A solar simulator with a 150W xenon lamp (Fytronix solar Simulator Sunscreen) provided a spectral output in the ultraviolet range.

The time between applying the product and irradiation was 15 min. 

Each of the six test sites (area of 5- 10 cm2) was exposed to UV illumination (Multiport Solar UV Simulator Model 601) for 45 or 60 sec with a progression of UV doses of 25% from (output to output). The minimal erythemal doses (MEDs) were estimated visually after 22~24 hr. of UV exposure by a dermatologist. 

MED (millijoule (mj) / cm2) for unprotected skin was determined for each volunteer. The SPF value of the test product was then calculated from the UV radiation dose required to produce MED of the protected skin and from the dose of UV radiation required to produce MED of the unprotected skin as follows: 

SPF=(MED (protected skin)(mj/〖cm〗^2))/(ED (protected skin)(mj/〖cm〗^2 )=

The minimal erythemal doses (MEDs) were estimated visually after 22~24 hr. of UV exposure by a dermatologist. 

MED (millijoule (mj) / cm2) for unprotected skin was determined for each volunteer 

The SPF number tells you how long it might take you to get sunburnt after applying it, versus not wearing any at all. As an example: if you can spend 10 minutes in the sunlight without burning, a lotion with SPF10 will multiply this "self-protection time" by 10 to equal 100 minutes.

SPF means Sun Protection Factor using this equation.

Take the time you would normally burn in the sun without protection, 20 minutes will normally produce redness on a light skinned individual.

Multiply this number by the SPF of your product.

Example: with an SPF 15 x 20 minutes of sun time = 300 … is how many minutes you can stay in the sun without burning. 300 minutes divided by 1 hour of 60 minutes = 5 hours of sun protection without a sunburn.

How SPF is determined ...

In a controlled indoor laboratory eliminating any effects of environmental change, e.g., wind, heat and cold, untanned test subjects are put through a two day test.

On the first day, the lower back is protected except for the test site and exposed to UVB light until mildly red.

On the second day, a sunscreen is applied to a new test site and exposed to UVB light until the same mild redness occurs.

The amount of time to achieve redness with the applied sunscreen determines the SPF. As people vary so will the sun protection of products…results vary with individuals.

We recommend a high SPF due to a study report of participants not applying enough sunscreen to reach the SPF level of the product. Higher SPF sunscreens only increase protection by 3% but you may achieve an SPF 15 if not applying enough SPF 30 sunscreen.  The risk is increased sensitivity to the larger amount of chemical ingredients if using a chemical sunscreen. 

2 minutes of casual sun a day at the end of one year = 2 full weeks of sunbathing.  Dermatology Times, 1992-94.

To get the SPF number, a simple formula is used. The number of seconds it takes a patch of skin to slightly redden when covered in sunscreen is divided by the number of seconds it takes to slightly redden when there is no sunscreen applied. Say it took 300 seconds for skin to burn with sunscreen, and 10 seconds to burn without it. 300 is divided by 10, which is 30. The SPF is 30.
