In the world of cosmetic formulation, the quest for effective antioxidants to combat oxidation and extend product shelf life is paramount. And while synthetic vitamin E may seem like an appealing choice due to its low cost and prevalence, a closer examination reveals its inadequacies in providing robust protection against oxidation.
Synthetic vitamin E, also known as dl-alpha tocopherol, may offer biological antioxidant properties, but it falls short when it comes to technological efficacy. Unlike natural mixed tocopherols, synthetic vitamin E lacks the diverse spectrum of antioxidant compounds found in its natural counterparts. Consequently, it fails to provide comprehensive protection against oxidation and may even compromise the stability and efficacy of cosmetic products over time.
Misconceptions surrounding the use of synthetic vitamin E in cosmetics
To set the stage, the term « vitamin E » encompasses a group of 8 naturally occurring analogues, divided into 4 tocopherols and 4 tocotrienols. Among the tocopherol family, we find 4 different isomers; alpha, beta, delta and gamma, whose antioxidant capacity is in the following order from lowest to highest:
alpha < beta < gamma < delta
However, both natural and synthetic vitamin E marketed as an ingredient refers exclusively to alpha-tocopherol, so its capacity as a technological antioxidant is very low, and its use is not recommended to extend the shelf life of cosmetic and personal care formulations.
In contrast, natural antioxidants derived from plant-based sources offer a multifaceted approach to combating oxidation in cosmetic formulations.
In this sense, natural tocopherols are mixtures of the 4 isomers, with much higher levels of beta, gamma and delta tocopherol, which are the most effective as a technological antioxidant, and therefore the most suitable ingredient to protect cosmetic products against oxidation.
Moreover, natural antioxidants offer the added benefit of consumer appeal, catering to the growing demand for clean, sustainable, and eco-friendly cosmetic formulations. With increasing awareness of the environmental and health impacts of synthetic ingredients, consumers are actively seeking products formulated with natural, plant-based antioxidants.
The role of natural antioxidants in cosmetic products
At BTSA, we understand the critical role that antioxidants play in preserving the quality and efficacy of cosmetic formulations. That’s why we’re committed to providing natural antioxidant solutions that not only meet the highest standards of efficacy but also align with the values of conscious consumers.
Our range of upcycled & plant-based antioxidants are designed to enhance and extend product shelf-life. They are the perfect choice to protect cosmetic & personal care formulations against oxidation.
- Bioxan T is our range of mixed tocopherols, available in concentrations from 30% to 90%.
- Tocobiol C Blends is our range of synergistic antioxidants based on tocopherols. They are combined with other antioxidants such as green tea extract, rosemary extract or ascorbyl palmitate to achieve a maximum antioxidant level in each application.
By harnessing the power of nature’s antioxidants, we empower cosmetic formulators to create products that not only beautify but also nurture and protect the skin.
In conclusion, while synthetic vitamin E may offer a cost-effective solution, its technological limitations render it inadequate for protecting cosmetic formulations against oxidation. For optimal results, cosmetic formulators should turn to natural antioxidant solutions, such as tocopherol blends and other plant-based antioxidants, to ensure the stability and longevity of their products. Explore our Bioxan T and Tocobiol C Blends to discover the transformative potential of natural antioxidants in cosmetic formulations.
