What are the commonly used production processes for customized toner processing, and how can brands assist factories in production

The production process of customized toner processing involves multiple key links, and the collaboration between the brand and the factory directly affects product quality and efficiency. The following provides a detailed explanation from the perspectives of production technology and brand collaboration:

1、 Common production processes for customized toner processing

Formula design and raw material selection

Determine the formula based on brand requirements (efficacy, skin feel, cost), including water phase (deionized water, moisturizer), oil phase (light oil), active ingredients (such as hyaluronic acid, niacinamide), preservatives, etc.

Attention should be paid to ingredient compatibility, for example, certain ingredients should be avoided from being added at high temperatures (such as vitamin C, which is prone to oxidation).

Raw material pretreatment

Deionized water needs to undergo reverse osmosis or distillation treatment to ensure purity;

Some of the raw materials need to be pre dissolved (such as the thickener carbomer, which needs to be neutralized before use).

Mixing and Homogenization

Heating dissolution: Some formulas need to be heated to 60-80 ℃ to promote dissolution (such as oils or solid emulsifiers);

Cooling and feeding: add heat sensitive ingredients (such as plant extracts and essence) when cooling to below 40 ℃;

Homogenization emulsification: Use a homogenizer for high-speed shearing (3000-5000rpm) to ensure the uniformity and stability of the system.

Filtration and sterilization

Micro porous filtration (0.22 μ m) to remove impurities;

The anti-corrosion system must comply with regulations (such as EU EC 1223/2009), commonly using phenoxyethanol and polyols;

Some factories use irradiation or pasteurization (considering ingredient tolerance).

Filling and packaging

Complete filling in a clean workshop (at least 100000 level) to avoid microbial contamination;

Packaging materials (bottles, pump heads) need to be sterilized in advance (such as ozone or ultraviolet radiation).

quality control

Physical and chemical testing: pH value (5.0-7.0), viscosity, cold/heat resistance (-5 ℃~40 ℃ cyclic test);

Microbial testing: in compliance with national standards (such as China's requirement for total bacterial count ≤ 100CFU/g);

Stability testing: Accelerated testing (40 ℃/75% humidity, 3 months) to predict shelf life.

2、 How can brand owners effectively assist factories in production

Collaborative research and development in the early stage

Provide detailed product requirements (such as target audience, competitor analysis), rather than just concepts;

Participate in formula sampling, test skin texture and efficacy (can be entrusted to third-party testing institutions).

Raw material and packaging material control

Designate key raw material suppliers (such as imported active ingredients) to avoid factory replacement;

The compatibility of packaging materials needs to be confirmed with the factory (such as matching the bottle mouth size with the filling line).

Full process supervision of production

Deploy quality inspection personnel to monitor key nodes (such as feeding sequence, sterilization temperature);

Request the factory to provide production batch records and video archives.

Compliance and Certification

Ensure that the factory has qualifications (such as ISO 22716, GMPC);

Assist in filing (such as submitting a full ingredient list and quality inspection report for ordinary cosmetics in China).

Flexible response to problems

Reserve production buffer period (such as raw material delay, equipment failure);

Small batch trial production (500-1000 pieces) will be conducted to verify the process before expanding production.

3、 Common Problems and Solutions

Unstable formula: adjust emulsification process or add stabilizers (such as xanthan gum);

Microbial exceedance: Upgrade the anti-corrosion system or improve the filling environment;

Poor skin texture: Adjust the proportion of thickener based on consumer feedback during trial use.

summarize

Successful customized production relies on the deep involvement of the brand: from formula design to filling details, clear requirements must be identified, and factories with compliance qualifications and flexible response capabilities must be selected. It is recommended that brand owners choose to cooperate with small and medium-sized ODM/OEM enterprises in the initial stage to facilitate quality and cost control, and gradually establish long-term supply chain partnerships.
