Applications: bread, cakes, tortillas, baked and processed foods. Properties: pH (5% solution) 8.0–10.5, CAS 137-40-6. Also known as propanoate de sodium, sodium propanoate, E281, sodium salt of propionic acid, and food preservative E281. Certified Kosher, Halal, CQC, and VeganSu. Available in Monterrey, with shipping throughout Mexico.

Sodium gluconate, technical grade. Fine crystalline white powder, ≥ 98% purity. Highly soluble in water, non-corrosive, and non-toxic, with excellent resistance to oxidation and reduction even at high temperatures. Functions as a set retarder, plasticizer, and water reducer in cementitious systems. Applications: concrete, mortars, plasters, and other construction formulations. Properties: assay ≥ 98.0%, whiteness 55.5–85.0%, reducing substances ≤ 0.50%, chlorides ≤ 0.05%, sulfates ≤ 0.05%, heavy metals (Pb) ≤ 5.0 mg/kg, arsenic ≤ 1.0 mg/kg, pH (5% solution) 6.0–8.0, CAS 527-07-1. Also known as: sodium gluconate. Available in Monterrey, with shipping throughout Mexico.

Trisodium citrate dihydrate Ensign, food grade. White granular or fine powder, soluble in water, insoluble in alcohol. Obtained from the reaction of citric acid and calcium hydroxide, allergen-free. Functions as an acidity regulator, chelating agent, and emulsifier. Applications: food, beverages, and fillings. Properties: pH (5% solution) 7.5–9.0, CAS 6132-04-3, also known as E331. Kosher certified and compliant with USP/FCC specifications. Available in Monterrey, with shipping throughout Mexico.

Hydroxypropyl Methylcellulose, cosmetic and pharmaceutical grade. Yellowish-white powder, nonionic, soluble in aqueous solutions with a pH of 3 to 11 and stable in alcoholic concentrations up to 100%. It presents a viscosity of 3,000 to 5,600 cps, low content of non-dispersible fibers, and excellent compatibility with metallic salts and organic ionic compounds. Used as a thickener, stabilizer, emulsifier, and suspending agent in liquid and semi-solid systems, especially in ophthalmic products due to its high clarity and stability. Applications: eye drops, ophthalmic gels, lotions, creams, topical gels, oral solutions, emulsions, pharmaceuticals, and cosmetics. Properties: pH 6.0–8.5, loss on drying max. 5.0%, viscosity 3,000–5,600 cps. Also known as: HPMC, hypromellose, modified cellulose, gel-forming agent. Available in Monterrey, with shipping throughout Mexico.

Glycerin 99.7%, food grade, USP. Colorless, odorless liquid with high viscosity and sweet taste, fully miscible in water and alcohol. Its high purity (minimum 99.9%) and low impurity content make it ideal for sensitive applications. Functions as a humectant, solvent, preservative, emollient, and viscosity modifier. Applications: cosmetics (creams, lotions, shampoos), pharmaceuticals (ointments, syrups, topical products), food and beverages (flavoring, solvent, and emulsifier), oral care (mouthwashes, toothpastes), tobacco products, among others. Properties: neutral pH, specific gravity 1.2615 (25 °C), APHA 3, water max. 0.017%,…
