Zinc Oxide
Zinc oxide (CAS 1314-13-2) is consumed in greater tonnage by the rubber industry than by all its other uses combined. It activates the sulphur vulcanisation system, without which accelerators barely work at all.
Alkyl Polyglucoside (APG)
Alkyl polyglucoside (CAS 68515-73-1, INCI Coco-Glucoside) is the rare non-ionic surfactant that stays effective in strong caustic. That alkali stability is why it is specified in heavy-duty and CIP cleaning formulations.
Polydimethylsiloxane (PDMS)
Polydimethylsiloxane (CAS 63148-62-9) is the basic silicone fluid, built on a silicon-oxygen backbone rather than a carbon one. That backbone is what gives it thermal stability and a viscosity that barely changes with temperature.
Isobornyl Acetate
Isobornyl acetate (CAS 125-12-2) is a terpene ester with a clean, fresh pine and camphor odour. It is the standard synthetic replacement for pine needle oil in functional fragrance, where cost and stability rule out the natural.
Calcium Fluoride
Calcium fluoride (CAS 7789-75-5) is the raw material behind essentially every fluorine compound in commerce. Acid grade fluorspar at over 97 percent CaF2 is converted to hydrogen fluoride, and everything fluorinated follows from that.
Fluorite (Fluorspar)
Fluorite, traded as fluorspar, is the mineral form of calcium fluoride. It is sold in two grades that are not interchangeable: acid grade above 97 percent for chemical conversion, metallurgical grade for steel fluxing.
Perlite Ore Sand
Perlite ore is a volcanic glass containing bound water. Heated rapidly past 850 degrees Celsius that water flashes to steam and expands the softened glass up to twenty times, producing a lightweight cellular particle.
Plasticiser
Plasticiser is a class rather than a single product, covering phthalates, terephthalates, adipates, trimellitates and bio-based esters. Selection is a trade-off between efficiency, permanence, cold flexibility and regulatory status.
Sulfur
Sulfur (CAS 7704-34-9) is almost entirely a recovered by-product now, stripped from natural gas and crude oil to meet emissions law. Around 85 percent of world output goes straight into sulphuric acid.
DOTP - Dioctyl Terephthalate
Dioctyl terephthalate, DOTP (CAS 6422-86-2), is the direct non-phthalate replacement for DOP. It is chemically an isomer, differing only in where the two ester groups sit on the benzene ring, but it is not a phthalate.
Sericin Powder
Sericin (CAS 60650-88-6) is the gum protein that binds silk fibres together in the cocoon, and it is removed during degumming. Recovering it turns what was an effluent stream into a hydrophilic cosmetic protein.
Silk Amino Acids
Silk amino acids (CAS 96690-41-4, INCI Hydrolyzed Silk) are silk protein broken down completely to free amino acids. At the lowest molecular weight of the silk range, they act as humectants rather than film formers.
Silk Peptide
Silk peptide (CAS 96690-41-4, INCI Hydrolyzed Silk) is silk protein hydrolysed only partway, leaving short chains rather than free amino acids. That intermediate size is what allows it to form a film while staying soluble.
Silk Powder
Silk powder (INCI Silk Powder) is intact fibroin micronised rather than hydrolysed, so it is insoluble. It works optically and by touch, scattering light to soften the appearance of fine lines and giving a dry, silky slip.
Sodium Cocoyl Isethionate (SCI)
Sodium cocoyl isethionate (CAS 61789-32-0) is a crystalline anionic surfactant, which is what allows a cleansing bar to be pressed at all. Liquid surfactants cannot hold bar structure; SCI can.
Sodium Hyaluronate
Sodium hyaluronate (CAS 9067-32-7, INCI Sodium Hyaluronate) is the water-soluble sodium salt of hyaluronic acid, supplied as a white powder. Molecular weight, not purity, is what separates one grade from another.
