SLS is an abbreviation that stands for sodium lauryl sulfate. SLES is an abbreviation that stands for sodium laureth sulfate. Both chemicals are surfactants added to many health and beauty products to create foam and provide a cleansing action.
Sodium lauryl sulfate (SLS) is found in many everyday health and beauty products because it lathers to create a cleansing foam. Many hand soaps, face washes, shaving creams and even toothpastes owe their foaming quality to this compound. The use of this compound is considered safe by many regulatory agencies. However, this compound irritates the skin when left on the skin for a long time. People with sensitive skin or skin conditions such as dermatitis should avoid products containing SLS. Also, shampoos containing SLS are responsible for weakening the hair and causing hair loss. Because this compound stays in the hair follicles for a long time after washing.
Sodium laureth sulfate (SLES) is derived from SLS by the ethoxylation method. This process means that SLES is safe to use in bath and body care products and is gentler on the skin than SLS. Unlike SLS, sodium laureth sulfate does not aggravate the skin or remove excess moisture. Skin care products containing SLES are as cleansing, foaming and emulsifying as SLS, but leaving skin silky soft, smooth and nourished after use.
Briefly, both sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) can irritate the eyes, skin and lungs, especially with prolonged use. SLES may also be contaminated with a substance known to cause cancer in laboratory animals. This contamination occurs during the manufacturing process. Meanwhile, all sulfated products flowing into sewers can be toxic to aquatic animals. Many manufacturers are now opting for more environmentally friendly alternatives.
Many people today are against the use of consumer products containing SLS and SLES.
