Calming Face Serum

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

Cosmetic washes, gels, and emulsions use glycerin in a polyol-humectant role; the listed level is for formulation development.

3. Typical use levels (formulation guide)

• The level shown for gels and serums is 3–8% in this reference.
• The level shown for creams is 2–5% as a formulation guide.
• For rinse-off, use 2–4% for the formula.

Incorporate Glycerin in the water phase without a separate melt step.

4. Regulatory sources & global compliance

• An entry for Glycerin in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• Regulation (EC) No 1223/2009 requires an assessment addressing the safety of the finished product that contains Glycerin for the complete formula intended for sale.
• Use the supplier TDS to confirm grade-specific details for Glycerin and review the destination market's requirements.

5. Safety & risk assessment

The listed use rate is intended as a cosmetic-development guide; no drug approval or OTC-monograph status follows from this guide and the finished formula still needs patch and stability testing.

6. Stability & packaging

Hold the bulk material in a sealed, cool place shielded from light; 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)

• The listed cosmetic direction for Glycerin emphasizes humectant function.

• The listed information cannot substantiate drug claims, cure claims, or a certification that is absent from the product records.
• The information about Glycerin does not establish skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.

1. INCI & CAS

INCI: Propanediol · CAS: 504-63-2

2. Role in the formula

This cosmetic-formulation note assigns 1,3-propanediol humectant and solvent functions; the ingredient is not propylene glycol.

3. Typical use levels (formulation guide)

• Formulation guidance for most water chassis: 2–8% for the formula.

Add Propanediol to the water phase.

4. Regulatory sources & global compliance

• Use CosIng's information on Propanediol as a reference, then verify the specific grade and intended use under market rules.
• The framework in Regulation (EC) No 1223/2009 requires the final cosmetic with Propanediol to undergo a safety assessment for the complete formula intended for sale.
• Match the selected Propanediol material to its supplier TDS and check the filing list for the market of sale.

5. Safety & risk assessment

The use-level note is a reference for cosmetic formulation; the listed level does not itself confer drug or OTC status with patch and stability testing still needed for the completed formula.

6. Stability & packaging

Protect sealed bulk from warmth and direct light; for oxidation-sensitive formulas, consider an airless or pump pack; test the selected package with the confirmed batch for stability and fit.

7. Claims language (Do / Don’t)

• The cosmetic concept for Propanediol in this entry centers on propanediol solvent.

• The development record does not demonstrate medical outcomes, cure language, or a product certification not supported by the available facts.
• The Propanediol entry is not evidence for a whitening effect, acne treatment, perspiration control, sun protection, or hair growth.

1. INCI & CAS

INCI: Sodium Hyaluronate · CAS: 9067-32-7

2. Role in the formula

Sodium hyaluronate is the salt form used in cosmetic gels and serums. Molecular weight is a supplier choice and is not fixed on this entry.

3. Typical use levels (formulation guide)

• For serums and gels, the reference gives 0.1–0.5% in this reference.
• The stated reference for creams is 0.05–0.3% as a formulation guide.

Hydrate in water before gum. Avoid dumping powder onto a finished thick gel.

4. Regulatory sources & global compliance

• Use CosIng's information on Sodium Hyaluronate as a reference, then verify the specific grade and intended use under market rules.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires the finished product's safety, including the formula in which Sodium Hyaluronate is used, to be assessed for the completed formula, not simply for an ingredient in isolation.
• Review the documentation for the actual Sodium Hyaluronate grade and the filing requirements for the target market.

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 assessment and finished-formula stability testing still required.

6. Stability & packaging

Protect sealed bulk from warmth and direct light; where appropriate, assess an airless or pump pack for oxidation-sensitive systems; check the finished formula and its packaging together.

7. Claims language (Do / Don’t)

• The recorded cosmetic positioning for Sodium Hyaluronate highlights hydration-polymer.

• This ingredient reference does not support drug-treatment outcomes, clinical cures, or certifications not documented for the SKU.
• The documented facts for Sodium Hyaluronate offers no support for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
