14. The concentrate composition according to claim 1 which comprises 0.5 to 5 wt % of a surfactant compound, from 2 to 10 wt % of an aldehyde, from 5 to 25 wt % of a chelating agent and from 3 to 15 wt % of an amine salt of a carboxylic acid.

15. A formulated composition comprising a concentrate composition according to claim 1 and one or more further components.

16. A method of preparing a formulated composition, the method comprising admixing a concentrate composition as defined in claim 1 with one or more further components.

17. A formulated composition according to claim 15 wherein the formulated composition is a hair care composition.

18. A formulated composition according to claim 15 which provides one or more benefits selected from the group consisting of increased gloss or shine, improved combability, improved strength, increased softness, reduced protein loss, improved thermal durability, increased chemical resistance, increased waviness and increased straightness; wherein the benefit may be temporary, semi-permanent or permanent.

19.-20. (canceled)

EXAMPLE 2

[0347] Formulations 1 to 9 were stored for 48 hours at 25 C. and visually assessed. A stable system was a clear single phase.

[0348] Formulations 1 and 2 were unstable after 48 hours whereas formulations 3 to 9 were all stable.

EXAMPLE 3

[0349] Formulation 7 was stored for 4 months under ambient conditions (20-25 C., 1 atm). It remained stable after this period.
