This invention relates'to lotions for personal use and pertains particularlyto an improved creamy skin lotion. p

- The object of the invention is to provide 6 a lotion of .the usual desired creamy emollient type and which is new and advanta geous because of its permanent characteristics and its ability to retain its color and ing pectous substances from various sources have, when freshly prepared, a creamy appearance or a greyish white opaque appear: ance when in the bottle and many have a creamy consistency as contrasted to watery consistencywhen freshly prepared. It has been observed that suckpro'ducts deteriorate by aging-as evidenced by darkening, namely changing'from a cream color to a dirty grey,

' ao' and as evidenced by increased watery consistency as contrasted to the relatively thicker creamy consistency of the original product. Such deterioration renders the product undesirable both from the standpoint of the user and from the viewpoint of the seller, and the oods thus become unmarketable and shel -worn a positive financial loss. r

The present invention provides a creamy 40 emollient lotion which is peculiar-in that aging apparently does not reduce its vis cosity or darken it. -Thus, for example, af-

ter several years the product of this invention appears substantially unchanged wherej as previously known productshave darkened and become watery in a like period. -.The general features of the lotion of this invention include a creamy base of a'somewhat flocculent character to be used in a proper combination with water for applying to the skin medicants of. a cooling, and soothing nature, and also substances which improve goods constitute Tineture benzoin 20 parts LOTION. v 7

the texture or color. of the skin. The most. I

important of these'mat'erials is the base. For many years glycerine and perfumed water have been used but a creamy base which in itself has emollient pro' erties is a distinct improvement over a, gycerine and water mixture. Consequently various emulsoid .colloids such as agar-agar, tragacanth and other materials including pectous substances from various sources have been used to provlde the desired creamy base, but all of these materials have beenin various degrees subject to the above mentioned deterioration. In preparing the lotion of the present ins vention a particular pectin base is used,

namely lemon pectinand citrous pectins in substantially pure conditioifand to such ma terial may be added glycerine, soaps, oils,

emulsified oils, lanolin, almond oil, peach kernel oil, stearic acid, alkali stearates, al-

mond meal, and substances of similar nature that have an emollient action on the skin.

The invention is predicated on theuse of the'citrous'p'ectin which is in substantially pure. condition, indeed astonishingl as compared to other known forms 0 pectin- I and produced by other known processes. This peculiar pectin base has been proved susceptible 'to incorporation with other lotion materials and with the unexpected. result that the lotion has not deteriorated. The

fine particles and milky liquids. 'The ground washed pulp is run into wood tanks having false bottoms covered with filter cloth: 1000 A one per cent solution of sulphurous acid is added in sufiicient quantity to suspend the pulp and the mixture is brought rapidly to about 90 C. The mixture is held at this temperature for two hours and is drawn ofi through the false bottom, the pulp itself making a filter mat. A second or third extraction is made in the same manner. The combined extracts are filtered and the pectin solution, which usually contains about 5% pectin, is rapidly cooled and excess sulphur dioxide removed by passing it over a series of baflle plates asin an ordinary water cooling tower.

The solution is run into tanks of 7500 liters capacity and there precipitated by adding the proper amount of aluminum sulphate and ammonium. hydroxide. The ammonium hydroxide is first added and while being violently agitated the aluminum-sulphate is added rapidly, the contents of the tank is now violently agitated which whips air into the precipitate causing it to rise to the top C. and the dried pectin ground in a mill to 100 mesh. Theground crude pectin is I washed with alcohol and hydrochloric acid to remove the aluminum hydrate and then Washed with alcohol alone to remove the hydrochloric 'acid and aluminum chloride. The

alcohol is drawn off through a filter cloth and recovered bydistillation. The washed pectin is dried at a moderate temperature in a-vacuum oven and is then put through a screen for and packed for .market. The pectin-ma e in accordance with the is made up of aluminum sulphate 1'.3%, cal cium sulphate .8%, and silica and starch, protein and fiber, and also free fromthe usual citrous juices. In addition to the ash content there is an additional impurity totalling less than 2% and composed of small amounts of hydrochloric acid, citric acid, and sulphurous acid.

positions of other pectins now available on the market and which are chiefly made by extracting the material with acidified water, filtering and evaporation to drynessand subsequent grinding. Such methods give products which contain pectin but also contain large'amounts of impurities such as ash, protein matter, starchy matter, fiber and much coloring matter, all of which is. disastrous to lotion standards. It is quite possible that the citrous pectin of the present invention may contain other colloids in addition to pectin, but at present the nature and amount of such colloids is unmown.

In. contrast to the citrous pectin of the present inventionsome of the marketed pectin contains as much as 10% of impurities in the form of sodium chloride, calciumsulphate SiO silicates, coloring matter, starch, protein, and fiber.v

Just exactly what active element in the citrous pectin causes the product of the present invention to remain perfect for'years onger than lotions containing other pectin or containing gumsis not yet proved. Various explanations have been oflered but an exact and satisfactory solution to the problem has not yet been advanced.

Lemon materials have heretofore frequently been used in toilet preparations, but such use has included substantially the entire lemon including pulp, oil, starch, protein,
