Revised Cracked Heel Cream Formulation

Subject: Cracked Heel Cream Formulation Review

Regarding your cracked heel cream formulation and questions:

The staff has reviewed your formula and proposed a revised version to better suit the needs of cracked heels and achieve a thicker, butter-like texture.

Here's a summary of the staff's recommendations and why:

• Revised Formula: The staff suggested a formula including:

  • Papaya Enzyme (2.0%) - Increased slightly as heel skin is thicker.
  • Shea Butter (10%) - Reduced to avoid stickiness.
  • Sweet Almond Oil (4%)
  • Disodium EDTA (0.2%)
  • Butter Cream Maker (4%)
  • Phenoxyethanol SA (1%)
  • Sodium Lactate (7%) - Added for exfoliation and moisture, beneficial for cracked heels.
  • Cetearyl Alcohol (5%) - Added to help thicken the cream to a butter-like consistency.
  • Water (remaining percentage)

• Suitability and Texture: The revised formula is considered more suitable for cracked heels due to the adjusted Papaya Enzyme level and the addition of Sodium Lactate. The addition of Cetearyl Alcohol is specifically recommended to ensure the cream achieves a thicker, butter-like texture, as omitting it might result in a more lotion-like consistency.

• Omitting Disodium EDTA: The staff included Disodium EDTA in their recommended formula. While not explicitly stated why it cannot be omitted, Disodium EDTA acts as a chelating agent, helping to improve formula stability and prevent issues caused by metal ions. Therefore, it is generally recommended for formula longevity and stability.

The staff also provided a detailed mixing procedure for the revised formula.
