Directions
Ingredients
  • Aqua Solvents
    Solvent

    The water base that carries and dissolves the other ingredients in most products.

    May suit

    All hair and skin types.

    Worth knowing

    Almost always the first ingredient listed in water-based products.

  • Hydrogen Peroxide Colourants
    Oxidising agent

    Used as an oxidising agent to lighten hair or activate hair dyes.

    May suit

    People using permanent colour, lightening, or bleaching services.

    Worth knowing

    It works by helping colour pigments develop or by lifting natural pigment during lightening. Formulations are balanced to achieve predictable results when used as directed.

  • Cetearyl Alcohol Conditioning agents
    Fatty alcohol conditioner

    A fatty alcohol that helps soften hair and improve the texture of formulations.

    May suit

    People looking for smoother, more manageable hair or richer, creamier product textures.

    Worth knowing

    Despite the name, fatty alcohols are moisturising and conditioning rather than drying. They also help stabilise and thicken many haircare formulas.

  • Mineral Oil Oils and butters
    Emollient / occlusive

    Helps smooth and coat the hair by forming a lightweight protective layer.

    May suit

    People looking to reduce moisture loss, add slip, or tame frizz.

    Worth knowing

    Mineral oil is a highly refined cosmetic-grade ingredient valued for its stability and ability to lock in moisture. It is commonly used in hair treatments and styling products for added softness and shine.

  • Ceteth-20 Cleansers / surfactants
    Emulsifier / solubiliser

    Helps blend oil‑ and water‑based ingredients to keep a formula smooth and uniform.

    May suit

    Those interested in stable, creamy conditioners and styling products.

    Worth knowing

    It is a non‑ionic surfactant commonly used to support texture and consistency in haircare formulas. It can also assist with light cleansing or dispersion of other ingredients.

  • Sodium Lauryl Sulfate Cleansers / surfactants
    Cleanser

    A cleansing surfactant that removes oil and build-up from the hair and scalp.

    May suit

    Oily scalps and routines that need a strong, clarifying wash.

    Worth knowing

    Can be more cleansing than gentler surfactants. Many people use it happily, while others prefer milder options for everyday washing.

  • Sodium Stannate Thickeners and stabilisers
    Stabiliser

    Sodium Stannate is used as a stabilising aid to help maintain the performance of certain haircare formulations.

    May suit

    People using peroxide-based hair colour or lightening products where stabilisers help keep the formula consistent.

    Worth knowing

    It appears most often in technical or professional products that require ingredients to support formula stability over time. It is typically used at low levels for functional support rather than for a direct effect on the hair.

  • Squalane Oils and butters
    Lightweight emollient

    Squalane is a lightweight emollient that helps smooth and soften the hair.

    May suit

    Those seeking added softness, shine and frizz control without a heavy or greasy feel.

    Worth knowing

    It is often derived from plant sources such as sugarcane and is valued for its stability and non-greasy texture. It is suitable for most hair types, including fine hair, due to its lightness.

  • Disodium Phosphate pH adjusters
    pH adjuster

    Helps maintain a stable pH level in a haircare formula.

    May suit

    Anyone interested in products formulated for consistent performance or stability.

    Worth knowing

    It is commonly used as a buffering agent to help keep a formula working as intended over time.

  • Phosphoric Acid pH adjusters
    pH adjuster

    Helps control and stabilise the pH level of haircare formulations.

    May suit

    Those interested in how products are balanced for optimal performance and scalp comfort.

    Worth knowing

    It is commonly used to fine-tune acidity so that formulas remain effective and comfortable to use. Only small amounts are typically required to achieve the desired pH.

  • Methylparaben Preservatives
    Preservative

    Helps protect haircare products by preventing microbial spoilage.

    May suit

    Anyone who wants products to stay fresh and stable over time.

    Worth knowing

    Parabens like methylparaben are widely used because they are effective in very small amounts and have a long history of use in cosmetics. They help maintain product quality, especially in water-based formulas.
