Description

Personal Cleansing Composition for Damage Prevention}

The present invention relates to a cleaning composition, and specifically, a coacervate having a fine and uniform particle distribution in a cleaning process by including a surfactant and a cationic polymer having two hydrophilic anionic moieties in one molecule upon dissociation in water It relates to a detergent composition that provides an effect of preventing damage to the surface of a substrate (hair, skin, fiber) in the cleaning process by forming a.

Detergents such as shampoo, body wash, and laundry detergent include anionic or amphoteric surfactants for cleansing and foaming; and cationic polymers for conditioning, stabilizing, increasing viscosity, controlling foam, and depositing other conditioning materials.

Anionic / amphoteric surfactants and cationic polymers coexisting in the form of mixed micelles or structured micelles in the detergent are diluted by water generated during the cleaning process, so that cationic polymers and anionic surfactants form ions in a specific composition. It is known to form a complex coacervate formed by combining, and this phase separation phenomenon is known as coacervation.

Coacervation plays a very important role in hair conditioning, especially when the hair is wet during the shampooing process and during the rinsing process. The formed coacervate is effectively deposited on the hair surface and provides various benefits to the hair.

Most conditioning shampoos rely on polymer-surfactant coacervate deposition properties to impart combability and manageability when wet. Coacervates are also associated with the dry feeling of shampoo by forming a thin film on the surface of the hair containing insoluble active ingredients dispersed in the shampoo. The coacervate forms a co-aggregate with substances suspended in the shampoo solution during the rinsing process, and the formed aggregate is deposited on the surface of the hair.

When the hair is dry, the surface of the hair is coated with a thin film of polymer-surfactant coacervate and insoluble active ingredients such as oil and silicone, which are present in a dispersed state in the shampoo. Therefore, the coated coacervate forms a coating on the outermost surface of the hair after shampooing, and acts as an important factor in determining the tactile feeling in the hand that consumers feel emotionally when they touch the hair, thereby making the shampoo moist or dry. It also plays a very important role in determining feelings.

It is widely known that human hair is damaged by various factors, such as chemical factors such as perm and dyeing, including natural aging, and physical factors such as UV, heat, and combing. Hair is also known to be damaged by surfactants and the like included in shampoos in a daily washing process. In this regard, Rita de Cassia Comis Wagner et al. found that a 5% sodium lauryl sulfate (SLS) solution, which is widely used as a surfactant for cleaning shampoos, removes more protein, the most important component of hair, from hair than water. It was confirmed that the elution amount of protein increases as the temperature increases.

In addition, Carla Scanavez et al. used undamaged, healthy blackish-brown hair to clean with SLS at 40 °C, and structural changes in hair that appeared through rinsing, wet combing, heat drying, and dry combing. was observed with an electron microscope, and the relationship between excessive structural damage of hair and hair color change was studied and reported. M. Richena et al. confirmed that washing as well as irradiation caused morphological damage to the hair cuticle.

Since the surface of the skin and fibers also cause damage during the washing process in the same way as the hair, various studies are being conducted to reduce surface damage through the use of mild surfactants or methods of reducing the physical force of washing.

In this way, in order to prevent damage to the cleaning target such as skin, fiber, and hair during the cleaning process, it is important that coacervate, which is a particle formed by combining an anionic surfactant and a cationic polymer, is evenly deposited on the surface to be cleaned. Existing detergents have a problem in that the coacervate produced is too large in particle size to be uniformly deposited on the surface to be cleaned to form a protective film, resulting in damage caused by cleaning.

Under this background, the present inventors have found that a cleaning agent that can effectively block damage to a cleaning target by forming a very uniform and smooth coating protective film on the surface of substrates such as hair and skin by generating fine coacervates of less than 30 μm when washed with water. composition was developed.
