The information from Jelitto Perennial Seeds suggests that for hard-shelled seeds, mechanical damaging of the shell or treatment with a softener such as Polyethylene glycol 6000 (PEG 6000) can be helpful for quicker swelling. However, there is no specific mention of product number 807491 in particular for this purpose.

Description générale
Polyethylene glycol (PEG) is a synthetic, hydrophilic, biocompatible polymer that has a wide range of uses in PEGylation, surface conjugation, nanoparticle coating, and crosslinking for hydrogels, etc. PEGs are made by polymerizing ethylene oxide via a ring-opening reaction to produce a wide range of molecular weights and molecular weight distributions (polydispersity).
Application
Polyethylene glycol 6000 is a non-ionic surfactant that can be used as a structure-directing agent to prepare mesoporous γ-Al2O3. PEG 6000 induced the formation of the lamellate structure morphology of boehmite nanoparticles with improved textural properties such as high surface area, larger pore volume, and pore size.[1] It is also used in drug formulations to enhance the dissolution rate of the poorly water-soluble drug molecule.[2][3] PEG-6000 can also be used in the purification of nucleic acids via the selective precipitation method. This approach is economically cost-effective and faster than the commonly employed chromatographic purification method.[4]
