Abstract

The present application discloses a hair treatment composition comprising a phase a and a phase B which are non-mixed or non-homogeneously mixed two phases which are effective in solving the problem of "conditioning build-up" by having the phase a and the phase B comprise at least one different surfactant and at least one different cationic polymer.

Description

Hair treatment composition

Technical Field

The present application relates to the field of cosmetic technology, and in particular to a hair treatment composition.

Background

The shampoo with two functions of washing and protecting is needed to realize two functions in the shampoo process: (1) cleaning function: emulsifying greasy dirt and particulate matters on hair and scalp by using surfactant in the formula, so that the greasy dirt is washed away along with water flow; (2) conditioning function: a certain amount of conditioning agent is deposited on the hair, so that the hair scales of the hair are closed, and the hair is smooth, easy to comb and glossy after being washed.

However, one of the pain points of the two-in-one shampoo is conditioning accumulation, namely, after the shampoo is used for many times, the conditioner can be accumulated on the hair continuously, so that the hair becomes sticky and flat.

In the prior art, some manufacturers adopt a formula of an ultralow-content conditioner to slow down conditioning accumulation speed, but the method for reducing the using amount of the conditioner simultaneously brings about weakening of conditioning functions of the shampoo and hair frizziness and the like; shampoo manufacturers have also employed specialty silicone oil materials, such as that disclosed in patent CN105636650a, a hair care composition comprising viscoelastic particles to minimize the excipient materials responsible for sagging and hair volume reduction by allowing the pocket to exhibit specific storage modulus and loss modulus values, however, specialty materials are more limited in availability and increase in cost of use.

The specification and claims do not identify differences in terms of components, but rather differences in terms of the functionality of the components. As referred to throughout the specification and claims, the terms "include" or "comprising" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The description hereinafter sets forth the preferred embodiment for carrying out the present application, but is not intended to limit the scope of the present application in general, as the description proceeds. The scope of the present application is defined by the appended claims.

In this application, the term "conditioning accumulation" refers to the continuous accumulation of conditioning agents on hair, which makes the hair become sticky, flat, etc., and the problem of "conditioning accumulation" can be effectively solved by using the composition described in this application.

In this application, the method of measuring "conditioning accumulation" is not limited in any way, and a conventional method may be selected as required, for example, a test may be performed using a real human hair strand, and the deposition rate of the cationic polymer may be calculated by measuring the mass increment of the hair strand. For example, the deposition rate of cationic polymer can be calculated by subjecting the hair strands to 2 and 6 wash cycles, and measuring the mass increase of the hair strands.

The present application provides a hair treatment composition comprising a phase a and a phase B, both of which contain a surfactant and a cationic polymer, the a phase and the B phase being non-mixed or non-homogeneously mixed two phases;

the phase A and the phase B contain at least one different surfactant;

the phase a and the phase B contain at least one different cationic polymer.

In the present application, the type of the surfactant contained in each phase is not limited at all, and may be any type of surfactant, for example, an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, or the like.

Experimental example determination of deposition rate of Conditioning agent

Experiments to detect "conditioning accumulation" were performed using a bundle of genuine human hair (from the same individual). The deposition rate of the conditioner was calculated by measuring the mass increase of the hair tress through 2 and 6 wash cycles of the hair tress. A "conditioning balance" is considered to be achieved if the relative rate of change of the deposition rate of the conditioning agent after 2 washes and 6 washes does not exceed 5%. Wherein, the relative change rate of the conditioner deposition rate= (conditioner deposition rate for 6 times washing-conditioner deposition rate for 2 times washing)/conditioner deposition rate for 2 times washing.

The operation steps are as follows:

s1, hanging the hair bundle at normal temperature, drying by a normal temperature blower, standing the hair bundle at normal temperature for 24 hours, and balancing water with the environment;

s2, weighing and recording the mass of the dry hair comb;

s3, taking a 200ml plastic sampling bottle, putting all hair bundles into the bottle, and placing the bottle on a balance for zeroing; then, 2.0g (+/-0.1 g) of the samples prepared in the above examples and comparative examples, and 2.0g deionized water (DI water) were added to the flask, and the hair tress-sample-water was stirred with a glass rod for about 3 minutes, allowing all hair tress to be uniformly contacted with the shampoo;

s4, adding 100ml of DI water into a bottle, stirring for about 1 minute by using a glass rod, and pouring the liquid; adding 100m DI water into the bottle, stirring with a glass rod for about 1 minute, and pouring the liquid; adding 100m DI water into the bottle, stirring with a glass rod for about 1 minute, and pouring the liquid;

s5, taking out the starting beam by using tweezers and hanging the starting beam vertically.

For 2 wash cycles, the steps are: S1-S2 →S3→S4→S3→S4→S5→S1→S2；

For 6 wash cycles, the steps are: S1-S2 →S3→S4→S3→S4→S3

→S4→S3→S4→S3→S4→S3→S4Results of the measured deposition rate of the conditioner are shown in Table 2.
