摘要:
Sunscreen products that do not require the use of organic, ultraviolet-absorbing agents are provided. Effective protection of the skin from ultraviolet light is attained by increasing the amounts of titanium dioxide and zinc oxide. To mask the excessive whiteness that would otherwise result from the oxides, the sunscreen products contain multilayer-type encapsulations containing pigments. Before use, the pigments are enveloped in capsules that muffle the pigments' color. When the sunscreen product is applied to the skin, the capsules break and the pigments are released to counter the excessive whiteness due to titanium dioxide and zinc oxide. Sunscreen product precursors, from which these sunscreen products can be generated by stirring, are also provided. A sunscreen product package contains the sunscreen product precursor and a stirring ball. A method of ultraviolet protection is provided by shaking the sunscreen product package and applying the sunscreen product thus generated to the skin.
