1. INCI et CAS

INCI: Palmitoyl Tripeptide-1 · CAS: 147732-56-7

2. Rôle dans la formule

Palmitoyl tripeptide-1 is a cosmetic lipopeptide. The guide uses a low ppm-to-0.05% framing and does not claim a clinical lift.

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

• The serums and eye creams use-level reference is about 2–10 ppm of pure peptide, or as the supplier blend states in this reference.

Follow the supplier blend TDS. Many trade blends are already diluted.

4. Sources réglementaires et conformité mondiale

• CosIng provides reference information for Palmitoyl Tripeptide-1; confirm the specific grade and intended use against market requirements.
• EU cosmetics rules under Regulation (EC) No 1223/2009 require an assessment of the safety of the final cosmetic containing Palmitoyl Tripeptide-1 before the cosmetic is placed on the EU market.
• Use the supplier TDS to confirm grade-specific details for Palmitoyl Tripeptide-1 and review the destination market's requirements.

5. Sécurité et évaluation des risques

Use the stated level as reference guidance for cosmetic formulation; this reference is not approval for drug use or OTC marketing with patch and stability testing still needed for the completed formula.

6. Stabilité et conditionnement

Protect the sealed bulk from heat, sun, and unnecessary exposure; match the pack choice to the system's oxidation risk; check the finished formula and its packaging together.

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

1. INCI et CAS

INCI: Bakuchiol · CAS: 10309-37-2

2. Rôle dans la formule

Bakuchiol is a meroterpene phenol used around 0.5–1% in cosmetic leave-ons. Do not call it vitamin A or a drug retinoid.

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

• The formulation record indicates 0.5–1% for serums and creams for the formula.

Oil-soluble. Add in cool-down and protect from light.

4. Sources réglementaires et conformité mondiale

• The CosIng record for Bakuchiol, where listed, is informational rather than product-specific authorization.

• Verify the purchased Bakuchiol grade using supplier data, alongside the applicable filing rules for the destination market.

5. Sécurité et évaluation des risques

Use the stated level as reference guidance for cosmetic formulation; it does not establish drug approval or OTC-monograph status and the completed formula still requires stability and patch testing.

6. Stabilité et conditionnement

Keep the ingredient in cool, closed bulk storage away from sunlight; select packaging with the formula's oxidation sensitivity in mind; test the selected package with the confirmed batch for stability and fit.

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

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

• The guide range for gels and serums is 3–8% for the formula.
• 2–5% is listed for creams for the formula.
• Formulation guidance for rinse-off: 2–4% as a formulation guide.

• Confirm the actual Glycerin grade from supplier documentation and check requirements where the product will be sold.

5. Sécurité et évaluation des risques

The guide records a level for cosmetic formulation purposes; the listed level does not itself confer drug or OTC status and the completed cosmetic needs its own patch and stability checks.

6. Stabilité et conditionnement

Keep the ingredient in cool, closed bulk storage away from sunlight; match the pack choice to the system's oxidation risk; assess the confirmed formula for stability and package compatibility.

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

• The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.

• The listed information provides no basis for medical outcomes, cure language, or a product certification not supported by the available facts.
