درس7: انواع ترکیبات شوینده‌های فاقد صابون

    Detergent ingredients in cosmetics, often referred to as surfactants, are essential for cleansing the skin and hair by breaking down oils and dirt. Here’s a brief overview of commonly used detergent ingredients in cosmetics:

    1. Sodium Lauryl Sulfate (SLS)
    A strong anionic surfactant that creates foam and effectively removes oil and dirt. However, it can cause irritation and dryness, particularly for sensitive skin. SLS is widely used in shampoos and body washes.

    2. Sodium Laureth Sulfate (SLES)
    A milder alternative to SLS, it is ethoxylated to reduce irritation potential. It is frequently found in liquid soaps, shampoos, and bubble baths for its foaming properties.

    3. Cocamidopropyl Betaine
    A gentle amphoteric surfactant derived from coconut oil, used to reduce irritation in formulations containing harsher surfactants. It is commonly found in "sensitive skin" products and baby shampoos.

    4. Decyl Glucoside
    A nonionic surfactant made from sugar and coconut oil. It is extremely mild and biodegradable, suitable for sensitive or dry skin and used in natural and organic products.

    5. Sodium Cocoyl Isethionate
    Derived from coconut oil, it is a mild, anionic surfactant providing a creamy lather. It is often used in cleansing bars and sulfate-free shampoos.

    6. Sodium Lauroyl Sarcosinate
    A gentle, amino acid-based surfactant offering effective cleansing with low irritation potential. It’s a popular choice for sulfate-free formulations.

    7. Disodium Laureth Sulfosuccinate
   A milder surfactant with larger molecular size, reducing skin penetration and irritation. It is commonly included in cleansers for sensitive skin】.

    8. Polysorbates (e.g., Polysorbate 20, 60, 80)
    Nonionic surfactants used as emulsifiers and mild detergents in various formulations, especially in combination with oil-based ingredients

    9. Coco-Glucoside
    Similar to decyl glucoside, this nonionic surfactant is made from plant-derived sources, offering gentle cleansing suitable for eco-friendly and sensitive products.

    10. Lauryl Glucoside
    Another nonionic surfactant known for its excellent compatibility with the skin and its use in natural and hypoallergenic products.

    Detergent ingredients vary in strength, cleansing ability, and mildness, allowing formulators to create products tailored to different skin types and needs. For more details, you can explore resources like INCIDecoder or Cosmetics Info.
