Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a novel cleaning composition, and more specifically, it has high cleaning properties against makeup stains such as mouth C and foundation, and sebum stains, and The present invention relates to a cleansing composition for body cleansing that is hypoallergenic to the skin and hair.

(Conventional technology) Conventionally, makeup stains from lipstick, foundation, eye shadow, makeup stains, etc. contain large amounts of oil or solid oils, and with ordinary soap-based facial cleansing foams, Make-up stains cannot be removed due to insufficient solubility and emulsifying ability. Therefore, make-up stains should be removed using cleansing creams, cleansing oils, or gel-like microwave removers based on oil bases. was.

On the other hand, when dirt such as fat and keratin proteins get into the pores of the skin and solidify, as in the case of acne, causing inflammation within the hair follicle, commonly used facial cleansers do not remove the solid dirt that clogs the pores. The cleaning properties are not sufficient to remove the
Combination use of keratolytic agents such as salicylic acid and sulfur is widely practiced.

[Problem to be solved by the invention]

As mentioned above, in order to remove solid oils such as make-up and sebum, as well as strong oily stains, ordinary facial cleansers based on fatty acid soaps, anions, and nonionic active agents do not have sufficient cleaning properties. Cleansing creams that are mainly oil-based have the disadvantage that when used in hot and humid places such as bathrooms, the emulsification state deteriorates due to the inclusion of water and components, making it difficult to remove stains or causing them to separate. had.

[Means to solve the problem]

The present inventors have solved the above problem (as a result of intensive research,
By combining a 4-rated nonionic active agent and a phosphate ester surfactant, it has high cleaning properties against oily stains, is less irritating to the skin, and foams with good stability even in humid areas. The present inventors have discovered that a cleansing composition can be obtained, and have completed the present invention.

That is, the present invention is based on (A) general formula (I) % formula % (I) (wherein R represents a branched saturated or unsaturated hydrocarbon group having 4 to 30 carbon atoms, and X represents O to 30, y is 0-3
represents an integer of 0, provided that x+y≧ and HL

(II)x (wherein Rt, Rs and R4 each have 8 to 1 carbon atoms
8 represents a linear or branched alkyl group or alkenyl group, X and Y each represent a hydrogen atom, an alkali metal, ammonium, or an alkanolamine having a hydroxyalkyl group having 2 to 3 carbon atoms, l, - and n each represents a number from 0 to 10.

The nonionic activator represented by the general formula (I), which is the component (^) of the present invention, must have a B value of 3 or more and less than 8, and a branched chain.

For IILB, the value given by the following formula determined from the organic and inorganic properties of Koen and Teramura et al. was adopted here.

In the present invention, if the nonionic active agent has a B value of less than 3, its hydrophobicity is too strong and it becomes an oil component, resulting in significantly poor foaming properties. Moreover, when the HLB of the nonionic activator is 8 or more,
It has high hydrophilicity and has poor cleaning and emulsifying properties for oil-based makeup stains.

Therefore, the IILB of the nonionic activator is preferably 3 or more and less than 8, particularly preferably HLB 6 to 7.5.

Furthermore, even if the nonionic activator falls within this range of IILB value, those with linear hydrocarbon groups have insufficient cleaning properties and are not suitable for the present invention, which aims to remove oily stains. .

In the compound represented by the above general formula (I) which is the component (A) of the present invention, R+ is a branched saturated or unsaturated hydrocarbon group having 4 to 30 carbon atoms; Alkyl groups are preferred. In particular, a branched secondary alkyl group having 8 to 20 carbon atoms or a branched alkyl group selected from the following: 2-ethylhexyl, 2-ethyloctyl, 2-ethyldecyl, 2-ethyldodecyl, 2-
