Niacinamide Tone Care Serum Base

1. INCI et CAS

INCI: Niacinamide · CAS: 98-92-0

2. Rôle dans la formule

Niacinamide is widely used in leave-on cosmetic guides around 2–5%. This is not a drug monograph claim and not a whitening drug claim.

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

• The guide range for serums is 2–5% for the formula.
• Gel-creams: 2–4% as a formulation guide.
• The formulation record indicates 2–3% for toners.

Dissolve in the water phase. Keep finished pH roughly 5–6.5 so it stays in the cosmetic range used by formulators.

4. Sources réglementaires et conformité mondiale

• If CosIng lists Niacinamide, that listing remains ingredient information; check rules for the intended market and use.
• An EU-market cosmetic under Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Niacinamide rather than for an ingredient name alone.
• Verify the purchased Niacinamide grade using supplier data, alongside the applicable filing rules for the destination market.

5. Sécurité et évaluation des risques

This formulation note gives a cosmetic-use reference level; it makes no claim of drug or OTC authorization while finished-product patch and stability testing remain necessary.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; where appropriate, assess an airless or pump pack for oxidation-sensitive systems; verify the chosen pack against the tested formula.

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

• The recorded cosmetic positioning for Niacinamide highlights niacinamide conditioning.

• The ingredient record is not evidence of a drug effect, a clinical cure, or certification status not established for the SKU.
• This reference for Niacinamide cannot verify skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

The glycerin note covers its polyol-humectant role in washes, gels, and emulsions and gives a formulation guide level.

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

• For gels and serums, the reference gives 3–8%.
• Creams: 2–5% as a formulation guide.
• For rinse-off, the reference gives 2–4% in this reference.

Add Glycerin to the water phase; no separate melt step is needed.

4. Sources réglementaires et conformité mondiale

• CosIng information about Glycerin does not itself authorize a particular grade or finished cosmetic.
• The finished-product provisions of Regulation (EC) No 1223/2009 require a safety evaluation of the product containing Glycerin as it will be marketed at the level of the finished cosmetic product.
• Confirm the received Glycerin grade against supplier documentation, then verify the intended market's filing requirements.

5. Sécurité et évaluation des risques

This entry provides guidance for cosmetic use only; the listed level does not itself confer drug or OTC status and the finished formula still needs patch and stability testing.

6. Stabilité et conditionnement

Use cool, sealed storage away from strong light for the bulk; evaluate packaging against the formula's susceptibility to oxidation; test the selected package with the confirmed batch for stability and fit.

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

• This guide frames Glycerin's cosmetic direction around humectant function.

• This formulation entry cannot verify therapeutic effects, curative outcomes, or unsupported certification statements.
• The ingredient note for Glycerin should not be used to substantiate a whitening effect, acne treatment, perspiration control, sun protection, or hair growth.

1. INCI et CAS

INCI: Propanediol · CAS: 504-63-2

2. Rôle dans la formule

Use the identity 1,3-propanediol for the listed humectant/solvent role. The guide does not call for propylene glycol.

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

• The most water chassis use-level reference is 2–8% as a formulation guide.

Incorporate Propanediol in the water phase.

4. Sources réglementaires et conformité mondiale

• If Propanediol appears in CosIng, its entry is informational and does not approve a specific grade or finished cosmetic.
• Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Propanediol as a finished-product assessment.
• Use current supplier documentation for the purchased Propanediol grade and verify applicable destination-market filings.

5. Sécurité et évaluation des risques

The stated concentration is a cosmetic-development reference; it makes no claim of drug or OTC authorization and the completed formula still requires stability and patch testing.

6. Stabilité et conditionnement

Store sealed bulk away from heat and sunlight; evaluate packaging against the formula's susceptibility to oxidation; follow with stability and packaging checks on the confirmed batch.

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

• The listed cosmetic direction for Propanediol emphasizes propanediol solvent.

• This cosmetic guide does not establish drug claims, cure claims, or a certification that is absent from the product records.
• This reference for Propanediol does not confirm a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
