Aerosol cans have been in use for nearly 200 years and are applied in many fields. So, how to choose the reliable aerosol can? The main factors to consider are as follows:

1.Stability/Compatibility

The most important factor for any aerosol can product is ensuring stability and reliability. Choose cans based on the type of product and the characteristics of the formula, and conduct compatibility and stability tests. Only with data support can we have a theoretical basis to bring the product to market. Of course, stability tests do not guarantee 100% no issues; they are only representative tests. There may be unknown issues in the future, but they can represent the vast majority of cases.

2.Safety

Safety is the primary consideration for any project. Here, safety includes user safety, pressure safety, environmental safety, toxicological safety, and the ratio of the full weight of the aerosol can’s contents. R&D engineers not only develop products that bring profit to the company but more importantly, products that are safe and beneficial to society.

3.User Comfort

After a product is produced and sold, it will ultimately be used by consumers. The comfort of use, ergonomics, spray effect, fragrance concentration, etc., all relate to the long-term viability of the product.

4.Cost-effectiveness

Excessive use of packaging materials is a waste of resources, so choosing appropriate packaging materials is a way to protect resources efficiently.

5.Aesthetic Appeal

Many consumers, especially in the cosmetics industry, are very focused on appearance. The first impression often determines the success or failure of a product. Therefore, during the R&D process, attention must also be given to the design of the appearance and the organic combination of the aesthetic needs of the target consumer group.

Finally, after understanding the relevant characteristics of aerosol cans, we should also know the following taboos for aerosol cans:

1.Chloride ions are the number one destructive molecule

Chloride (Cl-) has a small ionic radius, strong penetration ability, and can be strongly adsorbed by metal surfaces. Due to the adsorption effect, chloride corrosion can easily form pitting and eventually lead to perforation.

2.Strong Acidity

The ratio of contents to the full weight of the aerosol can

This ratio varies depending on the propellant used. Generally, it is recommended that the ratio does not exceed 85%.
