Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A method of cleansing hair which comprises adding to the hair sufficient water and a shampoo composition consisting essentially of an aqueous solution of from about five to about 40 weight percent of an alkali metal, ammonium, or mono, di, or triethanolamine alpha-olefin sulfonate prepared from at least one normal alpha-olefin in having from 14 to 18 carbon atoms and about two to about 15 weight percent based on the alpha-olefin sulfonate salt of a primary normal of 2-methyl alkanol having from 10 to 15 carbon atoms to result in a wet, creamy, stable lather upon manipulation; manipulating said hair containing the shampoo composition and water to produce a wet, creamy, stable lather and cleanse the hair of foreign matter; and water rinsing said foam and foreign matter from said hair.
Claim 2
Independent Claim
131 words
A method of cleansing hair which comprises adding to the hair sufficient water and a shampoo composition consisting essentially of an aqueous solution of from about five to about 40 weight percent of an alkali metal, ammonium, or mono, di, or triethanolamine alpha-olefin sulfonate prepared from at least one normal alpha-olefin in having from 14 to 18 carbon atoms and about two to about 15 weight percent based on the alpha-olefin sulfonate salt of a primary normal of 2-methyl alkanol having from 10 to 15 carbon atoms to result in a wet, creamy, stable lather upon manipulation; manipulating said hair containing the shampoo composition and water to produce a wet, creamy, stable lather and cleanse the hair of foreign matter; and water rinsing said foam and foreign matter from said hair.
Claim 3
Independent Claim
131 words
A METHOD OF CLEANSING HAIR WHICH COMPRISES ADDING TO THE HAIR SUFFICIENT WATER AND A SHAMPOO COMPOSITION CONSISTING ESSENTIALLY OF AN AQUEOUS SOLUTION OF FROM ABOUT FIVE TO ABOUT 40 WEIGHT PERCENT OF AN ALKALI METAL, AMMONIUM, OR MONO, DI, OR TRIETHANOLAMINE ALPHA-OLEFIN SULFONATE PREPARED FROM AT LEAST ONE NORMAL ALPHA-OLEFIN IN HAVING FROM 14 TO 18 CARBON ATOMS AND ABOUT TWO TO ABOUT 15 WEIGHT PERCENT BASED ON THE ALPHA-OLEFIN SULFONATE SALT OF A PRIMARY NORMAL OF 2METHYL ALKANOL HAVING FROM 10 TO 15 CARBON ATOMS TO RESULT IN A WET, CREAMY, STABLE LATHER UPON MANIPULATION; MANIPULATING SAID HAIR CONTAINING THE SHAMPOO COMPOSITIN AND WATER TO PRODUCE A WET, CREAMY, STABLE LATHER AND CLEANSE THE HAIR OF FOREIGN MATTER; AND WATER RINSING SAID FOAM AND FOREIGN MATTER FROM SAID HAIR.

Claim 7
Dependent Claim
18 words
A method of cleansing hair in accordance with claim 1 in which the alkanol is predominately 1-undecyl alcohol.
Claim 8
Dependent Claim
