This, invention relates to an improved hand cleaning composition. More particularly the invention concerns an improvedpenct rating and ingrained dirt removing com position of essentially unsaponified natural fats and oils in combination with other ingredients which will remove printers ink, deep ingrained grease, oil and dirt or cement dust from chapped hands and allows nature. to elfect a normal skin repair under clean and antiseptic conditions. As all laborers and mechanics are aware, grease and oil grime from mechanical labor becomes ingrained in the cracks and crevices of the hands and fingers. Normally a combination of saponified soap, detergent or solvent, as gasoline or the like, is used to, clean otf the oil and dirt. As

is generallyknown, such soaps detergents and solvents Accordingly, the principal object of this invention is to provide an improved skin cleaning and disinfecting composition which removes ingrained grease, dirt and oil grime from the cracks and crevices of chapped handswithout uncomfortable irritation to dirty open cracks in the skin. r I 7 Another object of this invention is to-provide an improved hand cleaning composition of strong cleansing action and yet of mild and soothing benefit to hands which have remained chapped and rough through'years of mechanical labor, as in automotive'repair work.=-

An additional object of this invention. is to provide a cleansing composition which can be lefton the hands or impregnated into gloves worn on the hands without irritation. r a Other objects and advantages will be apparent from the following description.

For those who only occasionally soil their hands with temporary light mechanical labor we have prepared a cleaning composition of the followingingredients:

3 Claims of application Ser..

FORMULA I Parts by weight Natural fats and oils 80.0 Bis-(2-hydroxy-3,5,6-trichlorophenyl)methane 0.8 N3-2C03.10H2O 3-5 Filler, inert material 15.7 Deodorant material 0.1

For those who regularly are employed in automotive or similar repair work and have the dirt and grime more deeply embedded in their hands, the following cleaning composition is preferred:

FORMULA II Parts by weight Natural fats and oils 80.0 Bis-(2-hydroxy-3,5,6-trichlorophenyl) methane 0.8 N3-2C03.10H2O Filler, inert material 0.2 Deodorant material 0.1

In Formula I, the bis-(2-hydroxy-3,5,6-trichlorophenyl) methane can be increased to 1.6 parts to provide a more bacteriostatic preparation. The hydrated sodium carbonate can be increased to 15 parts, or used in the range of about 0.5 parts to 25 parts with a relative addition or reduction in the filler and inert material. Also, the total base salt material as hydrated sodium carbonate can be entirely substituted for by, or combined in all percentages with, sodium tetraborate (Na O.2B O ;l0H O), or hydrated magnesium sulfate, or mixtures of the same.

In Formula II, the bis-(2-hydroxy-3,5,6-trichlorophenyl) methane can also be increased. to 1.6 parts to provide a more bacteriostatic preparation. The hydrated sodium carbonate can be increased to 25 parts, with relative and respective reductions of the natural fats and oil and for the filter and inert material portions. Again, hydrated magnesium sulfate and/or sodium tetraborate can be mixed or combined in all parts, or each substituted entirely for the hydrated sodium carbonate.

In preparing the above mixtures the natural fats and oils are thoseobtained from animal, vegetable, marine and mineral sources and of the character of semi-drying and non-drying fatty oil material in the form primarily of fatty acids and esters having chains of C to C unsaponified carbon atoms, including sterols. For example, the natural fats and oils may be those derived from bear,

swine, sheep, cattle, soy beans, peanuts, corn, olive,

whales, fish oils, and similar straight chain syntheticprodnets of petroleum and the like sources, as known to the art. Included in the inert material may be cellulose which may be natural cellulose or an organic short chain derivative, as methyl or ethyl cellulose and the like, or a sodium or potassium salt derivative of such, as is known to the art. The inert material may be added in about 0 to about 18 parts and is preferably added in the range of about 8.4.

parts to 18.7 parts in the form of a mild abrasive as fine sawdust, pumice, or other and like mild skin abrasive as is known to the soap making art. A small amount, upto about 1 part oil of cloves, or other suitable deodorant, or

ingredients soften the solid fat, keep it in soft and flexible condition for working with the hands and fingers as a cleansing composition. After proper working the dirt and cleaning composition can be easily washed off with warm water, or normal soap and water. Many have found it advantagcous to first clean their hands of cement dust, grime, or grease and dirt, then apply a light coating and wear gloves. This has afforded a soothing effect to badly cracked and chapped hands. Then, by keeping the hands clean with the above composition, they become relieved of the chapped condition.

Further, it has ben found that by covering the hands with a light coating of the composition, before work is begun, a faster cleaning results and hands that are normally in chapped condition are less subject to chapping.

For description of a specific and preferred formula, the fat is a mixture of solid and liquid animal glycerides, fatty acids, and their esters ranging from C3H7COOH to C3H5(OCOC15H3)(OCOC17H33)(OCOC17H35), the 311i mal cholesterol C H O, or sterols (cyclic alcohols). Such fats, as indicated, are preferably mixed in a fluid state With the balance of the composition components and forms a thick creamy mass ready for application and use. The proportions are as indicated in parts by weight. Otherwise the parts by Weight may be expressed in pounds or grams and calculated in percentage ratio for making any size batch desired.

Having thus described our improvement in hand cleaning compositions it will be apparent that the components may be varied slightly and substituted in the relationship described and embodied therein.

We claim:

1. A hand-cleaning skin-smoothing and chapped skinrelieving composition consisting essentially of a thick creamy mixture of about 80.0 parts of natural oils and fats; not more than 1.6 parts and not less than 0.8 part of bis(3,5,6-trichloro-2-hydroxy-phenyl) methane; not more than 25 parts and not less than 0.5 part of a basic salt selected from the group consisting of sodium carbonate decahydrate, sodium tetraborate and magnesium sulfate hydrate; not less than 0.2 part and not more than 18.7 parts of an inert material, employed as a filler and mild :4 I abrasive, selected from the group consisting of fine sawdust, pumicestone dust, cellulose, methyl. cellulose and ethyl cellulose; all parts being by weight and the parts totaling 100.00.

2. A hand-cleaning, skin smoothing and chapped skinrelieving composition consisting essentially of a thick, creamy mixture of about 80.00 parts of natural oils and fats; 0.8 part of bis(3,5,6-trichloro-2-hydroxy-phenyl) methane; 3.5 parts of sodium carbonate decahydrate; 15.7 parts of an inert material, employed as a filler and mild abrasive, selected from the group consisting of fine sawdust, pumicestone dust, cellulose, methyl celluloseand ethyl cellulose; all parts being by weight and totaling 100.00. a v

3. A hand-cleaning, skin-smoothing and chapped skinrelieving composition consisting essentially of a thick creamy mixture of about 80.0 parts of natural oils and fats; 0.8 part of bis(3,5,6-trichloro-Z-hydroxy-phenyl) methane; 10.0 parts of sodium carbonate decahydrate; 0.2 parts of an inert material, employed as a filler and mild abrasive, selected from the group consisting of fine sawdust, pumicestone dust, cellulose, methyl cellulose and ethyl cellulose, all parts being by weight.
