How to Choose the Right Spray Pump? A Guide to Viscosity, Spray Patterns, and Compatibility

Professional Solutions by Zhangjiagang XinYe Chemical Sprayer Co., Ltd.

In cosmetic, fragrance, and personal care product packaging, spray pump selection directly impacts user experience and product performance. As an industry-leading spray pump manufacturer , Zhangjiagang XinYe Chemical Sprayer Co., Ltd. leverages nearly 20 years of experience (since its founding in 2006) and combines fully automated production with strict quality control (ISO9001 certified) to provide professional selection guidance. Here are the key considerations:

1. Selecting Pump Type Based on Product Viscosity

Spray pump suitability highly depends on liquid viscosity (unit: cps):

• Low viscosity (1-100cps) : Such as water-based perfumes and toners, suitable for Xinye standard fine mist pumps with even, delicate atomization.
• Medium viscosity (100-1,000cps) : Such as lotions and sunscreen sprays, require reinforced spring pumps (like Xinye's HP series) to ensure smooth spraying.
• High viscosity (1,000-10,000cps) : Such as serums and oils, recommend piston pumps or aerosol valves to prevent clogging.

Xinye Advantage : The company controls a complete industrial chain from aluminum stamping, injection molding to oxidation treatment, allowing customization of pump structures for different viscosities.

2. Spray Patterns: Atomization Effect and User Experience

Spray pattern affects product application scenarios:

• Fine Mist : Suitable for perfumes and setting sprays (Xinye's FM series with droplet diameter ≤50μm).
• Fan Spray : Ideal for body sprays or disinfectants, with wide coverage.
• Directed Stream Spray : Used for precise application (e.g., serums).

Xinye Technical Support : Fully automated inspection equipment ensures each batch meets spray angle (e.g., 80° or 360°) and droplet uniformity requirements.

3. Material Compatibility and Chemical Stability

• Content Compatibility :
  • Alcohol-based products (e.g., perfumes) require special inner plugs (like PTFE coating) to prevent corrosion.
  • Oil-based formulas (e.g., essential oils) should avoid regular rubber, using EPDM seals instead.
• Environmental Requirements : Xinye offers BPA-free, recyclable aluminum pumps compliant with EU REACH regulations.

Xinye Quality Control : Oxidation treatment enhances aluminum corrosion resistance, validated through 48-hour salt spray tests.

4. Packaging Compatibility: Bottle Neck Sizes and Design

• Common neck diameters: 18mm, 20mm, 24mm (Xinye supports non-standard customization).
• Compatibility testing: Recommended to provide sample bottles for vacuum seal tests (Xinye lab can simulate transport conditions to detect leakage risks).

5. Special Function Requirements

• Child Safety Locks : Prevent accidental activation (e.g., household cleaners).
• Dosing Sprays : Fixed amount per spray (e.g., medicinal sprays).
• Electric Pump Integration : Xinye R&D team can collaborate on smart spray solutions.
