4. Production process flow

The whole chain of essence development:

Requirement analysis: The customer provides odor direction (such as "ocean refreshing tone") and application scenarios (car aromatherapy requires high temperature resistance).

Formula design: The perfumer combines spices (such as citrus head fragrance+sandalwood base fragrance), considering the concentration limit of IFRA.

Stability testing: high temperature/light test, compatibility test with substrate (alcohol, wax).

Compliance documents: generate MSDS (Material Safety Data Sheet), IFRA certificate, allergen declaration.

Mass production delivery: Fill according to MOQ (Minimum Order Quantity) and provide OEM/ODM packaging services.

5. Regulations and Certification

5.1 Core Regulations

EU EC No 1223/2009: 26 allergens (such as limonene and linalool) shall be marked for cosmetic essence.

China's "Technical Specification for Safety of Cosmetics": specifies the list of prohibited substances (such as nitromusk).

IFRA Standards: The latest version is the 51st edition, which limits the use of natural ingredients such as oak moss extract.

Note: The application regulations of essence in different fields are slightly different

6. Industry Trends (2024-2025)

Green chemistry: The synthesis of fragrances through biological fermentation methods (such as using yeast to produce rose ketone), replacing traditional petroleum based raw materials.

Intelligent fragrance adjustment: AI algorithms analyze consumer emotional preferences and generate fragrance recommendations (such as "stress relieving and sleep aiding" aromatherapy formulas).

Localized supply chain: brands tend to choose regional essence suppliers to shorten the delivery cycle (for example, Southeast Asian factories serve the ASEAN market).

7. Frequently Asked Questions (FAQ)

Q1: What is the difference between fragrance and essential oil?

Fragrance: manually mixed, with strong odor stability and low cost;

Essential oil: pure natural extraction, short fragrance retention, high price, commonly used in aromatherapy.

Q2: How to evaluate the professionalism of essence suppliers?

Check IFRA compliance documents and whether GC-MS (gas chromatography-mass spectrometry) detection equipment is available;

Request to provide similar scenario cases (such as a high-temperature resistance test report for car aromatherapy).

Q3: How to calculate the proportion of essence added?

Large daily chemical products, such as shower gel, shampoo, and other personal care products, typically account for 0.1% -2%
Aromatherapy products, such as fireless aromatherapy, with fragrance as the main function, usually range from 5% to 20%

The proportion of different carriers added varies and needs to be adjusted according to the characteristics of the carriers.
