Abstract

A compound of formula (I) wherein R 1 is a C 5 to C 39 alkyl or alkenyl group and R 2 is (c) wherein A is an anion.

First claim

The invention claimed is:

1. A compound of formula (I):

wherein R 1 is a C 5 to C 39 alkyl or alkenyl group and R 2 is:

wherein A is an anion.

2. A compound according to claim 1 which is lauroyl thiamine chloride.

3. A compound according to claim 1 wherein R 1 is a C 9 to C 15 alkyl or alkenyl group or mixtures thereof.

4. A method of preparing a compound of formula (I) according to claim 1 , the method comprising reacting an acid of formula R 1 COOH or a derivative thereof with a compound of formula R 2 H or a precursor thereof where wherein R 1 is a C 5 to C 39 alkyl or alkenyl group and R 2 is

wherein A is an anion.

5. A composition comprising one or more compounds of formula (I) according to claim 1 .

6. A composition according to claim 5 which is selected from a laundry composition, an automatic dishwashing composition, a hand dishwashing composition, a hard surface cleaner, a personal care composition or an animal hygiene composition.

7. A composition according to claim 5 which is an oilfield production chemical composition.

8. A composition according to claim 5 selected from an antioxidant composition, a food additive, a health supplement or a medicinal composition.

9. A composition according to claim 5 which further comprises one or more surfactants selected from anionic, cationic, non ionic or amphoteric surfactants.

10. A composition according to claim 6 which is a personal care composition.

11. A composition according to claim 10 selected from shampoo, a shower gel, a toothpaste, a moisturiser, a shaving foam or gel, a hand wash, a body wash, a bath foam, a bubble bath, a soap bar, a liquid soap; a toilet bar, a facial cleanser, a skin cleanser or a make-up remover.

12. A composition according to claim 5 which is of low irritancy to the skin and/or eyes.

13. A composition according to claim 5 further comprising a surfactant selected from alkyl or alkenyl sulfates, alkyl or alkenyl ether sulfates, taurates, isethionates, acyl substituted amino acids, sarcosinates, or sulfosuccinates.

14. A composition according to claim 5 which further comprises one or more of sodium lauroyl methyl isethionate, sodium cocoyl methyl isethionate and sodium oleoyl methyl isethionate.

15. A concentrated surfactant composition comprising a compound as claimed in claim 1 .

16. A method of cleansing the skin and/or hair, the method comprising contacting the skin and/or hair with a composition comprising a compound of formula (I) according to claim 1 .
