The lecithin and water were added to the composition when the temperature approaches 100 F. The coconut oil, monolaurin, cetyl esters, triethyl citrate, ethyl linoleate and bee's wax are next added. The mixture is heated and agitated until about 145 degrees F. and a shearing mechanism is activated and maintained until the mixture contains no grit. Next, stearyl dimethicone, zinc oxide and titanium oxide are added slowly and again the shearing mechanism is activated and maintained until the mixture contains no grit. The composition is maintained under agitation and heat is tuned off from the composition. Fragrance is added and the composition cools to about 125-130 F. The composition is agitated and sheared for a specified time dependent upon the size of the batch. After which time the lotion may be packaged.

[0017] Sunscreen Testing

[0018] The sunscreen formulation as presented above was tested for efficacy following an FDA protocol. Data from the testing is presented below in Table 2.

[0019] The Sun Protection Factor (SPF) of the test material when tested on ten subjects under static conditions yielded the mean SPF value of 34.57 and the label SPF of 33. The mean SPF of the 7% Padimate 0/3% Oxybenzone standard on the same panel was 16.79 and was within the standard deviation range of the expected SPF of 16.3+/−3.43.

[0020] A patch test was also performed for the sunscreen formulation presented above.

[0021] Subjects reported to the testing facility, at which time inclusion/exclusion criteria was reviewed and Informed Consent obtained. Upon verification of eligibility to enroll, the test articles were applied to the upper arm of each subject. The test articles were applied to the Webril□ disks according to a dose regime (see Section 5.1). The skin was marked with dots of crystal violet applied on either side of the top disk and below the bottom disk of the strip to enable exact location of subsequent patches. Each subject was asked to avoid the dye marks during washing and to keep the patches dry.

[0022] Subjects received patches containing the test article and two standard controls which were applied as 0.2 ml/0.2 g samples in one of five randomly assigned orders on the upper arm. The sample order for each subject was documented and maintained throughout the study in the form of a color-coded identification card. Subjects were instructed to keep the patches dry and in place for 23 hours then to remove and discard them and to return to the test center one hour later. Patches were applied on Days 1, 2, 3 and 4. Patches were applied to the same site on each day unless a reaction stronger than a mild erythema (i.e. greater than a score of 1.5 (Appendix 5)) was present in which case the patch strip was cut and the relevant patch (es) not reapplied. Assessment of patch sites was immediately before application of the next patch on Days 2, 3, 4 and on Day 5. After removal of the patches the test sites were wiped with a damp tissue to remove any remaining product.

[0023] The data from the testing is presented in Table 3 below.
