Abstract

A concentrate composition comprising: (a) at least 0.1 wt % of a surfactant compound; and (b) at least 10 wt % one or more ingredients selected from aldehydes, succinimidyl esters, chelating agents and amine salts of carboxylic acids.

Claims

1. A concentrate emulsion composition consisting of water and: (a) from 0.1 to 10 wt % of an amphoteric and/or anionic surfactant compound; (b) from 2 to 10 wt % of 2-hydroxyoctanal; (c) from 5 to 25 wt % of glutamic acid N,N-diacetic acid (GLDA); and (d) from 3 to 15 wt % of a triethanolamine salt of octanoic acid; wherein said emulsion composition is storage stable under ambient conditions for at least 48 hours without breaking down.

2. The concentrate emulsion composition according to claim 1 wherein the amphoteric and/or anionic surfactant compound is selected from the group consisting of sodium laureth sulfate (SLES), cocamidopropyl betaine (CAPB), and mixtures thereof.

3. The concentrate emulsion composition according to claim 1 wherein the amphoteric and/or anionic surfactant compound comprises cocamidopropyl betaine (CAPB).

4. The concentrate emulsion composition according to claim 1 wherein component (a) and combined components (b), (c) and (d) together are between 20 and 60 wt % of the composition.

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

6. The method according to claim 5 wherein the formulated composition is a hair care composition.

7. The method according to claim 6 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, semipermanent or permanent.
