In this blog, we'll explore the diverse applications of empty aerosol cans.

In the Cosmetic and Personal Care Industry

Haircare Products

Hairsprays are one of the most common aerosol - based products.  They provide hold and volume to the hair.  The aerosol formulation allows for an even distribution of the product.  With a simple press of the nozzle, a fine mist of hairspray coats the hair strands, helping to keep the hairstyle in place throughout the day.  Styling mousses also come in aerosol cans.  These are great for adding texture and definition to the hair, making it easier to create different styles like curls or waves.

Skincare Products

Facial mists are popular among skincare enthusiasts.  Aerosol - delivered facial mists can provide instant hydration.  Ingredients such as hyaluronic acid, aloe vera, and various plant extracts are encapsulated in the mist.  When sprayed onto the face, it forms a light, refreshing layer that soothes and moisturizes the skin.  This application method ensures that the active ingredients are evenly spread across the face for maximum efficacy.

Deodorants and Antiperspirants

Aerosol deodorants and antiperspirants are widely used.  The spray mechanism allows for quick and easy application under the arms.  The formulation in the aerosol tin can contains substances that help control body odor and reduce sweating.  The fine spray covers a large area, providing long - lasting protection.

In the Household Cleaning Sector

Surface Cleaners

Aerosol surface cleaners are highly efficient.  They can be used on a variety of surfaces such as countertops, tables, and windows.  The pressurized system in the aerosol can enables the cleaner to be sprayed in a targeted manner.  The force of the spray helps to dislodge dirt and grime, making it easier to wipe away.  Different types of surface cleaners are available, including those for general cleaning and specialized ones for specific materials like wood or stainless steel.

Air Fresheners

Air freshener aerosol cans are essential for maintaining a pleasant indoor environment.  They come in a wide range of scents, from floral and fruity to fresh and clean.  The aerosol design allows the fragrance to be dispersed evenly throughout the room.  A quick spray can eliminate unpleasant odors and create a more inviting atmosphere in homes, offices, and public spaces.

Oven and Grill Cleaners

Cleaning ovens and grills can be a tough task, but aerosol oven and grill cleaners make it easier.  The strong cleaning agents in these aerosol cans are able to break down grease and food residues that accumulate over time.  The spray nozzle can be directed into hard - to - reach corners and crevices of the oven or grill, ensuring thorough cleaning.

In the Industrial and Automotive Fields

Paints and Coatings

Aerosol paint cans are widely used in DIY projects and small - scale industrial applications.  They are convenient for painting small objects, touch - ups, or creating decorative finishes.  The spray nozzle on the aerosol can be adjusted to control the paint flow and spray pattern, resulting in a smooth and even coat.  Industrial coatings in aerosol form are also used for protecting metal surfaces from corrosion.

Lubricants

Aerosol lubricants are invaluable in the automotive and mechanical industries.  They can be easily sprayed onto hinges, gears, and other moving parts.  The aerosol formulation allows the lubricant to reach tight spaces and provide smooth operation.  This helps to reduce friction and wear, extending the life of the equipment.

Adhesives

Aerosol adhesives are used in various applications.  In the packaging industry, they can be used to bond cardboard or paper.  In construction and DIY projects, aerosol adhesives can be used for quick and temporary fixes.  The spray - on adhesive provides a uniform layer, ensuring a strong bond between the surfaces.

Aerosol products, because of their ease of use and wide range of applications, are increasingly entering various industries and people's daily lives. Aerosol products are divided into tinplate cans, aluminum cans and plastic cans according to their packaging, among which tinplate cans are the most widely used and the phenomenon of corrosion inside the cans is also the most common. 

Every year due to corrosion caused by the leakage of aerosol products through the cans of the phenomenon occurred from time to time, the loss is huge, because of the complexity of the cause, the empty can manufacturers, filling manufacturers, businesses, users can not clearly define the responsibility, often can not be concluded, each assessed part of the loss of the matter, in fact, the corrosion of the aerosol can be prevented through the standardization of formulations, processes, and do a good job of stability testing.

1. Types of corrosion

(1) Even corrosion

Such as alkaline detergent and no internal coating of tinplate cans inside the tin-plated layer in contact with the complete de-tinning terminated.

(2) Pit corrosion and perforation

Localized dissolution of the metal leads to perforation.

(3) Fracture corrosion

Top, bottom cover and can body connection, easy to form a stagnant area, the contents of the existence of electrolyte concentration effect, easy to cause crevice corrosion. 

(4) Electro-coupling corrosion 

Can body of copper welding weld, due to the destruction of the tin layer, copper and iron electrode potential difference, in the presence of electrolyte, contact and produce galvanic coupling corrosion, although the weld has a complementary protective layer, but the electrolyte can arrive at the surface of the metal layer through the protective layer, the formation of corrosion batteries, resulting in corrosion.

