Definitions

  • UV ultraviolet
  • Solar UV radiation causes damage to cell membranes and the DNA molecules inside the cells. It also helps break down collagen fibers and elastin, which are proteins that are vitally important for maintaining the skin's structural integrity. UV radiation causes collagen to break down faster than with the normal aging process. Repeated overexposure to the sun causes a thickening of the skin that produces a tough, leathery skin and unsightly changes in skin pigmentation. Overexposure to the sun and its UV rays cosmetically harms the skin, causing freckles, wrinkles, premature skin aging, solar lentago, solar elastosis, and pigment coloration changes, among other skin blemishes. As people increasingly engage in the modern outdoor lifestyle, these health and cosmetic concerns become more urgent.
  • UVA rays which comprise approximately 90-95% of the sun's ultraviolet light, have a relatively long wavelength in the 320-400 nanometer range. UVA rays are not absorbed by the ozone layer and are the primary cause of initial stages of a tan. UVB rays, with medium wavelength of about 290-320 nanometers, are partially absorbed by the ozone layer and are the primary cause of a sunburn.
  • sunscreen products have been developed and widely used for protection • against UVA and UVB rays.
  • the skin-care market currently sells sunscreen products generally in two different forms: as chemical absorbers or as physical blockers.
  • Chemical sunscreens contain one or more UV absorbing chemical components such as abovenzone, octocrylene, benzophenones, salicylate, and cinnamates. Although they are effective in shielding the body against the sun's effect, they also cause adverse skin reactions. Some studies have also found that chemical sunscreens generate harmful free radicals and may actually increase the risk of cancer. Some commonly used chemical sunscreens also have strong estrogenic actions that may lead to complications.
  • physical blockers or inorganic sunscreens physically scatter and reflect UVB and UVA rays.
  • Physical sunblocks such as zinc oxide or titanium dioxide, are not absorbed by the skin and are not known to cause health complications.
  • sunscreen products can be difficult to apply over the whole body. Even when applied properly, it must be applied repeatedly and in ample amounts. Additionally, a sunscreen lotion may be uncomfortable for some because of the oily/greasy feel it may leave behind. Thus, there is a need for a product that allows its users to apply sunblock on a daily basis in a convenient and easy manner.
  • the skin is also the body's largest organ.
  • the epidermis which is the outermost layer, functions primarily as a protective barrier, while the dermis is the underlying layer.
  • the skin provides the vital function of protecting the body against physical and chemical elements.
  • the blood vessels in the skin also regulate body temperature, and the skin functions as an important sensorial tool.
  • the skin In addition to providing protection and regulating the body, the skin also functions as a shock absorber and an insulator. No matter the age or skin type, proper skin care also involves proper cleaning, nourishing, moisturizing, and protecting. A good cleanser or soap rids the skin of the dirt and pollutants that accumulate over the course of a day without causing drying or adverse reaction.
  • the skin also needs to be nourished with nutrients and moisturizers.
  • the skin As an active organ, the skin is also susceptible to damages and ailments. Sunburns caused by overexposure should be treated promptly. Likewise, skin conditions such as eczema, acne, irregular pigmentation and the like should also be treated. Thus, there is a need for a skin product that simultaneously provides therapy and maintenance for healthy skin. Thus, there is a need in the art for an improved skin cleansing composition that safely washes and therapeutically treats the skin, while applying sunblock through the normal use of the soap.

Titanium dioxide and zinc oxide are well known physical UV blocking pigments. Titanium dioxide and zinc oxide are both very gentle on the skin. Zinc oxide, for example, is often used to treat diaper rash in infants and is a known therapeutic agent for the skin. Physical sunblocks such as titanium dioxide and zinc oxide differ from chemical sunscreens in that they are not absorbed by the skin, but rather lie on top of the skin and prevent the UV rays from reaching the skin.

  • Microfine zinc oxide provides stable and effective protection against ultraviolet radiation. Zinc oxide provides protection against UVB and UVA uniformly protecting from 290 to 380 nm. ZnO does not react with organic sunscreens when irradiated. Additionally, Zinc Oxide also gives the soap composition of the present invention anti-inflammatory qualities and helps calm irritated skin. Furthermore, ZnO also renders the inventive composition a skin protectant and wound healing adjuvant. Because ZnO is not absorbed into the body, it can safely be used with causing side effects.

Classifications may be High, Moderate, or Minimal. Because only five test panelists were included in this study, no PCD was assigned.
