Preservatives

Nisin (CAS 1414-45-5) is a natural antimicrobial peptide produced via fermentation by Lactococcus lactis, consisting of 34 amino acid residues. As a globally recognized safe, highly efficient, non-toxic natural food preservative (INS No. E234, GRAS certified), Nisin effectively inhibits the growth of most Gram-positive bacteria and their spores. It is widely used in meat products, dairy products, canned food, beverages, condiments and other food industry segments. In 1969, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) officially confirmed the safety of Nisin for food application. In 1992, the Ministry of Health of the People's Republic of China formally approved Nisin as a legal food preservative. As a source manufacturer, we supply high-purity, high-activity Nisin products with stable bulk supply capacity for global customers.

Potassium Lactate (CAS 996-31-6) is the potassium salt of lactic acid. It is a colorless or slightly yellowish transparent viscous liquid with multiple functions including excellent moisturization, pH regulation and antibacterial synergistic effect. As a generally recognized as safe (GRAS) food additive, it is widely used in meat preservation, noodle product quality improvement and personal care moisturizing. As a source manufacturer, we provide food grade and cosmetic grade products with stable bulk supply.

Sodium Lactate (CAS 72-17-3) is a naturally derived multifunctional food additive, appearing as a colorless transparent syrupy liquid. It features three core functions: effective moisturization, pH adjustment, and broad-spectrum antibacterial activity. It is widely used in meat preservation, skin care moisturizing, pharmaceutical infusion and other fields. As a source manufacturer, we provide food grade and pharmaceutical grade products, supporting stable bulk supply.

Calcium Lactate (CAS 814-80-2) is an organic calcium salt with high bioavailability. It features outstanding advantages including high solubility, neutral taste, excellent absorption rate and low gastrointestinal irritation. As a safe and recognized food additive and nutritional fortifier, it is widely used for calcium supplementation and texture improvement in food & beverages, dietary supplements, pharmaceutical preparations and other industries. As a source manufacturer, we provide food‑grade, pharmaceutical‑grade and other multi‑specification products, supporting stable bulk supply.

Calcium Lactate is a compound of lactic acid and calcium with the molecular formula C₆H₁₀CaO₆, and it commonly exists in the form of pentahydrate (C₆H₁₀CaO₆·5H₂O). Its CAS number is 814-80-2 (for the anhydrous form). It appears as a white to off-white crystalline powder or granule, odorless or with a slight characteristic odor. As an organic calcium salt, it features good solubility (especially in hot water) and extremely high bioavailability, along with a mild taste and no bitter or astringent notes. It is widely used as a dietary calcium fortifier, nutritional supplement, acidity regulator and stabilizer, and is ideal for foods, health products and pharmaceuticals with stringent taste requirements.

Lactic Acid 88% (CAS 50-21-5) is a high-purity organic acid from biological fermentation, a colorless/slightly yellow clear viscous liquid with natural sourness, strong bacteriostatic, moisturizing and chelating properties. As a versatile platform compound, it’s a core raw material for food & beverage (acidulant), cosmetics (humectant), biodegradable plastics (PLA monomer) and eco-friendly cleaners. We supply food/industrial-grade variants with stable stock and professional technical support.

Butylparaben (CAS 94-26-8, C₁₁H₁₄O₃) is a paraben with the strongest liposolubility and excellent antifungal efficacy against molds. This white crystalline powder is a high-efficiency preservative for ointments, wax-based products, color cosmetics and high oil-content creams. As a manufacturer, we provide high-standard products and emphasize its strict global regulatory compliance requirements.

Propylparaben (CAS 94-13-3) is a high-efficiency broad-spectrum paraben preservative, a white crystalline powder with the molecular formula C₁₀H₁₂O₃. With exceptional antifungal/anti-yeast activity and superior liposolubility, it is a key raw material for stable preservative systems in cosmetics and pharmaceutical topical preparations. As a manufacturer, we offer full-process quality control and large-scale stable supply.

Ethylparaben (CAS 120-47-8, common name: Nipagin A) is a high-efficiency, broad-spectrum cosmetic and pharmaceutical grade preservative. A core paraben member, it is a white crystalline powder (molecular formula C₉H₁₀O₃) with excellent antifungal/anti-yeast activity and mild properties, acting as a key raw material for high-end skincare, personal care and liquid pharmaceutical preservation systems. As a source manufacturer, we provide stable quality and large-scale supply from production to delivery.

As a professional manufacturer of Methylparaben (CAS 99-76-3), we are committed to providing global customers with high-quality, large-scale and stably supplied preservative raw materials with a full-chain quality control system from raw material sourcing to finished product delivery.
