Description

Hair styling composition containing new wax-polymer

The present invention relates to a styling agent composition, and more particularly, to contain a novel wax polymer to enable re-styling in a polymer resin type styling agent such as spray, mousse, gel, etc. It relates to a styling agent composition to impart and to improve the sustaining style styling agents such as wax.

In general, the main function of the hair is first, the body protection function. Hair protects the body from external mechanical and chemical stimuli. That is, it prevents the ingress of harmful substances and protects the human body from external stimuli such as cold, friction, and direct sunlight. Second, it has a cosmetic effect of decorating the appearance as a decorative function. This is an important role in the characterization of women and men. Third, it functions to transmit tactile sensations or pains as perceptual functions.

Among them, decorative function has been important from the ancient point of view of cosmetic effects, and recently, with the advent of perm and dyeing procedure, it has been spotlighted as a means of expressing personality in various ways. In addition, cosmetics used to temporarily form a hair style and to sustain the hair style are styling agent compositions, and examples thereof include hairspray, mousse, gel, and wax. Such styling composition should have good persistence to maintain desired hair shape for a long time, be convenient when using without stickiness, easy to clean, and give proper gloss and softness to hair. There will be.

The method for fixing and setting the hair of the styling agent composition includes a type using a semisolid or viscous fat or oil component at room temperature, a type using a polymer resin, and a type using a moisturizer. In recent years, the amount of hair wax that has increased in use has high melting point maintenance ingredients (carnauba wax, candelilla wax, microcrystalline wax, beeswax, paraffin wax, etc.) to form a film on the surface of the hair to give a fixing force. These oils and fats keep the hair natural and supple and allow for restyling. However, most of the conventional waxes used in hair wax have high stickiness, and there is a disadvantage that the hairs may be aggregated and greasy due to poor spreadability in the hands and hair, and also poor cleaning power.

Next, styling agents using polymer resins include hair sprays, hair mousses, and hair gels, and polymers such as pyrrolidone, acrylic acid, and acrylates may be used alone or in the form of copolymers thereof. After evaporation, it adheres to the hair through the formation of a film, which creates a holding force on the hair to create the desired style. These styling agents have the advantage of excellent setting power, excellent applicability to hands and hair and good cleaning compared to hair wax. However, there is a disadvantage that a hard film is formed, which may cause flaking phenomenon or the style may look unnatural, and restyling is difficult.

Accordingly, the present inventors have tried to develop a styling composition capable of restyling while having excellent setting power and cleaning power. When applied to the polymer resin type styling agent was found to be able to restyling and give a natural feeling, such as wax, and also found that the style sustainability is improved when applied to the maintenance type styling agent and completed the present invention.
