  Diamine Inks
Diamine sticks to the traditional ways of manufacturing and only changes formulas were necessary to comply with current legislation.
All Diamine inks are available in large 80 ml bottles; some special inks like their permanent Registrar's Ink come in smaller containers.
All Diamine inks dry pretty quickly on most papers and appear to be safe for vintage pens and for materials with direct contact to the ink.

 Ethylene diamine (CASRN 107-15-3), IRIS, Environmental Protection Agency
Twenty-five uL of a 1% ethylene diamine solution in deionized water was applied to the skin of two groups of 50 mice 3 times/week until death.
Ethylene diamine produced a weakly mutagenic response in four Salmonella typhimurium strains, both in the presence and the absence of an S9 homogenate fraction (Haworth et al., 1983; Hedenstedt, 1978; Hulla et al., 1981).
Ethylene diamine was negative in a sister chromatid exchange assay and HGPRT gene mutation assay in Chinese hamster ovary cells, both in the presence and the absence of metabolic activation.

 Imide prepolymer from bisimide, diamine and tribromophenylmaleimide - Patent 5102981
Imide prepolymers comprising unsaturated bisimides, diamines, and tribromophenylmaleimide in cured state show improved heat resistance, especially soldering heat resistance and flame retardance as well as mechanical properties and are suitable as laminates.
The imide prepolymers of the present invention are defined as comprising (i) an unsaturated bisimide, (ii) a diamine and (iii) tribromophenylmaleimide as essential components.
Alternatively, it is possible to synthesize a prepolymer by melt or solution polymerizing an unsaturated bisimide and a diamine, and add tribromophenylmaleimide to the prepolymer when the prepolymer is dissolved in the foregoing solvent to form a varnish.

 Thermoplastic reinforcing adhesives and substrates coated therewith - Patent 4062820
The copolyamide of claim 4 wherein the equivalent ratio of polymeric fatty acid to aliphatic dicarboxylic acid is in the range 0.92:0.08 and 0.85:0.15 and the equivalent ratio of aliphatic diamine to polyoxyalkylene diamine is in the range 0.95:0.05 and 0.98:0.02.
mixtures of ethylene diamine and hexamethylene diamine, with polymeric fatty acids improves the flexibility at low temperatures, however, the resins lack resiliency and memory and are unable to "snap back" to their original configuration.
Present with the short-chain diamine is a polyoxyalkylene diamine corresponding to the general formula ##STR1## where R is hydrogen or a methyl group and m is a positive integer such that the average molecular weight of the polyoxyalkylene diamine is between about 600 and 5000 and, more preferably, 900 and 2500.

 EPA: Federal Register: [S,S]-Ethylene diamine disuccinic acid; Notice of Filing a Pesticide Petition to Establish a ...
The use of [S,S]-ethylene diamine disuccinic acid, therefore, does not constitute the addition of a foreign material to the soil; rather, it is a compound that soil microorganisms and plants already encounter.
It was concluded that [S,S]-ethylene diamine disuccinic acid was negative in the in vivo cryogenic assay in rats.
Use of [S,S]-ethylene diamine disuccinic acid as a minor component of pesticide formulations applied to growing crops would not contribute significantly to the level of [S,S]-ethylene diamine disuccinic acid found naturally in the environment and to which man is exposed.

 Semi-Continuous Gas-Liquid Catalyzed Reaction of O-Phenylene Diamine and Carbon Disulfide by Tertiary Amine
In the past, the procedure for synthesizing 2-mercaptobenzimidazole (MBI) involves the reaction of o-phenylene diamine and reactants in a mixture of methanol-water catalyzed by active carbon.
The conversion of o-phenylene diamine is increased with the increase in the concentration of tertiary amine, temperature, concentration of carbon disulfide and the flow rate of CS2/CH2Cl2.
However, the conversion is decreased with the increase in the concentration of o-phenylene diamine.

 HUNTSMAN/MATLINPATTERSON / VANTICO(Merger) - COMP/M.312 [2003] ECComm 29 (19 June 2003)
Even if all diamine-based epoxy curing agents suppliers were capacity constrained and even if Huntsman were to choose to supply a greater proportion of Vantico's diamine-based epoxy curing agents requirements (Huntsman currently supplies about […]% of Vantico's diamine-based epoxy curing agents requirements), this would not result in vertical foreclosure of Vantico's competitors.
Within the broad epoxy curing agents market, there is a market segment named amine-based curing agents which includes cycloaliphatic diamines, aromatic diamines and aliphatic diamines (which includes polyetheramines and ether diamines).
Within this market segment there is still a narrower segment of diamines formed by only ether diamines, cycloaliphatic diamines and aromatic diamines which are functionally similar and for which there is a high degree of substitutability from the demand side.

 Diamine Ink - Maybrick Hoax Dissertion
Unless you were looking for it, this preservative would not be spotted by the standard types of ink analyses; these tended to concentrate on dyestuffs.
The Diary camp was urged to take action and test the Diary ink for chloroacetamide, but no action was taken, indeed Mrs Harrison even issued a dismissive statement claiming that the Diamine ink "...contains a modern synthetic dye that any of our analysts would have spotted in the ink of the diary." She was wrong.
So there it was, a laboratory test stating that the lack of sodium in the Diary ink ruled out the modern Diamine product.
