Ceramide Comfort Cream Base — Variant 2

1. INCI & CAS

INCI: Ceramide NP · CAS: 100403-19-8

2. Role in the formula

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. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Cholesterol · CAS: 57-88-5

2. Role in the formula

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

3. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

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

3. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
