Description

[Detailed description of the invention] production I side rule t1 The present invention relates to a cleaning composition for puffs.

PRIOR ART Puffs are used to apply foundation. Puffs are relatively expensive and are typically washed and used repeatedly. Soap or household liquid detergents are generally used for cleaning, but puffs that are stained with oil-based foundations become clogged with pigment and are difficult to remove, and are eventually thrown away due to cosmetic reasons. This tendency is common in NBR-based puffs and cross-linked PVA-based puffs.

At present, no cleaning agent specifically designed for this puff has been developed.

Problems to be Solved by the Invention The object of the present invention is to develop a cleaning composition that can easily remove stains from foundation puffs.

The present invention has been applied to various detergents that have been known to have high cleaning power, such as kitchen detergents, laundry detergents, toilets, furniture,

It became clear on January 11 that it had almost no effect. .

Although the present inventors have conducted extensive research on a huge number of surfactants, they have found that certain nonionic surfactants +11: It has been found that by using the agent, dirt on the puff, which was thought to be impossible, can be removed extremely easily and almost completely.

That is, the present invention relates to a detergent composition for puffs comprising a non-ionic 11.1111 activator with a weight of 11 L B 8 to 1/I.

In the present invention, the nonionic surfactant has an average II 1

B 1 (Even if you obtain 1, l: What does it mean? In the present invention, active agents other than nonionic surfactants,
For example, anionic surfactants, cationic surfactants, and amphoteric surfactants are not preferred. They cannot be used in combination with nonionic surfactants to obtain better results, and Among the ionic surfactants, particularly preferred are polyoxyethylene alkyl ethers or polyoxyethylene alkylaryl ethers. Examples of polyoxyethylene alkyl ethers include natural alcohols, synthetic alcohols (Tigra alcohol, oxo alcohol, modified alcohols), and polyoxyethylene alkyl ethers. Ethylene oxide adducts of secondary alcohols, etc.) are preferred, and these alcohols may have side chains or straight chains, but in particular higher alcohols with side chains, secondary alcohols derived from secondary alcohols, etc. are preferred. Excellent effects can be obtained using polyoxyethylene alkyl ethers.

Good results are obtained when the alkyl group is saturated and has 8 to 20 carbon atoms, particularly 12 to 14 carbon atoms.

When using a secondary CI2 to C14 alcohol, particularly good results are obtained when the number of moles of ethyl oxide added is in the range of 4 to 8.

A second example that is particularly preferred in the present invention is a polyoxyethylene alkylaryl ether type nonionic surfactant, and particularly good results are obtained in the ethylene oxide (11-adduct) of nonylphenol.

The appropriate number of moles of ethylene oxide added is 4 to 8 moles.

Examples of the nonionic surfactants used in the present invention are esters of polyethylene glycol (hereinafter referred to as PEG) and higher fatty acids, sorbitan alkylate, or ethylene oxide adducts thereof. Examples of esters of PEG and higher fatty acids include PEG (average molecular weight 20 ('
1 ) and oleic acid, etc. These esters do not necessarily have a sufficient cleaning effect compared to the alkyl ethers and alkylphenyl ethers, but
It may be used in combination with alkyl ethers and alkylphenyl ethers since it does not cause rough hands.

Preferred nonionic surfactants include fatty acid diethanolamyl S' type surfactants. Particularly good results are obtained with □ coconut oil fatty acid noethanolamide (1:1 type). Fatty acid noethanolamide type surfactants are mild to the skin, and may be used in combination with other surfactants.

In the cleaning agent for puffs of the present invention, the nonionic surfactant described in "2" may be used alone. 100% nonionic surfactants usually become gel-like when mixed with water, making them difficult to use.
It is diluted with water to 50% or less in advance, or its solubility is adjusted with a suitable solvent such as ethanol, glycerin, alkylene glycol, cellosolve, etc. Particularly preferred solvents are:
These are ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, propylene glycol, and tripropylene glycol. Of course other suitable additives, e.g. cleaning aids (bilgu)
, dyes, fragrances, preservatives, fungicides, antibacterial agents, etc. may be added.

The cleaning agent of the present invention can also be used to clean puffs used for emulsion-type foundations, cake-type foundations, etc.11, but these can be relatively easily cleaned with ordinary detergents. υ]': Therefore, the cleaning agent of the present invention is particularly suitable for cleaning oil+'l foundation.

Effects of the Invention 1: By using the puff cleaning agent of the present invention, puffs that could not be sufficiently cleaned with conventional household detergents, soaps, etc. can be cleaned very easily and almost completely.

The present invention will be explained with reference to 13 examples.
