In the process of Single-dose Essence OEM, focus must be placed on seven core elements: technical compliance, production standards, formula design, packaging material selection, quality control management, regulatory adherence, and service support. This ensures that products are safe, effective, and meet market demands. Specific precautions are as follows:

I. Technical Compliance: Ensuring Sterile Production and Advanced Processes

Adopting B.F.S Aseptic Filling Technology

Core Advantage: B.F.S (Blow-Fill-Seal) technology completes container molding, liquid filling, and sealing within a single machine under a sterile environment. It requires no human intervention throughout the process, effectively avoiding secondary contamination.

Data Support: This technology has a cycle time of only 12 seconds, with the liquid exposed to air for <1.5 seconds. The internal microbial control standard is ≤100 cfu/g (far below the industry standard of ≤1000 cfu/g).

Application Scenario: Ideal for encapsulating high-activity ingredients (e.g., pure Vitamin C, Blue Copper Peptide), increasing the preservation rate from ≤40% in traditional bottling to ≥85%.

Automation and Cleanliness Requirements

The production environment must reach a pharmaceutical-grade Class 10,000 standard (higher than the cosmetic Class 100,000). Material pipelines are kept sterile through CIP/SIP (Clean-in-Place/Steam-in-Place) systems.

Eliminate human interference; the blow-fill-seal area is relatively enclosed to ensure air sterility (with sterile filtration for blow-molding gases).

II. Production Standards: Dual Guarantee of Capacity and Quality Control

Production Scale

Select manufacturer capacity based on market demand. For example, Guangdong Quanxin Pharmaceutical Technology possesses 15 fully automated production lines with an annual output of 1.825 billion soft capsule single-dose units, meeting large-scale order requirements.

Startup brands may prioritize manufacturers that support small-batch customization (e.g., MOQs from 5,000 units) to reduce inventory risks.

Quality Control System

Manufacturers must pass certifications such as ISO22716 (Cosmetic GMP) and GMPC (Good Manufacturing Practice for Cosmetics) to establish a full-process quality control system.

Key testing items include:

Microbial Testing: Ensuring no contamination by bacteria or molds.

Stability Testing: Verifying product performance under different storage conditions (e.g., no separation after 72 hours at 40°C).

Irritation and Allergy Testing: Conducted on human skin to ensure safety.

pH Value Testing: Maintaining skin-friendliness (e.g., products for sensitive skin should have a pH close to 5.5).

III. Formula Design: Balance Between Simplicity and Efficacy

Minimalist Formula Principle

Reduce the number of ingredients, prioritizing raw materials with high activity and safety (e.g., pharmaceutical-grade ingredients offer higher concentration and purity).

Avoid adding preservatives, fragrances, alcohol, or other irritating ingredients to lower the risk of sensitivity.

Case Reference: Biohyalux Hyaluronic Acid Barrier Conditioning Essence utilizes 4 types of ceramides + Centella Asiatica extract to achieve repair efficacy while maintaining a gentle formula.

Preserving Efficacy of Ingredients

For easily inactivated ingredients (e.g., pure Vitamin C, Vitamin A), single-dose packaging can significantly improve the preservation rate (from ≤40% to ≥85%).

Formulas must consider ingredient compatibility to avoid contradictions between high-concentration ingredients (e.g., Blue Copper Peptide and EDTA) that lead to precipitation or discoloration.

IV. Packaging Material Selection: Equal Emphasis on Safety and Eco-friendliness

Advantages of B.F.S Soft Tube Packaging

Safety: Avoids glass shards produced when breaking glass ampoules, reducing the risk of cuts.

Portability: Independent single units are suitable for travel or business trips, and there's no need to worry about liquid security restrictions.

Freshness: Uses nitrogen-filling technology (nitrogen purity ≥99.999%) to isolate oxygen and prolong ingredient activity.

Eco-friendly Trends

Some manufacturers (such as Guangdong Quanxin) are researching biodegradable materials to replace traditional plastic shells, with eco-friendly upgraded versions expected to launch in 2026.

Brands can choose manufacturers that support packaging recycling to enhance consumer goodwill.

V. Regulatory Adherence: Compliance is the Prerequisite for Market Access

Domestic Filing and Registration

Assist in completing general cosmetic filings or special cosmetic registrations (e.g., whitening, sunscreen products), providing ingredient lists, test reports, label samples, and other materials.

Ensure accurate label information (e.g., ingredient order, usage instructions, warnings) in accordance with the "Cosmetic Supervision and Administration Regulation."

International Certification Support

For export products, certifications such as EU EC No 1223/2009 or US FDA registration are required to avoid customs clearance risks.

Manufacturers must be familiar with target market regulations and provide targeted solutions (e.g., HALAL certification for Middle Eastern regions).

VI. Service Support: Full-Chain Collaboration to Improve Efficiency

One-Stop Service Capability

Prioritize manufacturers that provide full-chain services including formula R&D, production, packaging design, and logistics (e.g., NBC), reducing communication costs.

Manufacturers should support customized services, such as adjusting packaging specifications based on brand needs (e.g., combinations for 1-day, 2-day, or 4-day usage).

After-sales and Risk Control

Require manufacturers to provide product stability tracking services (e.g., periodic testing of active ingredient content within 12 months).

Sign clear quality responsibility clauses, agreeing on compensation for delays and return mechanisms to reduce cooperation risks.
