How to find a suitable water replenishing spray for brands: factory inspection, cooperation conditions and process analysis

  • With the rising demand of consumers for convenient skin care, moisturizing spray has become one of the entry categories of many brands. However, the homogeneity of products on the market is obvious. If brands want to create competitive spray products, the choice of factories will become a key link. The following will be conducted from three aspects: factory capability assessment, cooperation conditions, and processes, for brand reference.


    1、 How to conduct on-site inspections of factory capabilities


    When inspecting a factory, it is not enough to just look at materials. It is recommended to arrange a team to conduct on-site visits and pay attention to the following details:


    Production qualification and hardware level: first, verify whether the factory holds the cosmetics production license, and the scope of the license covers the category of spray and water agent in the "general liquid unit". Simultaneously check the operation records of the workshop air purification system, the model and maintenance logs of the pure water preparation equipment. The water replenishing spray takes water as the basic raw material, and the conductivity of purified water and the microbial control ability are directly related to the product stability.


    Adaptability of filling line and packaging materials: the sense of use of spray products depends largely on the coordination of packaging materials and materials. During the inspection, the factory can be requested to demonstrate the atomization effect of the same batch of materials under different pump head and bottle body pressures, observe the atomization angle, uniformity, and rebound speed after continuous pressing. It is also worth noting whether the factory is equipped with airtightness testing equipment and pressure testing devices.


    Quality control system and sample retention management: Please provide the factory with factory inspection reports and third-party inspection records of similar products in the past year, and pay attention to the fluctuation range of indicators such as pH value and total bacterial count. At the same time, visit the sample room to check if the factory keeps samples of each batch of products for six months after the expiration date, and if the number of samples meets the requirements for retesting.


    R&D support and sampling efficiency: Inquire with the factory if they can complete the material sampling within 5 working days based on the brand's skin preference (such as refreshing or soft). Observe whether the mixing, homogenization, and sterilization equipment in the sampling laboratory is independent of the production workshop to avoid the risk of cross contamination.


    2、 General framework for cooperation conditions


    After both parties confirm their intention, it is usually necessary to clarify the following cooperation conditions:


    Minimum order quantity: most factories set the minimum order quantity of each filling line for water replenishing spray, such as 30000 pieces/batch. Brands should consult with factories on whether there is a tiered minimum order plan based on their own sales forecasts.


    Cost composition: The cost generally includes material processing fees, packaging material procurement fees, filling fees, and quality inspection fees. Some factories may charge separate mold fees or sampling fees, and the brand needs to clarify whether these fees will be deducted in subsequent bulk orders.


    Payment terms and settlement: It is common in the industry to prepay 30% -50% of the deposit for the first order, and settle the final payment after inspection and before shipment. New cooperative brands may request factories to provide past customer cooperation cases to evaluate their flexibility in terms of payment terms.


    3、 The Four Stages of the Collaboration Process


    Requirement docking: The brand provides product concepts, target skin feel, fragrance preferences, and initial packaging material selection plans, and the factory provides feasibility assessments and preliminary quotations.


    Proofing and testing: the factory makes 2 – 3 groups of samples with different formula systems, and the brand conducts internal skin feeling test and machine spray test to determine the final formula.


    Trial production and sample sealing.


    Large scale production and inspection: The factory schedules production, and during the production period, the brand can arrange personnel to conduct on-site spot checks, focusing on deviations in filling net content, nozzle opening times, and sealing. After passing the inspection, arrange logistics and settle the final payment.


    Finally, it should be reminded that when choosing a factory, brands should consider their own positioning and budget, and prioritize cooperation with factories with practical experience in similar products. Before signing the contract, it is recommended to entrust a third-party organization to conduct a social responsibility audit of the factory to ensure compliance with production environment and employee rights.
