Sunscreen plays a crucial role in skincare, shielding the skin from harmful UV rays that lead to sunburn, premature aging, and skin cancer.
With rising consumer awareness, the sunscreen market has grown rapidly, as more people recognize the importance of daily sun protection to maintain healthy skin.
Formulating high SPF sunscreens can be challenging.
It requires achieving effective UV protection while ensuring the product feels good on the skin, spreads evenly, and maintains its stability throughout its shelf life, which is essential for both consumer satisfaction and product performance.
Types of UV Radiation and Their Impact
UVA, UVB, UVC
Ultraviolet (UV) radiation comes in three types: UVA, UVB, and UVC.
UVA rays penetrate deep into the skin, leading to signs of aging like wrinkles and fine lines.
UVB rays affect the skin’s outer layer, causing sunburn and increasing the risk of skin cancer.
UVC rays, fortunately, are absorbed by the atmosphere and do not reach the Earth’s surface.
Need for Broad-Spectrum Protection
To protect against the harmful effects of UV radiation, broad-spectrum sunscreens are essential.
These sunscreens provide defense against both UVA and UVB rays. While UVA rays contribute to premature aging,
UVB rays are the main culprits behind painful sunburns and skin damage.
Using broad-spectrum protection ensures healthier, youthful-looking skin while reducing the risk of long-term damage.
Key Principles of Sunscreen Formulation
#1 Homogeneous Distribution of UV Filters for Maximum Efficacy
For sunscreens to work effectively, the UV filters must be evenly distributed on the skin.
When the filters are applied uniformly, they provide complete protection from harmful rays.
Uneven distribution can create weak spots, leaving parts of the skin vulnerable to sunburn and other damage, significantly reducing the product’s protective power.
#2 Importance of Spreadability and Even Coverage
Smooth application is essential for effective sun protection.
At Zicail, we prioritize creating sunscreens that spread easily and provide even coverage, ensuring the skin is fully protected.
A sunscreen that applies smoothly helps users cover their skin more thoroughly, making it easier to apply the right amount and reduce the risk of missed spots.
#3 Factors Affecting Sunscreen Performance
Stability, solubility, and avoiding crystallization are crucial factors for maintaining a sunscreen’s effectiveness over time.
Zicail focuses on these elements to ensure that our sunscreens perform consistently throughout their shelf life.
By maintaining a stable formulation, we prevent issues like crystallization, which can negatively impact the texture and protective qualities of the sunscreen.
Selection of UV Filters
Chemical vs. Mineral UV Filters: Differences and Mechanisms
When it comes to UV filters, there are two main types: chemical and mineral.
Chemical filters, such as avobenzone and octocrylene, absorb UV radiation and convert it into heat, preventing skin damage.
Mineral filters, like zinc oxide and titanium dioxide, act as physical blockers, reflecting UV rays off the skin.
Each type has its benefits, and the choice often depends on the desired texture, protection, and customer preference.
Choosing the Right UV Filter for Your Formulation
Selecting the appropriate UV filter depends on whether it is oil- or water-soluble, as this influences the overall formulation.
At Zicail, we carefully evaluate each formulation to ensure the UV filters are compatible with the base, maintaining the right balance between protection and ease of application.
For example, oil-soluble filters require a stable lipid base, while water-soluble filters need suitable aqueous components to ensure smooth application and long-lasting protection.
Synergistic UV Filter Combinations for Optimal UVA/UVB Ratio and SPF
Using a combination of UV filters can enhance sunscreen performance.
At Zicail, we often blend filters to create a synergistic effect, optimizing the balance between UVA and UVB protection.
This not only improves the overall SPF but also ensures broad-spectrum coverage, protecting skin from both aging (UVA) and burning (UVB) rays, while delivering a light, pleasant texture for daily use.
Formulation Strategies for High SPF Products
Overcoming Challenges in Formulating SPF 50+ Products
Creating high-SPF sunscreens, especially those with SPF 50+, presents unique challenges.
As the proportion of UV filters increases, so do the difficulties in achieving a stable, aesthetically pleasing product.
At Zicail, we address these challenges by ensuring an even distribution of UV filters and maintaining product stability, which is critical for both efficacy and user satisfaction.
How the Proportion of UV Filters Affects Skin Feel and Aesthetics
Higher SPF requires a higher concentration of UV filters, which can lead to a heavier, tackier feel on the skin.
To counter this, Zicail formulators carefully balance UV filter levels with skin-smoothing ingredients to ensure that even SPF 50+ sunscreens feel lightweight and non-greasy, while providing maximum protection.
Pre-dispersed Powders and Coated UV Filters for Improved Texture and Performance
Pre-dispersed powders and coated UV filters are game changers when it comes to improving the texture and spreadability of high-SPF sunscreens.
These advanced ingredients allow for better distribution across the skin, minimizing the “chalky” feel often associated with high-SPF products.
By utilizing these innovative techniques, Zicail ensures that our sunscreens not only protect but also feel great on the skin, making them ideal for daily use.
