CLC 18-410 Smooth PP Treatment Pump, 0.25cc Dosage with External Spring Design

What this packaging is

Precision-dosed at exactly 0.25cc per actuation, the 18-410 Smooth PP Treatment Pump is engineered for skincare formulas where consistency matters. Its standout external spring design keeps the spring completely outside the liquid path — housed in a dry chamber — eliminating spring corrosion and contamination risk from reactive actives. A multi-layer construction adds a second line of defense against leakage. Built from polypropylene with an 18-410 neck finish, it fits a broad range of compatible bottles and airless-style containers used for face serums, eye creams, moisturizers, and spot treatments. Compatible with heat stamping and aluminum shell decoration, this pump gives precision-first skincare brands a functional and brand-ready closure.

Why brands choose this

• External spring eliminates formula contamination risk: The spring sits in a sealed dry chamber, completely outside the liquid flow path. For brands formulating with reactive actives — retinoids, acids, vitamin C — this design prevents spring corrosion that can compromise formula integrity and shelf stability, a real differentiator in clinical and results-driven skincare.
• Consistent 0.25cc dosing built for high-value actives: Each actuation delivers a precise, repeatable dose — critical for concentrated serums, spot treatments, and eye creams where over-dispensing wastes expensive ingredients and under-dosing undermines efficacy. As consumers become more ingredient-literate, dose-controlled packaging reinforces trust in the formula's potency claim.
• Multi-layer leak prevention reduces risk for the full supply chain: The pump's multi-layer construction is engineered specifically to prevent leakage — protecting formula, packaging, and retailer relationships. For brands distributing through e-commerce or multi-step retail, leak integrity isn't optional; it's a baseline expectation that this pump is built to meet.
