firming and smoothing serum

1. INCI & CAS

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

2. Role in the formula

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. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• The cosmetic concept for Palmitoyl Tripeptide-1 in this entry centers on peptide firming.

• This reference does not substantiate drug-treatment outcomes, clinical cures, or certifications not documented for the SKU.
• The cosmetic guidance for Palmitoyl Tripeptide-1 cannot establish whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI & CAS

INCI: Bakuchiol · CAS: 10309-37-2

2. Role in the formula

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. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• The CosIng record for Bakuchiol, where listed, is informational rather than product-specific authorization.
• The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment of the finished cosmetic containing Bakuchiol rather than for an ingredient name alone.
• Verify the purchased Bakuchiol grade using supplier data, alongside the applicable filing rules for the destination market.

5. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• This guide frames Bakuchiol's cosmetic direction around bakuchiol.

• The formulation note provides no basis for drug effects, clinical cures, or unsupported product certifications.
• The formulation record for Bakuchiol does not demonstrate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

The listed glycerin role is that of a polyol humectant in cosmetic washes, gels, and emulsions; the amount is guidance only.

3. Typical use levels (formulation guide)

• 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.

Add Glycerin in the water phase without melting it first.

4. Regulatory sources & global compliance

• CosIng provides reference information for Glycerin; confirm the specific grade and intended use against market requirements.
• An EU-market cosmetic under Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Glycerin before the cosmetic is placed on the EU market.
• Confirm the actual Glycerin grade from supplier documentation and check requirements where the product will be sold.

5. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
• This cosmetic entry naming Glycerin provides no basis for skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.
