  • Publication number: 20160166628
    Abstract: The invention relates to a composition that provides enhanced macro/microcirculation when applied on skin or is ingested. This composition has applications in areas such as reduction of under-eye dark circles, scalp health, reduction in under-arm darkening when applied topically and provides reduction in cardiovascular diseases when ingested orally. The anti-inflammatory and skin health benefits including anti-aging and skin lightening benefits are achieved using a combination of extract of Rubia cordifolia and Butea monosperma.

  • Publication number: 20150010483
    Abstract: The invention relates to a photo-stable sunscreen composition comprising a sunscreen stabilizer. It is an object of the present invention to provide a highly photo-stable sunscreen composition preferably extractable from a natural material while ensuring prolonged efficacy of the UV-A organic sunscreen used therein. The present inventors have achieved this by including Tanshinone IIA which is a diterpenoid othroquinone, which is present in certain plants, to achieve the desired sunscreen stabilisation.

  • Publication number: 20120195840
    Abstract: The present invention relates to a personal care composition for topical application comprising selective fractions of natural materials having photoprotective and skin lightening applications. The inventors found that certain fractions of natural materials which are rich in anthroquinones or naphthaquinones e.g. those from the Rubiaceae family provide for enhanced broad spectrum photoprotection especially in the visible range while also exhibiting enhanced activity in a biochemical pathway viz. ty-rosinase inhibition which is indicative of improved skin lightening.

  • Patent number: 7999112
    Abstract: The present invention provides a reusable transition metal complex catalyst useful for the preparation of high pure quality 3,3?-diaminobenzidine and its analogues. The present invention also provides to a process for the preparation of a reusable transition metal complex catalyst. The present invention further provides a process for the preparation of 3,3?-diaminobenzidine (DAB) or 3,3?,4,4? Tetraminobiphenyl (TAB) using reusable transition metal complex catalyst. The high quality 3,3?-diaminobenzedine (DAB) and its analogues are prepared by coupling 4-halo-2-nitroaniline to 3,3?-dinitrobenzidine (DNB) using transition metals as catalysts followed by reduction of 3,3?-dinitrobenzidine to the corresponding substituted 3,3?-diaminobenzidine of formula 1 in high yields.
