Sunlight influences not only our skin but also the quality of various cosmetic and personal care products. UV exposure may cause discolouration, decrease fragrance quality, reduce the stability of active substances, and shorten shelf life.
That is why the choice of an appropriate UV absorber for personal care products plays an important role in modern formula development.
Understanding the way UV absorbers function helps to comprehend why their presence in cosmetic formulas has become essential.
Importance in Modern Cosmetics
A UV absorber for personal care products is a special ingredient that absorbs harmful ultraviolet radiation, preventing negative effects on the formulation’s components. The main purpose of the addition of a UV absorber is not the protection of consumers’ skin but the protection of the formulation itself.
Many ingredients in creams, serums, lotions, and cosmetics degrade under UV exposure. Due to such factors as oxidation and decomposition, formulations can lose colour, smell, separate and become unstable.
By adding a proper UV absorber to the formulas, the manufacturer ensures the improvement of the product stability during production, transportation, storage, and consumer use.
How Do UV Absorbers Work?
UV absorbers absorb harmful ultraviolet energy and turn it into less harmful low-energy heat. This prevents UV radiation from initiating destructive chemical reactions in the product.
So UV absorbers help to:
- Ensure the formula stability
- Protect the ingredients
- Prevent discolouration
- Maintain fragrance quality
- Reduce ingredient oxidation
- Improve the consistency of the formulation
- Provide for the shelf life of the product
In many cases, UV absorbers collaborate with antioxidants, stabilisers, air-tight packaging, and opaque containers, providing extra protection from the influence of external factors.
Benefits of UV Absorbers in Personal Care Products
- Formula Stability Improvement
There are many cosmetic ingredients which are naturally unstable under repeated UV exposure. UV absorbers help to slow down this process, increasing formula stability.
- Shelf Life Extension
Consumers expect personal care products to maintain the intended properties until the expiration date. UV absorbers help to extend the shelf life of a formulation, reducing UV light-induced deterioration.
- Enhanced Colour Retention
Natural extracts, botanical ingredients, pigments, and cosmetic colourants can fade over time. UV absorbers help to preserve the initial colour of the formulation.
- Fragrance Protection
Fragrance molecules are often very unstable under UV exposure. Thanks to UV absorbers, the integrity of fragrance in the formulation is maintained for a longer period.
- Increased Consumer Confidence
Product appearance, texture, fragrance and quality provide a better consumer experience and increase the consumer’s confidence in the product.
Application Areas for UV Absorbers
These days, UV absorbers are widely used in the personal care industry. Their common applications are the following:
- Sunscreens
- Moisturisers
- Face creams
- Body lotions
- Hair oils
- Hair serums
- Hair conditioners
- Lip care products
- Anti-ageing creams
- Colour cosmetics
- Foundations
- BB and CC creams
- Facial serums
- Premium skincare formulations.
Factors to Take Into Account During Ingredients Selection
There are many technical factors which are taken into account while selecting the appropriate UV absorber.
They are:
- Compatibility with other cosmetic ingredients
- Solubility in oil or water phases
- Photostability
- Processing temperature
- Protection of the intended UV wavelength
- Packaging compatibility
- Stability test results
- Regulatory requirements in the intended market
Regulations on cosmetic ingredients also differ across countries and regions. Some UV absorbers may be approved in one country but limited, restricted, or prohibited in another. So manufacturers should make sure they comply with the regulations of the destination market before commercial production or sales.
Conclusion
Consumers expect personal care products to remain safe, attractive and effective from the first to the last use. Consistency in the formula is possible only when formulating with high-quality ingredients and using scientifically proven stabilisation methods.
An appropriate UV absorber for personal care products helps to protect formulas from UV degradation, maintain the quality and ensure the long-lasting performance of products.
