Cosmetic jars a beautiful revolution

Posted On December 30, 2022

The goal of both the manufacturer and the marketer is to get customers interested in and excited about purchasing a skin care product by using eye-catching and informative packaging. The packaging of cosmetics must meet what specific purposes and requirements?

Choose a cosmetics jar container by wholesale products based on its kind, compatibility, usefulness, and ability to safeguard its contents.

The goal

The function and nature of the packaged item determine the optimal packing method. The benefits and drawbacks of using a particular container may vary depending on the specifics of each situation.

Products stored in cosmetics jar containers shown in the table are more likely to include preservatives because they are more likely to get infected with germs when exposed to air. For reasons of microbiology, these containers must be treated as jars, which are required to have the open jar mark. The number of months after opening the goods purchased from wholesale products, in this case, 3 M, is indicated by this consumer information sign. This a legal requirement, even though it makes no sense for airless dispensers to include the logo.

Attributes of the Medium

It is essential to consider not only the container’s primary function as well as its microbiological and physical properties but also the compatibility of its content with its container. However, stability tests are performed over a longer duration before the container material is employed. There are usually several materials that need to be considered simultaneously. Here’s an example: an airless dispenser may include a spring made of bare, zinc-coated, or laminated steel, as well as one or more kinds of plastic, flexible sealing gaskets (made of elastomers), and other components. The following examples show a few possible issues with various materials:

Plastics

The chemical makeup of essential oils determines whether or not they can dissolve polymers by diffusion. Even though polypropylene (PP) is one of the most durable plastics available, you’re better off going with another material like glass or ceramic if you’re still determining how sturdy it will need to be.

• Short-chained esters may be absorbed by many synthetic materials and have plasticizing effects.
• Plastics and sealing gaskets may absorb short-chain amphiphilic preservatives as well. Consequently, the product’s microbiological stability may deteriorate with time as the preservative concentration drops below the minimum inhibitory concentration.
• The double-walled jar is not meant to be a bluff packaging since the polypropylene inner jar offers more product durability than the harder styrene-acrylonitrile (SAN) outer jar, which is better suited for ornamental reasons (surface, imprint).
• Substances released into the filling material might cause plastics to embrittle. After a while, the outer wall of a double-walled jar containing a waterless substance may develop fractures.

Some recycled plastics may be tainted with chemicals that might irritate a user’s skin if they utilize the product. China-origin recyclates may include contaminants not disclosed in their specifications but present at concentrations below the product’s stated criteria.

Materials made of plastic may accumulate an electrostatic charge. It’s important to remember that they collect dust quickly while putting them away.

Elastomers (sealing gaskets) (sealing gaskets)

Depending on the material qualities and the filling substance, sealing gaskets may soak or shrink. As a result, a compatibility check is necessary for the contents and containers, especially when dealing with organic compounds with low molecular weights. Allergies are a potential risk while working with natural rubber (latex allergy).

Glass

• Affordable soft drinks Depending on the filler material’s buffering capacity, the aqueous media’s pH may rise due to the discharge of sodium ions from lime glass.
• The advantages of glass and ceramic containers include their complete resistance to gaseous substances like oxygen and water vapor. Conversely, synthetics are often porous. The direction of the diffusion is affected by the strength of the gradient in each direction. Glass containers are used to store oxygen-sensitive items that are filled under a protected gas environment.
• Remember that liposomes or liquid nanoparticles that get onto the screw thread of a pipette container with a rubber seal will function like ideal ball bearings. When the gasket is squeezed, it becomes strong enough to unscrew a tightly sealed container. Store the bottles vertically to prevent any spills that may occur if they were kept horizontally. Yet, there is a solution that could help: the containers should include fake “brakes,” or instead, projecting glass knobs.

Conclusion

Even though airless dispensers’ steel springs won’t touch the filling substance, they might rust in a warm, humid environment. In the presence of complexing agents, a chemical reaction between the metal and acidic components of the filling material is more likely to occur when using aluminum containers or aluminum tubes with non-resistant or damaged interior coating. Water-soluble aluminum compounds could then form.
