Embodiment 1
[0043] A hair treatment agent composition containing an oil-in-water microemulsion containing 0.1% by mass of amino-terminated polydimethylsiloxane (solid content) was prepared, and used on hair that was decolorized and perm treated and washed with shampoo Use this composition.
[0044] After a predetermined period of time, the concentration of calcium contained in the hair is measured. Specifically, the hair was treated with 50% hydrochloric acid at 90°C for 1 hour, calcium was extracted, and the calcium concentration was measured by ICP emission spectrometry (Simultaneous Mode).
[0045] The change in the calcium concentration in the hair before using the hair treatment composition of the present invention and after using and leaving is shown in figure 1 In the chart.
[0046] As by figure 1 It is clear that by using the hair treatment agent composition of the present invention, calcium in hair is removed. It should be noted that by heating the hair at 60°C during storage, the ...
Embodiment 2
[0048] A sample of the composition shown in Table 1 below (the balance is water) was prepared. Each sample was used on the hair tress that was damaged by the bleaching and perm treatments, and the touch was deteriorated. After drying with a hair dryer, the touch was evaluated.
[0049] Evaluation is carried out by members of a professional evaluation team, and the evaluation is based on the following criteria.
[0050] [Evaluation criteria]
[0051] ×(1): Unsmooth and poor touch
[0052] △(2): Although it is not smooth, the touch is improved
[0053] ○(3): Good feeling
[0054] △(4): Slightly heavier, but feel improved
[0055] ×(5): Sticky, poor touch

Embodiment 3
[0061] The difference in effect due to the type of polysiloxane and the emulsified particle diameter was confirmed.
[0062] A sample containing an emulsion or microemulsion containing polydimethylsiloxane or amodimethicone shown in Table 2 below in an equivalent amount (1% by mass) of solid content was prepared.
[0063] Each sample was used for hair strands that were damaged by bleaching and perm treatments, and the calcium concentration in the hair before and after use was measured using the points of Example 1.
[0064] [Table 2]
[0065]
[0066] As a result, it was combined with emulsions and microemulsions containing polydimethylsiloxane as polysiloxanes (samples A to C) and emulsions containing amino-terminated polydimethylsiloxane (samples D, E). ) In comparison, the microemulsion (Sample F) compounded with amino-terminated polydimethylsiloxane is extremely effective in removing calcium from hair.
[0067] In addition, the contact angle of the hair surface treated with each sa...
