Definitions

  • the present invention relates to cosmetic skin lightening composition and in particular to a skin lightening composition that delivers immediate improvements in skin appearance by providing enhanced instant brightness/glow along with the effects of lightening the skin.
  • a tan is essentially the skins' way of increasing its defence against the onslaught of damaging ultra-violet. Tanning protects against sun damage principally by increasing the melanin content of the epidermis. Although more skin pigmentation improves sun protection, intentional UV induced tanning does not necessarily achieve an increase in protective pigmentation as an ultra-violet protective strategy.
  • Melanin which is basically responsible for skin pigmentation is synthesised by melanocytes, a cell type present at dermis-epidermis junction, from an amino acid tyrosine. Tyrosine is acted upon by an enzyme tyrosinase which is the key enzyme in melanogenesis.
  • the conventional skin lightening compositions are based on sunscreens which maintain skin colour against the ultra-violet light. They have been based on materials which absorb/block incident ultra-violet light of the wavelength which produces the tanning of the skin. Other approaches have been to use niacin/niacinamide or other skin lightening agents which are believed to control dispersion of melanosomes or inhibit tyrosinase. Sunscreens alone cannot lighten the skin significantly and their action on the skin is only to reduce the ingress of incident ultra-violet into the skin and is therefore effective only during the day.
  • GB 1 533 1 19 discloses a combination of niacinamide and a suitable mixture of UV absorbers which absorb in the UV range of 290 nm to 360 nm.
  • IN 169917 discloses the use of a silicone compound to synergistically enhance skin lightening benefits obtained from the combination of niacinamide and sunscreens.
  • Certain inorganic substances have also been proposed for use as sunscreens which physically block exposure of the skin to ultra-violet rays.
  • titanium dioxide having a very small particle size. This grade of titanium dioxide, designated as ultrafine TiO 2 , affords a good degree of sun blocking potential without causing any biological skin lightening effect.
  • IN 172889 discloses the use of titanium dioxide at levels from 3% along with octyl methoxy cinnamate to provide protection from excessive exposure to ultra-violet rays over a broad range of wavelengths in the UV-A and UV-B regions.
  • US 5 997 887 and US 5 997 890 disclose topical compositions comprising pigmentary grade particulate material such as titanium dioxide, with a particle size greater than 100nm to about 300nm along with an active vitamin B 3 useful for imparting an essentially immediate visual improvement in skin appearance.
