Process for treating hair with ionic oilin-water emulsions of polyorganosiloxanes

Claim 1

A METHOD FOR TREATING HAIR TO IMPROVE THE APPEARANCE, MANAGEABILITY AND SOFNESS OF THE HAIR CONSISTING ESSENTIALLY OF SUBMITTING THE HAIR TO THE ACTION OF AN IONIC OIL-IN-WATER EMULSION, SAID EMULSION BEING COMPOSED OF AN ORGANOSILOXANE IN AN AMOUNT OF FROM 0.01 TO 90 PERCENT BY WEIGHT BASED UPON THE TOTAL WEIGHT OF THE EMULSION AND AN IONIC EMULSIFYING AGENT IN AN AMOUNT OF FROM 2 TO 25 PERCENT BY WEIGHT BASED UPON THE WEIGHT OF THE ORGANOSILOXANE AND AN ALKALINE CATALYST IN AN AMOUNT OF FROM ONE ALKALINE MOLECULE PER 100 SILICON ATOMS TO ONE ALKALINE MOLECULE PER 50,000 SILICON ATOMS INCLUSIVE AND THE NECESSARY WATER TO GIVE THE DESIRED SOLIDS CONTENT; THE ORGANOSILOXANE BEING OF THE UNIT FORMULA RN-SI-O((4-N)/2) WHEREIN R IS SELECTED FROM THE GROUP CONTAINING OF MONOVALENT HYDROCARBON AND HALOGENATED HYDROCARBON RADICALS AND HYDROGEN, THERE BEING AN AVERAGE OF NO MORE THAN ONE HYDROGEN ATOM PER SILICON ATOM AND N HAVING AN AVERAGE VALUE OF FROM 1.9 TO 2.1 INCLUSIVE AND SAID ALKALINE CATALYST IS SELECTED FROM THE GROUP CONSISTING OF (A) R''4NOH AND (B) R''4NX ADMIXED WITH Q WHEREIN R'' IS ALKYL, X IS AN ACID ANION AND Q IS AN ALKALINE COMPOUND SELECTED FROM THE GROUP CONSISTING OF AMMONIA, ALKALI METAL HYDROXIDES, ALKALI METAL CARBONATES AND ORGANIC AMINES, SAID IONIC OIL-IN-WATER EMULSION BEING PREPARED BY POLYMERIZING THE ORGANOSILOXANE IN AN AQUEOUS MEDIUM IN THE PRESENCE OF SAID ALKALINE CATALYST UNTIL THE SILOXANE REACHES A MOLECULAR AGGREGATION OF BETWEEN 6.5 AND 2.5X10**6 CS. AT 25*C. SAID IONIC OIL-IN-WATER EMULSION CONTAINING AN IONIC EMULSIFYING AGENT.

Claim 2

A METHOD FOR TREATING HAIR TO IMPROVE THE APPEARANCE, MANAGEABILITY AND SOFNESS OF THE HAIR CONSISTING ESSENTIALLY OF SUBMITTING THE HAIR TO THE ACTION OF AN IONIC OIL-IN-WATER EMULSION, SAID EMULSION BEING COMPOSED OF AN ORGANOSILOXANE IN AN AMOUNT OF FROM 0.01 TO 90 PERCENT BY WEIGHT BASED UPON THE TOTAL WEIGHT OF THE EMULSION AND AN IONIC EMULSIFYING AGENT IN AN AMOUNT OF FROM 2 TO 25 PERCENT BY WEIGHT BASED UPON THE WEIGHT OF THE ORGANOSILOXANE AND AN ALKALINE CATALYST IN AN AMOUNT OF FROM ONE ALKALINE MOLECULE PER 100 SILICON ATOMS TO ONE ALKALINE MOLECULE PER 50,000 SILICON ATOMS INCLUSIVE AND THE NECESSARY WATER TO GIVE THE DESIRED SOLIDS CONTENT; THE ORGANOSILOXANE BEING OF THE UNIT FORMULA RN-SI-O((4-N)/2) WHEREIN R IS SELECTED FROM THE GROUP CONTAINING OF MONOVALENT HYDROCARBON AND HALOGENATED HYDROCARBON RADICALS AND HYDROGEN, THERE BEING AN AVERAGE OF NO MORE THAN ONE HYDROGEN ATOM PER SILICON ATOM AND N HAVING AN AVERAGE VALUE OF FROM 1.9 TO 2.1 INCLUSIVE AND SAID ALKALINE CATALYST IS SELECTED FROM THE GROUP CONSISTING OF (A) R''4NOH AND (B) R''4NX ADMIXED WITH Q WHEREIN R'' IS ALKYL, X IS AN ACID ANION AND Q IS AN ALKALINE COMPOUND SELECTED FROM THE GROUP CONSISTING OF AMMONIA, ALKALI METAL HYDROXIDES, ALKALI METAL CARBONATES AND ORGANIC AMINES, SAID IONIC OIL-IN-WATER EMULSION BEING PREPARED BY POLYMERIZING THE ORGANOSILOXANE IN AN AQUEOUS MEDIUM IN THE PRESENCE OF SAID ALKALINE CATALYST UNTIL THE SILOXANE REACHES A MOLECULAR AGGREGATION OF BETWEEN 6.5 AND 2.5X10**6 CS. AT 25*C. SAID IONIC OIL-IN-WATER EMULSION CONTAINING AN IONIC EMULSIFYING AGENT.
