Pore Refining Toner Base

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

In cosmetic gels, emulsions, and washes, glycerin functions as a polyol humectant; its listed level is a guide.

3. Typical use levels (formulation guide)

• Gels and serums: 3–8% for the formula.
• For creams, the reference gives 2–5% for the formula.
• The guide range for rinse-off is 2–4%.

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

4. Regulatory sources & global compliance

• Treat any CosIng entry for Glycerin as a reference only; verify the grade and intended use under current market rules.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires a safety review of the finished cosmetic in which Glycerin is used before the finished product is marketed.
• Confirm the actual Glycerin grade from supplier documentation and check requirements where the product will be sold.

5. Safety & risk assessment

The guide records a level for cosmetic formulation purposes; it does not establish drug approval or OTC-monograph status and the completed formula still requires stability and patch testing.

6. Stability & packaging

Hold the bulk material in a sealed, cool place shielded from light; 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 cosmetic concept for Glycerin in this entry centers on humectant function.

• The ingredient record does not establish therapeutic results, cure claims, or unverified certification claims.
• The cosmetic guidance for Glycerin does not establish whitening effects, acne treatment, antiperspirant performance, sunscreen protection, or hair growth.

1. INCI & CAS

INCI: Propanediol · CAS: 504-63-2

2. Role in the formula

In cosmetic formulas, 1,3-propanediol is used as a humectant and solvent. It is not a substitute name for propylene glycol.

3. Typical use levels (formulation guide)

• For most water chassis, the reference gives 2–8%.

Incorporate Propanediol in the water phase.

4. Regulatory sources & global compliance

• A CosIng listing for Propanediol provides ingredient information, not approval of a supplied grade or finished product.
• Regulation (EC) No 1223/2009 requires a safety assessment of the finished cosmetic containing Propanediol before the cosmetic is placed on the EU market.
• Establish grade-specific details for Propanediol from the supplier and assess filing requirements in the intended market.

5. Safety & risk assessment

Use the stated level as reference guidance for cosmetic formulation; it does not qualify a finished product as a drug or OTC product and patch and stability testing remain part of finished-product review.

6. Stability & packaging

Protect the sealed bulk from heat, sun, and unnecessary exposure; where oxidation is a concern, evaluate airless or pump packaging; then verify formula stability and pack compatibility on the confirmed batch.

7. Claims language (Do / Don’t)

• This guide frames Propanediol's cosmetic direction around propanediol solvent.

• The cosmetic listing does not support therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• The ingredient note for Propanediol provides no basis for whitening, treatment of acne, perspiration control, sun protection, or hair growth.

1. INCI & CAS

INCI: Panthenol · CAS: 81-13-0

2. Role in the formula

D-panthenol's listed role is a water-soluble humectant in serums, gels, lotions, and washes. Use the level as formulation guidance only.

3. Typical use levels (formulation guide)

• For serums and gels, the recorded level is 1–5% in this reference.
• The stated reference for creams and lotions is 1–3% in this reference.
• The rinse-off washes use-level reference is 0.5–2% in this reference.

This water-soluble Panthenol is added in cool-down; the noted typical leave-on pH is about 5–6.

4. Regulatory sources & global compliance

• Database information on Panthenol does not replace review of the supplied grade and finished product under market rules.
• The framework in Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Panthenol at the level of the finished cosmetic product.
• Verify the purchased Panthenol grade using supplier data, alongside the applicable filing rules for the destination market.

5. Safety & risk assessment

The stated concentration is a cosmetic-development reference; it should not be read as a drug authorization or OTC listing with patch assessment and finished-formula stability testing still required.

6. Stability & packaging

Keep the bulk container closed and shaded in a cool area; evaluate packaging against the formula's susceptibility to oxidation; use batch testing to verify stability and package compatibility.

7. Claims language (Do / Don’t)

• This guide frames Panthenol's cosmetic direction around comfort and humectant support.

• The cosmetic listing cannot verify drug-treatment outcomes, clinical cures, or certifications not documented for the SKU.
• The cosmetic guidance for Panthenol provides no basis for whitening, acne treatment, antiperspirant effects, sunscreen use, or hair growth.
