Description

Conditioning Shampoo Composition

The present invention relates to a conditioning shampoo composition, and more specifically, to non-ionic surfactants such as alkyl polyglycosides (APG), alkyl ethoxylates (AEO), monoalkyl dimethyl amine And a betaine which is an amphoteric surfactant, and does not include a sulfate-based anionic surfactant.

Shampoo, a hair cleaner, makes hair clean by removing contaminants and sebum from the hair and scalp, but the shampoo process removes the moisturizing ingredients of the sebum and hair, making the hair soft and dry, making the hair tangled and difficult to handle. In rare cases, keratin, dandruff, and inflammation may be caused by irritation by surfactants or conditioning agents included in shampoos.

In order to solve this problem, there has been a continuous study of cleaning agents or hair conditioning ingredients to improve the softness of the hair at the time of cleaning or after cleaning and to restore damaged hair. In particular, in order to protect the hair, prevent damage and impart conditioning effect to the shampoo that used to be an anionic surfactant as a main ingredient to remove the contamination of the hair and scalp in the past by emphasizing only the cleaning function, In addition to surfactants, so-called conditioning shampoos having further added a conditioning agent have been developed and put into practical use, and their use is increasing.

On the other hand, the conventional general shampoo composition is almost essentially included in the surfactant, in particular the sulfate system is often included as an anionic surfactant. Korean Patent Laid-Open Publication No. 10-2009-0056321 discloses the use of a sulfate system such as ammonium lauryl sulfate, ammonium laureth sulfate, and the Republic of Korea Patent No. 10-0845393 and the Republic of Korea Patent Publication No. 10-2010-0082931 In the arc, sulfates such as sodium lauryl sulfate are used. Such sulfate-based anionic surfactant is useful as a shampoo composition because it is very excellent in detergency and foaming power than other anionic surfactants.

However, it is a common industry opinion that such sulfate-based surfactants cause a lot of sensitized scalp due to environmental pollution and changes in lifestyle in recent years, causing irritation to these consumers. In addition, the sulfate system has a strong stimulation to promote hair damage, and has a problem of accelerating the water drainage (color loss) of hair (dyed hair), especially dyed hair with excessive cleaning power.

Therefore, the present inventors have a conditioner shampoo composition which is excellent in the feeling by providing a softness to the hair even when rinsing, while having a low irritation to the skin and scalp without using a conventional surfactant-based surfactant, and having a softness to the hair even during rinsing. By developing, this invention was completed.

Republic of Korea Patent Publication No. 10-2009-0056321 Republic of Korea Patent No. 10-0845393 Republic of Korea Patent Publication No. 10-2010-0082931

Therefore, in order to solve the above-mentioned problems, the present invention does not use the conventional sulfate-based surfactants, and has less irritation to the skin and scalp, but also has excellent cleaning power and foaming power, which is a function of the shampoo, and softens the hair even when rinsing. It is intended to provide a shampoo composition excellent in feeling.

First, definitions of terms used in the present invention are as follows.

The term "surfactant" of the present invention refers to a compound having a hydrophilic portion that is soluble in water and a hydrophobic portion that is soluble in oil.

Surfactants gather together to form a structure called micelles at or above a certain concentration. These micelles have a surfactant concentration above the critical micelle concentration and a critical micelle temperature. Or Kraft temperature). When micelles are formed in water, the hydrophobic portion of the surfactant gathers at the center to form a nucleus and the hydrophilic portion forms an outer portion in contact with water. Like oil, hydrophobic substances are located in the inner part of micelles, so they are stabilized and dissolved in water. This is called solubilization and is the basic principle of cleaning.

Types of surfactants are classified into ionic and nonionic surfactants depending on whether they are dissociated and ionized in aqueous solution. In the case of ionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants are classified in detail. Classified as

In other words, the term "nonionic surfactant" of the present invention means that the hydrophilic portion has a non-electrolyte, i.e., a hydrophilic portion that does not ionize, for example, a low molecular type such as alkyl glycol or a polymer based such as polyethylene glycol and polyvinyl alcohol. And fatty acid systems.

In addition, "amphoteric surfactant" refers to a surfactant which, when dissociated in an aqueous solution, has both anionic sites and cationizable sites in a molecule, and thus may be cations or anions depending on the pH of the solution.
