78.8g of water was then added to the solution under stirring (300 rpm) for an additional 5 min stirring. This was followed by the addition of the methyl paraben (0.2 g) and carbopol (1 g). This solution was then stirred for a further 10 min. The final solution was then neutralized by triethanolamine (about 10 drops) under stirring condition (500 rpm) to obtain the SP-ALC gel.
