daily barrier lotion 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)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & 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)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Panthenol · CAS: 81-13-0

2. Role in the formula

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. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
