The test was conducted on five male and five female panelists. Each panelist used the
samples after shampooing, and evaluated the properties described in Table 1 by touch while applying conditioner to hair, immediately after blow drying, and the next morning (approx. 10 hours after). The evaluation criteria are shown below, with the results showing the average value of each panelist's evaluation results.

1 : Very poor2. Antistatic Property
As shown in Table 2, ECONOL TM-22 imparts a high antistatic property to hair.Cationic Surfactant Voltage of Frictional Electricity V ECONOL TM-22 170 (Comparison)
Stearyltrimethylammonium chloride180 No cationic surfactant (control) 1,980 Materials and Methods:
Materials:
Samples were prepared by immersing wool muslin (30×30 cm) for 60 seconds in a mixture (40 °C) of 20 g of hair conditioner, formulated as described in Table 1, and 500 mL of water. They were then washed under running water for 30 seconds, and blow-dried. They were kept at 25 °C, 45 % R.H. for approx. 8 hours.
Method:
The voltage of frictional electricity was measured using a rotary static tester devised by the Chemical Research Institute at Kyoto University. The lower the value, the higher the antistatic property.3. Coefficient of Kinetic Friction
As shown in Table 3, hair conditioners containing ECONOL TM-22 lower coefficients of kinetic friction on hair, thus this product prevents hair damage resulting from brushing.Moving Rate / Cationic Surfactant 0.9 m/min 18 m/min ECONOL TM-22 0.181 0.241 (Comparison)

Materials:
Samples were prepared by dipping hair in each hair conditioner formulated as described in Table 1 and rinsing with water. They were then kept at 25 °C, 65% R.H. for approx. 8 hours.
Method:
The coefficient of kinetic friction was measured according to the RÖeder method and calculated using the following equation.
4. Safety Data
A. Biodegradability
As shown in Figure 1, behenyltrimethylammonium chloride, the main active ingredient of ECONOL
TM-22, is more easily biodegradable than stearyltrimethylammonium chloride and cetyltrimethylammonium
chloride. However, the biodegradability of this product is not classified as easily biodegradable, because the biodegradability does not exceed 70%.
Materials and Methods:
Materials:
Samples were prepared by using 40 wt ppm (active ingredient) aqueous surfactant solutions as described in Figure 1.
Method:
The biodegradability was measured using 30 wt ppm of active sludge in accordance with the DOC Die-Away Test of OECD Test Guideline (accepted on July 17, 1992).B. Acute Toxicity
Based on data from a similar product by Sanyo Chemical, the acute toxicity of ECONOL TM-22 is considered to be low.
The LD50 of a similar product (behenyltrimethylammonium chloride : stearyl alcohol,
approx. 45 : 55) is as follows : LD50 >2,000 mg/kg (oral, rat).
C. Skin Irritation
Based on data from a similar product by Sanyo Chemical, the skin primary irritation of ECONOL TM-22 is considered to be mild.
The skin primary irritation of a 50 wt % aqueous solution containing the similar product
(behenyltrimethylammonium chloride : stearyl alcohol, approx. 45 : 55) is mild (rabbit, OECD method). P.I.I.= 0.3 (Draize criteria)
