Description

Description: TECHNICAL FIELD The present invention relates to a shampoo composition containing a silicone emulsion.

BACKGROUND OF THE INVENTION Human hair becomes soiled by contact with the surrounding environment and from sebum hidden in the scalp. Hair stains can cause hair to have a dirty or unattractive appearance. Hair stains always require regular shampoos.

Hair washing cleans hair by removing excess dirt and sebum. However, shampooing makes the hair moist, tangled and generally uncoupled. During the drying of the hair, often due to the natural fats of the hair and other natural conditioning and wetting ingredients, the hair becomes dry, rough,
It becomes dull or crumpled. In addition, hair hinders combing and usually involves "fly-away ha".
This leads to an increase in the electrostatic level during drying which leads to an undesirable "split end" phenomenon, especially in long hair.

Various approaches have been taken to alleviate these post-shampoo problems. These approaches are
It ranges from the application of post-shampoo to hair conditioners such as leave-on and rinse-off products to hair conditioning shampoos that attempt to both clean and condition the hair from a single product. Hair conditioners are typically applied in the next separate stage of shampooing. Hair conditioners are either rinse-off or leave-on, depending on the type of product used. However, hair conditioners have the disadvantage of requiring another inconvenient treatment step. Conditioning shampoos are highly desirable products as they provide cleansing and conditioning benefits to the hair in one step.

A wide variety of conditioning actives have been proposed to provide a hair conditioning benefit to a cleansing shampoo base. However, they are not entirely satisfactory.

One problem relates to the compatibility of anionic detersive surfactants with many conventional cationic conditioning agents. Efforts have been made to minimize adverse interactions through the use of alternative surfactants, but because of their overall good detergency, the use of anionic surfactants in a certain range is still very poor. That is desirable. On the other hand, some users desire a mild or non-irritating shampoo composition that usually contains another class of surfactants along with the anionic surfactant. Accordingly, shampoo compositions that are compatible with a wide variety of detersive surfactants are desirable.

Materials that can provide overall conditioning benefits while maintaining cleaning performance through the use of anionic detersive surfactants are silicone conditioning agents. However, shampoos containing silicone conditioning agents tend to give the hair an undesirable feel after drying the hair, such that a covered, heavy or dirty hair feel remains. In addition, a suspending agent such as an acyl derivative is required to provide a well-dispersed, storage-stable shampoo composition containing a silicone conditioning agent. Combinations of silicone conditioning agents and their suspending agents often give formulations which are milky in appearance and relatively viscous. This is especially true for suspending agents such as ethylene glycol stearate.

The desired hair feel and instability observed with the silicone conditioning agent is believed to be due to the particle size of the silicone conditioning agent. This is particularly noticeable when the silicone has a high molecular weight. Although high molecular weight silicone polymers are known to have advantageous conditioning benefits, such as smoothness and combability, they also tend to have large particle sizes and are thermodynamically poor. It is stable. It is known that mechanical shearing produces small particle size fluids. High molecular weight silicone polymers are too viscous to emulsify down to the desired particle size. Therefore, high molecular weight silicone polymers could not be formulated at levels that would provide the desired conditioning benefits without the aid of suspending agents.

Thus, it is stable without suspending agents and provides improved conditioning benefits overall. There remains a need to provide shampoo compositions containing high molecular weight silicone polymers.
