Dark Spot Care Serum Base

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)

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

For dissolution, use 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 an assessment of the safety of the final cosmetic containing Alpha-Arbutin rather than for an ingredient name alone.
• Use the supplier TDS to confirm grade-specific details for Alpha-Arbutin and review the destination market's requirements.

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 cosmetic needs its own patch and stability checks.

6. Stabilité et conditionnement

For bulk storage, avoid warmth and direct sun and keep the container closed; for oxidation-sensitive formulas, consider an airless or pump pack; follow with stability and packaging checks on the confirmed batch.

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

• The recorded cosmetic positioning for Alpha-Arbutin highlights alpha-arbutin tone-care.

• This product entry does not establish therapeutic effects, curative outcomes, or unsupported certification statements.
• The ingredient record for Alpha-Arbutin does not establish a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.

1. INCI et CAS

INCI: Dipotassium Glycyrrhizate · CAS: 68797-35-3

2. Rôle dans la formule

Dipotassium glycyrrhizate is the water-soluble salt of glycyrrhizic acid. The guide does not claim a drug anti-inflammatory effect.

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

• Formulation guidance for serums and creams: 0.1–0.5% for the formula.

Dissolve into the water phase.

4. Sources réglementaires et conformité mondiale

• If CosIng lists Dipotassium Glycyrrhizate, that listing remains ingredient information; check rules for the intended market and use.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Dipotassium Glycyrrhizate at the level of the finished cosmetic product.
• Use the supplier TDS to confirm grade-specific details for Dipotassium Glycyrrhizate and review the destination market's 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 and the final formula should undergo patch and stability assessment.

6. Stabilité et conditionnement

Use cool, sealed storage away from strong light for the bulk; for oxidation-sensitive formulas, consider an airless or pump pack; check the finished batch's stability and package compatibility.

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

• The formulation note describes Dipotassium Glycyrrhizate as part of a cosmetic direction focused on licorice-salt comfort.

• This formulation entry provides no basis for therapeutic effects, curative outcomes, or unsupported certification statements.
• This reference for Dipotassium Glycyrrhizate cannot verify whitening, acne treatment, antiperspirant action, sunscreen use, or hair-growth outcomes.

1. INCI et CAS

INCI: Glycerin · CAS: 56-81-5

2. Rôle dans la formule

Glycerin is a polyol humectant used in cosmetic emulsions, gels, and washes. The percentage shown is formulation guidance.

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

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

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

4. Sources réglementaires et conformité mondiale

• CosIng provides reference information for Glycerin; confirm the specific grade and intended use against market requirements.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the completed product containing Glycerin to receive its own safety assessment before the cosmetic is placed on the EU market.
• Confirm the actual Glycerin grade from supplier documentation and check requirements where the product will be sold.

5. Sécurité et évaluation des risques

Read the recorded level as a cosmetic formulation guide; no drug approval or OTC-monograph status follows from this guide and patch and stability testing remain part of finished-product review.

6. Stabilité et conditionnement

Protect the sealed bulk from heat, sun, and unnecessary exposure; for oxidation-sensitive formulas, consider an airless or pump pack; test the selected package with the confirmed batch for stability and fit.

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

• The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.

• The development record does not support therapeutic results, cure claims, or unverified certification claims.
