Compositions of benzene sulfonate quaternary ammonium salts of organic sunscreen carboxylic acids have substantially for human hair and protect it from the undesirable effects of sunlight.

Benzene sulfonate quaternary ammonium salts of organic sunscreen

Compositions containing an organic sunscreen and particular substituted cinnamal dialkyl malonate adjuvants therefor are very effective in providing broad spectrum sunscreen protection and skin care.

Substituted cinnamal dialkyl malonates in sunscreening, skin care

Non-polar cosmetic oil compositions containing a liquid cinnamal dialkyl malonate are very effective in providing broad spectrum sunscreen protection.

Liquid, cinnamal dialkyl malonates as sole organic sunscreens

Compositions containing an organic sunscreen and particular substituted dialkyl malonates adjuvants therefor are very effective in providing broad spectrum sunscreen protection.

Dialkyl malonates as organic sunscreen adjuvants

Novel compositions of matter consisting of benzene sulfonate quaternary ammonium salts have been found to be possessed of very good antistatic, emollient and substantive properties. They are prepared by reacting the amide or ester with the requisite sulfonate.

Benzene sulfonate quaternary ammonium salts

Compositions containing a benzalphthalide, i.e. benzalphthalide or a substituted benzalphthalide, are very effective broad spectrum sun screens. They are prepared by reacting substituted or unsubstituted phthalic anhydride with the corresponding substituted or unsubstituted phenyl acetic acid.

Benzalphthalides and broad spectrum sun screens

Novel compositions of matter consisting of fatty halo alkanoate quaternaries of dialkylaminopropylamides have been found to be excellent emollients having surprisingly good anti-tangle and anti-static properties in hair preparations. They are prepared by reacting the dialkylaminopropylamides with fatty halo alkanoate esters.

Novel compositions of matter consisting of amido propyl dialkyl amino beta hydroxy ethyl ammonium halides of mink oil have been found to be excellent emollients having surprisingly good hair conditioning properties. They are prepared for example by reacting either ethylene chlorohydrin or ethylene bromohydrin in a medium of water and propylene glycol, with an amide obtained by reacting, under anhydrous conditions, mink oil with either dimethylaminopropylamine or diethylaminopropylamine using an alkaline catalyst such as sodium hydroxide.
