In a typical lab you don’t often get much time to just play around. But you snatch the odd moment to indulge yourself from time to time, and I always enjoy spreading the emollient oils on my skin to get to know their individual characters and personalities. One long standing favourite is isopropyl myristate which has a soft silky feeling, a bit reminiscent of velvet.

Yesterday, we asked what your sunscreen questions were. Here is the answer to one of the questions asked:

Octocrylene has been evaluated by the FDA and is considered safe for use up to 10% in the forumla. The European Union has allows its use up to 10% in a formula and Health Canada allows a maximum use level of 12%

Preservation is a tricky business. All formulations that contain a large amount of water need to be preserved and all preservatives have some kind of drawback. Potassium sorbate has been used for a long time but has recently been very widely used in products that have some kind of natural story about them. How natural is it?

Calendula is most widely used for skin and digestive issues, but also for menstrual symptoms.

The use of such a wide range of teas in cosmetics has caused some confusion for the consumer and quite a bit of excitement for the cosmetic formulators and chemists.
