Sérum visage éclat

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

The reference uses glycerin as a polyol humectant across washes, gels, and emulsions. Treat the percentage as development guidance.

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

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

The water phase is the addition point for Glycerin; a separate melt is unnecessary.

4. Sources réglementaires et conformité mondiale

• If Glycerin appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the final cosmetic with Glycerin to undergo a safety assessment as part of the finished cosmetic's safety documentation.
• Check the supplier's technical information for the Glycerin grade and confirm the relevant market filing list.

5. Sécurité et évaluation des risques

This formulation note gives a cosmetic-use reference level; it does not establish drug approval or OTC-monograph status and the final formula should undergo patch and stability assessment.

6. Stabilité et conditionnement

For bulk storage, avoid warmth and direct sun and keep the container closed; if the formula is oxidation-sensitive, an airless or pump format may be considered; use batch testing to verify stability and package compatibility.

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

• The recorded cosmetic positioning for Glycerin highlights humectant function.

• The ingredient record cannot verify claims of drug activity, a clinical cure, or an undocumented product certification.
• The documented facts for Glycerin cannot establish skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.

1. INCI et CAS

INCI: Propanediol · CAS: 504-63-2

2. Rôle dans la formule

1,3-propanediol serves as a cosmetic humectant and solvent in this guidance, distinct from propylene glycol.

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

• The level shown for most water chassis is 2–8% for the formula.

Incorporate Propanediol in the water phase.

4. Sources réglementaires et conformité mondiale

• If CosIng lists Propanediol, that listing remains ingredient information; check rules for the intended market and use.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires the final cosmetic with Propanediol to undergo a safety assessment for the completed formula, not simply for an ingredient in isolation.
• Compare the received Propanediol material with its supplier specification and review destination-market filing needs.

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 so the finished cosmetic should receive patch and stability checks.

6. Stabilité et conditionnement

Keep the ingredient in cool, closed bulk storage away from sunlight; if oxidation risk calls for it, review a pump or airless format; assess the confirmed formula for stability and package compatibility.

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

• The recorded cosmetic positioning for Propanediol highlights propanediol solvent.

• The available ingredient details does not establish claims of drug action or cure, or a product certification outside the supporting records.
• The ingredient record for Propanediol does not substantiate whitening, treatment of acne, 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 page.

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

• Serums and gels: 0.1–0.5% in this reference.
• The level shown for creams is 0.05–0.3%.

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

4. Sources réglementaires et conformité mondiale

• CosIng provides reference information for Sodium Hyaluronate; confirm the specific grade and intended use against market requirements.
• Regulation (EC) No 1223/2009 sets the requirement for a safety review of the finished cosmetic in which Sodium Hyaluronate is used as part of the finished cosmetic's safety documentation.
• Verify the purchased Sodium Hyaluronate 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 makes no claim of drug or OTC authorization and patch and stability testing remain part of finished-product review.

6. Stabilité et conditionnement

Hold the bulk material in a sealed, cool place shielded from light; consider an airless or pump format when oxidation sensitivity warrants it; then verify formula stability and pack compatibility on the confirmed batch.

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

• The listed cosmetic direction for Sodium Hyaluronate emphasizes hydration-polymer.

• This product entry cannot substantiate therapeutic results, cure claims, or unverified certification claims.
• The ingredient note for Sodium Hyaluronate does not substantiate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
