PURITO - SPF and UVA protection [miscellaneous]

Beauty Tips For Body Care
I am trying to understand what is the deal with Purito and their sunscreens.They have two different sunscreensCentella Green Level Safe SunCentella Green Level Unscented SunAlthough they have the same two UV filters (one UVA filter and one UVB filter), the formulation is not the same. However, the company claims the exact same SPF and UVA PF results for both sunscreens: PPD of 22.59 and SPF of 84.5 (you can see the videos below). This is very strange as even if the exact same formulation is tested twice, we will not get the EXACT same results.Apart from the fact that they have used one set of results for both sunscreens, which is fairly suspicious, they have disclosed the percentage of UV filters used in their unscented formulation. According to their website: “The PURITO Centella Green Level Safe Sun contains 3% of Diethylamino Hydroxybenzoyl Hexyl Benzoate and 2% of Ethylhexyl Triazone.”This means that they claim an SPF of 84.5 just from 2% of a single UVB filter.Now in contrast to this sunscreen, we have the Invisible fluid (formerly known as the Shaka Fluid) from La Roche Posay. This sunscreen claims to feature a special technology to “gel and stabilize the droplets containing the filters, thus forming an extremely tight and protective structure”. With this technology on board, the company still uses a good amount of UV filters, namely Octisalate (5%), Uvinul T 150 (4.5%), Tinosorb S (4%), Avobenzone (3.5%), Mexoryl XL (2%), Mexoryl SX (0.495%).As in Europe any SPF above 60 can only be labelled SPF 50+, we can only learn more information about this product’s SPF from other countries. In Brazil, it is marketed as SPF 60 when they are able to market products with SPF 70 (https://www.laroche-posay.com.br/anthelios/hydraox-fluid-fps60). So I will assume it has an SPF of 60 - 70.So, La Roche Posay must use a special technology and 9.5% UVB filters and 6.495% of broad spectrum filters, i.e. a total of 16% of filters blocking UVB (8 times more filters) to get a lower SPF.Even the filter used by Purito at 2%, is used by La Roche Posay at 4.5%, i.e. more than double.Now for the UVA protection, La Roche Posay claim a PPD of 46 as opposed to 22.59, but still there, they use 10% of UVA filters as opposed to 3%. So, they are using more than 3 times the amount of filters to achieve double the PPD value.Is it possible that the formulation of the Purito is so special that they can use 8 times less filters to get a higher SPF???​Centella Green Level Safe SunWater, Butylene Glycol, Glycerin, Dicaprylyl Carbonate, Dibutyl Adipate, Diethylamino Hydroxybenzoyl Hexyl Benzoate, Hydrogenated Polyisobutene, 1,2-Hexanediol, Niacinamide, Ethylhexyl Triazone, Polyglyceryl-3 Methylglucose Distearate, Silica, Cetearyl Olivate, Cetearyl Alcohol, Centella Asiatica Extract (4315 ppm), Hyaluronic Acid, Tocopherol, Sorbitan Olivate, Glycery l Stearate SE, Methyl Glucose Sesquistearate, Sorbitan Stearate, Lavandula Angustifolia (Lavender) Oil, Disodium EDTA, Adenosine, Anthemis Nobilis Flower Oil, Caprylyl Glycol, EthylhexylglycerinPPD = 22.59 and SPF = 84.5https://www.youtube.com/watch?v=XZy0t_UCgNk​Centella Green Level Unscented SunWater, Butylene Glycol, Butyloctyl Salicylate, Glycerin, Diethylamino Hydroxybenzoyl Hexyl Benzoate, Hydrogenated Polyisobutene , Acrylates Copolymer, Silica , 1,2-Hexanediol, Niacinamide, Dibutyl Adipate, Ethylhexyl Triazone, Polyglyceryl-3 Methylglucose Distearate, Cetearyl Olivate, Cetearyl Alcohol, Dicaprylyl Carbonate, Sorbitan Olivate, Glyceryl Stearate, Methyl Glucose Sesquistearate, Sorbitan Stearate, Centella Asiatica Extract, Madecassoside, Asiaticoside, Madecassic Acid, Asiatic Acid, Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate, Disodium EDTA, Adenosine, Hyaluronic Acid, Caprylyl Glycol, Ethylhexylglycerin, TocopherolPPD = 22.59 and SPF = 84.5https://www.youtube.com/watch?v=jOQJzdQaiF4
