Description
' Patented Oct. 22, 1940 UNITED," STATES MANUFACTURE or A BASIS FOB FACE rownsn 'Mattl iias Quaedvlieg, Dessau in Anhalt, Germany,
assignor to.
Winthrop Chemical Company, Inc.,
New York, N. Y., a corporation of New York No Drawing. Application July 26, 1938, Serial No. 221,360. In Germany August 26, 1937 sciaims. (01. 167-92) As a basis for-face powder there have been used the zinc, strontium and aluminium salts of fatty acids of high molecular weight, for instance stearic acid and undecanic acid, also the fatty acid salts described in U. S. A. specification No. 1,995,663.- They have a good covering power, are strongly adherent and can be well rubbed in. As an extender for these-highly valuable materials talc and like earthy materials have long been used; these, however, possess in very low degree the good properties of the aforesaid fatty Y acid salts, apart from their capacity for being rubbed in.
This invention relates to the manufacture of bases for face powder by treating talc and similar earthy materials with a suitable fatty acid salt in molten or dissolved state. It has been found that in this manner the outstanding properties of the aforesaid fatty acid salts may be imparted to talc, kaolin, china clay or the like when the zinc, strontium and magnesium salts of higher fatty acids are used. When an aqueous solution is used, the talc, for example, is suspended in the 25 aqueous alkali soap solution and the insoluble metal salt is precipitated on the talc by adding a soluble metal salt, for instance zinc chloride, magnesium sulfate or the like. However, a better basis for face powder is obtained by treating 30 tale with zinc stearate or strontium undecanate in a suitable organic solvent, for instance, carbon tetrachloride, xylene, chlorobenzene or the like, if desired at a raised temperature. Talc thus treated has animproved covering power, a re-' 35 markable adherence and far excels a mechani cally made mixture of talc with zinc stearate for instance.
The following examples illustrate the invention: 1
40 Example 1.Into a solution of 20 parts of zinc stearate in 100 parts by weight of xylene are introdnced at 120 C. 100 parts of talc, and the whole is allowed to cool while stirring, then fil- 45 tered and the solid matter dried.
. mixed:
For making a high class powder there are Parts Talc treated as above '70 Titanium dioxide 3 Zinc oxide 20 Calcium carbonate 2 5 Magnesium carbonate 5 Example 2.-100 parts of talc are thoroughly stirred into a solution of 20 parts of sodium undecanate and 0.5 part of a preparation which is a condensation product of hydroxy-alkyl amine m with a higher organic'acid made as described in Canadian Patent No. 313,993 which corresponds with U. S. A. application Serial No. 340,015, filed February 14, 1929, by Ulrich and Nuesslein.
There is then run in gradually at 90 C. a solution of 6.6 parts of zinc chloride in.15o parts of water, the whole is stirred for a short time, filtered and the solid matter washed and dried.
In theforegoing examples use is made of zinc stearate and zinc undecanate. In the same manner the corresponding strontium or aluminium salts'of the said acids or the zinc, strontium or aluminium salts of any fatty acid having at least 10 carbon atoms in its molecule, may be used.
What I claim is:
1. The process for improving the covering power of talc powder when used as a basis for face powder which comprises treating the tale with a fatty acid metal saltv of the group consisting of zinc-, strontium-, and aluminium salts of fatty acids containing at least 10 carbon atoms said fatty acid metalsalt being in the liquid phase.
2. The process for improving the covering power of' talc powder when used as a basis for face powder which comprises treating the tale powder with a solution of a fatty acid metal salt of the group consisting of zinc-, strontium-, and aluminium salts of fatty acids containing at least 10 carbon atoms, and evaporating the solvent.
3. The process for improving the covering power 40 of talc powder when used as a basis for face powder which comprises treating'the talc powder with a melt of a fatty acid metal salt of the group consisting of zinc-, strontium-, and aluminium salts of fatty acids containing at least 10 carbon atoms.
