THINGS HAPPEN, COLORS CHANGE...

I absolutely love Sesame seed oil in soap. It gives wonderful lather but still feels moisturizing and conditioning. It's no wonder it has been used for healing skin conditions for thousands of years. Yet, I have been thinking of giving up on sesame seed oil in my soaps. I am suspecting that it contributes to the color change of the soap. I have two examples. What do you think about these?

Soap 1: Before
 Soap 1: After
Soap 2: Before
Soap 2: After

Here are some things I have considered:

Rancidity of the oils: The sesame seed oils of these soaps are from a different batch and both from the reputable supplier that has always delivered top quality oils. Therefore I think that the oil quality is not the cause for this.

Rancidity of the soap: Both soaps have been properly stored in a cool, dark and dry place. There is no scent of rancidness in either one of them. The change of color happened quite soon, about 10-12 weeks after the soap was made. Also, the color change does not look like soap gone bad.

Discoloring EO: The essential oils in Soap nr. 1 are palmarosa, rosewood and lemongrass. Soap nr. 2 is scented with bergamot, mandarin, coriander, sage, lemon, grapefruit and marjoram EO. The only thing common in these two EO blends is a high content of linalool.

Right now I'm pondering two options. Does the sesame seed oil itself make the soap change color? Or does linalool somehow react with the sesame oil causing this... Any suggestions?

  1. Boy, I'm not sure what is causing the change, but I really don't see a problem with how any of them look! If it's a superior, moisturizing recipe I wouldn't change it purely based on aesthetics -I think it's very attractive as is FWIW. :) ~Becky

  2. I agree. I've never soaped with sesame oil either, but neither one looks like a change for the worse!

  4. I use up to 5% of the light seasame oil in my facial soaps and have not had a problem with color changes or rancidity. I agree with your other readers, that your soaps look lovely..wholesome and very natural.

  6. Becky and Amy: Thank you so much, maybe I shouldn't change it after all. The recipe is really wonderful, I just can not control how the soap will look!

    Lori: Yes, it is weird and I am beginning to be obsessed to find out what causes this :)

    Cocobong: Thank you for the info. My recipe has 40% sesame oil so maybe I'll try different percentages and see if that has anything to do with the color change.

    Ambra: Thank you so much!!! I enjoy reading your blog as well :)
