Sunscreen efficacy is paramount in protecting the skin from harmful UV radiation. However, a common challenge for formulators is ensuring that this protection remains effective, especially when exposed to water or sweat. This is where specialized ingredients like 1,2-Pentanediol (CAS 5343-92-0) come into play. As a trusted supplier of high-quality cosmetic raw materials, we highlight the significant role 1,2-Pentanediol plays in enhancing the water resistance of sunscreen formulations. If you're looking to buy 1,2-Pentanediol to improve your sunscreen performance, this information is crucial.

The Challenge of Water Resistance in Sunscreens
Sunscreen formulations are designed to adhere to the skin and provide a protective barrier. However, water and sweat can disrupt this film, leading to a reduction in SPF and critical UV protection. Regulatory bodies often require sunscreens to undergo water resistance testing (e.g., 40 or 80 minutes of water immersion), making ingredients that improve this property highly valuable.

1,2-Pentanediol's Contribution to Water Resistance

  • Film-Forming Properties: 1,2-Pentanediol acts as a humectant and emollient, contributing to a smoother, more continuous film on the skin's surface. This improved film integrity helps to better anchor the UV filters, making them less susceptible to wash-off.
  • Solvency and Compatibility: Its excellent solvency allows 1,2-Pentanediol to effectively dissolve and homogenize various components within a sunscreen formulation, including UV filters and other functional ingredients. This uniform distribution contributes to a more stable and robust protective film.
  • Synergistic Effects: When used in conjunction with other film-forming agents or adhesion promoters, 1,2-Pentanediol can exhibit synergistic effects, further enhancing the overall water resistance of the sunscreen.
  • Enhanced Feel: Beyond its functional benefits, 1,2-Pentanediol also contributes to a pleasant skin feel, reducing the tackiness often associated with high concentrations of UV filters, making the sunscreen more comfortable for daily wear.
  • Dual Functionality: As a humectant, it also helps to combat the drying effects of some UV filters and environmental exposure, ensuring the skin remains hydrated while protected.
