The Sulphate-Free Trend: What and why?
By Dr. Kate Dudek
Sulphates are found in many cleaning products; from shampoos, to car wash soaps, to floor cleaners. Their main role is to create the ‘lathering up’ effect that rinses away dirt, grime and, in the case of haircare products, oils, which can leave the hair looking greasy and lacklustre.
No scientific studies have been able to substantiate the claim that sulphates cause cancer. However, they can cause irritation and it is recommended that they are used briefly, thoroughly rinsed from the skin and their concentration does not exceed 1%. One of the most commonly used sulphates in cosmetic products is Sodium Lauryl Sulphate, known as SLS. It is effective and economical, hence its widespread use in shampoos. However, it is a chemical and today, more than ever before, consumers are looking for more natural beauty products.
Sulphate-free alternatives are growing in popularity. Women today want products that are milder, gentler, and chemical-free. The Ozalys Gentle Shampoo contains two sulphate-free surfactants; decyl glucoside and cocamidopropyl hydroxysultaine. Decyl glucoside is a sugar derivative found in plants. Its gentle, non-irritant properties mean that it is an ideal addition to shampoo and it is particularly widely used in baby shampoo. It is fully biodegradable and the Cosmetic Ingredient Review (CIR) Expert Panel have concluded that it is safe for use in cosmetics and non-irritating to the skin. Cocamidopropyl hydroxysultaine is derived from coconut oil. It is mild, stable when used in combination with other ingredients and claims to have ‘foam-boosting’ properties. The CIR panel reports that this product is also safe to be used in cosmetics.
Ozalys’ products have been designed with women who have been affected by cancer in mind. Ozalys allows women to continue to care for themselves every day using products that innovate through their formulas, optimal absorption and packaging. Ozalys’ specially-formulated solutions are catered for physiological conditions that cause dermal sensitivity, or for the side effects of certain treatments that may result in olfactory and dermal ultra-sensitivity.
Ozalys’ personal hygiene, face and body care products have all been developed with the utmost care, minimising preservatives and excluding all substances suspected of being harmful to the body. Their highly soothing, moisturising and protective properties, as well as their delicate application and scent, turn daily beauty routines into moments of well-being and comfort.