(5) Stress corrosion

Forming deformation of the stress exacerbates the distortion, causing corrosion at the cracks, such as aluminum cans.

(6) Sub-membrane corrosion

Under the organic film or in the surface treatment film under the metal surface of the horizontal direction of the expansion of corrosion.

Formulator in doing product stability testing, less concerned about the above classification, generally according to the gas-phase corrosion, liquid-phase corrosion, gas-liquid interface corrosion to describe, and according to these three phenomena to select the appropriate corrosion inhibitor, adjust the formula.

2. from the formulation design to prevent corrosion of aerosol products

(1) tinplate cans for oil-based (solvent-based) aerosol products

General pure solvent-based formulations, no need to add corrosion inhibitors, corrosion will rarely occur, but there are exceptions, if the oil-based LPG pesticide batch leakage may be the cause of kerosene or LPG raw materials mixed with a trace amount of water, filling into the product, moisture to make some insecticidal active ingredient hydrolysis or kerosene impurity reaction, the precipitation of acid substances leading to corrosion of the can.

Solution:

① Measure the moisture content of the raw material, ensure that the moisture content is less than 100ppm.

② Add some water-soluble solvents, such as isopropyl alcohol, ethanol, etc. to disperse the trace water in the oily solvents and LPG, to prevent gathering and settling at the bottom.

 (2) Alcohol-based aerosol products in tinplate cans

Early air freshener formulations consisted mainly of flavors, anhydrous ethanol or isopropanol, LPG or DME. General. There is no need to add corrosion inhibitors to these products, and if 95% ethanol is used, 0.1% sodium benzoate can be added.

(3) Water-based aerosol products for tinplate cans

For tinplate cans without internal coating, general water-based products, the best PH control in 7.0 ~ 9.0, according to the functional requirements of the product, choose to add 0.1-0.2% of the gas-phase and liquid-phase corrosion inhibitors, such as sodium benzoate, sodium nitrite, triethanolamine, ammonia, phosphoric acid dihydrogen amine, morpholine and so on. The use and dosage of sodium nitrite should be carefully selected, as it may be counterproductive if there are ingredients in the formulation that oxidize sodium nitrite to sodium nitrate.

For tinplate cans with internal coating, the product PH should be controlled above 5.5, but not to use DME as the ejection agent, because DME will dissolve the internal coating, causing it to flake off and not play a protective role, and the flaking of the internal coating may clog the suction tube, resulting in the product can not be sprayed.

When the PH of water-based products>10 or even PH 12 or above, strong alkali will make its tinplate cans without internal coating of the internal tin layer dissolved, the cans show a grayish-black, we call it “passivation layer”, this phenomenon is called “de-tinning”, is when the tin is dissolved, exposing a dark gray film. This phenomenon is called “de-tinning”, is when the tin dissolution, exposing a dark gray film of tin-iron alloy FeSn2, and strong alkali further reaction iron passivation into black, to prevent further corrosion. When a passivation layer exists, the product rarely corrodes through the can.

 

Selection of high-quality qualified aerosol cans, aerosol valves is an important factor in preventing product corrosion, because the regular manufacturers of tinplate cans selected by the raw materials are more compliant, the process of making cans will be more stringent control of stamping, slicing, internal coating, can body welding, two volume sealing and other process quality, the production of tinplate cans in terms of pressure resistance, airtightness and corrosion resistance will be more secure.In mgaerosolcan, we offer high quality aerosol tin cans.

Why might you consider using aerosol packaging for your products? Well, there are plenty of benefits that make this type of packaging worth using. 

Ease of use: One of the main selling points for aerosols is the convenience of just aiming and pressing with a single finger.

Safety: Aerosols are hermetically sealed which means there is a less likelihood of breakage, spills and leaks. This also is an effective way to prevent product tampering.

Control: With the push button, the consumer can control how much of the product they want to dispense. This allows for minimal waste and more efficient use.

Recyclable: Like other aluminum packaging, aerosol cans are 100% infinitely recyclable.

Things to Consider with Aerosol Packaging

Depending on the product, it is important to determine the size and basic color of the container. For aluminum aerosol cans, the sizes range from 35mm-76mm in diameter and 70mm-300mm in height. The most common opening on the top of the can is one inch. As far as base coat color options, there are two, white or clear.

Once you determine the size and color coat options, you can determine how you’d like to decorate the can to match your product and brand. The decorating options available include brushed aluminum, metallic, high-gloss, soft-touch as well as embossed and textured designs. The shape is determined by the shoulder style, such as round, oval, flat/conical or soft/bullet.

One of the last things to consider is how much pressure is required for you to disperse the product from the valve. Your product filler or chemist should guide you on the pressure resistance required to ensure your product dispenses correctly.
