Hyaluronic Serum Base

1. INCI e CAS

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

2. Ruolo nella 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 page.

3. Livelli d'uso tipici (guida di formulazione)

• 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. Fonti normative e conformità globale

• 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. Sicurezza e valutazione del rischio

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. Stabilità e packaging

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. Linguaggio dei claim (cosa dire / cosa non dire)

• 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 e CAS

INCI: Panthenol · CAS: 81-13-0

2. Ruolo nella formula

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

3. Livelli d'uso tipici (guida di formulazione)

• 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. Fonti normative e conformità globale

• 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. Sicurezza e valutazione del rischio

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. Stabilità e packaging

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. Linguaggio dei claim (cosa dire / cosa non dire)

• 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 e CAS

INCI: Glycerin · CAS: 56-81-5

2. Ruolo nella formula

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

3. Livelli d'uso tipici (guida di formulazione)

• 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. Fonti normative e conformità globale

• 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. Sicurezza e valutazione del rischio

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. Stabilità e packaging

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. Linguaggio dei claim (cosa dire / cosa non dire)

• 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.
