Oxy 40 Vol Developer 1 Litre

All hair and skin types.

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

People using permanent colour, lightening, or bleaching services.

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.

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

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

Those who prefer products with a creamy, uniform texture.

It is commonly used in conditioners and styling products to keep formulas consistent and easy to apply. It also supports even distribution of other ingredients through the hair.

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

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.

People living in hard‑water areas or those wanting formulas that rinse more cleanly.

Chelating agents can support the effectiveness of cleansing and conditioning products by preventing mineral build‑up. They are widely used at low levels to help maintain formulation clarity and consistency.

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

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.

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

Oily scalps, heavy product users and people who like a strong cleanse.

Useful for those who prefer haircare products with clear, consistent textures or evenly dispersed fragrance and oils.

It is widely used in shampoos, conditioners and styling products to keep formulations stable and smooth. It also offers mild surfactant properties that support product rinse-off.

A very common, well-tolerated humectant used across countless products.

People who enjoy a scented product.

Fragrance preference is personal. Some people prefer fragrance-free formulas by choice.

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

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.

Anyone using products that benefit from a long, reliable shelf life.

Propylparaben is a widely used preservative that helps maintain product quality and freshness. It is used at very low levels and is well studied for its role in keeping formulations stable.
