oils, fragrances, surfactants, thickeners, etc. can be blended.
