(eta: not to nit-pick, but we ALL drive our cars on roads that test animals' intelligence to cross safely every day, but noone notices... we all visit doctors... they did dissect animals to 'test' before cutting a human open.... Have you ever taken medication... oh I could go on forever on a topic that never gets settled... I wish it were different, but it is what it is)[/quote]
I actually don't own a car and don't want to, but hitting an animal by accident and killing it instantly is *not* the same is breeding mutated animals, torturing them with unnecessary experiments, and killing them if the experiments don't. Animal testing is nowhere close to necessary or even accurate -- it's cheaper than the alternatives, that's all. Yes, I have disected cats and goats that have died of natural causes in school, but I would not have done it had they been killed or were they alive. I don't like to take medications and prefer natural remedies when possible, and I stay very informed about where my medicine comes from and boycot the companies I know to test on animals. Testing on animals in the medical field to save lives (like testing new treatments for cancer and AIDS) is way different than testing on animals for cosmetics, which is the reason I started making my own cosmetics and only buy from a couple of very select brands. I know you say "that's the way it is", but I really don't settle for that in my life. I never use anything that has exploited animals. It's very possible for day-to-day stuff as long as you're informed. I was just wondering if it was possible in preserving cosmetics. If not, I won't do it. I'm really sorry if I sound snippy, but it's an extremely important issue to me and it's not something I can dismiss as "the way it is". I'd really like to provide alternatives if I can, because a lot of people feel the way I do and work really hard to find ethical products. I never buy anything without making sure that none of the ingredients come from animals, and I never buy anything that I know that has been tested on animals. So I'm going to keep looking into this.
Anyway,
I have been reading about a preservative called Naturagard Ultra and I'm considering it. Since I haven't worked with preservatives before, I was looking for feedback on whether or not this seems like a good one to use in lotions and body sprays, since I am just learning and have no comparison to draw. Here is all the info I found:
Description
Naturagard Ultra™ a Natural Preservative
Previously marketed as Geogard Ultra. In order to avoid infringement of Lonza's Trademark Registration we have been asked to relabel this product.
INCI: Gluconolactone (and) Sodium Benzoate
ECOCERT certified
Green Code 3
Naturagard Ultra, is new product that meets the growing demand for alternative self preserving cosmetic preservatives. With growing concerns over traditional preservatives such as parabens, Naturagard Ultra provides a single solution to companies seeking alternatives to traditional preservatives. Naturagard Ultra’s global regulatory acceptance, broad-spectrum activity and multi-functionality means it can be utilized in a wide variety of cosmetic products like shampoos, lotions and skin creams. Unlike traditional cosmetic preservatives, Naturagard Ultra can be used in cosmetic products that are marketed in major markets around the world: Europe, Japan, North America and South America.
Naturagard Ultra helps prevent product spoilage by utilizing less aggressive: “Hurdle Technology.” Instead of a harsh, aggressive approach with bacteria and fungi, Naturagard Ultra primarily functions by creating a more hostile environment within the formulation for microbes to overcome. Potentiators within Geogard® Ultra help create such hurdles, increasing the self-preserving environment of formulations.
Naturagard Ultra also provides greater utility with its multifunctional action. Naturagard Ultra not only provides effective protection against product spoilage, but it can also increase the skin moisturizing capacity of the formulation.
Naturagard Ultra is accepted by ECOCERT as a preservative in certified organic cosmetics.
This is a natural preservative that is a combination of a naturally occuring food additive glucono delta lactone, derived from corn, and a food grade preservative sodium benzoate, the sodium salt of benzoic acid along with a trace amount of calcium gluconate as a processing agent. This preservative is excellent for challenging formulations that tend to separate after time and are affected by chemical reactions.Because it is provided in powder form it will not jeopardize stability like most of the other natural or alternative preservatives.
