Dark Spot Care Gel 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)

• The stated reference for serums is 1–2% as a formulation guide.
• Formulation guidance for creams: 0.5–2% in this reference.

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

4. Regulatory sources & global compliance

• Treat any CosIng entry for Alpha-Arbutin as a reference only; verify the grade and intended use under current market rules.
• An EU-market cosmetic 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.
• Check the supplier's technical information for the Alpha-Arbutin grade and confirm the relevant market filing list.

5. Safety & risk assessment

The guide records a level for cosmetic formulation purposes; the note establishes neither drug approval nor OTC-monograph status while finished-product patch and stability testing remain necessary.

6. Stability & packaging

Keep bulk material sealed, cool, and out of direct sunlight; match the pack choice to the system's oxidation risk; verify the chosen pack against the tested formula.

7. Claims language (Do / Don’t)

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

• The listed information does not support drug-treatment outcomes, clinical cures, or certifications not documented for the SKU.
• The ingredient note for Alpha-Arbutin should not be used to substantiate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

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 level shown for serums and creams is 0.1–0.5%.

Dissolve in the water phase.

4. Regulatory sources & global compliance

• An entry for Dipotassium Glycyrrhizate in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• An EU-market cosmetic under Regulation (EC) No 1223/2009 requires the finished product's safety, including the formula in which Dipotassium Glycyrrhizate is used, to be assessed as a finished-product assessment.
• Compare the received Dipotassium Glycyrrhizate material with its supplier specification and review destination-market filing needs.

5. Safety & risk assessment

The listed use rate is intended as a cosmetic-development guide; it does not establish drug approval or OTC-monograph status while finished-product patch and stability testing remain necessary.

6. Stability & packaging

Keep bulk supplies closed, cool, and protected from sunlight; where appropriate, assess an airless or pump pack for oxidation-sensitive systems; use batch testing to verify stability and package compatibility.

7. Claims language (Do / Don’t)

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

• The ingredient record provides no basis for a drug effect, a clinical cure, or certification status not established for the SKU.
• The available details for Dipotassium Glycyrrhizate does not establish whitening, acne treatment, antiperspirant effects, sunscreen use, or hair growth.

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

This entry describes glycerin as a polyol humectant for gels, emulsions, and washes, with a guide level rather than a batch result.

3. Typical use levels (formulation guide)

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

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

4. Regulatory sources & global compliance

• CosIng information about Glycerin does not itself authorize a particular grade or finished cosmetic.
• Regulation (EC) No 1223/2009 sets the requirement for an assessment of the safety of the final cosmetic containing Glycerin for the specific product as it will be marketed.
• Review the documentation for the actual Glycerin grade and the filing requirements for the target market.

5. Safety & risk assessment

This formulation note gives a cosmetic-use reference level; the listed level does not itself confer drug or OTC status with patch and stability testing still needed for the completed formula.

6. Stability & packaging

Store the bulk in a closed container in a cool, shaded place; 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 formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.

• The development record does not demonstrate claims of drug activity, a clinical cure, or an undocumented product certification.
• The information about Glycerin should not be cited in support of whitening, treatment of acne, perspiration control, sun protection, or hair growth.
