Shampoos clear

Sodium lauryl sulfate is available in solution, paste, and soHd forms. As a solution its activity ranges between 28—30%, and as a paste it is 55% active. With this detergent in a shampoo, inorganic salts can affect viscosity. In addition, the limited solubiHty of sodium lauryl sulfate requires its judicious use in low cloud point clear shampoo systems. 

Ammonium lauryl sulfate [2235-54-3] is available as an approximately 28% active, clear, Hquid form. It has greater solubiHty than the sodium salt and is more likely to be used in formulating clear shampoos. Systems using this detergent show their best stabiHty at pH between 6 and 7. Lower pH would tend to hydrolyze the detergent, eventually releasing ammonia. 

Of the lauryl sulfates, the triethanolamine form has the best water solubiHty. Because of this, it is available from suppHers as a clear solution at an active concentration of 40%. Its main disadvantage is discoloration during storage, ie, yeUow to amber, which limits its use in clear shampoo systems. 

Other Additives. To provide and maintain the clarity of clear shampoos, the use of either ethyl or isopropyl alcohol maybe employed. Perfumes are added to make shampoos more pleasing in terms of odor, while dyes are incorporated to give visual aesthetics to the products. Salts of ethylenediaminetetraacetic acid are found to sequester and prevent formation of insoluble alkaline-earth metal salts. 

Castor esters have been found to be nonirritating and noncomedogenic to the skin. Cetyl ricinoleate was found to be an effective noncomedogenic moisturizer (118). Castor-based quaternaries prepared by reaction of a castor fatty acid and a tertiary diamine are used for hair care. The ricinoleic quaternium is incorporated into clear shampoo formulations for foam enhancement and conditioning (119,120).

Low levels of salt and free alcohol give maximum formulating flexibility. Low cloud point lends itself to sparkling clear shampoos, bath products and cleansers.

Alkyl Ether Sulfates These surfactants are also found in shampoo applications. They are prepared similarly to alkyl sulfates except that the fatty alcohol is first subjected to ethoxylation ethoxylation may range from 2 to 3 moles per mole of fatty alcohol. Lauryl alcohol is the typical fatty alcohol reacted. Because of high water solubility, alkyl ether sulfates have low cloud points, making them suited for clear shampoo formulations (5). Viscosities based on the ether sulfates can be easily controlled through addition of inorganic salts such as sodium chloride.
