Description

The present invention relates to a cosmetic with high molecular surfactant, more particularly, has a moisturizing effect, and relates to good skin cosmetic of the feeling. The present invention further relates to a hair cosmetic that has an excellent conditioning effect on hair and is excellent in usability.

  Usually, most skin problems are caused by the skin's loss of elasticity and moisturizing function due to a decrease in the moisture content of the skin's stratum corneum as a biologically derived barrier film due to some internal or external factor. Is. For the purpose of improving and preventing this state, conventionally, a moisturizing agent has been blended into cosmetics. Moisturizers include glycerin, ethylene glycol, propylene glycol, butylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, polypropylene glycol, sorbitol, maltitol, urea, hyaluronic acid, lactic acid or sodium lactate, amino acids, chitosan Hydrolyzed collagen, hydrolyzed wheat protein, etc. are used.

  However, when a sufficient amount of moisturizing ingredients are added to obtain a moisturizing effect, the moisturizing feeling is not sufficiently maintained, and conversely, it has a sticky feeling due to the moisturizing ingredients. It was difficult to obtain a cosmetic with a refreshing feeling.

  In addition, oily ingredients such as liquid paraffin and triglyceride blended to give emollient properties cannot improve the feeling of stickiness due to these moisturizers, and conversely increase the feeling of stickiness. For this reason, cyclic silicones with less oiliness are used as a base for cosmetics. However, the cyclic silicone has poor compatibility with other cosmetic ingredients such as a surfactant, and it has been very difficult to formulate it.

On the other hand, with regard to hair cosmetics, spreading at the time of application, passing through fingers, passing through fingers after use, and good finishing feeling after drying have become one of the important demands.
Conventionally, as hair cosmetics having a conditioning function, as disclosed in Patent Documents 1 to 3, alkyl polyalkylene glycol ethers, silicone derivatives and perfluoropolyethers have been used in hair cosmetics. A satisfactory feeling of use and finish are not obtained.

  Here, R is a hydrocarbon group having 8 to 200 carbon atoms and having 2 or more branched chains having at least 1 carbon number in the molecule. If the number of carbon atoms is less than 8, the moisture retention will decrease, and if it exceeds 200, the operability will deteriorate. As for carbon number of a branched chain, 1-3 are more preferable. Above 4 the dispersibility becomes worse. The number of branched chains is preferably 3 to 99, more preferably 5 to 55.

If it is less than 2, the hydrophilicity is inferior, and if it exceeds 100, the lipophilicity is lowered. Z is an integer of 0 or 100 or less, more preferably an integer of 0 or 50 or less.

Meanwhile, 100 g of peracetic acid prepared in advance was added at 20 ° C. or less in 1 hour. Next, 1% of the total amount of sulfuric acid was added, and after aging for 2 hours, the temperature was raised to 60 ° C. and the reaction was carried out for 10 hours. Immediately after the reaction, the mixture was cooled to 40 ° C., and the lower acetic acid aqueous solution layer was removed from the resulting mixed solution. Further, 100 g of 1% sulfuric acid aqueous solution was added, and the reaction was carried out at 95 ° C. for 10 hours. Immediately after the reaction, the mixture was cooled to 60 ° C., washed with water and neutralized, and the lower sulfuric acid aqueous solution layer was removed. Next, residual water was removed by distillation under reduced pressure.
