Detergents [Letter from A. G. Griffin]


The minimum percentage of free alkali in laundry soaps permitted in New Zealand is 0.015% and the maximum is 0.036%. Samples of sunlight soap which I have analysed have contained as much as 0.048% free alkali, being up to three times the permitted level.

For the benefit of readers who value their curly locks might I suggest that they treat with some caution the advice to use sunlight rather than shampoos on their" hair, because it may start falling out.

A.G. Griffiny
