Shampoo Filling Machine

Shampoo foam control is achieved through three complementary mechanisms in our filling machines. First, bottom-up filling — the nozzle tip starts submerged at the container bottom and retracts upward as the product level rises, preventing the turbulent splashing that creates foam in top-fill systems. Second, low-velocity fill head design — the product flows through the nozzle at a controlled velocity below the critical turbulence threshold for that product's surfactant system, typically 0.3–0.8 m/s depending on viscosity and foam tendency. Third, overflow prevention sensors — ultrasonic level sensors detect foam accumulation and temporarily pause filling to allow foam to settle before completing the fill cycle.

Our shampoo filling machines handle the full range of shampoo viscosities: ultra-thin clarifying shampoos (100–500 cP), standard shampoos (1,000–5,000 cP), thick moisturizing shampoos (5,000–20,000 cP), and extra-thick conditioners and hair masks (20,000–50,000 cP). For products above 30,000 cP, we recommend the heated hopper option to reduce viscosity to a pumpable range during filling. Viscosity above 50,000 cP (e.g., hair wax, pomade) requires our lotion/cream filling machine with piston pump technology.

Shampoo filling machines used in cosmetic production are usually reviewed against ISO 22716:2007 expectations for production, control, storage and shipment. The project documentation may cover product-contact material records, sanitary design principles, batch traceability support, CE-related machinery files for EU projects, and ISO 22716-related review items according to the final technical agreement.

CIP duration between shampoo product changeovers depends on the degree of product compatibility. Between variants of the same formula family (e.g., switching between two shampoo SKUs using the same base), a hot water rinse (60°C, 10–15 minutes) followed by a sanitizer flush is sufficient — total CIP time 15–20 minutes. Between substantially different products (shampoo to conditioner, or fragrance-sensitive products), a full 3-stage CIP (pre-rinse, detergent wash, final rinse + sanitize) takes 25–35 minutes. Between incompatible product categories (e.g., switching to a product containing different surfactant chemistry), a full CIP with hot water, caustic wash and sanitizer takes 35–50 minutes. Our CIP systems are fully automated with documented validation records per cycle.
