Embodiment A1～A7

[0035] Embodiments A1-A7, Comparative Examples A1-A2:

[0036] Prepare the compound according to the formula table shown in Table 1, carry out skin feeling test, stability test, closed cup flash point test to the compound and cyclopentasiloxane, and carry out the preferred compound Oil compatibility test and pigment dispersion performance test, the specific test steps are as follows:

[0037] (1) Skin feel test: drop an equal amount of the test substance oil on the skin, apply it in a circular motion counterclockwise with the fingertips, feel the skin feel of the oil, and evaluate the test substance oil and cyclopentamethylene by scoring The spreadability of siloxane on the skin, silky feel, fast drying / volatile, moist feeling, powdery feel and softness, and the scores of cyclopentasiloxane in each skin feel It is 0, and the oil score of other test substances ranges from -2 to 2. A high score means that the skin sensory performance is better than cyclopentasiloxane, otherwise...

Embodiment B1、 comparative example B1

[0063] Add compound 5 and cyclopentasiloxane to the hair conditioner according to the formula shown in Table 6, and evaluate the conditioning performance. The specific evaluation steps are as follows:

[0064] Blind test, after washing the hair with shampoo, blot the moisture on the hair with a dry towel, then part the hair in the middle, take an equal amount of sample and apply it evenly from the middle to the ends of the hair (different products are used on the left and right sides respectively), Wait 2 minutes after massaging gently, then rinse off. According to the condition of use, the performance of the conditioner on wet hair and dry hair is scored, ranging from 0 to 5 points, and the higher the score, the better the effect.

[0065] Subjects: 5 people in total, including 4 females and 1 male. Hair types include short, medium and long hair, as well as fine and soft, thick and hard hair.

[0066] The conditioning performance evaluation result of embodiment B1, comparat...

Embodiment C1

[0068] Embodiment C1, comparative example C1:

[0069] According to the formula shown in Table 7, compound 5 and cyclopentasiloxane were respectively added to the skin care cream to evaluate the skin feel performance. The specific evaluation steps are as follows:

[0070] For blind test, take an equal amount of sample and place it on the skin, apply it in circles counterclockwise with fingertips, feel the skin feel, and evaluate the spreadability, silkiness, absorbency, moisturization and softness of the sample on the skin by scoring Sensitive skin performance, ranging from 0 to 5 points, the higher the score, the better the performance.

[0071] Subjects: 5 people in total, including 4 females and 1 male.

[0072] The skin feel property evaluation result of embodiment C1, comparative example C1 is as follows Figure 5 shown.

[0073] from Figure 5 It can be seen that compound 5 can provide a very similar skin feel to cyclopentasiloxane, and compound 5 can provide a relat...
