Sunscreen and Sun Safety Testing in Demand!

Laboratory screening for potential allergens, harmful chemicals, and product efficacy is critical for sun safety.

by | Jul 28, 2023

As the summer heat blazes on, more and more requests are submitted to Contract Laboratory for sunscreen and sun protection testing. It is extremely important to recognize the significance of sunscreen and overall sun safety, and rigorous testing of products to ensure their efficacy and has a significant impact on consumer skin health and overall well-being.

UV Ray Shielding

The sun’s ultraviolet (UV) rays can cause significant damage to our skin, and too much exposure can lead to sunburn, premature aging, and an increased risk of skin cancer. Sunscreen acts as a protective shield, blocking UV rays and safeguarding our skin from potential harm. However, not all sunscreens are created equal in this respect! Laboratory testing can accurately assess the SPF level of a product, revealing how long the product can shield our skin from UVB rays compared to unprotected skin. These tests help consumers make informed decisions about the appropriate SPF level for their skin type and sun exposure levels. Because of this, SPF testing is one of the most popular testing requests we receive at Contract Laboratories for sunscreen and SPF-rated products!

Evaluating Broad Spectrum Protection

Adequate protection against both UVA and UVB rays from the sun is essential to safeguard our skin from damage! Comprehensive Laboratory testing to verify a sunscreen’s broad-spectrum protection capabilities ensures that the product can effectively protect the skin from both short-term sunburns (UVB) and long-term skin aging (UVA).

Water Resistance and Durability

Nothing feels better on a hot summer day than jumping in the pool! However, non-waterproof sunscreen often loses effectiveness once the skin comes into contact with water. Contract Laboratory testing goes beyond SPF assessments, examining sunscreen products for water resistance and durability. This is particularly important for ensuring protection while enjoying water-related activities or even when perspiring during outdoor activities. Rigorous testing ensures that the sunscreen remains effective, even when swimming or sweating!

Safe Ingredients and Allergen Testing

Sunscreen laboratory testing is equally vital in evaluating the safety of ingredients used in the products, particularly when the product is intended for children, babies, or those with sensitive skin. Screening a product to check for potential allergens and harmful chemicals can ensure that it is safe for all demographics.

Contract Laboratory can also help with testing, analysis, assays, evaluations, examinations, inspections, and certifications of Sun-care, Sunscreen, and Sun Protection to standard test methods, procedures, or specifications such as:

  • ISO 12312-2:2015 – Eye and face protection — Sunglasses and related eyewear — Part 2: Filters for direct observation of the sun
  • ISO 12312-1:2013 – Eye and face protection – Sunglasses and related eyewear – Part 1: Sunglasses for general use
  • ISO 18861 – Cosmetics – Sun protection test methods – Percentage of water resistance
  • ISO 12312-2:2015 – Eye and face protection – Sunglasses and related eyewear – Part 2: Filters for direct observation of the sun
