In general, the Schwarzkopf Colour Freeze collection is formulated with a combination of gentle cleansing agents, conditioning polymers, amino acids, and pH-balancing ingredients to protect colour-treated hair and extend colour vibrancy. Core ingredients typically include water (aqua), mild surfactants for gentle cleansing, conditioning agents like cetearyl alcohol, behentrimonium chloride, and polyquaterniums to smooth and detangle hair, amino acids (such as wheat and soy derivatives) to strengthen the hair shaft, and pH adjusters like citric or lactic acid to optimise the hair’s acidity and “lock in” colour pigments. The range also contains lightweight silicones in leave-in sprays for added shine and softness, emollients like shea butter for hydration, fragrances, and preservatives such as sodium benzoate and potassium sorbate to maintain product stability. Overall, the collection is designed to cleanse, condition, and maintain colour vibrancy while protecting the hair structure and reducing fading.
