Base de crème confort aux céramides — variante 2

1. INCI et CAS

INCI: Ceramide NP · CAS: 100403-19-8

2. Rôle dans la formule

Ceramide NP is the primary sphingolipid in a multi-ceramide guide. It is paired here with cholesterol as a lamellar co-lipid. Levels are guides, not a skin-identical drug claim.

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

• For gel-creams, the recorded level is 0.1–0.3% in this reference.
• For richer creams, the reference gives 0.2–0.5% for the formula.

Introduce from a pre-dispersed lipid concentrate or a warm oil phase. Avoid long holds at high heat after the lipids melt.

4. Sources réglementaires et conformité mondiale

• A CosIng listing for Ceramide NP provides ingredient information, not approval of a supplied grade or finished product.
• Regulation (EC) No 1223/2009 sets the requirement for an assessment of the safety of the final cosmetic containing Ceramide NP as part of the finished cosmetic's safety documentation.
• Compare the received Ceramide NP material with its supplier specification and review destination-market filing needs.

5. Sécurité et évaluation des risques

Use the stated level as reference guidance for cosmetic formulation; it does not establish drug approval or OTC-monograph status while finished-product patch and stability testing remain necessary.

6. Stabilité et conditionnement

Hold the bulk material in a sealed, cool place shielded from light; take oxidation sensitivity into account when selecting the final pack; verify the chosen pack against the tested formula.

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

• The formulation note describes Ceramide NP as part of a cosmetic direction focused on ceramide barrier-lipid.

• The cosmetic listing does not demonstrate a drug effect, a clinical cure, or certification status not established for the SKU.
• The available details for Ceramide NP does not support skin whitening, acne treatment, antiperspirant use, sun protection, or hair growth.

1. INCI et CAS

INCI: Cholesterol · CAS: 57-88-5

2. Rôle dans la formule

Cholesterol is the sterol co-lipid used with ceramides in barrier emulsions. This is a cosmetic lipid, not a serum-cholesterol claim.

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

• For gel-creams, the recorded level is 0.1–0.3%.
• For richer creams, the recorded level is 0.2–0.5% as a formulation guide.

Melt with the ceramide phase and cool under controlled shear.

4. Sources réglementaires et conformité mondiale

• CosIng provides reference information for Cholesterol; confirm the specific grade and intended use against market requirements.
• For a cosmetic sold in the EU, Regulation (EC) No 1223/2009 requires an assessment of the safety of the final cosmetic containing Cholesterol as a finished-product assessment.
• Check the supplier's technical information for the Cholesterol grade and confirm the relevant market filing list.

5. Sécurité et évaluation des risques

The guide records a level for cosmetic formulation purposes; it does not authorize a drug or OTC product while finished-product patch and stability testing remain necessary.

6. Stabilité et conditionnement

Use cool, sealed storage away from strong light for the bulk; select packaging with the formula's oxidation sensitivity in mind; use batch testing to verify stability and package compatibility.

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

• This guide frames Cholesterol's cosmetic direction around lamellar co-lipid.

• The ingredient record is not evidence of therapeutic effects, curative outcomes, or unsupported certification statements.
• This reference for Cholesterol does not substantiate whitening, acne care as treatment, perspiration reduction, sun protection, or hair growth.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

Glycerin serves as the polyol humectant in these cosmetic formats, while the stated percentage remains a formulation reference.

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

• The formulation record indicates 3–8% for gels and serums in this reference.
• 2–5% is listed for creams as a formulation guide.
• The rinse-off use-level reference is 2–4% as a formulation guide.

Add Glycerin to the water phase; no separate melt step is needed.

4. Sources réglementaires et conformité mondiale

• A CosIng entry naming Glycerin does not by itself approve the purchased grade or complete cosmetic.
• The framework in Regulation (EC) No 1223/2009 requires a safety assessment of the finished cosmetic containing Glycerin for the complete formula intended for sale.
• Establish grade-specific details for Glycerin from the supplier and assess filing requirements in the intended market.

5. Sécurité et évaluation des risques

Use the stated level as reference guidance for cosmetic formulation; it is not evidence of drug approval or OTC authorization so patch response and stability should be checked on the finished product.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; where oxidation is a concern, evaluate airless or pump packaging; test the selected package with the confirmed batch for stability and fit.

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

• The recorded cosmetic positioning for Glycerin highlights humectant function.

• The development record cannot verify claims of drug action or cure, or a product certification outside the supporting records.
• The documented facts for Glycerin cannot establish a skin-lightening result, acne treatment, antiperspirant action, sunscreen efficacy, or hair growth.
