Understanding Long-Lash™ and the Water Phase for Eyelash Serum

Based on your question and the information about Long-Lash™, here's a breakdown:

What is Long-Lash™?

Long-Lash™ is an ingredient designed to help eyelashes grow longer and denser. It contains Growth Complex Peptides, specifically Myristoyl Pentapeptide-17 and Copper Tripeptide-1. These peptides work by stimulating the genes responsible for creating keratin, a key protein in hair (including eyelashes).

According to the product information, you can start seeing results in as little as 2 weeks, with more noticeable results after 6 weeks of consistent use.

What is the "Water Phase"?

As discussed in the forum replies, the "water phase" in cosmetic formulation refers to the part of your mixture that consists of water and any ingredients that dissolve in water. It is not typically just plain tap water.

Using purified water (like distilled or deionized water) is crucial for cosmetic formulations to ensure stability, prevent microbial growth, and avoid interference from minerals found in tap water. The water phase might also include other water-soluble ingredients needed for the specific serum formula, such as thickeners, humectants, or preservatives.

How to Mix Long-Lash™ with the Water Phase?

The product description for Long-Lash™ states that it should be mixed into the water phase. Key instructions are:

• Mixing Method: Mix directly into the water phase.
• Avoid Heat: Do not expose Long-Lash™ to heat during the mixing process.
• Usage Rate: Use Long-Lash™ at a concentration of 5-10% in your final formula. Do not exceed 10%, as this can cause irritation.

Important Formulation Notes for Long-Lash™:

• Application: Apply the finished serum to the base of the eyelashes, not just the lashes themselves, for best results.
• Compatibility: It is critical to avoid using ingredients that can interfere with the peptides, especially the Copper Tripeptide-1. Do not include Disodium EDTA or any type of Chelating Agent (such as AHAs like Lactic Acid, Glycolic Acid, or Citric Acid) in your formula, as they will reduce the effectiveness of Long-Lash™.
• Complementary Ingredients: Long-Lash™ can be used together with Pep®-Brow (Acetyl Tetrapeptide-3) to potentially increase efficiency.

Creating a stable and effective cosmetic product requires a complete, tested formulation that specifies all ingredients, their amounts, and the correct mixing procedure. Simply mixing Long-Lash™ with plain water is not recommended and may not yield the desired results or could potentially cause issues, as highlighted by the staff member in the forum.

For successful results, it is best to follow a professionally developed formula or consult with a formulator.
