Mineral Oil
Mineral oil is a highly refined petroleum distillate stripped of aromatics and unsaturates. White oil grades meet pharmacopoeial purity and are used where the oil will contact skin, food or pharmaceuticals.
Cyanocobalamin
Cyanocobalamin is the synthetic, most stable form of vitamin B12, carrying a cyanide group at the cobalt centre. The body must convert it to an active coenzyme form before it can be used.
Mecobalamin
Mecobalamin, methylcobalamin, is one of the two coenzyme forms of vitamin B12 the body actually uses. It is the cofactor for methionine synthase, which is why it is specified where methylation support is the objective.
Hydroxocobalamin
Hydroxocobalamin is the injectable form of vitamin B12 and, at high dose, the standard antidote for cyanide poisoning. It binds cyanide directly at its cobalt centre to form cyanocobalamin, which is excreted.
Cobamamide
Cobamamide, adenosylcobalamin, is the second coenzyme form of vitamin B12 and the one that predominates inside cells. It is the cofactor for methylmalonyl-CoA mutase, a mitochondrial rather than cytosolic enzyme.
L-Phenylalanine
L-phenylalanine is an essential aromatic amino acid, produced by fermentation. Its largest single industrial use is as one of the two amino acids from which aspartame is synthesised.
Acarbose
Acarbose is an alpha-glucosidase inhibitor used to control post-meal blood glucose. It works entirely within the gut, blocking the enzymes that break starch into absorbable sugar, rather than acting systemically.
Ubidecenone
Listed here as Ubidecenone, this material is ubidecarenone, the INN for coenzyme Q10 (CAS 303-98-0). It is the lipid-soluble electron carrier of the mitochondrial respiratory chain and a well-established antioxidant.
Sodium Gluconate
Sodium gluconate (CAS 527-07-1) is a chelating agent that keeps working in strong alkali, where EDTA and phosphates fail. That single property makes it the standard sequestrant for caustic cleaning and bottle washing.
Lysine
Lysine is the first limiting amino acid in pig and poultry diets built on cereals. Supplementing it lets a formulator cut total crude protein, which reduces feed cost and nitrogen excretion at the same time.
Dibutyl Phthalate (DBP)
Dibutyl phthalate, DBP (CAS 84-74-2), is a low molecular weight phthalate with strong solvating power. It is classified as toxic for reproduction in the EU and requires authorisation under REACH.
Dioctyl Adipate (DOA)
Dioctyl adipate, DOA (CAS 103-23-1), is an aliphatic rather than aromatic plasticiser. Its flexible straight-chain backbone is what gives PVC genuine low-temperature performance, down to around minus 40 degrees Celsius.
Trioctyl Trimellitate (TOTM)
Trioctyl trimellitate, TOTM (CAS 3319-31-1), carries three ester groups instead of two, which raises its molecular weight sharply. That is what makes it the plasticiser for cable rated to continuous high temperature.
Diisononyl Phthalate (DINP)
Diisononyl phthalate, DINP (CAS 28553-12-0), is a high molecular weight phthalate. Its larger branched chains make it far less migratory than DOP and it is not classified as a reproductive toxicant, though toy use is restricted.
Dioctyl Phthalate (DOP)
Dioctyl phthalate, DOP or DEHP (CAS 117-81-7), was the benchmark PVC plasticiser for decades. It is classified as toxic for reproduction in the EU and is on the REACH authorisation list, so use requires authorisation.
Calcium Stearate
Calcium stearate is the calcium salt of stearic acid, a vegetable-derived white soap melting at 149-155C, used as an acid scavenger, co-stabiliser and internal lubricant. It is supplied in 125, 200 and 325 mesh, and as beads and granules.
Zinc Stearate
Zinc stearate is the zinc salt of stearic acid, a vegetable-derived white soap used as a PVC co-stabiliser, mould release agent and anti-tack dusting powder in rubber. It melts considerably lower than calcium stearate, at 119-125C.
Glycerol Monostearate
Glycerol monostearate is a non-ionic glycerol ester of stearic acid, a milky white to pale yellow waxy or powdery solid, odourless and tasteless, freezing at 60-70C. It is supplied in 40% and 90% monoglyceride grades.
Epichlorohydrin (ECH)
Epichlorohydrin (ECH, CAS 106-89-8) at 99.9% minimum purity with water held to 0.02%. The reactive chlorinated epoxide from which bisphenol A epoxy resins, paper wet-strength resins and water treatment polyamines are made.
Triethylamine
Triethylamine (CAS 121-44-8) at 99.5% minimum, the tertiary amine base used to scavenge acid in pharmaceutical and agrochemical synthesis and as the gas-phase catalyst in foundry cold-box core making.
