4. SPECIFICATION
Physical Appearance
Yellow to Orange clear liquid
Identification (HPLC)
Identical
Boiling Point
217 - 222 °C
Purity
NLT 98%
5. APPLICATION
Phenyl-propanedione (PPD) is Norrish type I photoinitiator suggested as an effective alternative photoinitiator in order to reduce yellowing effect.
The absorption peak of PPD is in the near UV region (UVA) and extends slightly into the visible wavelength. Thus, it could be considered a better UV initiator than an efficient visible light photoinitiator.
1-Phenyl-1,2-propanedione, usually used as a low-toxic LED photoinitiator and food additive

Q1: What is Saracure PPD (1-Phenyl-1,2-propanedione) and what type of photoinitiator is it?
A1: Saracure PPD (CAS 579-07-7, C9H8O2, mol. wt. 148.16) is a Norrish Type I photoinitiator supplied as a yellow to orange clear liquid with purity NLT 98% and a boiling point of 217–222°C. Its absorption peak is in the near-UV (UVA) region, extending slightly into the visible wavelength — giving it sensitivity across both UV and the lower edge of visible light.
Q2: What distinguishes Saracure PPD from conventional photoinitiators in terms of yellowing?
A2: PPD is specifically recommended as an effective alternative to conventional photoinitiators to reduce the yellowing effect in cured formulations. Yellowing is a common problem in UV-cured coatings and inks exposed to sunlight, and PPD's structure minimizes this tendency — making it preferred for light-colored or transparent applications where visual clarity is important.
Q3: What is the significance of Saracure PPD being considered a low-toxicity photoinitiator and food additive?
A3: 1-Phenyl-1,2-propanedione is recognized as a low-toxic LED photoinitiator and is also used as a food additive (flavoring agent), reflecting a favorable toxicological profile. This makes it suitable for use in food-packaging inks and coatings where migration limits and safety requirements are stringent.
Q4: What are the regulatory inventory listings for Saracure PPD and are there any compliance gaps?
A4: It is listed on EINECS, EC Inventory, US TSCA, China IECSC, and Canadian DSL — providing broad global coverage for most major markets. It is not currently listed on Korea KECL, Canadian NDSL, or Japan ENCS, so buyers supplying those markets should verify local compliance.
Q5: Does Sarex manufacture and export Saracure PPD for UV-curing and food-packaging ink applications globally?
A5: Yes, Sarex is a leading fine chemical manufacturer and exporter in India, producing Saracure PPD at 50 MT annual capacity and supplying it in 180 kg HDPE drums to UV-curing and printing ink producers in more than 40 countries. Note that it is classified as a hazardous material (UN No. 3077) and must be shipped accordingly.
