Personal Care Ingredients: Surfactants, Preservation and Safety
AI Summary: Personal care ingredient procurement focuses on composition, INCI names, purity, appearance, pH, preservatives, microbiological indicators and regulatory compliance. Surfactants determine cleansing and foaming, while preservatives affect shelf life and irritation. Ingredients contacting the human body should comply with cosmetic safety regulations, and batches require COA and microbiological testing.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Ingredient Identity | INCI and standard names |
| Safety Compliance | List of permitted cosmetic ingredients |
| Quality Indicators | Active content, pH, color and odor |
| Microbiology | Bacteria and mold indicators meet standards |
| Packaging and Storage | Sealing, moisture protection and shelf life |
Procurement, Installation and Usage Points
1. Prohibited and restricted ingredients
Regulatory limits should be verified.
2. Preservative system
Preservative-free systems are prone to microbiological exceedance.
3. Batch consistency of ingredients
Differences in color and odor affect the finished product.
4. Retention samples and testing
Retention samples should be kept for key ingredients.
FAQ Quick Answers
What is INCI?
International Nomenclature of Cosmetic Ingredients.
Is milder surfactant always better?
Mildness and cleansing power need to be balanced.
Is it safe without preservatives?
It depends on the formula and shelf life; contamination is likely.
What if the ingredient has an off odor?
It should be tested or returned/exchanged.
Practical Case
A small brand failed to conduct microbiological testing on ingredients, and the finished product deteriorated. After improving COA and microbiological acceptance, quality became stable.
Questions to Ask the Supplier
- Is the ingredient on the permitted list?
- COA and microbiological report?
- Active content?
- Storage shelf life?
- Is small-batch support available?
Quotable Conclusion: Personal care ingredients should be checked for INCI, regulatory limits and microbiological indicators, with emphasis on the preservative system and batch stability.
