As the weather gets hotter, sunscreen cosmetics have become a high-frequency product used by consumers every day. Sunscreen "spray" cosmetics are increasingly favored by consumers because of their novel form and easy to use. So, what should be paid attention to when using sunscreen "spray" cosmetics, and is there a safety risk when using it improperly? Here, consumers are reminded to pay attention to the following three points:
1. What is sunscreen "spray" cosmetics?

According to the "Classification Rules and Catalogue of Cosmetics", cosmetics can be divided into dosage forms such as creams, liquids, powders, sprays, aerosols, etc., according to the classification of product dosage forms. The common sunscreen "spray" cosmetics on the market can generally be divided into two categories: spray form and aerosol form, the difference is whether it contains propellant or not.

Spray-type cosmetics do not contain propellants, and mainly rely on the pressure difference generated by the mechanical pressure pump to spray the spray, and the "mist" sprayed is generally large droplets (particles).
Aerosol cosmetics contain propellants, which mainly rely on the impetus generated by the propellant ejection from liquid to gaseous state when the propellant is sprayed, and the "mist" sprayed is generally smaller than the droplets (particles), and the packaging of such products is mostly metal cans.
2. Sunscreen "spray" cosmetics
Improper use is risky
✦
✦
✦
There are two main safety risks associated with the improper use of sunscreen "spray" cosmetics:
One is the risk of inhalation. When consumers use sunscreen "spray" cosmetics on their skin, they may inadvertently inhale the sprayed droplets, which may contain various cosmetic raw materials such as sunscreens, volatile organic compounds, fragrances, preservatives, etc., and when used intensively in small and confined spaces, such as in a car with closed windows, it may cause a large amount of inhalation in a short period of time, which may cause health risks, especially in children with allergies with high airway sensitivity, who are prone to induce severe coughing or wheezing attacks. Compared with spray-based cosmetics, aerosol-based cosmetics are relatively riskier to inhale when used due to the relatively smaller droplets sprayed.
The second is the risk of flammability and explosion. Because the propellant used in aerosol products may be flammable substances such as butane and propane, and is in a high-pressure state of liquefaction, it is prone to deflagration accidents when it encounters an ignition source. Therefore, sunscreen "spray" cosmetics need to pay attention to the issue of fire and explosion protection when using and storing.
3. How to use it correctly
Sunscreen "spray" cosmetics

01
Try to avoid inhaling the "spray". Use sunscreen "spray" cosmetics in well-ventilated areas, and do not use them in small, confined spaces such as cars and restrooms. When spraying, be careful to avoid the nose, mouth, eyes, and try to avoid inhalation. If a large amount of inhalation of "spray" cosmetics causes nasal pain and itching, pharyngeal discomfort, coughing, wheezing, chest tightness, etc., first of all, you should go to a space with air circulation in time, and clean the cosmetics to avoid re-contact. If you have a fever, or if symptoms such as coughing, wheezing, or chest tightness worsen, you should seek medical attention immediately.
02
Pay attention to store sunscreen "spray" cosmetics in a cool, dry and ventilated environment, avoiding direct sunlight; When using, it should be kept away from fire, heat source, static electricity, impact, etc., and avoid piercing the product or the used empty can or throwing it into the fire.
03
Avoid using sunscreen "spray" makeup on areas with skin abnormalities such as wounds, redness, swelling, or eczema.
