What is the open flash point requirement for cosmetic grade white oils? White oil is a special deep-refined mineral oil
.
The basic composition of white oil is a saturated hydrocarbon structure, and there are almost no aromatic hydrocarbons, nitrogen, oxygen, sulfur and other substances
.
The distillation range of white oil is generally in the range of 250-450, so it has good oxidation stability, chemical stability, light stability, colorless, odorless, and does not corrode fiber textiles
.
According to the standard requirements, the flash point of white oil is determined by the open cup method.
According to the different grades, the flash point value requirements of white oil are also different.
According to the standard requirements of NB/SH/T0007, the 10 and 15 grades The open flash point of the white oil is not lower than 150℃
.
According to the standard requirements of NB/SH/T0007, the method for determining the open flash point of cosmetic white oil is tested according to the standard GB/T3536.
/T267 "Determination of Flash Point and Fire Point of Petroleum Products (Cleveland Open Cup Method)" The design and manufacture also support GB/T1671-2008 Determination of the flash point of plasticizers ASTMD92
.
According to the above standard specification, the open flash point of white oil of 20,36 grades is not lower than 160℃, and the open flash point of white oil of 50,70 grades is not lower than 200℃
.
Different grades have different flash point requirements
