• Establish grade-specific details for Alpha-Arbutin from the supplier and assess filing requirements in the intended market.

5. Sécurité et évaluation des risques

The stated concentration is a cosmetic-development reference; no drug approval or OTC status is conferred by this entry with patch and stability testing still needed for the completed formula.

6. Stabilité et conditionnement

Store sealed bulk away from heat and sunlight; match the pack choice to the system's oxidation risk; confirm final stability and pack compatibility on a representative batch.

7. Formulations d'allégations (à faire / à éviter)

1. INCI et CAS

INCI: Dipotassium Glycyrrhizate · CAS: 68797-35-3

2. Rôle dans la formule

Dipotassium glycyrrhizate is the water-soluble salt of glycyrrhizic acid. The guide does not claim a drug anti-inflammatory effect.

• The serums and creams use-level reference is 0.1–0.5%.

Dissolve in the water phase.

4. Sources réglementaires et conformité mondiale

• A CosIng entry naming Dipotassium Glycyrrhizate does not by itself approve the purchased grade or complete cosmetic.
• The framework in Regulation (EC) No 1223/2009 requires the completed product containing Dipotassium Glycyrrhizate to receive its own safety assessment before the finished product is marketed.
• Compare the received Dipotassium Glycyrrhizate material with its supplier specification and review destination-market filing needs.

5. Sécurité et évaluation des risques

Treat the listed amount as cosmetic-development guidance; it provides no evidence that a drug or OTC monograph applies and the completed formula still requires stability and patch testing.

6. Stabilité et conditionnement

Maintain cool, closed, light-protected storage for the bulk material; review airless or pump options if oxidation presents a concern; follow with stability and packaging checks on the confirmed batch.

7. Formulations d'allégations (à faire / à éviter)

• The cosmetic role of Dipotassium Glycyrrhizate is presented as licorice-salt comfort.

• This ingredient reference provides no basis for medical outcomes, cure language, or a product certification not supported by the available facts.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

Glycerin fills a polyol-humectant role in the listed cosmetic formats. Read its percentage as formulation guidance, not an assay.

3. Niveaux d'emploi typiques (repère de formulation)

• For gels and serums, the reference gives 3–8% as a formulation guide.
• For creams, the recorded level is 2–5% as a formulation guide.

Add Glycerin to the water phase; no separate melt step is needed.

• EU cosmetics rules under Regulation (EC) No 1223/2009 require a safety evaluation of the product containing Glycerin as it will be marketed as a finished-product assessment.
• Review the documentation for the actual Glycerin grade and the filing requirements for the target market.

5. Sécurité et évaluation des risques

The stated concentration is a cosmetic-development reference; it is not evidence of drug approval or OTC authorization and patch and stability testing remain part of finished-product review.

6. Stabilité et conditionnement

Keep bulk material sealed, cool, and out of direct sunlight; evaluate packaging against the formula's susceptibility to oxidation; confirm final stability and pack compatibility on a representative batch.

7. Formulations d'allégations (à faire / à éviter)

• The recorded cosmetic positioning for Glycerin highlights humectant function.

• The ingredient record provides no basis for a drug effect, a clinical cure, or certification status not established for the SKU.
