dark spot care serum

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 recorded level is 1–2% in this reference.
• For creams, the reference gives 0.5–2% for the formula.

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

4. Regulatory sources & global compliance

• CosIng provides reference information for Alpha-Arbutin; confirm the specific grade and intended use against market requirements.
• EU market placement under Regulation (EC) No 1223/2009 requires an assessment addressing the safety of the finished product that contains Alpha-Arbutin as a finished-product assessment.
• Establish grade-specific details for Alpha-Arbutin from the supplier and assess filing requirements in the intended market.

5. Safety & risk assessment

The stated concentration is a cosmetic-development reference; no drug approval or OTC status is conferred by this entry with patch and stability testing still needed for the completed formula.

6. Stability & packaging

Store sealed bulk away from heat and sunlight; match the pack choice to the system's oxidation risk; confirm final stability and pack compatibility on a representative batch.

7. Claims language (Do / Don’t)

• For cosmetic use, this entry records Alpha-Arbutin in a direction centered on alpha-arbutin tone-care.

• The development record does not establish drug effects, cures, or certification claims that go beyond the documented ingredient information.
• The ingredient note for Alpha-Arbutin does not establish skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.

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)

• The serums and creams use-level reference is 0.1–0.5%.

Dissolve in the water phase.

4. Regulatory sources & global compliance

• A CosIng entry naming Dipotassium Glycyrrhizate does not by itself approve the purchased grade or complete cosmetic.
• The framework in Regulation (EC) No 1223/2009 requires the completed product containing Dipotassium Glycyrrhizate to receive its own safety assessment before the finished product is marketed.
• Compare the received Dipotassium Glycyrrhizate material with its supplier specification and review destination-market filing needs.

5. Safety & risk assessment

Treat the listed amount as cosmetic-development guidance; it provides no evidence that a drug or OTC monograph applies and the completed formula still requires stability and patch testing.

6. Stability & packaging

Maintain cool, closed, light-protected storage for the bulk material; review airless or pump options if oxidation presents a concern; follow with stability and packaging checks on the confirmed batch.

7. Claims language (Do / Don’t)

• The cosmetic role of Dipotassium Glycyrrhizate is presented as licorice-salt comfort.

• This ingredient reference provides no basis for medical outcomes, cure language, or a product certification not supported by the available facts.
• The ingredient record for Dipotassium Glycyrrhizate does not confirm whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

Glycerin fills a polyol-humectant role in the listed cosmetic formats. Read its percentage as formulation guidance, not an assay.

3. Typical use levels (formulation guide)

• For gels and serums, the reference gives 3–8% as a formulation guide.
• For creams, the recorded level is 2–5% as a formulation guide.
• For rinse-off, use 2–4% as a formulation guide.

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

4. Regulatory sources & global compliance

• CosIng information about Glycerin does not itself authorize a particular grade or finished cosmetic.
• EU cosmetics rules under Regulation (EC) No 1223/2009 require a safety evaluation of the product containing Glycerin as it will be marketed as a finished-product assessment.
• Review the documentation for the actual Glycerin grade and the filing requirements for the target market.

5. Safety & risk assessment

The stated concentration is a cosmetic-development reference; it is not evidence of drug approval or OTC authorization and patch and stability testing remain part of finished-product review.

6. Stability & packaging

Keep bulk material sealed, cool, and out of direct sunlight; evaluate packaging against the formula's susceptibility to oxidation; confirm final stability and pack compatibility on a representative batch.

7. Claims language (Do / Don’t)

• The recorded cosmetic positioning for Glycerin highlights humectant function.

• The ingredient record provides no basis for a drug effect, a clinical cure, or certification status not established for the SKU.
• The Glycerin entry should not be cited in support of whitening, treatment of acne, perspiration control, sun protection, or hair growth.
