Is it true that shampoos without sodium lauryl sulfate don’t produce foam?
SLS has been used as an ingredient since 1930, commonly used as a cleaning agent in household disinfectants, laundry detergents or dishwashers, as well as in shampoos, body washes and toothpastes.
Today, sodium lauryl sulfate is frowned upon for unfounded reasons. There is a current narrative in which SLS is a threat to human health, with claims that it can cause cancer, hair loss, disrupt biological systems, etc. These claims are not scientifically supported and therefore should be considered false and misleading.
Why don’t we use it at Per Purr?
It turns out that SLS is a great inexpensive surfactant with a high cleansing capacity, and it also creates a rich foam. But it is not the best choice for everyone. Because of its strong astringent action, it has a more abrasive effect, which can cause irritation for some people. Today, there is a new generation of gentler surfactants with an excellent cleaning capacity.
Biotechnology allows these new cleaning agents, natural plant-based (surfactants), to perform their functions gently. This technology also means they are biodegradable, and all of their components are derived from renewable and sustainable natural resources (plant-based).
They say: “You don’t need foam to get a good wash.”
It’s true. But at Per Purr, we love foam and we don’t want to do without it. Foam is a fundamental part of a pleasant shower, helping to achieve a soft, silky and natural look.
SLS-free shampoos are known for not creating foam or lathering. At Per Purr, we use extremely mild sulfate-free surfactants (detergents) that provide a deep and long-lasting clean feeling, and create a rich, dense lather.
