Myristoyl Pentapeptide-17 powder is a synthetic peptide raw material prepared through peptide synthesis, purification, and drying steps. It appears as a white powder and dissolves in water, which makes it easier to handle during raw material evaluation, sampling, and early formula work. It is not a plant extract or a blended amino acid material, but a lab-made peptide developed for cosmetic use.
This material is mainly used in lash and brow care products, especially clear serums, light essence systems, and other water-based formats. In this type of product, it is usually added as a conditioning ingredient to give the formula a more focused care direction. Compared with general cosmetic actives, it is more often placed in eyelash serum and eyebrow serum development.
Shaanxi Medibridge Biotech Co., Ltd. focuses on peptide raw materials and cosmetic ingredient supply. We pay attention to batch consistency, document support, and clear communication during purchasing and sample follow-up. Packaging options and supply details can be discussed according to actual project requirements, making the material easier to match with routine sourcing and formula development work.

How It Works

How It Fits into a Formula
A Functional Peptide Ingredient
In most cases, this material is added as a functional part of the formula, not as a bulk base ingredient. It is usually selected when the product is designed specifically for lash or brow care.
Suitable for Light Systems
Because it dissolves in water, it is easier to use in clear serums, eyebrow serums, eyelash care products, and other lightweight systems. This makes it a practical option for formulas that need a clean and simple texture.
Easy to Combine with Other Materials
During formulation, it can be used together with humectants, conditioning ingredients, and other support materials. This kind of combination is common in products developed for daily lash and brow care.

Typical Application Areas
Eyelash Serums
This material is often used in eyelash serum products, especially in leave-on systems with a light texture and a clear care purpose.
Eyebrow Serums
It is also suitable for eyebrow care formulas. Since brow serums often follow a similar product structure, this peptide can fit naturally into that type of system.
Lash and Brow Conditioning Products
Besides standard serums, it can also be used in other conditioning products made for daily lash and brow care.
Water-Based Cosmetic Systems
Its water solubility makes it easier to work with in lightweight and water-based products, including clear serums and similar care formats.

Storage & Handling
Keep Sealed and Dry
Store in a sealed container and keep it in a dry place to reduce moisture exposure.
Store at Room Temperature
This material is generally stored at room temperature under normal dry conditions.
Handle with Routine Care
During use, it should be handled according to normal cosmetic raw material practice to keep the material clean and stable.
