Base de sérum à l’alpha-arbutine

1. INCI et CAS

INCI: Alpha-Arbutin · CAS: 84380-01-8

2. Rôle dans la formule

Alpha-arbutin is the alpha anomer used in cosmetic tone-care guides, commonly around 0.5–2%. Do not describe it as hydroquinone and do not claim medical depigmentation.

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

• Formulation guidance for serums: 1–2% as a formulation guide.
• Formulation guidance for creams: 0.5–2% for the formula.

Dissolve into water. Prefer mildly acid to neutral pH and limit prolonged high heat.

4. Sources réglementaires et conformité mondiale

• CosIng may identify Alpha-Arbutin as an ingredient, but its entry does not approve a material grade or finished formula.
• The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment of the complete cosmetic formula containing Alpha-Arbutin before release of the finished cosmetic.
• Confirm the received Alpha-Arbutin grade against supplier documentation, then verify the intended market's filing requirements.

5. Sécurité et évaluation des risques

The listed use rate is intended as a cosmetic-development guide; it is not evidence of drug approval or OTC authorization and the completed cosmetic needs its own patch and stability checks.

6. Stabilité et conditionnement

Keep bulk supplies closed, cool, and protected from sunlight; take oxidation sensitivity into account when selecting the final pack; check the final package and formula together for compatibility and stability.

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

• This guide frames Alpha-Arbutin's cosmetic direction around alpha-arbutin tone-care.

• The formulation note does not substantiate claims of drug activity, a clinical cure, or an undocumented product certification.
• The Alpha-Arbutin entry cannot establish skin whitening, acne treatment, antiperspirant use, sun protection, or hair growth.

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)

• The formulation record indicates 3–8% for gels and serums.
• 2–5% is listed for creams for the formula.
• The rinse-off use-level reference is 2–4%.

Add Glycerin in the water phase without melting it first.

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 rather than for an ingredient name alone.
• Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.

5. Sécurité et évaluation des risques

Use the stated level as reference guidance for cosmetic formulation; it provides no evidence that a drug or OTC monograph applies with patch and stability testing still needed for the completed formula.

6. Stabilité et conditionnement

Store sealed bulk away from heat and sunlight; consider an airless or pump format when oxidation sensitivity warrants it; confirm compatibility and stability using the selected formula and pack.

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

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

• The ingredient guidance provides no basis for claims of drug action or cure, or a product certification outside the supporting records.
• This guide to Glycerin does not support whitening, acne care as treatment, perspiration reduction, sun protection, or hair growth.

1. INCI et CAS

INCI: Propanediol · CAS: 504-63-2

2. Rôle dans la formule

For cosmetic formulation, 1,3-propanediol is identified as a humectant and solvent, not as propylene glycol.

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

• The guide range for most water chassis is 2–8% for the formula.

The water phase is the addition point for Propanediol.

4. Sources réglementaires et conformité mondiale

• Database information on Propanediol does not replace review of the supplied grade and finished product under market rules.
• For a cosmetic sold in the EU, Regulation (EC) No 1223/2009 requires the complete cosmetic containing Propanediol to receive its own safety assessment in the final product context.
• Match the selected Propanediol material to its supplier TDS and check the filing list for the market of sale.

5. Sécurité et évaluation des risques

This entry provides guidance for cosmetic use only; the note establishes neither drug approval nor OTC-monograph status so the finished cosmetic should receive patch and stability checks.

6. Stabilité et conditionnement

Keep bulk material sealed, cool, and out of direct sunlight; where oxidation is a concern, evaluate airless or pump packaging; check the finished formula and its packaging together.

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

• The recorded cosmetic positioning for Propanediol highlights propanediol solvent.

• The cosmetic listing is not evidence of medical outcomes, cure language, or a product certification not supported by the available facts.
• The ingredient record for Propanediol offers no support for a skin-lightening result, acne treatment, antiperspirant action, sunscreen efficacy, or hair growth.
