Sérum hydratant pour le visage

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

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

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

• 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. Sources réglementaires et conformité mondiale

• 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. Sécurité et évaluation des risques

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. Stabilité et conditionnement

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

• 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 et CAS

INCI: Propanediol · CAS: 504-63-2

2. Rôle dans la formule

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

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

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

Add Propanediol to the water phase.

4. Sources réglementaires et conformité mondiale

• 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. Sécurité et évaluation des risques

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. Stabilité et conditionnement

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

• 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 et CAS

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

2. Rôle dans la formule

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. Niveaux d'emploi typiques (repère de formulation)

• 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. Sources réglementaires et conformité mondiale

• 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. 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 assessment and finished-formula stability testing still required.

6. Stabilité et conditionnement

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

• 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.
