Pyrrolidone ethanolamine salt (Ethanolamine PCA) is a mild humectant and pH buffer for cosmetics. Provides moisturizing, skin conditioning, and hair care benefits. Used in shampoos, lotions, creams, and scalp treatments. Compatible with surfactants, low irritation potential.

Piroctone olamine is a mild antifungal agent for controlling dandruff and seborrheic dermatitis. Inhibits Malassezia growth, reduces inflammation, and restores scalp microflora balance. Stable in shampoos, lotions, and leave-on products. Safe at recommended concentrations. CAS 68890-66-4.

Ammonium chloride (NH₄Cl, sal ammoniac) is a white crystalline salt used as a nitrogen fertilizer, soldering flux, dry cell electrolyte, buffering agent, and expectorant in cough medicines. Also used in food as E510 (acidity regulator) and in textile dyeing. Soluble in water. CAS 12125-02-9.

Dimethyl disulfide (DMDS) is an organosulfur compound used as a sulfiding agent in petroleum refining, reducing coke formation and passivating catalysts. Also used as a soil fumigant in agriculture and as a reagent in organic synthesis. Colorless liquid with strong garlic-like odor. CAS 624-92-0.

Polysilazanes are inorganic-organic polymers with alternating silicon and nitrogen atoms in the backbone. Used as precursors for silicon nitride ceramics, high-temperature coatings, and electronic materials. Key types: perhydropolysilazane (PHPS) and organopolysilazanes. Provide thermal stability, chemical resistance, and oxidation protection.

Lithium aluminum hydride (LAH) is a powerful reducing agent for converting aldehydes, ketones, esters, carboxylic acids, and amides to alcohols and amines. Used in pharmaceuticals, fine chemicals, and as a hydrogen source. Highly reactive with water; handle under inert gas. CAS 16853-85-3.

Chain extenders are small bifunctional molecules that increase polymer chain length and modify properties. Crucial in polyurethanes, polyamides, and epoxies. Control molecular weight, mechanical properties, and rheology. Common types: diols (1,4-butanediol), diamines (ethylenediamine), and dianhydrides.

Polyurea is a high-performance elastomeric polymer formed by the reaction of isocyanates with amines. Offers rapid curing (seconds to minutes), excellent mechanical strength, chemical resistance, waterproofing, and broad thermal stability (–40°C to +120°C). Used in protective coatings, linings, sealants, adhesives, and lubricating greases.

Polyurea thickener is a non-soap, non-metallic rheology modifier for high-performance lubricating greases. Formed by reacting isocyanates with amines, it creates a 3D polymer network that holds base oil. Provides high dropping point (>250°C), excellent thermal and oxidative stability, water resistance, and long service life. Used in bearings, electric motors, and sealed-for-life applications.

Tocofersolan (Vitamin E TPGS) is a water-soluble non-ionic surfactant derived from natural vitamin E and PEG 1000. Acts as a solubilizer, emulsifier, permeation enhancer, and P‑gp inhibitor. Improves bioavailability of poorly soluble drugs, vitamins, and nutraceuticals. Used in pharmaceuticals, cosmetics, and functional foods. CAS 9002-96-4.
