Description

[Detailed description of the invention]

The present invention relates to a setting lotion and a hair spray composition, and more particularly, to a hair fixing composition containing an acrylic resin as a hair fixing resin and blending a specific plasticizer with the acrylic resin, which has excellent curl holding power and which sets hair. The present invention relates to a setting lotion and hairspray composition that provides a good feel to hair. Setting lotions or hair sprays used to set waved hair generally include polyvinylpyrrolidone, polyvinylpyrrolidone-vinyl acetate copolymer, vinyl acetate-
Hair fixing resins such as crotonic acid copolymer, polyvinyl methyl ether-maleic acid half ester copolymer, carboxylated vinyl acetate copolymer, acrylic resin (alkaline, amphoteric) are dissolved in a solvent, or a propellant is further added. This composition is applied or sprayed onto the hair to form a film of the resin and fix the hair. Such setting lotions or hair sprays are required to have sufficient curl holding power as well as to give a soft and tactile finish to the hair; On the other hand, those with low strength and good curl retention have the disadvantage of giving a rough and unpleasant finish, and also rapidly lose curl retention under high humidity. Curl holding power and good feel have contradictory characteristics. For example, in primary setting such as setting lotion and hair spray, the curl holding power is largely dependent on the hydrogen bonds in the hair and the hardness of the resin film, but these hydrogen bonds in the hair do not lose their bonding strength when they meet moisture. On the other hand, from a tactile point of view, it is necessary for the resin film to contain a certain amount of water; if it does not contain any water, it will not feel "flexible".
I can't get the good feeling of "moisture". Furthermore, the hardness of the resin film impairs the feel. The above-mentioned breakage of hydrogen bonds in hair due to water is
It is said that cracks are created in the resin film due to vibrations caused by dipole-dipole interaction between the polar groups in the resin and moisture in the outside world, and water vapor passes through these cracks and reaches the hair. . Therefore, an ideal resin film for hair fixation has low water vapor permeability and the resin film itself can retain a certain amount of water. Although consideration has been given to incorporating more various plasticizers, it is difficult to select the optimal plasticizer. In particular, it has been extremely difficult to select a plasticizer for acrylic resins, which have recently been used.Up until now, plasticizers have generally been selected from liquid lanolin, lanolin derivatives such as lanolin alcohol, and aliphatic polymers such as cetyl alcohol and oleyl alcohol. Alcohols and the like have been used, but none of them can improve both the feel and curl retention. The present inventor investigated a suitable plasticizer for providing a finish with good texture in addition to excellent curl holding power in setting lotions and hair spray compositions containing such acrylic resins. If a compound with a structure in which polar groups are interspersed with a certain type of nonpolar hydrocarbon chain is used as a plasticizer, vibrations due to dipole-dipole interaction between the polar groups of the resin film and the polar groups of the plasticizer can be generated. becomes minute,
As a result, the cracks that occur in the resin film are extremely small, which not only prevents water vapor from passing through, but also traps water on the resin film due to its dipole-dipole interaction, causing vibrations between minute polar groups. As a result of repeated research on various compounds, we found that certain esters and aliphatic alcohols are extremely excellent plasticizers for providing ideal resin films. know,
The present invention has now been completed. That is, according to the research of the present inventors, a setting lotion or hair spray composition containing an acrylic resin selected from anionic acrylic resins such as acrylic acid alkyl ester-methacrylic acid alkyl ester copolymers, amphoteric acrylic resins, etc. (a) Sorbitous fatty acid ester ethylene oxide adduct having an HLB value of 13 or more (the fatty acid ester is a mono- to hexaester of a saturated or unsaturated monobasic acid having 10 to 30 carbon atoms) (b) an HLB value of 13 or more sorbitan fatty acid ester ethylene oxide adduct having (the fatty acid ester is a mono- to tetraester of a saturated or unsaturated monobasic acid having 10 to 30 carbon atoms) (c) a saturated dibasic acid having 5 to 15 carbon atoms and a saturated dibasic acid having 1 carbon number ~5
Diesters with monohydric alcohols (d) Aliphatic alcohols selected from trimethylene glycol, 2,2-dimethyl-1,3-butanediol and 3-methylpentane-1,3,5-triol are highly preferred as plasticizers. It has been found that setting lotions and hairspray compositions are available which are effective and provide excellent curl retention and a good feel finish. The above plasticizers may be blended alone or in combination of two or more, and the blending amount is usually 0.01 to 5.0% (weight%, the same hereinafter), preferably 0.05 to 0.5%, based on the total amount of the composition. be.

Agents, antioxidants, etc. may be added. Next, the present invention will be explained in more detail with reference to Examples. In addition, in the following examples, curl retention was measured as follows. After drying a bundle of hair with a length of 21 cm and a weight of 2.2 g, the temperature is 20
℃ and 70% relative humidity for 24 hours, 0.4 ml of the composition sample is applied, combed, wound into a rod, and dried with hot air at 50℃ for 30 minutes. Remove the curled hair from the rod and store at a temperature of 33℃ and relative humidity.
Hang it in a 70% box and observe how the curls grow. The length of the hair bundle immediately after placing it in the observation box is considered 100% curl retention, and the length of the original uncurled hair bundle (21cm) is considered 0% curl retention.
Curl retention is calculated according to the formula below. Curl retention (%) = L-lt/L-lo x 10
0 (In the formula, L is the length of the original uncurled hair bundle (21cm), lt is the length of the hair bundle after t (minutes), and lo is the length of the hair bundle immediately after placing it in the observation box. ).
