The conundrum of how to package product for consumers is something that takes great consideration. It becomes even more perplexing when you factor eco responsibility. We want our products to be safe and have confidence that they will stay as fresh as possible for an acceptable shelf life. But, for Très Spa, we want to balance it with our sense of stewardship for the world we live in.
While glass is the best (especially colored glass), it weighs a great deal more than plastic and I personally do not feel comfortable with glass in the shower or bathroom. So after much consideration, we choose to use both blue and green PET bottles and jars. The plastic is a good gas and fair moisture barrier, as well as a good barrier to alcohol and solvents. It is light weight, strong, and impact-resistant making it far more practical than glass.
The resin signature of PET is 1 making it one of the most favorable for recycling. The jars and bottles can be recycled and the materials used to make lining for handbags, polar fleece, and carpet fibers.
I did have a customer ask me if the plastic contained BPA. Typically plastic marked with a resin count of 1, 2, 4, 5, and 6 do not contain BPA. Resin counts or 3 and 7 may contain BPA. How do you know what the resin count is of the bottle? Look on the bottom for a stamp like this one;
So why colored bottles? Since we use pure plant based ingredients and only pure essential oils, we want to protect them for as long as possible. The color helps to block UV rays that can damage the plant based ingredients.
