Several years ago, manufacturers have discovered that consumers wanted a convenient way to apply sunscreen, especially for areas difficult to reach to reach, and without the chaos. So the spray, known as system developers' bag-on-valve "was introduced in 2005.
Now almost all of these products provide comfort, but at what cost?
Sitting on a beach in Mexico recently, I saw a woman with the wind of me to apply with a spray of sunscreen. In the heat I was in the clouds of sprayFlowering of his skin, like many comic legends, and soon she smelled of about 12 meters downwind. And I wondered: at what price convenience?
Let us examine first the price of convenience. With the prices of Wal-Mart [06/06/10] The unit cost of Coppertone Sport Lotion 30, for example, is $ 0.99/oz during the spray version is like $ 1.31/oz, 32% more expensive on the shelf. Equating the private label version of the lotion costs $ 0.63/oz during the spray version is $ 0.83/oz, and 32%more. Would be to spray with 30 Coppertone Sport Lotion instead of saving $ 0.68/oz, essentially a 2-for-1 activities.
But what is decisive is the actual delivery of sun protection products sprayed on the skin or applied as a lotion. Scientific tests show that only about 50% of the aerosol adheres to the skin. Recalculating the actual cost per unit of income Coppertone Sport Spray $ 2.62/applied ounces, while the Equate version goes for $ 1.66/applied oz This makes the cost of sun protectiondelivered to the skin 165% more expensive than aerosols, rather than as a lotion. Surprisingly, you need to buy $ 21 worth of Coppertone Sport Spray apply what one 8 oz Tube Sports Equate lotion delivered directly to the skin, set-up fee of $ 16 for comfort. Perhaps makes things worse is the skin penetration of sunscreen deposited aerosols is low. Semi-occluded lotions can better ensure the active ingredients into the skin. The good news is that the SPF should test the playing field by assessing the levelreal effectiveness, if the tests are validated.
About the cost of delivery of the spray are more price / performance problems. Power Spray is based on a very volatile vehicle, such as alcohol, or dry skin that Sting and fuel. Finally, the range of spray clear is difficult to judge, while a lotion allows the display of the application and coverage. On the other hand, is another value the application of lotions that has added moisturizers, antioxidants,Humectants, emollients, vitamins and other products for skin protection. These other services should not be underestimated.
In addition to these practical considerations, the price / performance and the trade-off between benefits remain in these forms, the question of "security". Every time a jet can be operated their inhaled nebulized. In general, the smaller the diameter of the aerosol droplets transported deeper into the airways. Most spray nozzles produce large droplets much larger than the distributionsCutting diameter required to reach deep into the lungs (peak at 0.1uM). However, I would have preferred to restrict the use on the skin --- the eyes or respiratory tract.
The advantages include a spray delivery: comfort and has reached some areas unreachable by hand, without annoying and fast drying. Disadvantages: relatively high cost, questionable spotty coverage, the prohibition of use on the face, the skin of healthy ingredients and lack of exposure to aerosols. The biggest cost driver is likely to be thePacking, no alcohol and drugs.
We conclude that the benefits to consumers and added value in a conventional lotions and the price much, much less find real unity. Sun protection spray convenience value, trust and value. The best delivery system is a second person with good hands. Brands include Aveeno copy (J & J), Neutrogena (J & J), Banana Boat (Energizer), Bullfrog (Chattem / Sanofi), No-Ad (No-Ad), Hawaiian Tropic (Tan Research Labs), and brands.
