Shower gels, also known as shower creams or body washes, are liquid products used for cleaning the body during showers. They typically consist of water, betaines, and sodium laureth sulfate (SLS), along with synthetic detergents derived from petroleum or plant sources. The main difference between shower gels and soap is that shower gels do not contain saponified oil. They have a lower pH value than traditional soap, which is known to be less drying to the skin. Some common ingredients in shower gels include surfactants, thickeners, preservatives, and fragrances. Surfactants, which can make up as much as 50 percent of the shower gel content, are compounds that lower the surface tension between substances, helping to emulsify and wash away oily dirt. To prevent shower gel ingredients from separating, emulsifiers such as diethanolamine are added
. When it comes to the positive and negative aspects of shower gels, it's important to consider the ingredients. Common fragrance ingredients, such as phthalates and synthetic musks, can be toxic to human health. Additionally, some surfactants found in conventional shower gels, such as sodium laureth sulfate and sodium lauryl sulfate, have been found to cause contact irritation in users and are harmful to aquatic life
. In terms of materials, natural shower gels can be made using a combination of non-ionic surfactants, an amphoteric surfactant, and botanical additives. These ingredients, in precise ratios, create the foundation of a great shower gel that produces a good foam and cleanses well. Natural shower gels can also incorporate botanical extracts to add color to the product
. In summary, when choosing a shower gel, it's important to consider the ingredients and their potential impact on both human health and the environment. Opting for shower gels that disclose 100% of their ingredients, avoid toxic chemicals, and are biodegradable can help ensure a safer and more sustainable shower routine
