Ceramide NP

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)

• Gel-creams: 0.1–0.3% as a formulation guide.
• The richer creams use-level reference is 0.2–0.5%.

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

• Database information on Ceramide NP does not replace review of the supplied grade and finished product under market rules.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the final cosmetic with Ceramide NP to undergo a safety assessment rather than for an ingredient name alone.
• Confirm the actual Ceramide NP grade from supplier documentation and check requirements where the product will be sold.

5. Sécurité et évaluation des risques

This level is a cosmetic-formulation guide; no drug approval or OTC-monograph status follows from this guide and the finished formula still needs patch and stability testing.

6. Stabilité et conditionnement

Keep bulk material sealed, cool, and out of direct sunlight; 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)

• For cosmetic use, this entry records Ceramide NP in a direction centered on ceramide barrier-lipid.

• The ingredient guidance cannot verify therapeutic results, cure claims, or unverified certification claims.
• This reference for Ceramide NP should not be cited in support of whitening, acne treatment, antiperspirant action, sunscreen use, or hair-growth outcomes.

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)

• Gel-creams: 0.1–0.3% as a formulation guide.
• For richer creams, the reference gives 0.2–0.5% for the formula.

Melt with the ceramide phase and cool under controlled shear.

4. Sources réglementaires et conformité mondiale

• A CosIng listing for Cholesterol provides ingredient information, not approval of a supplied grade or finished product.
• The framework in Regulation (EC) No 1223/2009 requires the completed product containing Cholesterol to receive its own safety assessment before the cosmetic is placed on the EU market.
• For Cholesterol, check the purchased grade against its supplier TDS and review filing requirements in the destination market.

5. Sécurité et évaluation des risques

This level is a cosmetic-formulation guide; 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 the sealed bulk from heat, sun, and unnecessary exposure; 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)

• The listed cosmetic direction for Cholesterol emphasizes lamellar co-lipid.

• This formulation entry does not support a drug effect, a clinical cure, or certification status not established for the SKU.
• The cosmetic guidance for Cholesterol does not substantiate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

In cosmetic gels, emulsions, and washes, glycerin functions as a polyol humectant; its listed level is a guide.

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

• The gels and serums use-level reference is 3–8% as a formulation guide.
• The creams use-level reference is 2–5%.
• The level shown for rinse-off is 2–4% for the formula.

Use the water phase to introduce Glycerin; no melting stage is required.

4. Sources réglementaires et conformité mondiale

• If CosIng lists Glycerin, that listing remains ingredient information; check rules for the intended market and use.
• Before EU placement, Regulation (EC) No 1223/2009 requires the complete cosmetic containing Glycerin to receive its own safety assessment rather than for an ingredient name alone.
• For Glycerin, check the purchased grade against its supplier TDS and review filing requirements in the destination market.

5. Sécurité et évaluation des risques

The stated concentration is a cosmetic-development reference; it is not evidence of drug approval or OTC authorization with patch and stability testing still needed for the completed formula.

6. Stabilité et conditionnement

Store the bulk in a closed container in a cool, shaded place; 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 cosmetic concept for Glycerin in this entry centers on humectant function.

• This product entry does not substantiate a drug effect, a clinical cure, or certification status not established for the SKU.
• The Glycerin entry does not support whitening, acne treatment, antiperspirant action, sunscreen use, or hair-growth outcomes.
