repair and strengthening toner

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)

• For gels and serums, use 3–8% as a formulation guide.
• The formulation record indicates 2–5% for creams for the formula.
• The formulation record indicates 2–4% for rinse-off.

The guide places Glycerin in the water phase and calls for no melt step.

4. Regulatory sources & global compliance

• CosIng may identify Glycerin as an ingredient, but its entry does not approve a material grade or finished formula.
• For an EU-market product, Regulation (EC) No 1223/2009 requires the finished product's safety, including the formula in which Glycerin is used, to be assessed for the specific product as it will be 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; no drug approval or OTC status is conferred by this entry and the final formula should undergo patch and stability assessment.

6. Stability & packaging

Keep bulk supplies closed, cool, and protected from sunlight; consider an airless or pump format when oxidation sensitivity warrants it; check the finished batch's stability and package compatibility.

7. Claims language (Do / Don’t)

• For cosmetic use, this entry records Glycerin in a direction centered on humectant function.

• The available ingredient details cannot verify drug effects, clinical cures, or unsupported product certifications.
• The available details for Glycerin cannot verify skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.

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)

• For most water chassis, use 2–8% in this reference.

Add Propanediol to the water phase.

4. Regulatory sources & global compliance

• An entry for Propanediol in CosIng is not authorization for a material grade or completed cosmetic; review local requirements.
• For an EU-market product, Regulation (EC) No 1223/2009 requires the completed product containing Propanediol to receive its own safety assessment as a finished-product assessment.
• Review the documentation for the actual Propanediol grade and the filing requirements for the target market.

5. Safety & risk assessment

This entry provides guidance for cosmetic use only; it does not establish drug approval or OTC-monograph status and the completed formula still requires stability and patch testing.

6. Stability & packaging

Keep the bulk container closed and shaded in a cool area; review airless or pump options if oxidation presents a concern; then verify formula stability and pack compatibility on the confirmed batch.

7. Claims language (Do / Don’t)

• The cosmetic role of Propanediol is presented as propanediol solvent.

• This reference does not demonstrate therapeutic results, cure claims, or unverified certification claims.
• The ingredient record for Propanediol does not establish whitening, acne care as treatment, perspiration reduction, sun protection, or hair growth.

1. INCI & CAS

INCI: Panthenol · CAS: 81-13-0

2. Role in the formula

This guide places water-soluble D-panthenol in serum, gel, lotion, and wash formulations; its level is a reference, not a measured batch value.

3. Typical use levels (formulation guide)

• Serums and gels may use the guide range 1–5%.
• 1–3% is listed for creams and lotions for the formula.
• For rinse-off washes, the recorded level is 0.5–2% in this reference.

Add Panthenol after the main heat phase during cool-down; the ingredient is water-soluble and leave-on pH is typically about 5–6.

4. Regulatory sources & global compliance

• CosIng may identify Panthenol as an ingredient, but its entry does not approve a material grade or finished formula.
• For cosmetics placed on the EU market, Regulation (EC) No 1223/2009 requires the completed product containing Panthenol to receive its own safety assessment rather than for an ingredient name alone.
• Use the supplier TDS to confirm grade-specific details for Panthenol and review the destination market's requirements.

5. Safety & risk assessment

Treat the listed amount as cosmetic-development guidance; the note establishes neither drug approval nor OTC-monograph status with patch and stability testing still needed for the completed formula.

6. Stability & packaging

Use cool, sealed storage away from strong light for the bulk; select packaging with the formula's oxidation sensitivity in mind; use batch testing to verify stability and package compatibility.

7. Claims language (Do / Don’t)

• The cosmetic role of Panthenol is presented as comfort and humectant support.

• This reference does not establish claims of drug activity, a clinical cure, or an undocumented product certification.
• The cosmetic guidance for Panthenol does not substantiate a whitening effect, acne treatment, perspiration control, sun protection, or hair growth.
