Acceptable Substitutes for DOP – ATI | Knowledge Center
4 cSt PAO (ATI-PAO 4) Ondina / Finevestan. White Mineral Oil. DOS / DEHS (Dioctyl-sebacate) PEG400/Polyethylene Glycol. Peanut Oil. Sunflower Oil. Cottonseed Oil. In January 1992 the Army Surgeon General’s office gave its approval for the use of 4 centistokes (cSt) polyalphaolefin (PAO-4) in lieu of DOP for U.S. Army filter test equipment.

High-performance catalyst is a key factor for the hydrogenation of DOP. Due to the high boiling point of DOP, gas-phase hydrogenation is difficult. While liquid-phase hydrogenation is slow, an autoclave-type reactor is needed. Rh/C is a high-performance catalyst for ring hydrogenation and can convert DOP to DEHCH at low hydrogen pressure, which
Size distributions of test aerosols produced
Enhanced performance coupled with safety considerations suggest that corn oil is an acceptable substitute for DOP especially in those applications of testing human subjects such as quantitative

DOP in HEPA integrity testing. No. It is not acceptable to use drug components, testing to determine conformance to established product processing. This type of procedure Is there an acceptable substitute for DOP to integrity test HEPA filters? Reference: 21 CFR 211.46, Ventilation, air filtration, air heating and cooling, and 211.67
- Is MCCP a good replacement for DOP?
- Interestingly MCCP is accepted by REACH specifications. MCCPwith 52% chlorine is good. One such replacement is citrate-based plasticizer, but experience is that when CP is blended with it at the same level as in DOP, the CP migrates to the surface of product in due course.
- Is DOP better than RoHS?
- RoHS also has the same limits. In Japan it is less than 0.05% or 500 ppm. It is therefore necessary to use its cost-effective replacement, as good as DOP, possibly better that DOP,without causing health problems. Besides, it should be able to accept secondary plasticizer CP, without health hazard.
- Is DOP a good plasticizer?
- Plasticizing efficiency of DOP is considered as “1” and efficiency all other plasticizers is evaluated with reference to DOP. Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns.
- Which is better DOP or DINP?
- DINP has a highermolecular weight and longer carbon chain,(Av. Molecular weight 418) as compared to DOP, molecular weight 390. This results in – Better aging performance, increasing product life. Higher high temperature resistance. 5. Other benefits of DINP over DOP - Electrical insulation performanceis better than DOP.
- Does DINP improve extrusion efficiency?
- DINP has superiority in improving extrusion efficiency. Under typical extrusion processing conditions, DINP can reduce the melt viscosity of the compound more than DOP, which helps to reduce die pressure, reduce mechanical wear or increase extrusion productivity (up to 21%).
