Embodiment 1

[0058] conditioning test

[0059] Before shampooing, hair tresses were treated with a pre-shampoo conditioning composition formulated as follows (Asian hair, supplied by International Hair Importers & Products, USA): a copolymer comprising acrylamidopropyltrimethylammonium chloride and acrylamide (N -Dur Hance TM AA2000) hair gel formula (FCNW-LO-1)

[0060]

[0061] Before shampooing the tresses, treat the tresses with the above-mentioned hair care gel formula, and then rinse with a commercially available shampoo containing anionic surfactants and silicone oils (trade name: Dove Nourishing Moisturizing Shampoo) Hair strands, that is, the shampooing process of "condition first, then wash".

[0062] The hair tresses used for comparison were hair tresses Nos. 1), 2) and 4) shampooed as described below, wherein No. 3) was a sample hair tress shampooed according to the above method of the present invention.

[0063] 1) Hair tresses that are only washed with the above-mentio...

Embodiment 2

[0082] Hair Damage Protection

[0083] The hair surface treated according to "conditioning first, then washing" has a very significant protective effect on daily damage due to the protective film formed by the acrylamidopropyltrimethylammonium chloride / acrylamide copolymer and anionic surfactant complex. In this example, using the hair bundles numbered 1)-4) prepared in Example 1, the protective efficacy of the composite protective film under the three daily damage pressures of environmental pollution, ultraviolet rays, and hot air were respectively simulated.

[0084] By testing the level of tryptophan in the above-mentioned hair strands to characterize the degree of loss of hair caused by the above pressure, the test of the level of tryptophan refers to the literature: "Niu Lijuan, Qu Xin, research on hair damage caused by the pollution environment of cigarette smoke as a model, The method in Daily Chemical Industry, Vol.47No.10, October 2017, see the test results Figure 1...

Embodiment 3

[0094] Hair Color Protection

[0095] The hair surface treated according to "care first, then wash" is also very effective in preventing color fading after dyeing due to the protective film formed by acrylamidopropyl trimethylammonium chloride / acrylamide copolymer and anionic surfactant complex. significantly. The dyed hair tress was dyed with a commercially available hair dye cream (Clairol Textures & Tones) (Asian hair, provided by International Hair Importers & Products, USA).

[0096] In the present embodiment, comprise following three kinds of modes of washing dyed tresses:

[0097] 1) Use the hair care gel (same as in Example 1) to treat the dyed hair tress each time, and then wash it with the above-mentioned commercially available shampoo;

[0098] 2) each use of a commercially available shampoo containing acrylamidopropyltrimonium chloride / acrylamide copolymer (add acrylamidopropyltrimonium chloride / acrylamide copolymer to the above commercially available shampoo); a...

Abstract

The invention discloses an application of a cationic polymer in a pre-hair washing conditioning composition; a complex is formed from the cationic polymer with an anionic surfactant in a shampoo in asubsequent shampoo procedure, and the hair conditioning improvement, damage repair, pollution resistance, hair coloring and hair protection are facilitated.

Description

technical field [0001] The present invention relates to a cationic polymer, such as a homopolymer of acrylamidopropyltrimethylammonium chloride or a copolymer of acrylamidopropyltrimethylammonium chloride and acrylamide, polyquaternium 6, polyquaternium 113 et al. in the field of hair care, in particular, relates to the use of cationic polymers in pre-shampoo procedures. Background technique [0002] Human hair can become dirty due to contact with the surrounding environment and due to the sebum production of the scalp. Dirty hair gives it a dirty feel and is unattractive in appearance. Dirty hair requires regular shampooing, which can cause hair damage. In addition, due to the increasing daily damage pressure of hair, such as frequent perm dyeing, hot hair dryer treatment, external environmental pollution, and ultraviolet damage pressure, consumers are more urgently in need of effective protection against daily damage. In addition, damaged hair and wet hair are easy to ta...
