Oxidation Stability of Cosmetics and Personal Care Products

When it comes to skincare, the longevity and effectiveness of personal care products and cosmetics depend on various factors, and one critical factor is their oxidation stability. Understanding oxidation stability helps ensure that the product maintains its efficacy, safety, and quality over time.

Oxidation occurs when lipids reacts with oxygen, causing chemical changes that can affect the product’s composition. The process leads to the degradation of the active ingredients and result in an unpleasant change in color, texture, or scent.

Why Oxidation Stability Matters

Preservation of Active Ingredients: Many cosmetic products contain active ingredients like antioxidants (e.g., Vitamin C or E), peptides, and essential oils. Oxidation can reduce their potency, making the product less effective over time.
Preventing Skin Irritation: Oxidized ingredients may become irritating or even harmful to the skin, especially if the cream has expired or been improperly stored.
Maintaining Appearance and Scent: A change in color or odor is often a sign of oxidation, indicating that the product is no longer as fresh or pleasant to use.

Factors That Affect Oxidation Stability in Cosmetics

Ingredients: Some ingredients, like oils are more prone to oxidation.
Packaging: The type of packaging plays a significant role.
Storage Conditions: Cosmetics should be stored in cool, dry places. Heat and humidity can speed up the oxidation process, reducing the shelf life and effectiveness of the product.
Preservatives: Some preservatives and stabilizers are included in formulations to improve the shelf life and combat oxidation, ensuring the product remains effective over time.

The Role of the VELP Oxitest in Assessing Oxidation Stability

To understand and monitor the oxidation stability of cosmetic formulations, VELP Scientifica provides the Oxitest reacotr, an advanced instrument designed to measure the oxidation stability of oils and fats, under controlled conditions.

The Oxitest uses accelerated oxidation testing by introducing oxygen into a sample under high-pressure conditions. This method allows manufacturers to simulate long-term exposure to oxidation in a short period.

By using the VELP Oxitest, manufacturers can better assess the shelf life and stability of their products, ensuring that they remain effective, safe, and free from unwanted oxidative damage. This data helps formulators make informed decisions about ingredient selection, packaging, and preservation strategies.

For instance, to improve oxidation stability in cosmetics is it possibile to use of antioxidants, a proper packaging and improve the formulation
