Every margarine / fat spread contains antioxidants which help them not to get rancid over time. Back in 2011 Astra contained an antioxidant in the formula called TBHQ (E319). This was an approved antioxidant under the Sri Lankan food regulation and was not a harmful ingredient. But did not come under the foods for infants and young children. This was picked up by the PHI and requested Astra to state in the labelling as "Astra is not suitable for children below 3 years".
But upon this the company, decided to remove this antioxidant completely from the product with immediate effect. There after Astra was not having this ingredient in the product and this was replaced by a natural ingredient in the name of Rosemary extract which is stated in the ingredient panel. Rosemary extract is approved by the Food Advisory committee as an ingredient that is good for everyone in the family including infants and young children. Upon the change Astra was approved and endorsed as a product suitable for everyone in the family.
