Nanoparticles Development for Cosmetics and Personal Care Applications

Nanoparticles have found a variety of applications in the cosmetics and personal care industry due to their unique properties, which can enhance product performance, stability, and user experience. The major applications of nanoparticles include:

• Sunscreens
  • Zinc Oxide and Titanium Dioxide: These nanoparticles are commonly used as physical UV filters in sunscreens. Their nano-sized form is more effective for scattering and reflecting UV radiation, providing broad-spectrum protection without leaving a visible white residue typically associated with larger particle sizes.
• Anti-Aging Products
  • Gold and Silver Nanoparticles: Incorporated into creams and serums, these nanoparticles are believed to have antioxidant properties and can promote collagen synthesis, potentially reducing the appearance of wrinkles and fine lines.
  • Nanolipid Carriers: Used for the delivery of vitamins and peptides, these carriers can enhance the penetration of active ingredients, improving their efficacy in anti-aging formulations.
• Makeup Products
  • Light-Reflecting Nanoparticles: Silica and other nanoparticles can create a blurring effect, enhancing the appearance of skin by diffusing light and improving the texture of products like foundations and powders.
  • Color Cosmetics: The use of nanoparticles can improve the stability and delivery of pigments in lipsticks, eye shadows, and other color cosmetics, providing better color payoff and longer-lasting wear.
• Hair Care
  • Nanoparticle-Enhanced Conditioners: Nanoparticles can be used to penetrate the hair shaft, providing moisture, healing properties, and protection from damage. For example, nanoscale keratin can help strengthen hair.
  • Scalp Treatments: Nanoparticle formulations can deliver active ingredients to the scalp more effectively, promoting hair growth and addressing concerns like dandruff.

What We Can Do for You

The development procedures for incorporating nanoparticles into the cosmetics and personal care products involve several stages.

STEMart provides one-stop nanoparticle development service including:

• Determine the specific food application for nanoparticles, such as UV protection, antimicrobial effects, and improved texture.
• Define desired properties such as size, shape, surface charge, and stability.
• Choose appropriate materials for nanoparticle synthesis. Common nanoparticles used in cosmetics include titanium dioxide (TiO2), zinc oxide (ZnO), silica, and liposomes.
• Matrix Selection: Choosing appropriate bases (e.g., creams, lotions, gels) that can effectively incorporate and stabilize nanoparticles.
  • Compatibility Testing: Ensuring that the nanoparticles do not react negatively with other formulation components, such as preservatives, active ingredients, or emulsifiers.
• Determining the optimal concentration of nanoparticles to achieve desired effects without compromising safety or efficacy.
• Select suitable synthesis method depending on the desired properties.
• Characterize properties of nanoparticles, such as stability, compatibility with other ingredients, biocompatibility with skin or mucous membranes, potential cytotoxicity and genotoxicity, etc.
