Sodium nitrite is a chemical compound with various industrial and culinary applications. In the food industry, it is commonly used as a preservative and color fixative, particularly in processed meats like bacon, hot dogs, and ham, to inhibit bacterial growth and maintain product color. Beyond its role in food preservation, sodium nitrite is utilized in chemical processes, such as the production of dyes and pharmaceuticals, as well as in some cooling and heating systems to prevent corrosion. However, its use in food has raised concerns due to potential health risks associated with the formation of nitrosamines, which are known carcinogens, when exposed to certain conditions. Consequently, regulatory limits and guidelines exist to ensure its safe use in food products.
Ammonia is a chemical comprising of nitrogen and hydrogen. It is designated in chemical notation as NH3. Ammonia is extremely soluble in water and is frequently used as a water solution called aqua ammonia. Ammonia chemically combines with water to form Ammonium hydroxide. Anhydrous ammonia which is essentially pure (over 99 percent) ammonia. "Anhydrous" is a Greek word meaning "without water;" therefore, anhydrous ammonia is ammonia without water. Refrigerant grade anhydrous ammonia is a clear, colorless liquid or gas, free from visible impurities. It is at least 99.95 percent pure ammonia. Water content be above 33 parts per million (ppm) and oil cannot have a content above 2 ppm. Preserving the purity of the ammonia is essential to ensure proper function of the refrigeration system. 99.95% pure colorless : liquid/gas Capacity - 3500 ton/day
Caprylhydroxamic acid could be used as a replacement for traditional preservative in cosmetics. It still has a highly effective anti-bacterial capability in neutral environment. However when under the same circumstances, the others will be weakened. Application: Caprylhydroxamic acid may be used in emulsion. Anhydrous and surfactant systems. These include creams, lotions, shower gels and make-up. It may be added to the water phase, at ambient or hot temperatures, or may be added post-emulsidication of O/W emulsions. We do recommend avoiding lengthy exposure to elevated temperatures: for example, maximum two hours at 90C, or maximum six hours at 60C.
Dimethyloldimethyl hydantoin is a popular preservative with moderate sensitizing potential, it is used to control against mold, mildew, and bacterial spoilage. This preservative is similar to imidazolidinyl urea, as both act by releasing formaldehyde into the formulation. Cosmetic expert panels have determined that Dimethyloldimethyl hydantoin has an excellent safety record for use in both leave-on and washoff cosmetic preparations. Maximum-use concentrations are set at 0.2 percent in the u.S. and 0.6 percent in the european union. Dimethyloldimethyl hydantoin stands for dimethylimidazolidine, though in a listing the acronym is rarely spelled out.
2-phenoxyethanol is an aromatic ether that is substituted on oxygen by a 2-hydroxyethyl group. It has a role as an antiinfective agent and a central nervous system depressant. It is a primary alcohol, a glycol ether and an aromatic ether. Phenoxyethanol is chemical preservative, a glycol ether often used in dermatological products such as skin creams and sunscreen. It is a colorless oily liquid.

What is Oligopeptide-10?Oligopeptide-10 has broad-spectrum activity against many types of organisms, including p. acne bacteria. Oligopeptide-10 is A short bioactive peptide consisting of fifteen naturally occurring amino acids that provides anti-microbial activity against p-acne bacterium. Oligopeptide-10 has potent activity against Propionibacterium acnes causing rapid cell death. It binds to negatively charged surface elements (lipoteichoic acids) of bacteria enabling access to its primary target, the cytoplasmic membrane which causes a lethal osmotic imbalance within the bacteria. Due to this unique mechanical mechanism of action bacteria have a very low probability of becoming resistant and bacteria resistant to other antibiotics remain susceptible to Oligopeptide-10. In addition, it neutralizes pro-inflammatory bacterial components, reducing redness. In independent studies Oligopeptide-10 has been shown to be non-cytotoxic, non-mutagenic, non-irritating and non-sensitizing.Used in many acne products to enhance natural defense systems, Oligopeptide-10 is an anti-microbial peptide derived from plant amino acids that is highly synergistic with salicylic acid. Studies have demonstrated that Oligopeptide-10 has broad-spectrum activity against many types of organisms, including p. acnes bacteria. Clinical studies have shown a significant reduction in the appearance of blemishes and red, blotchy spots after using products with Oligopeptide-10.
DBNPA is widely used in industrial circulating water systems, large air-condition, and large centers of sewage treatment to eliminate microorganisms and algae and shuck off clay. DBNPA is also used in the process of paper making to prevent reducing the quality of paper by the generation of microorganisms. DBNPA is suitable for metal cutting of cooling liquor, recovery system of oil, latex, and ply-woods as anti-spy biocides. DBNPA has the following advantages: easy to handle; no unusual oxidation hazards; similar performance and safety in paper and oilfield applications; used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria. DBNPA has exhibited outstanding efficiency against bio-films and a broad spectrum of bacteria, fungi, and yeasts. Additionally, DBNPA series products are used in the short-term preservation of coatings and coating additives such as latex, starch, and mineral slurries. DBNPA is a fast-acting/quick-kill biocide that is broad-spectrum and does not contain or release formaldehyde.
