    May suit

    People looking for mild, low-foaming cleansers that are generally considered suitable for sensitive or dry hair types.

    Cleanser / foam booster

    A milder co-surfactant that helps cleanse, boost foam and soften the feel of stronger cleansers.

  • Cocamide MIPA Cleansers / surfactants

    A coconut-derived surfactant that helps boost foam and improve the cleansing performance of shampoos.

    May suit

    People who like a rich, stable lather in their cleansing products.

  • Hexylene Glycol Solvents

  • Linalool Fragrance ingredients
    Fragrance component

    A fragrance component found naturally in many flowers and spices.

    Worth knowing

    A fragrance component that must be listed separately on labels because a minority of people can be sensitive to it. Its presence is normal, required disclosure and is not a quality signal.

  • Benzyl Alcohol Preservatives

    May suit

    May suit

  • Limonene Fragrance ingredients
    Fragrance component

    A fragrance component that also occurs naturally in many citrus and plant oils.

    Worth knowing

    May suit

    Those seeking softer, more manageable hair or looking to support damaged or chemically treated hair.

    Worth knowing

    Its cationic (positively charged) structure helps it bind to the hair surface, enhancing slip and reducing static. Being hydrolysed means the protein fragments are small enough to interact more effectively with the hair.

  • Sodium Hydroxide pH adjusters
    pH adjuster

    Helps control and stabilise the pH of haircare formulations.

    May suit

    Those interested in how product pH affects scalp comfort or hair cuticle behaviour.

    May suit

    Those who enjoy subtly scented haircare products.
