Pl tell me a brandname of toothpaste available in India free of Sodium Sodium Lauryl Sulphate(SLS)?

My mom is suffering from recurring mouth ulcers. Frequent visit to doctors only gives temporary relief. From the net I've come to know that Sodium Lauryl Sulfate (SLS), an additive which is used almost all the common brands of toothpastes to generate 'foams' act as an 'trigger' to recurring mouth ulcers. Can anybody p me a brand name of toothpaste available in India free of Sodium Sodium Lauryl Sulphate(SLS)? Thanks!
