Novel sunscreen compositions containing titanium dioxide having a particle size less than about 35 m.mu. and zinc oxide having a particle size less than about 50 m.mu. are described as well as methods of protecting the skin from damaging ultraviolet radiation.

Sunscreen compositions

Novel sunscreen compositions containing titanium dioxide having a particle size less than 10 m.mu. are described as well as methods of protecting the skin from damaging ultraviolet radiation.

2,3-dimercaptosuccinic acid and esters thereof are prepared by reacting sodium thiosulfate with acetylene dicarboxylic acid in the presence of a strong acid and subjecting the resulting alkylthiosulfate to an acid hydrolysis. The 2,3-dimercaptosuccinic acids and esters thereof are useful as an antidote for heavy metal poisoning.

Process for the preparation of 2,3-dimercaptosuccinic acid and its lower

Novel amphoteric and zwitterionic betaine compounds containing at least one anion having a phosphorus-oxygen-phosphorus bond and processes for their preparation are described.

Pyrophosphobetaines

Phosphobetaine Compounds of the formula: ##STR1## wherein A is selected from O.sup.-, OM and O--Y--R+

Imidazoline phosphobetaines

Detergent and cleansing compositions are provided containing a pyrophosphobetaine compound and preferably at least one other surfactant.

Detergent compositions

Novel bisquaternary ammonium compounds are described and exhibit utility as components in personal care products.

Bisquaternary ammonium compound

Phosphitaine compounds of the formula ##STR1## wherein R is an amidoamine reactant moiety and Y is hydroxyalkylene. The compounds are useful as surfactants.

Phosphitaines

An improved cleansing, foaming and nonirritating detergent and cleansing composition for personal care use is provided containing phosphobetaine surfactant or a phosphitaine surfactant as an active ingredient.

An improved non-irritating or low irritating detergent composition exhibiting good foaming properties is disclosed. The composition is a synergistic mixture of an amphoteric surfactant and a phosphobetaine or phosphitaine surfactant.

Phosphobetaine Compounds of the formula ##STR1## wherein A is selected from O.sup.-, OM and --O--Y--R+

Phosphobetaines

Mild cleansing compositions comprising at least one detergent and at least one alkyleneoxylated bisquaternaryammonium compound are described. Suitable bisquaternary ammonium compounds are represented by the formula ##STR1## wherein R is an aliphatic radical of from about 10 to about 26 carbon atoms, R' is methyl, ethyl, propyl or R, X is an anion, n is an integer from 2 to 3, and x is an integer of from 1 to about 30. Suitable detergents are anionic or amphoteric detergents. The addition of alkyleneoxylated bisquaternary ammonium compound to anionic and amphoteric detergents reduces the irritant properties of the detergents.

Mild cleansing compositions comprising an alkyleneoxylated bisquaternary

Aqueous depilatory compositions are made by complexing 0.2 to 0.8 Sn(II) with a polyhydroxycarboxylate anion having five to seven carbon atoms and four to six hydroxyl groups in a molar ratio from 2:1 to 1:2 at a pH from 12.8 to 13.3.

Alkali stannite depilatories

Mild cleansing compositions comprising at least one detergent and at least one alkyleneoxylated bisquaternary ammonium compound are described. Suitable bisquaternary ammonium compounds are represented by the formula ##STR1## wherein R is an aliphatic radical of from about 10 to about 26 carbon atoms, R' is methyl, ethyl, propyl or R, X is an anion, n is an integer from 2 to 3, and x is an integer of from 1 to about 30. Suitable detergents are anionic or amphoteric detergents. The addition of alkyleneoxylated bisquaternary ammonium compound to anionic and amphoteric detergents reduces the irritant properties of the detergents.
