Description
~lWQ44 This invention relates to an acidic shampoo compo-sition. More particularly this invention relates to an acidic shampoo composition having improved cleaning.
Acid side shampoos, i.e. shampoos with a 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.
U.S. Patents 2,289,004, 2,303,932, 2,599,665 and
Acid side shampoos, i.e. shampoos with a 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.
U.S. Patents 2,289,004, 2,303,932, 2,599,665 and
2,892,756 describe acid side shampoo hair treating composi-tions. 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 iso-electric 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 cleaner for the hair and has reasonable solubil-ity.
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 con-sisting 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 triethanolamine lauryl sul-fate 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 l:lOQQ44 acid, ascorbic acid and mixtures thereof, the composition hav-ing a pH within the range of 3 to 4.5 and a viscosity within the range of from 4000 to 15,000 centipoise.
It is surprisingly found that the composition having an increased viscosity performs significantly better than a similar composition having a lower viscosity and that composi-tions 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 de-tergents 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 g parts other anionic detergent per 1 part M-lauryl sulfate. The pre-ferred M-lauryl sulfate for use in the composition of the present invention is ammonium lauryl sulfate.
The second component of the composition of the pres-liOQ044 ent invention is an inorganic salt. The primary function of the inorganic salt is to provide free electrolyte which in-creases the viscosity of the composition~ Within a certain range of inorganic salts, the viscosity of the composition in-creases, however, above or below the range, i.e. from 1.0 to

The pre-ferred M-lauryl sulfate for use in the composition of the present invention is ammonium lauryl sulfate.
The second component of the composition of the pres-liOQ044 ent invention is an inorganic salt. The primary function of the inorganic salt is to provide free electrolyte which in-creases the viscosity of the composition~ Within a certain range of inorganic salts, the viscosity of the composition in-creases, however, above or below the range, i.e. from 1.0 to
3.5% by weight, the viscosity of the resultant sha~poo compo-sition decreases. It is within this maximum range of visco-sity 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 i~ suitable such as sodium chloride, potassium chloride, lithium chloride, ammoni-um chloride, sodium citrate, potassium citrate, lithium ci-trate and ammonium citrateO 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 lo O 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 mea-sured using a Brookfield viscometer equipped with a number ~V4 spindle set at 30 ~PM.
The third componen~ 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 composi-tionO Although any suitable acid can be utilized to control the pH of the composition it has been found particularly ac-ceptible 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 inorganic salt. Although the exact amount of the acid added is not critical, it is important to add suf-ficient 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 3.3 - 4Ø 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 ma~or contaminants and impurities.
In addition to the above noted ingredients composi-tions of the present invention can include a number of other conventional additives including dyes, pigments, pearlessing agents, perfumes, preservatives and the likeO These ingredi-ents should be present in the composition preferably in com-bined amounts of less than 5% and in indlvidual 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 il~ustration only and are in no way to be con-sidered as limiting.
