Description

(54) SHAMPOO COMPOSITION +71) We, S. C. JOHNSON & SON, INC., a Corporation organized and existing under the laws of the State of Wisconsin, United States of America, of 1525 Howe Street, Racine, Wisconsin, 53403, United States of America, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to an acidic shampoo composition. More particularly this invention relates to an acidic shampoo composition having improved cleaning.
Acid side shampoos, i.e. shampoos with with à pH of less than seven, have been known and in fact there are a number of shampoos currently on the market having a pH within the range of 5 to 7. It is known that high alkaline shampoos tend to damage hair and accordingly there has been a recent switch towards shampoo compositions which are less alkaline.
US. Patents 2,289,004, 2,303,932, 2,599,665 and 2,892,756 describe acid side slmmpoo hair treating compositions. These patents describe compositions having pHs with the range of from 2 to 7 and indicate that damage to the hair can be minimized by using a shampoo having a pH near the isoelectric point of hair, i.e. pH 4.5.
Also there are a number of patents and publications which describe the use of anionic detergents as the cleaning agent in the shampoo composition. The most commonly used anionic detergent is sodium lauryl sulfate. This detergent is an effective dealer for the hair and has reasonable solubility.
It has been found that an improved cleaning shampoo composition can be prepared by incorporating 12.5 to 25% by weight of an anionic detergent selected from the group consisting of M-lauryl sulfate, mixtures of M-lauryl sulfate and M-lauryl sulfate plus from 1 to 10 moles of ethyleneoxide and mixtures of M-lauryl sulfate and triethanola- mine lauryl sulfate wherein M is selected from sodium, potassium and ammonium, from 1.0 to 3.5% by weight of an inorganic salt soluble in the composition and from 0.25 to 1% by weight of an acid selected from citric acid, boric acid, hydrochloric acid, phosphoric acid, ascorbic acid and mixtures thereof, the composition having a pH within the range of 3 to 4.5 and a viscosity within the range of from 4000 to 15,000 centipoise at 20"C.
It is surprisingly found that the composi-tion having an increased viscosity performs significantly better than a similar composition having a lower viscosity and that compositions having lower pHs perform better than compositions having higher pHs, furthermore the compositions having lower pH and higher viscosity perform better than the similar compositions having either higher pH or lower viscosity. The improvement in performance appears to be synergistic since the combined effects of increased viscosity and decreased pH are exceeded by the composition having increased viscosity and decreased pH.
The prime cleaning component of the composition of the present invention is the anionic detergent. Anionic detergents useful in the present invention are selected from the group of M-lauryl sulfate, mixtures of M-lauryl sulfate and M-lauryl sulfate plus 1 to 10 moles of ethyleneoxide and mixtures of M-lauryl sulfate and triethanolamine lauryl sulfate wherein M is selected from sodium, potassium and ammonium. The total anionic detergent present in the composition in the present invention should be within the range of from 12.5 to 25% by weight and particularly within the range from 14 to 21% by weight anionic detergent.. When mixtures of M-lauryl sulfate are used with the other anionic detergents as described above, the mixture should be within the range of from 0 to 9 parts other anionic detergent per 1 part M-lauryl-sul- fate. The preferred M-lauryl sulfate for use in the composition of the pressent invention is ammonium lauryl sulfate.
The second component of the composition of the present invention is an inorganic salt.
The primary function of the inorganic salt is to provide free electrolyte which increases the viscosity of the composition. Within a certain range of inorganic salts, the viscosity of the composition increases, however, above or below the range, i.e. from 1.0 to 3.5% by weight. the viscosity of the resultant shampoo composition decreases. It is within this maximum range of viscosity that the performance properties of the shampoo are most surprising. Any non-toxic inorganic salt which is soluble in the composition of the present invention is suitable such as sodium chloride, potassium chloride, lithium chloride, ammonium chloride, sodium citrate, potassium citrate, lithium citrate and ammonium citrate. The preferred inorganic salts are ammonium chloride, sodium chloride and potassium chloride. The most preferred salt is ammonium chloride. As noted above, these salts may be present in a range of from 1.0 to 3.5% and is preferred that the salt be present in the range of about 1.4 to 2.75% by weight of the total composition.
The viscosity of the composition should be within the range of 4000 to 15,000 centipoise and preferably within the range of 5000 to 10,000 centipoise. The viscosity is measured at 20CC using a Brookfield viscometer equipped with a number LV4 spindle set at 30 RPM.
The third component of the present invention is an acidifying agent. The prime purpose of these acidifying or pH control agents is to lower the pH of the resultant composition. Although any suitable acid can be utilized to control the pH of the composition it has been found particularly acceptiblet to use the following acids: citric acid, boric acid, hydrochloric acid, phosphoric acid, ascorbic acid and mixtures.
These acids tend to have a buffering effect within the desired pH range when used in combination with the lauryl sulfate anionic detergent and the ionrganic salt. Although the exact amount of the acid is not critical, it is important to add sufficient acid to the composition so that the pH is maintained within the range of from 3 to 4.5 and preferably within the range of 3.3A.0. Generally from 0.25 to 1% by weight is satisfactory.
The bulk of the composition of the present invention comprises water. Substantially any water can be utilized in the composition although good manufacturing procedures require that the water be deionized and substantially free of major contaminants and impurities.
In addition to the above noted ingredients compositions of the present invention can include a number of other conventional additives including dyes, pigments, pearlessing agents, perfumes, preservatives and the like. These ingredients should be present in the composition preferably in combined amounts of less than 5% and in individual amounts of less than 2% each.
The composition of the present invention will now be illustrated by way of the following examples which are for the purpose of illustration only and are in no way to be considered as limiting.
EXAMPLE I A shampoo composition having the following composition was preparel: ammonium lauryl sulfate (28%) 60%, ammonium chloride 2.5%, citric acid 0.35%, fragrance 0.5%, formalin 0.134%, color QS, deionized water to 100%. The composition as prepared had a pH of 3.65 and a viscosity of 10,000.
Coiitparattive Examples I, II and III Compositions similar to the composition in Example I were prepared with the exeep- tion that the level of citric acid and ammonium chloride was varied as shown in Table I.
