Benzalkonium Chloride (BKC) for Personal Care & Cosmetics — CTFA-Compliant Cosmetic Preservative Manufacturer
Vasudev Chemo Pharma manufactures Benzalkonium Chloride 50% and 80% Cosmetic Grade — INCI-listed cationic preservative for hair conditioners, mouthwashes, shampoos, leave-on personal-care products. ISO 9001:2015, GMP, and Halal certified. CTFA-compliant. Direct supply to global cosmetic ingredient formulators.
The Cosmetic Preservation Challenge
Personal-care products are nutrient-rich, water-based environments that support rapid microbial growth — bacteria, fungi, yeasts, and moulds can establish populations within days of contamination. Without effective preservatives, cosmetic products develop visible spoilage, off-odours, pH drift, and (more dangerously) become vehicles for pathogenic infection of consumers' skin, eyes, and mucous membranes.
The Cosmetics Europe Annex V (preservatives positive list), FDA cosmetic regulation, and ISO 11930 (Cosmetic Microbiological Challenge Testing) all require finished cosmetic products to demonstrate adequate preservation across a 12-month or longer in-use period. Choosing the right preservative is one of the most important formulation decisions a cosmetic chemist makes.
How Benzalkonium Chloride Solves It
Benzalkonium Chloride (BKC) is one of the most widely used cosmetic preservatives — listed under INCI name 'Benzalkonium Chloride' in Cosmetics Europe Annex V at maximum 0.1% active in rinse-off products and 0.05% active in leave-on products. As a cationic quaternary ammonium compound, BKC provides broad-spectrum antimicrobial protection against bacteria, fungi, yeasts, and moulds.
Beyond preservation, BKC plays a dual role as a cationic conditioning agent in 2-in-1 shampoos, leave-on hair products, and skin-care formulations — its positively charged head adsorbs onto negatively charged hair and skin surfaces, providing conditioning, anti-static, and substantivity benefits. This combined preservative + conditioner functionality makes BKC unusually cost-effective for cosmetic formulators.
Vasudev Chemo Pharma's Cosmetic Grade BKC 50% and 80% are CTFA-compliant, GMP-certified, Halal-certified (for export to UAE, Saudi Arabia, Malaysia, Indonesia), and supplied with INCI declaration documentation. Buyers across global personal-care brands procure 80% concentrate from our Gujarat facility and dilute to 0.125% (rinse-off) or 0.0625% (leave-on) in finished cosmetic formulations.
Pharmaceutical Preservation in Topical & Eye Care Products
BKC is also the most widely used preservative in eye drops, nasal sprays, contact-lens solutions, and topical antiseptics — appearing as a compendial preservative in USP, NF, BP, EP (Ph. Eur.), IP (Indian Pharmacopoeia), and JP (Japanese Pharmacopoeia). Typical pharmaceutical use is 0.001% – 0.01% active in finished products.
For pharmaceutical OEMs, Vasudev Chemo Pharma supplies GMP-certified BKC 50% and BKC 80% with full COA, SDS, TDS, batch records, and stability data suitable for regulatory submissions to USFDA, CDSCO (India), MHRA (UK), and EMA (EU). The product meets compendial monograph specifications for active content, free amine, alkyl distribution, and impurity profile.
