Tone Refining Gel Cream Base

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)

• Gels and serums may use the guide range 3–8%.
• The formulation record indicates 2–5% for creams.
• The level shown for rinse-off is 2–4%.

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

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 assessment covering the complete formulation with Glycerin for the specific product as it will be marketed.
• Establish grade-specific details for Glycerin from the supplier and assess filing requirements in the intended market.

5. Safety & risk assessment

The listed use rate is intended as a cosmetic-development guide; this reference is not approval for drug use or OTC marketing so patch response and stability should be checked on the finished product.

6. Stability & packaging

For bulk storage, avoid warmth and direct sun and keep the container closed; 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.

• This product entry cannot substantiate therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• The Glycerin entry provides no basis for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI & CAS

INCI: Propanediol · CAS: 504-63-2

2. Role in the formula

The reference uses 1,3-propanediol for humectant and solvent roles in cosmetic formulas; it does not mean propylene glycol.

3. Typical use levels (formulation guide)

• The stated reference for most water chassis is 2–8%.

Route Propanediol through the water phase.

4. Regulatory sources & global compliance

• CosIng may identify Propanediol as an ingredient, but its entry does not approve a material grade or finished formula.
• Regulation (EC) No 1223/2009 sets the requirement for the complete cosmetic containing Propanediol to receive its own safety assessment before release of the finished cosmetic.
• Confirm the actual Propanediol 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 is not evidence of drug approval or OTC authorization and the completed formula still requires stability and patch testing.

6. Stability & packaging

Keep the ingredient in cool, closed bulk storage away from sunlight; if oxidation risk calls for it, review a pump or airless format; test the selected package with the confirmed batch for stability and fit.

7. Claims language (Do / Don’t)

• The formulation note describes Propanediol as part of a cosmetic direction focused on propanediol solvent.

• The available ingredient details does not establish claims of drug action or cure, or a product certification outside the supporting records.
• This guide to Propanediol does not demonstrate skin whitening, acne care, sweat reduction, sun protection, or hair-growth outcomes.

1. INCI & CAS

INCI: Hydroxyethylcellulose · CAS: 9004-62-0

2. Role in the formula

HEC builds clear gels without a carbomer neutralization story.

3. Typical use levels (formulation guide)

• For gels, use 0.3–0.8% for the formula.

Disperse in glycerin or water and hydrate fully.

4. Regulatory sources & global compliance

• CosIng provides reference information for Hydroxyethylcellulose; confirm the specific grade and intended use against market requirements.
• Regulation (EC) No 1223/2009 requires a safety assessment covering the complete formulation with Hydroxyethylcellulose for the complete formula intended for sale.
• Establish grade-specific details for Hydroxyethylcellulose from the supplier and assess filing requirements in the intended market.

5. Safety & risk assessment

The guide records a level for cosmetic formulation purposes; it should not be read as a drug authorization or OTC listing so assess patch response and stability in the final formula.

6. Stability & packaging

Store sealed bulk away from heat and sunlight; where oxidation is a concern, evaluate airless or pump packaging; follow with stability and packaging checks on the confirmed batch.

7. Claims language (Do / Don’t)

• The recorded cosmetic positioning for Hydroxyethylcellulose highlights clear-gel thickener.

• This formulation entry does not establish claims of drug action or cure, or a product certification outside the supporting records.
• The available details for Hydroxyethylcellulose should not be used to substantiate skin whitening, acne treatment, antiperspirant use, sun protection, or hair growth.
