Navigating the world of skincare ingredients can often feel like deciphering a complex scientific code. Among the most common terms you’ll encounter are surfactants, humectants, and petrochemicals. This blog aims to clarify what these terms mean and their function in skincare products, helping you make more informed choices about the products you use on your skin.
What are Surfactants?
Definition and Role:
Surfactants (Surface Active Agents) are compounds that lower the surface tension between two substances, such as two liquids or a liquid and a solid. In skincare, surfactants are primarily used to cleanse or emulsify, helping to mix oil and water ingredients and remove dirt and oils from the skin.
Types of Surfactants:
– Anionic surfactants: Common in cleansers and shampoos, known for their deep cleaning properties.
– Cationic surfactants: Often found in conditioners and skin softeners for their conditioning effects.
– Non-ionic surfactants: Typically, less irritating, used in various cosmetic products for their gentle nature.
– Amphoteric surfactants: Used in personal care products for their mild and non-irritating properties.
What are Humectants?
Definition and Role:
Humectants are ingredients that attract water from the surroundings, including the deeper layers of the skin or the air in a humid environment. They are used in skincare to hydrate the skin by preventing moisture loss and drawing moisture to the skin’s surface.
Common Humectants:
– Glycerin: A natural compound that draws water into the skin.
– Hyaluronic acid: Known for its capacity to hold up to 1000 times its weight in water, making it a super hydrator.
– Propylene glycol: A synthetic humectant used in a wide range of beauty products.
– Urea: Often found in moisturizers for its hydrating properties and ability to soften the skin.
What are Petrochemicals?
Definition and Role:
Petrochemicals are chemical products derived from petroleum, and some are also synthesised from natural gas or coal. In skincare, petrochemicals are often used as emollients, solvents, and preservatives. They can help form protective barriers on the skin and are often found in creams and lotions.
Common Petrochemicals in Skincare:
– Mineral oil: Used as a moisturizing agent.
– Paraffin: Creates a barrier that helps skin retain moisture.
– Propylene glycol: As mentioned, serves as a humectant and also a solvent in many skin care products.
Understanding the function of various skincare ingredients such as surfactants, humectants, and petrochemicals can empower you to choose products that align with your skin’s needs. Whether it’s selecting a deep-cleansing shampoo or a hydrating serum, recognising these components helps ensure that you are providing the best care for your skin.
