Foot Soak Concentrate Base

1. INCI & CAS

INCI: Urea · CAS: 57-13-6

2. Role in the formula

Urea is listed as a humectant in this development reference. The recorded formula also lists Sodium Lactate and Lactic Acid. Review moisture feel and tack in the complete formula.

3. Typical use levels (formulation guide)

• In this reference, the component allocation is 12% w/w.

Dissolve in water. Urea can drift pH; set the finished pH after addition.

4. Regulatory sources & global compliance

• This entry is a formulation-development reference; it does not verify or approve the material grade or completed formula; The note should not be read as approval of the final formula.

5. Safety & risk assessment

This formulation note gives a cosmetic-use reference level; no drug approval or OTC status is conferred by this entry with patch response and finished-product stability still to be verified.

6. Stability & packaging

Keep the bulk container closed and shaded in a cool area; for oxidation-sensitive formulas, consider an airless or pump pack; confirm compatibility and stability using the selected formula and pack.

7. Claims language (Do / Don’t)

• The cosmetic formulation concept for Urea centers on urea softening.

• The development record cannot substantiate drug-treatment outcomes, clinical cures, or certifications not documented for the SKU.
• The documented facts for Urea is not evidence for whitening, acne-treatment, antiperspirant, sun-protection, or hair-growth benefits.

1. INCI & CAS

INCI: Sodium Lactate · CAS: 72-17-3

2. Role in the formula

Sodium Lactate is listed as a humectant in this development reference. The recorded formula also lists Urea and Lactic Acid. Review moisture feel and tack in the complete formula.

3. Typical use levels (formulation guide)

• The formulation record gives 10% w/w as the component allocation.

Use the water phase to introduce Sodium Lactate.

4. Regulatory sources & global compliance

• This listing is guidance for formula development; it does not authorize a particular grade or finished formula; The reference does not authorize a finished product.

5. Safety & risk assessment

The stated concentration is a cosmetic-development reference; the listed level does not itself confer drug or OTC status and the completed cosmetic needs its own patch and stability checks.

6. Stability & packaging

Protect the sealed bulk from heat, sun, and unnecessary exposure; if oxidation risk calls for it, review a pump or airless format; verify the chosen pack against the tested formula.

7. Claims language (Do / Don’t)

Lactic Acid is listed as an acid component in this development reference. The recorded formula also lists Urea and Sodium Lactate. Review its intended role and the measured pH of this complete formula.

3. Typical use levels (formulation guide)

• This entry shows a reference allocation of 0.5% w/w.

Add after the main phases and check pH. Label destination AHA precautions when the level requires them.

4. Regulatory sources & global compliance

• The record provides guidance for development; it does not approve the supplied grade or finished product; The note should not be read as approval of the final formula.

5. Safety & risk assessment

Use the stated level as reference guidance for cosmetic formulation; the note establishes neither drug approval nor OTC-monograph status so the finished cosmetic should receive patch and stability checks.

6. Stability & packaging

Keep bulk material sealed, cool, and out of direct sunlight; evaluate packaging against the formula's susceptibility to oxidation; test the selected package with the confirmed batch for stability and fit.
