यसका साथै, सबै किसानहरूले साधारण हल गर्ने मेसिनको फाइदालाई महसुस गर्न सक्दैनन्। त्यहाँ आर्थिक संदर्भ र प्रविधिको पहुँचको कुरा पनि महत्त्वपूर्ण रहेको छ। सरकार र विभिन्न गैर सरकारी संस्थाहरूले किसानहरूलाई प्रशिक्षण र तिनीहरूको लागि सहुलियतमा पहुँच बनाउन मद्दत गर्नु आवश्यक छ।

  • On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].

  • Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.
