Description

Aerosol Hair Spray Composition

The present invention relates to an aerosol hair spray composition having a good set hold under high humidity when used with a propellant as a spray composition prepared using a mixture of amphoteric and anionic resins.

Aerosol hairspray compositions must have several functional requirements, starting with the human desire to maintain a beautiful hair shape for a period of time. Among these requirements, the film retains its beautiful shape even under high humidity, has good combing properties when combing, and does not cause powdering or flaking of the film, and must be completely removed when cleaning with shampoo or the like. In addition, the aerosol hairspray composition has a beautiful shape and has good spreadability along the hair when applied to the hair to form a transparent film, so that bead-like powder (beading) does not occur during drying.

The butyl ester PVM / MA carrier, commercially available under the trade name Gantrez A-425, an anionic resin, has a low settability under high humidity, but has a good combing property when combing, It has the advantage that no flaking occurs.

Therefore, an object of the present invention is a composition using a mixture of amphoteric and anionic resins of acrylic type suitable for alcohols having improved storage and styling properties under high humidity, and when applied to the hair through a dispenser, good bead-like powder occurs. The present invention provides an aerosol hairspray composition having good combability during combing, no powdering or flaking of the film, and excellent washing property when washed.

The present invention has a weight average molecular weight of 50,000 or more, glass transition temperature of 50 ℃ or more of acrylic and vinyl type amphoteric or anionic resin 1.0% by weight-8.0% by weight, mass average molecular weight of 50,000 or less and glass transition temperature of 50 ℃ or less 0.1 wt% -3.0 wt% of anionic resin, 0.1 wt% -3.0 wt% of anionic resin having a mass average molecular weight of 50,000 or less and glass transition temperature of 50 ° C. or less, 0.1 wt% of an aqueous hydroxypropyl chitosan solution having a mass average molecular weight of 800,000 5.0 wt%, 0.05 wt% -3.0 wt% of resin neutralizing agent, 0.01 wt% -2.0 wt% of organic acid dissolved in alcohol, 5.0 wt% -50 wt% of propellant and the remainder are directed to aerosol hair treatment compositions consisting of ethanol. One or two or more acrylic resins and vinyl resins selected from copolymers and vinyl acetate / butyl maleate / isobornyl acrylate copolymers are suitable. . The resin used has a high mass average molecular weight, high glass transition temperature, and when applied to the hair, the adhesiveness and stiffness of the film is increased, resulting in high curl retention. Excellent ability to show the three fixed head fixed. Particularly effective resins in the present invention include octylacrylamide / acrylate / butylaminoethyl / methacrylate copolymers commercially available from National Starch Trade Name Ampomers having a glass transition temperature of 100 ° C. or higher and a mass average molecular weight of 50,000 or higher. It is advantageous. It is preferable to use 1.0 to 8.0% by weight of the amphoteric or anionic resin of acryl and vinyl system. If the resin is used at 1.0 wt% or less, desirable set fixing properties cannot be achieved. If 8.0 wt% or more is used, severe powdering or flaking occurs in the film, and the spray particles become large during spraying, causing particle dropping and valve clogging. Phenomenon develops and spreads, and can cause severe bead-like white powder. It has the advantage of not powdering or flaking. Therefore, when used in combination with the above-mentioned acrylic and vinyl-based amphoteric or anionic resins, it not only increases the set fixability of the aerosol hairspray composition but also has good combing property when applied to the hair. It has the advantage of reducing the occurrence of powdered or flaky of the acrylic resin film. Particularly effective in the present invention is a butyl ester PVM / MA copolymer sold under the trade name Gatrez A-425 of ISP Corporation having a glass transition temperature of 50 ° C. or lower and a mass average molecular weight of 50,000 or lower. It is preferable to use 0.1 to 3.0% by weight of such anionic resin. When the anionic resin is used in an amount of 0.1% by weight or less, the above-described desirable properties are not exhibited. When the anionic resin is used in an amount of 3.0% by weight or more, the settability is increased, but accompanying may cause powdering or flaking of the film. It is used a lot. The above-mentioned neutralizing agents may be used alone or in a mixture of two or more kinds. The neutralizing agent used in the resin generally uses a neutralization rate of 90% or more because it is one of the main factors causing the strength of the film, the washability during washing, and the differentiation or flaking of the film. The ratio of acid or salicylic acid is 5: 1. The resin solution is preferably mixed and completely dissolved by adding an organic acid, HPCH liquid, DC-244 and other components and corrected with ethanol. Thereafter, the above composition was put in a can and filled with LPI to prepare an aerosol hairspray.

Curling retention is applied to a fixed amount of aerosol hairspray composition to 28cm, 0.5g test hair, and then wound in Spiral and dried at 60 ° C for 30 minutes or 25 ° C room temperature for 2 hours. After removing the test hair from the spiral, the curled test hair is placed in a constant temperature and humidity chamber at 25 ° C. and 90% RH to measure the curl tension. Curl Retention (%) = (Lo-Lt) * 100. Here, Lo is the length of the test hair, Ls is the length of the first test hair curled (t = 0), and Lt is the length of the test hair curled after t hours.
