Guanidine hydrochloride consists of a networkof guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds,it is a strong chaotropic agent. Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a free flowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical.

Choline chloride is an organic compound and a quaternary ammonium salt. It is a weak acid. Choline chloride is the salt of the naturally occurring choline, the pre-stage of the neurotransmitter acetylcholine, which is important for mnemonic and thought-processes. Choline occurs naturally in fungi, hop and kingcups and as integral part of lecithin. Choline chloride is a common food additive in animal husbandry
