Vitamin C

1. INCI et CAS

INCI: 3-O-Ethyl Ascorbic Acid · CAS: 86404-04-8

2. Rôle dans la formule

3-O-ethyl ascorbic acid is used in cosmetic serum guides. It is not a drug and not a measured brightening percentage.

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

• For serums, the reference gives 1–3% as a formulation guide.
• 0.5–2% is listed for gel-creams as a formulation guide.

For dissolution, use water. Keep the bulk cool and protected from light.

4. Sources réglementaires et conformité mondiale

• An entry for 3-O-Ethyl Ascorbic Acid in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• For an EU-market product, Regulation (EC) No 1223/2009 requires an assessment of the safety of the final cosmetic containing 3-O-Ethyl Ascorbic Acid in the final product context.
• Confirm the actual 3-O-Ethyl Ascorbic Acid grade from supplier documentation and check requirements where the product will be sold.

5. Sécurité et évaluation des risques

Treat the listed amount as cosmetic-development guidance; it is not evidence of drug approval or OTC authorization and the completed formula still requires stability and patch testing.

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; then verify formula stability and pack compatibility on the confirmed batch.

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

• The listed cosmetic direction for 3-O-Ethyl Ascorbic Acid emphasizes ethylated vitamin C.

• The cosmetic listing does not support drug effects, clinical cures, or unsupported product certifications.
• The cosmetic guidance for 3-O-Ethyl Ascorbic Acid does not substantiate whitening, treatment of acne, perspiration control, sun protection, or hair growth.

1. INCI et CAS

INCI: Ferulic Acid · CAS: 1135-24-6

2. Rôle dans la formule

Ferulic acid is poorly water-soluble and is used at low cosmetic levels. It is not a drug.

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

• The stated reference for serums is 0.3–0.5% with a suitable solvent.

Pre-dissolve. Low pH and light both matter; follow the TDS.

4. Sources réglementaires et conformité mondiale

• CosIng may identify Ferulic Acid as an ingredient, but its entry does not approve a material grade or finished formula.
• The framework in Regulation (EC) No 1223/2009 requires the finished product's safety, including the formula in which Ferulic Acid is used, to be assessed before the finished product is marketed.
• Check the supplier's technical information for the Ferulic Acid grade and confirm the relevant market filing list.

5. Sécurité et évaluation des risques

The concentration shown is guidance for cosmetic formulation; the listed level does not itself confer drug or OTC status so patch response and stability should be checked on the finished product.

6. Stabilité et conditionnement

Keep the bulk container closed and shaded in a cool area; take oxidation sensitivity into account when selecting the final pack; assess the confirmed formula for stability and package compatibility.

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

• The cosmetic formulation concept for Ferulic Acid centers on ferulic antioxidant.

• This ingredient reference cannot substantiate drug effects, cures, or certification claims that go beyond the documented ingredient information.
• This reference for Ferulic Acid offers no support for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

Cosmetic washes, gels, and emulsions use glycerin in a polyol-humectant role; the listed level is for formulation development.

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

• Formulation guidance for gels and serums: 3–8%.
• The stated reference for creams is 2–5%.
• Formulation guidance for rinse-off: 2–4% as a formulation guide.

Incorporate Glycerin in the water phase without a separate melt step.

4. Sources réglementaires et conformité mondiale

• Use CosIng's information on Glycerin as a reference, then verify the specific grade and intended use under market rules.
• The finished-product provisions of Regulation (EC) No 1223/2009 require a safety review of the finished cosmetic in which Glycerin is used before release of the finished cosmetic.
• Confirm the received Glycerin grade against supplier documentation, then verify the intended market's filing requirements.

5. Sécurité et évaluation des risques

The use-level note is a reference for cosmetic formulation; it does not qualify a finished product as a drug or OTC product so assess patch response and stability in the final formula.

6. Stabilité et conditionnement

Store sealed bulk away from heat and sunlight; consider an airless or pump format when oxidation sensitivity warrants it; check the final package and formula together for compatibility and stability.

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

• The cosmetic formulation concept for Glycerin centers on humectant function.

• The ingredient record does not demonstrate claims of drug action or cure, or a product certification outside the supporting records.
• This reference for Glycerin offers no support for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
