Alpha Arbutin 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)

• 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. 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 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

Cosmetic washes, gels, and emulsions use glycerin in a polyol-humectant role; the listed level is for formulation development.

3. Typical use levels (formulation guide)

• 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. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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 & CAS

INCI: Propanediol · CAS: 504-63-2

2. Role in the formula

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

3. Typical use levels (formulation guide)

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

The water phase is the addition point for Propanediol.

4. Regulatory sources & global compliance

• 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. Safety & risk assessment

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. Stability & packaging

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. Claims language (Do / Don’t)

• 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.
