In order to preserve the effectiveness of their active ingredients, certain cosmetics necessitate unique packaging. Specialized packaging options such as vacuum pumps, dark glass bottles, metal hoses, and ampoules are commonly utilized. These methods ensure that the therapeutic properties of the product are maintained, guaranteeing optimal results for the users.
Dark glass bottles:When cosmetics are exposed to ultraviolet radiation, their photosensitive ingredients can become ineffective or even harmful. For example, compounds like ascorbic acid, ferulic acid, vitamin A alcohols, and furanocoumarin are all sensitive to light and can easily degrade or become toxic. To prevent this from happening, cosmetic manufacturers typically use dark, opaque glass bottles to protect their products from light. Dark brown glass is the most common choice, and these bottles are often equipped with droppers for easy, hygienic use. By taking these steps, cosmetics companies can ensure that their products remain safe and effective for their customers.
To ensure that their functional ingredients retain their effectiveness, cosmetic brands that prioritize quality commonly package their products in dark glass bottles. This is because light exposure can have a detrimental effect on the raw materials and decrease their potency. By using dark glass bottles, these brands are able to maintain the efficacy of their ingredients, resulting in more effective skincare products for their customers.
It's important to acknowledge that dark glass bottles are not exclusively used for light protection purposes; in some cases, they are chosen for traditional or aesthetic reasons. Some cosmetic products don't contain ingredients that are sensitive to light, but brands still consider the customary use of dark glass bottles and droppers in medicine packaging. Additionally, in order to attract consumers, they may opt for such packaging.
Vacuum pump:While the dark glass bottle excels in shading properties, it falls short in providing adequate air insulation for certain components. It is not suitable for substances that require heightened air protection, such as ubiquinone and ascorbic acid for their anti-oxidation properties. Additionally, components prone to oxidation, like shea butter, should not be stored in such bottles.
When a product requires higher packaging tightness for its ingredients, a vacuum pump can be employed. Vacuum pumps commonly utilize AS materials, and their key advantage lies in effectively isolating the contents from the external atmosphere. The bottle of the vacuum pump contains a piston at its base. Upon pressing the pump head, the bottom piston moves upward, facilitating the outward flow of the contents. This action reduces the volume of the bottle, preventing any air from entering.
Metal hose:If the priority of a product’s composition is to have effective shading and insulation against air, such as substances containing high levels of vitamin A alcohol, it becomes necessary to use a metal hose instead of a plastic one. Typically, high-concentration vitamin A alcohol products are stored in aluminum tubes. Aluminum tubes offer superior airtightness compared to plastic materials, and they can effectively shield the contents from light and moisture, thereby providing better protection for the product's potency and effectiveness.
Ampoule:A recent trend in the cosmetics industry has seen the rise of ampoules as a popular choice for inner packaging materials. Known for their exceptional airtightness and safety, ampoules have made their way from the medical industry to become a go-to option for cosmetic packaging. These ampoules serve a crucial purpose in maintaining the freshness of active ingredients, as they are designed for one-time use only. By providing a barrier against air and pollutants, they ensure the utmost hygiene of the product. Furthermore, the use of dark-colored glass ampoules enhances their light-proof properties. This feature is particularly beneficial as it helps protect light-sensitive ingredients. Moreover, the adoption of aseptic filling techniques with disposable ampoules has enabled some products to be formulated without the need for preservatives. This innovation caters to the specific needs of consumers with highly sensitive skin or those who prefer to avoid preservatives in their skincare regimen. With the emergence of ampoules, a new era of packaging solutions is now available, offering consumers more choices that align with their preferences and skincare demands.
