Hydrating Facial Toner Base

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

The reference uses glycerin as a polyol humectant across washes, gels, and emulsions. Treat the percentage as development guidance.

3. Typical use levels (formulation guide)

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

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

4. Regulatory sources & global compliance

• An entry for Glycerin in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• EU market placement under Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Glycerin for the completed formula, not simply for an ingredient in isolation.
• Confirm the actual Glycerin grade from supplier documentation and check requirements where the product will be sold.

5. Safety & risk assessment

Use the stated level as reference guidance for cosmetic formulation; it makes no claim of drug or OTC authorization and the completed cosmetic needs its own patch and stability checks.

6. Stability & packaging

Store the bulk in a closed container in a cool, shaded place; for oxidation-sensitive formulas, consider an airless or pump pack; confirm stability and pack fit with the final formula.

7. Claims language (Do / Don’t)

• The listed cosmetic direction for Glycerin emphasizes humectant function.

• The development record cannot substantiate therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• The documented facts for Glycerin does not substantiate whitening, acne treatment, antiperspirant effects, sunscreen use, or hair growth.

1. INCI & CAS

INCI: Propanediol · CAS: 504-63-2

2. Role in the formula

This cosmetic-formulation note assigns 1,3-propanediol humectant and solvent functions; the ingredient is not propylene glycol.

3. Typical use levels (formulation guide)

• The formulation record indicates 2–8% for most water chassis as a formulation guide.

Route Propanediol through the water phase.

4. Regulatory sources & global compliance

• CosIng provides reference information for Propanediol; confirm the specific grade and intended use against market requirements.
• The finished-product provisions of Regulation (EC) No 1223/2009 require a safety assessment of the complete cosmetic formula containing Propanediol at the level of the finished cosmetic product.
• Match the selected Propanediol material to its supplier TDS and check the filing list for the market of sale.

5. Safety & risk assessment

The percentage is shown for cosmetic development; it is not evidence of drug approval or OTC authorization 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; consider an airless or pump format when oxidation sensitivity warrants it; check the finished formula and its packaging together.

7. Claims language (Do / Don’t)

• For cosmetic use, this entry records Propanediol in a direction centered on propanediol solvent.

• This ingredient reference cannot substantiate therapeutic results, cure claims, or unverified certification claims.
• The cosmetic guidance for Propanediol should not be used to substantiate skin whitening, treatment of acne, sweat control, UV protection, or hair-growth results.

1. INCI & CAS

INCI: Panthenol · CAS: 81-13-0

2. Role in the formula

For serums, gels, lotions, and washes, D-panthenol is presented as a water-soluble humectant. The stated amount is not an assay.

3. Typical use levels (formulation guide)

• Formulation guidance for serums and gels: 1–5%.
• For creams and lotions, use 1–3% as a formulation guide.
• For rinse-off washes, the reference gives 0.5–2% for the formula.

Use cool-down addition for Panthenol; it is water-soluble, with a typical leave-on pH of about 5–6.

4. Regulatory sources & global compliance

• Use CosIng's information on Panthenol as a reference, then verify the specific grade and intended use under market rules.
• Before EU placement, Regulation (EC) No 1223/2009 requires a product-level safety assessment for the complete formula that contains Panthenol for the product in its final form.
• Verify the purchased Panthenol grade using supplier data, alongside the applicable filing rules for the destination market.

5. Safety & risk assessment

This level is a cosmetic-formulation guide; it does not qualify a finished product as a drug or OTC product 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; review airless or pump options if oxidation presents a concern; verify the chosen pack against the tested formula.

7. Claims language (Do / Don’t)

• The cosmetic concept for Panthenol in this entry centers on comfort and humectant support.

• This ingredient reference does not demonstrate therapeutic results, cure claims, or unverified certification claims.
• The available details for Panthenol offers no support for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
