Essence liquid OEM processing, essence liquid OEM factory production process

Essence liquid OEM (OEM) processing is a common mode for brand side to entrust factories to produce their own brand products. The following is a description of the typical production process and key links of essence OEM/ODM factory for reference:

1、 Pre communication and requirement confirmation

requirement analysis

The brand clearly defines the product positioning (efficacy, price, target audience), specifications (capacity, packaging form), and formula requirements (active ingredients, skin feel, safety, etc.).

The factory provides a basic formula library or customized R&D solutions.

Sample Testing

The factory makes samples according to the requirements, and the brand confirms the product texture, odor, effect, etc.

Stability testing (high temperature, low temperature, light exposure, etc.) and safety testing (microorganisms, heavy metals, irritants, etc.) are required.

2、 Contract signing and qualification review

contract terms

Clearly define the processing content, price, delivery cycle, quality standards, intellectual property ownership (formula, packaging design), confidentiality agreement, etc.

Special attention should be paid to breach of contract liability, return terms, and after-sales service.

Qualification review

The factory needs to provide a business license, cosmetics production license (such as China GMPC, ISO22716 certification), product filing certificate, etc.

The qualifications and testing reports of raw material suppliers must be complete.

3、 Production process

Raw material procurement and inspection

The factory purchases raw materials (which must comply with national cosmetic safety standards) and conducts on-site testing (such as microbiological, heavy metal, and ingredient content).

Formula production

Weighing ingredients: Accurately weigh the raw materials according to the formula.

Mixing and homogenization: Mixing is carried out in a clean workshop using equipment such as an emulsifying pot and mixer to ensure uniform composition of ingredients.

Sterilization filling: Using sterile filling equipment for packaging to avoid contamination.

Semi finished product testing

Conduct pH value, viscosity, active ingredient content and other indicator tests on semi-finished products.

Packaging processing

Packaging material procurement: The brand provides or the factory purchases packaging materials (bottle body, bottle cap, label, etc.) that meet environmental and transportation requirements.

Packaging design: Printing labels, assembling bottle bodies, ensuring complete information (ingredient list, production license number, shelf life, etc.).

4、 Quality Control and Compliance

Finished product inspection

Sampling and testing of microorganisms, sensory indicators (color, odor), stability, etc. by batch.

Provide third-party testing reports (such as SGS, National Cosmetics Quality Supervision and Inspection Center).

Filing and Compliance

In China, it is necessary to complete the registration of domestically produced non special purpose cosmetics (which can be checked through the "Cosmetics Supervision" APP).

Export products must comply with the regulations of the target country (such as EU EC 1223/2009, US FDA, etc.).

5、 Delivery and follow-up services

Logistics and Acceptance

The factory arranges transportation and the brand inspects the goods (quantity, packaging integrity, quality inspection report).

after-sale service

The factory provides quality problem handling within the warranty period (such as returns and exchanges, formula optimization).

Precautions for choosing an OEM factory

Factory strength: Priority should be given to factories with research and development capabilities, advanced equipment, and stable production capacity.

Cost control: Clarify the composition of packaging materials, raw materials, processing fees, and other expenses to avoid hidden costs.

Risk avoidance: Sign detailed contracts, retain samples and testing reports, and prevent formula leakage or quality disputes.

If further details are needed (such as cost estimation, factory recommendations), specific requirements can be supplemented.
