Ceramide NP

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)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & 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)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

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

3. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
