Hyaluronic Serum Base

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)

• Formulation guidance for serums and gels: 0.1–0.5% in this reference.
• Creams may use the guide range 0.05–0.3%.

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

4. Sources réglementaires et conformité mondiale

• CosIng information about Sodium Hyaluronate does not itself authorize a particular grade or finished cosmetic.
• Before EU placement, Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Sodium Hyaluronate before release of the finished cosmetic.
• Confirm the actual Sodium Hyaluronate 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; it makes no claim of drug or OTC authorization and the finished formula still needs patch and stability testing.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; select packaging with the formula's oxidation sensitivity in mind; confirm final stability and pack compatibility on a representative batch.

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

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

• The ingredient record provides no basis for therapeutic effects, curative outcomes, or unsupported certification statements.
• This cosmetic entry naming Sodium Hyaluronate is not evidence for a skin-lightening result, acne treatment, antiperspirant action, sunscreen efficacy, or hair growth.

1. INCI et CAS

INCI: Panthenol · CAS: 81-13-0

2. Rôle dans la formule

Across serums, gels, lotions, and washes, D-panthenol serves as a water-soluble humectant; the percentage is guidance rather than an assay.

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

• The level shown for serums and gels is 1–5% in this reference.
• Creams and lotions: 1–3% for the formula.
• For rinse-off washes, the reference gives 0.5–2% as a formulation guide.

Panthenol is water-soluble and should be added in cool-down; a typical leave-on pH is about 5–6.

4. Sources réglementaires et conformité mondiale

• A CosIng listing for Panthenol provides ingredient information, not approval of a supplied grade or finished product.
• For an EU-market product, Regulation (EC) No 1223/2009 requires the finished product's safety, including the formula in which Panthenol is used, to be assessed rather than for an ingredient name alone.
• Compare the received Panthenol material with its supplier specification and review destination-market filing needs.

5. Sécurité et évaluation des risques

This entry provides guidance for cosmetic use only; no drug approval or OTC-monograph status follows from this guide with patch and stability testing still needed for the completed formula.

6. Stabilité et conditionnement

Protect sealed bulk from warmth and direct light; take oxidation sensitivity into account when selecting the final pack; confirm compatibility and stability using the selected formula and pack.

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

• The cosmetic formulation concept for Panthenol centers on comfort and humectant support.

• The development record does not substantiate therapeutic effects, curative outcomes, or unsupported certification statements.
• The Panthenol entry cannot establish whitening, treatment of acne, perspiration control, sun protection, or hair growth.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

Glycerin fills a polyol-humectant role in the listed cosmetic formats. Read its percentage as formulation guidance, not an assay.

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

• For gels and serums, the reference gives 3–8% as a formulation guide.
• The guide range for creams is 2–5% as a formulation guide.
• Rinse-off: 2–4%.

The guide places Glycerin in the water phase and calls for no melt step.

4. Sources réglementaires et conformité mondiale

• CosIng provides reference information for Glycerin; confirm the specific grade and intended use against market requirements.
• The framework in Regulation (EC) No 1223/2009 requires a product-level safety assessment for the complete formula that contains Glycerin at the level of the finished cosmetic product.
• Confirm the received Glycerin grade against supplier documentation, then verify the intended market's filing requirements.

5. Sécurité et évaluation des risques

The guide records a level for cosmetic formulation purposes; it provides no evidence that a drug or OTC monograph applies and the final formula should undergo patch and stability assessment.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; choose a package with oxidation sensitivity in view; follow with stability and packaging checks on the confirmed batch.

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

• The cosmetic role of Glycerin is presented as humectant function.

• This formulation entry provides no basis for claims of drug action or cure, or a product certification outside the supporting records.
• The Glycerin entry should not be used to substantiate skin whitening, acne treatment, antiperspirant use, sun protection, or hair growth.
