Hydrating Water Gel Base

1. INCI e CAS

INCI: Glycerin · CAS: 56-81-5

2. Ruolo nella formula

Glycerin fills a polyol-humectant role in the listed cosmetic formats. Read its percentage as formulation guidance, not an assay.

3. Livelli d'uso tipici (guida di formulazione)

• The level shown for gels and serums is 3–8% for the formula.
• For creams, the reference gives 2–5%.
• The guide range for rinse-off is 2–4% in this reference.

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

4. Fonti normative e conformità globale

• The CosIng record for Glycerin, where listed, is informational rather than product-specific authorization.
• EU market placement under Regulation (EC) No 1223/2009 requires a safety assessment of the finished cosmetic containing Glycerin for the specific product as it will be marketed.
• Match the selected Glycerin material to its supplier TDS and check the filing list for the market of sale.

5. Sicurezza e valutazione del rischio

The percentage is shown for cosmetic development; this reference is not approval for drug use or OTC marketing with patch and stability testing still needed for the completed formula.

6. Stabilità e packaging

Hold the bulk material in a sealed, cool place shielded from light; select packaging with the formula's oxidation sensitivity in mind; use batch testing to verify stability and package compatibility.

7. Linguaggio dei claim (cosa dire / cosa non dire)

• The formulation note describes Glycerin as part of a cosmetic direction focused on humectant function.

• This ingredient reference provides no basis for drug claims, cure claims, or a certification that is absent from the product records.
• This cosmetic entry naming Glycerin should not be used to substantiate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI e CAS

INCI: Propanediol · CAS: 504-63-2

2. Ruolo nella formula

1,3-propanediol serves as a cosmetic humectant and solvent in this guidance, distinct from propylene glycol.

3. Livelli d'uso tipici (guida di formulazione)

• The level shown for most water chassis is 2–8% for the formula.

Route Propanediol through the water phase.

4. Fonti normative e conformità globale

• 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 a safety assessment of the finished cosmetic containing Propanediol for the complete formula intended for sale.
• Confirm the actual Propanediol grade from supplier documentation and check requirements where the product will be sold.

5. Sicurezza e valutazione del rischio

The listed use rate is intended as a cosmetic-development guide; it does not establish drug approval or OTC-monograph status while finished-product patch and stability testing remain necessary.

6. Stabilità e packaging

Protect the sealed bulk from heat, sun, and unnecessary exposure; if the formula is oxidation-sensitive, an airless or pump format may be considered; verify the chosen pack against the tested formula.

7. Linguaggio dei claim (cosa dire / cosa non dire)

• The cosmetic formulation concept for Propanediol centers on propanediol solvent.

• The listed information provides no basis for drug claims, cure claims, or a certification that is absent from the product records.
• The information about Propanediol cannot verify whitening, acne treatment, antiperspirant action, sunscreen use, or hair-growth outcomes.

1. INCI e CAS

INCI: Hydroxyethylcellulose · CAS: 9004-62-0

2. Ruolo nella formula

HEC builds clear gels without a carbomer neutralization story.

3. Livelli d'uso tipici (guida di formulazione)

• Gels: 0.3–0.8% for the formula.

Disperse in glycerin or water and hydrate fully.

4. Fonti normative e conformità globale

• CosIng may identify Hydroxyethylcellulose as an ingredient, but its entry does not approve a material grade or finished formula.
• EU cosmetics rules under Regulation (EC) No 1223/2009 require the finished product's safety, including the formula in which Hydroxyethylcellulose is used, to be assessed as a finished-product assessment.
• Confirm the received Hydroxyethylcellulose grade against supplier documentation, then verify the intended market's filing requirements.

5. Sicurezza e valutazione del rischio

This formulation note gives a cosmetic-use reference level; it should not be read as a drug authorization or OTC listing so the finished cosmetic should receive patch and stability checks.

6. Stabilità e packaging

Store the bulk in a closed container in a cool, shaded place; where appropriate, assess an airless or pump pack for oxidation-sensitive systems; check the finished formula and its packaging together.

7. Linguaggio dei claim (cosa dire / cosa non dire)

• This guide frames Hydroxyethylcellulose's cosmetic direction around clear-gel thickener.

• The formulation note does not support drug effects, clinical cures, or unsupported product certifications.
• The documented facts for Hydroxyethylcellulose does not establish whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.
