By following this link you will find an interesting development made by Laurence Coiffard and Céline Couteau on a particular ingredient, the boric acid. Long used in many preparations, it is one of the ingredients of the Bore derivatives family whose use is underestimate, but has involved many uses, particularly with the famous Cold cream.
You can read again this contribution on one of the star product based on boric acid, The Lotion Précieuse Dépensier, a very old product still on sale.
You will find the past and present uses of these derivatives in this Cahier: Cahier de la Cosmétothèque : les dérivés du Bore.
