How to find a suitable essence liquid substitute factory for brands: screening criteria and guidelines for cooperation with Demi Estee

For cosmetics brands, choosing a suitable essence liquid substitute factory is related to product quality and market reputation. How to make reasonable judgments among numerous contract manufacturers? Starting from the screening criteria, we will introduce the process of carrying out customized processing cooperation with Daimei Yashi.

1、 Screening criteria of essence liquid substitute factory

1. Qualification and compliance review

First, confirm whether the factory holds the cosmetics production license, and the scope of the license includes "liquid unit" or "essence" products. At the same time, verify its environmental and fire compliance documents. Recent product inspection reports can be requested to confirm that microbiological, heavy metal, and other indicators comply with the "Cosmetic Safety Technical Specification".

2. Production environment and equipment level

The production of essence requires a clean workshop, and the common standard is 100000 level purification. You can inspect the automation level of the workshop air purification system, purified water preparation device, and filling line on site. In terms of equipment, homogenizer emulsifiers, filling and sealing machines, etc. should be regularly calibrated and operation records should be kept.

3. Quality control system

Check whether the factory has established a complete inspection process from raw material storage to finished product delivery. For example, raw material retention samples, semi-finished product pH and viscosity testing, finished product heat and cold resistance stability testing, etc. Request batch retention records and non-conforming product handling reports from the past two years, which can reflect the stability of quality control.

4. R&D and technical cooperation capability

If the brand has an exclusive formula requirement, it is necessary to confirm whether the factory is equipped with R&D personnel and a sampling laboratory. Understand whether it can provide essence liquid proofing of different matrices (water, gel, oil-based) and the proofing cycle (usually 7-15 working days). At the same time, inquire whether assistance is needed to complete the required documents for non registration.

5. Service and Mass Production Flexibility

Evaluate whether the minimum order quantity matches the brand's initial sales expectations (usually 3000-10000 units). Confirm if the factory can provide packaging material selection suggestions, external packaging design coordination, and logistics delivery plans. Also, it is important to understand the flexibility of expedited or batch delivery for orders.

6. Price and reasonableness of payment terms

Request the factory to provide a detailed quotation: material cost, processing fee, testing fee, packaging material procurement service fee, etc. Compare quotes from two to three companies, and be careful to avoid excessively low prices (which may correspond to insufficient quality of raw materials). In terms of payment terms, the usual practice is to prepay 30% -50% and settle the final payment before shipment.

2、 Cooperation process of Demi Estee OEM customized essence liquid

Demi Estee is a factory with essence liquid processing capability, which supports the whole chain customization from formula development to finished product shipment. The cooperation steps are as follows:

Step 1: Requirements Communication

The brand provides product positioning, efficacy requirements (such as moisturizing, brightening, firming), target customer groups, and budget range. Daimei Yashi's business personnel record parameters and preliminarily evaluate the feasibility of the process.

Step 2: Formula selection and sampling

The brand can select basic products from the existing mature formula library of Daimei Yashi, or propose exclusive ingredient combinations (requiring the brand to provide information on raw materials or raw material suppliers). Daimei Yashi's R&D department will complete 2-3 small samples within 10 working days, with attached testing data for each sample's skin feel, absorption rate, acidity and alkalinity.

Step 3: Sample Confirmation and Adjustment

The brand organizes internal trials and provides feedback on adjustments (such as adjusting viscosity and aroma intensity). Daimei Yashi modifies the formula based on feedback and generally provides two rounds of free adjustments. After sample confirmation, both parties shall seal and retain the same sample.

Step 4: Contract Signing and Filing Preparation

The contract specifies the material formula number, packaging specifications, unit price, delivery time, acceptance criteria, and breach of contract liability. Daimei Yashi assists brand owners in organizing product safety assessment materials for subsequent non registration applications.

Step 5: Scheduling and Production

After the brand pays the advance payment, Daimei Yashi purchases raw materials and packaging materials (which can also be directly shipped by the brand's designated supplier). The production cycle is usually 25-35 days, during which the brand can send personnel to supervise the filling, sealing, coding and other processes on site.

Step 6: Finished product inspection and shipment

Randomly sample each batch of products for inspection of appearance, sealing, and content properties, and issue a factory report after passing the inspection. The brand pays the final payment, and Daimei Yashi ships the goods according to the agreed logistics method, and provides copies of all batch production records.

Step 7: After sales traceability

Daimei Yashi retains samples for each batch of products for two years, and can trace the same batch of raw materials and operating section information in case of market complaints.
