Tranexamic Acid Serum Base

1. INCI & CAS

INCI: Tranexamic Acid · CAS: 1197-18-8

2. Role in the formula

Cosmetic guides often explore about 2–3% tranexamic acid in leave-on serums. This page does not claim a medicine, a injection use, or a guaranteed spot result.

3. Typical use levels (formulation guide)

• Serums may use the guide range 2–3% where the market allows as a formulation guide.

For dissolution, use water. Confirm the destination cosmetic listing before filing.

4. Regulatory sources & global compliance

• Use CosIng's information on Tranexamic Acid as a reference, then verify the specific grade and intended use under market rules.
• Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Tranexamic Acid at the level of the finished cosmetic product.
• Confirm the received Tranexamic Acid grade against supplier documentation, then verify the intended market's filing requirements.

5. Safety & risk assessment

The percentage is shown for cosmetic development; it does not authorize 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 appropriate, assess an airless or pump pack for oxidation-sensitive systems; use batch testing to verify stability and package compatibility.

7. Claims language (Do / Don’t)

• The cosmetic concept for Tranexamic Acid in this entry centers on tranexamic-acid cosmetic.

• The formulation note cannot substantiate claims of drug activity, a clinical cure, or an undocumented product certification.
• This reference for Tranexamic Acid does not demonstrate whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI & CAS

INCI: Glycerin · CAS: 56-81-5

2. Role in the formula

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

3. Typical use levels (formulation guide)

• The stated reference for gels and serums is 3–8% as a formulation guide.
• Creams: 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

• CosIng information about Glycerin does not itself authorize a particular grade or finished cosmetic.
• The EU Cosmetics Regulation (EC) No 1223/2009 requires an assessment of the safety of the final cosmetic containing Glycerin in the final product context.
• Review the supplier TDS for the received Glycerin grade, together with the target market's current filing requirements.

5. Safety & risk assessment

The listed use rate is intended as a cosmetic-development guide; it makes no claim of drug or OTC authorization 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; if oxidation risk calls for it, review a pump or airless format; check the finished batch's stability and package compatibility.

7. Claims language (Do / Don’t)

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

• The ingredient record does not demonstrate therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• This guide to Glycerin does not establish a skin-lightening result, acne treatment, antiperspirant action, sunscreen efficacy, or hair growth.

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)

• The formulation record indicates 2–8% for most water chassis for the formula.

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.
• EU market placement under Regulation (EC) No 1223/2009 requires a safety assessment of the complete cosmetic formula containing Propanediol in the final product context.
• For Propanediol, check the purchased grade against its supplier TDS and review filing requirements in the destination market.

5. Safety & risk assessment

The stated concentration is a cosmetic-development reference; it is not evidence of drug approval or OTC authorization and the completed formula still requires stability and patch testing.

6. Stability & packaging

Protect the sealed bulk from heat, sun, and unnecessary exposure; where oxidation is a concern, evaluate airless or pump packaging; use batch testing to verify stability and package compatibility.

7. Claims language (Do / Don’t)

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

• This product entry cannot verify therapeutic outcomes, clinical cures, or a certification the finished SKU does not hold.
• The ingredient note for Propanediol does not demonstrate a whitening result, acne-treatment effect, antiperspirant use, sunscreen performance, or hair growth.
