I don't know anything about Lysolecithin, but here is a bit about Shea Butter. I don't know if this is a GOOD ingredient or not, but have seen it used in a lot of 'home' skin care products. It is sold bulk at my local co-op.
Shea Butter (Butyrospermum parkii)
COSMETIC PROPERTIES AND USES: Derived from the pressed nuts of the karite tree, in its unrefined form shea butter is a cream-colored, soft substance with a strong fragrance that's difficult to mask. If the scent displeases you, then purchase the white, refined butter. It will be firmer, but will have the same properties. Shea butter is a highly emollient, skin-softening additive in lotions, creams, body balms, and nail care and after-sun care recipes. It can even be used alone if desired.
