Description

  The present invention relates to a rinsing hair cosmetic suitable for rinsing, conditioner, treatment, hair essence and the like.

  The 1-hydroxy-2-pyridone compound is a component having a dandruff / itch prevention effect, and is blended in hair cosmetics. However, a rinsing hair cosmetic prepared by blending a 1-hydroxy-2-pyridone compound with a rinsing hair cosmetic containing a cationic surfactant and a long-chain aliphatic alcohol is used as an olefin resin (polyethylene (PE)). When a plastic container using polypropylene (PP) was filled, the 1-hydroxy-2-pyridone compound was adsorbed on the container, and the stability of the rinse hair cosmetic could not be secured.

  From the above, as a rinse hair cosmetic container containing the 1-hydroxy-2-pyridone compound, a polyethylene terephthalate resin (PET) that suppresses the adsorption of the 1-hydroxy-2-pyridone compound is used. The container used was used. However, since polyethylene terephthalate resin (PET) is difficult to process tubes, films, etc., compared to olefin resins (PE, PP), containers using a dispenser having a fine structure, containers such as tube types, etc. It was not possible to apply to the system, and the restrictions on the usage pattern were large. From the above, there has been a demand for a technique for suppressing adsorption of a 1-hydroxy-2-pyridone compound when a container using an inexpensive and easily processable olefin resin (PE, PP) is filled. (See Patent Document 1: JP 2001-354514 A). Moreover, in order to exhibit the effect, the rinse-type hair cosmetics are required to be spread evenly on the surface of the hair, and have been desired to be easily stretched and difficult to foam.

Residual rate (%) = quantitative value of component (B) after storage at 40 ° C. for 6 months / quantitative value of component (B) at the beginning of preparation × 100

Liquid Chromatography Conditions Ultraviolet absorptiometer: measurement wavelength: 300 nm, column: inner diameter 4.6 mm, length 25 cm stainless tube filled with 5 μm octadecylsilylated silica gel for liquid chromatography. Guard column: A stainless tube having an inner diameter of 4.0 mm and a length of 10 mm was filled with octadecylsilylated silica gel for liquid chromatography of 5 μm.
Column temperature 40 ° C., mobile phase: methanol / water / ethylenediaminetetraacetic acid disodium dihydrogen acetate dihydrate 0.25% aqueous solution / phosphoric acid mixture = 40: 8: 1: 1 (volume ratio), detector: HITACHI L -7405H

<Stability of composition: presence or absence of separation>
The separation after storage at 40 ° C. for 6 months was visually observed. Those with no separation were marked with “◯”, and those with separation were marked with “x”.

<Easy to stretch and no foaming>
Evaluations were made on “ease of stretching” and “non-foaming” when applying a conditioner to hair. Evaluation was performed by 10 test subjects, and the number of people judged “good” was shown according to the following evaluation criteria.
[Evaluation criteria]
"Easy to stretch"
◎: 9 to 10 subjects who answered good ○: 7 to 8 subjects who answered good Δ: 4 to 6 subjects who answered good ×: 0 to 3 subjects who answered “good” Noness "
◎: 10 subjects who answered that they did not feel bubbling ○: 8-9 subjects who answered that they did not feel bubbling Δ: 6-7 subjects who answered that they did not feel bubbling ×: 0 to 5 subjects responding
