Dark Spot Care Serum Base

1. INCI & CAS

INCI: Alpha-Arbutin · CAS: 84380-01-8

2. Role in the formula

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. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

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

2. Role in the formula

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

3. Typical use levels (formulation guide)

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

Dissolve into the water phase.

4. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

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

3. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
• The formulation record for Glycerin cannot establish skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.
