14、TS: 3.1Material: Shall consist of a biodegradable material with suitable additives, such as reodorants, buffers, etc, necessary to provide a deodorant meeting the requirements of 3.2. 3.1.1The deodorant shall be free of soaps; non-ionic, cationic, anionic, and amphoteric detergents are acceptable pr
15、ovided the deodorant contains adequate foam depressors to comply with 3.2.2.2.1. 3.1.2The deodorant shall dilute readily with water with minimum agitation. -,-,- AMS 1476BSAEAMS 1476B - 3 - 3.2Properties: The deodorant shall conform to the following requirements; tests shall be performed in accordan
16、ce with specified test methods. 3.2.1Deodorant As Received in Concentrate Form: Shall be tested as the liquid concentrate, except that if the deodorant is received in the form of a solid or gel, it shall be dissolved at the ratio of 1 part by weight deodorant to 5 parts ASTM D 1193, Type IV, water.
17、If a residue (undissolved) is present, filter through a #40 filter paper prior to using for tests. However, such solids should be soluble at intended use dilution. 3.2.1.1Flash Point: Shall be not lower than 93 C (199 F), determined in accordance with ASTM D 56. 3.2.1.2Color: The deodorant shall exh

The dye shall be pH stable and shall not break down when tested for 72 hours 1 in a water solution having a pH of 3 to 11. Formic acid and sodium hydroxide shall be used for adjusting the pH of water solution. 3.2
19、.1.3Storage Stability: The deodorant shall be stable after storage at room temperature for not less than 12 months. The deodorant shall, if supplied as a liquid concentrate, show no evidence of layering or separation and shall contain no lumps or show evidence of skin formation after being subjected
20、 to five freeze-thaw cycles as in 3.2.1.3.1. 3.2.1.3.1Two 6 ounce (175 mL) samples of deodorant shall be placed in two 8 ounce (250 mL) clear glass bottles or in ziplock-type plastic bags, sealed, and exposed for 8 hours 0.25 to -23 C (-9 F), or lower if necessary to completely freeze the deodorant
21、samples. At the end of the freezing period, the samples shall be removed to a room temperature environment and allowed to thaw for 16 hours 0.5. This shall constitute one complete freeze-thaw cycle. The samples shall be subjected to five complete freeze-thaw cycles. At the end of the fifth cycle, th
