Base de crème confort aux céramides

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)

• The gel-creams use-level reference is 0.1–0.3% in this reference.
• Formulation guidance for richer creams: 0.2–0.5% as a formulation guide.

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

• CosIng provides reference information for Ceramide NP; confirm the specific grade and intended use against market requirements.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires a product-level safety assessment for the complete formula that contains Ceramide NP for the product in its final form.
• Compare the received Ceramide NP material with its supplier specification and review destination-market filing needs.

5. Sécurité et évaluation des risques

The stated concentration is a cosmetic-development reference; it makes no claim of drug or OTC authorization with patch assessment and finished-formula stability testing still required.

6. Stabilité et conditionnement

Protect the sealed bulk from heat, sun, and unnecessary exposure; choose a package with oxidation sensitivity in view; use batch testing to verify stability and package compatibility.

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

• The cosmetic concept for Ceramide NP in this entry centers on ceramide barrier-lipid.

• The development record cannot substantiate claims of drug activity, a clinical cure, or an undocumented product certification.
• This reference for Ceramide NP cannot verify whitening effects, acne treatment, antiperspirant performance, sunscreen 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)

• The stated reference for gel-creams is 0.1–0.3% for the formula.
• The guide range for richer creams is 0.2–0.5% in this reference.

Melt with the ceramide phase and cool under controlled shear.

4. Sources réglementaires et conformité mondiale

• If Cholesterol appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires the final cosmetic with Cholesterol to undergo a safety assessment for the specific product as it will be marketed.
• Review the documentation for the actual Cholesterol grade and the filing requirements for the target market.

5. Sécurité et évaluation des risques

Read the recorded level as a cosmetic formulation guide; it is not evidence of drug approval or OTC authorization and the completed cosmetic needs its own patch and stability checks.

6. Stabilité et conditionnement

Protect the sealed bulk from heat, sun, and unnecessary exposure; if the formula is oxidation-sensitive, an airless or pump format may be considered; 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 Cholesterol highlights lamellar co-lipid.

• The ingredient guidance cannot substantiate therapeutic results, cure claims, or unverified certification claims.
• The ingredient record for Cholesterol is not evidence for skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

As a polyol humectant, glycerin is used in cosmetic emulsions, gels, and washes. The recorded percentage is not a measured batch value.

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

• The level shown for gels and serums is 3–8% for the formula.
• The guide range for creams is 2–5% in this reference.
• 2–4% is listed for rinse-off for the formula.

Incorporate Glycerin in the water phase without a separate melt step.

4. Sources réglementaires et conformité mondiale

• Treat any CosIng entry for Glycerin as a reference only; verify the grade and intended use under current market rules.
• An EU-market cosmetic under Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Glycerin for the completed formula, not simply for an ingredient in isolation.
• 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 guide records a level for cosmetic formulation purposes; it does not qualify a finished product as a drug or OTC product and the completed cosmetic needs its own patch and stability checks.

6. Stabilité et conditionnement

Maintain cool, closed, light-protected storage for the bulk material; if the formula is oxidation-sensitive, an airless or pump format may be considered; verify the chosen pack against the tested formula.

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

• The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.

• This ingredient reference does not establish therapeutic effects, curative outcomes, or unsupported certification statements.
• The documented facts for Glycerin cannot verify whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
