This water soluble vitamin is used extensively in leave-on skin and hair care products.  It helps to bind water in the epidermis, hair cuticle, follicles and nails and therefore has a good moisturising effect that helps to soften and relieve dry skin.

It has anti-inflammatory properties and is thought to help stimulate the healing processes within the skin and thus is soothing and calming for sore, chapped skin.

It is particularly penetrative to hair so excellent in hair care products to help improve moisturisation, protect it from damage, increase lustre and manageability.  Can also help to soothe a dry, irritated, itchy scalp.

Usage: 3-6% in leave on products.

Other notes: Can become unstable above 50oc.  Add at the cooling phase.
