daily barrier lotion base (variant 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)

• The guide range for gel-creams is 0.1–0.3% in this reference.
• Richer creams may use the guide range 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

• CosIng information about Ceramide NP does not itself authorize a particular grade or finished cosmetic.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires a safety review of the finished cosmetic in which Ceramide NP is used before the finished product is marketed.
• Review the documentation for the actual Ceramide NP grade and the filing requirements for the target market.

5. Sécurité et évaluation des risques

The use-level note is a reference for cosmetic formulation; this reference is not approval for drug use or OTC marketing with patch response and finished-product stability still to be verified.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; choose a package with oxidation sensitivity in view; check the finished formula and its packaging together.

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.

• This reference does not demonstrate therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• This guide to Ceramide NP cannot verify whitening, acne care as treatment, perspiration reduction, 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)

• Formulation guidance for gel-creams: 0.1–0.3%.
• The level shown for richer creams is 0.2–0.5%.

Melt with the ceramide phase and cool under controlled shear.

4. Sources réglementaires et conformité mondiale

• A CosIng entry naming Cholesterol does not by itself approve the purchased grade or complete cosmetic.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires an assessment of the safety of the final cosmetic containing Cholesterol before the finished product is marketed.
• Use current supplier documentation for the purchased Cholesterol grade and verify applicable destination-market filings.

5. Sécurité et évaluation des risques

The listed use rate is intended as a cosmetic-development guide; it makes no claim of drug or OTC authorization so assess patch response and stability in the final formula.

6. Stabilité et conditionnement

Keep the bulk container closed and shaded in a cool area; select packaging with the formula's oxidation sensitivity in mind; verify the chosen pack against the tested formula.

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

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

• The development record does not establish claims of drug activity, a clinical cure, or an undocumented product certification.
• This reference for Cholesterol does not support whitening, treatment of acne, perspiration control, sun protection, or hair growth.

1. INCI et CAS

INCI: Panthenol · CAS: 81-13-0

2. Rôle dans la formule

The reference describes D-panthenol as a water-soluble humectant for serums, gels, lotions, and washes. Its level is not a batch test result.

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

• For serums and gels, the recorded level is 1–5%.
• For creams and lotions, the recorded level is 1–3% as a formulation guide.
• The formulation record indicates 0.5–2% for rinse-off washes for the formula.

This water-soluble Panthenol is added in cool-down; the noted typical leave-on pH is about 5–6.

4. Sources réglementaires et conformité mondiale

• Use CosIng's information on Panthenol as a reference, then verify the specific grade and intended use under market rules.
• EU market placement under Regulation (EC) No 1223/2009 requires a product-level safety assessment for the complete formula that contains Panthenol for the complete formula intended for sale.
• Use current supplier documentation for the purchased Panthenol grade and verify applicable destination-market filings.

5. Sécurité et évaluation des risques

This formulation note gives a cosmetic-use reference level; no drug approval or OTC-monograph status follows from this guide so the finished cosmetic should receive patch and stability checks.

6. Stabilité et conditionnement

Use cool, sealed storage away from strong light for the bulk; review airless or pump options if oxidation presents a concern; use batch testing to verify stability and package compatibility.

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

• The cosmetic concept for Panthenol in this entry centers on comfort and humectant support.

• This product entry cannot verify drug effects, cures, or certification claims that go beyond the documented ingredient information.
• The cosmetic guidance for Panthenol cannot verify a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
