Q. Is GreenTerpene open to the public?

A. Yes, GreenTerpene is open to the public. Household and institutional users alike may purchase GreenTerpene Cleaning Products directly from our website GreenTerpene.com



Q. What is
GreenTerpene d-Limonene?

A. When pressing an orange for juice, some orange oil is also expelled. The GreenTerpene Orange Oil is then purified to produce GreenTerpene Food Grade & High Purity d-Limonene.

GreenTerpene Cold Pressed Orange Oil contains a between 90.0% to 95.0% d-Limonene. GreenTerpene  Food Grade d-Limonene contains a minimum of 95% d-Limonene and GreenTerpene High Purity d-Limonene contains a minimum of 98.5% d-Limonene. It may not sound like much, but 3.5% makes for a much more effective cleaner and is even necessary in some situations.



Q. What does natural mean? Are GreenTerpene products 100% natural?

A. Currently, there is no industry standard definition for natural cleaners. Our goal in developing the entire line of GreenTerpene natural cleaners is to use only materials that are renewable and efficacious. That's why our d-Limonene is extracted solely from domestic Florida oranges. And since it's 100% natural, it's better for the environment too.



Q. Do GreenTerpene products disinfect?

A. Not yet. But our scientists are focused on evaluating the disinfecting power of natural ingredients. We hope to incorporate disinfecting claims into GreenTerpene products in the future.



Q. What's the difference between GreenTerpene Cold Pressed Orange Florid Oil and GreenTerpene Food Grade or High Purity d-Limonene a.k.a. Orange Terpenes?

A. The difference between Cold Pressed Orange Oil and Food Grade or High Purity d-Limonene is the level of processing, and ultimately, their d-Limonene content. During orange juice extraction, Orange oil is the first product extracted from the orange peel, then Food Grade & High Purity d-Limonene are extracted from the Orange Oil.



Q. What is the difference between GreenTerpene Food Grade and High Purity d-Limonene?

A. Once extracted, the Food Grade d-Limonene contains a minimum of 95.0% d-Limonene. Then it is further  purified by high vacuum distillation to produce high purity d-Limonene, which contains a minimum of 98.5% d-
Limonene. It may not sound like much, but 3.5% makes for a much more effective cleaner and is even necessary in some situations.



Q. Why should GreenTerpene d-Limonene be diluted with water?

A. GreenTerpene d-Limonene and other terpenes alike are very powerful cleaners. Some applications will require that you use our product undiluted, while many will require about 1 part d-Limonene to 20 parts water.



Q. How much d-Limonene does GreenTerpene Cold Pressed Oil Contain?

A. GreenTerpene Cold Pressed Orange Oil contains a between 90.0% to 95.0% d-Limonene. GreenTerpene Food Grade d-Limonene contains a minimum of 95% d-Limonene and GreenTerpene High Purity d-Limonene contains a minimum of 98.5% d-Limonene. It may not sound like much, but 3.5% makes for a much more effective cleaner and is even necessary in some situations.



Q. Are GreenTerpene cleaning products soluble in water?


A. GreenTerpene Products do not contain any emulsifiers, surfactants, or soaps, and therefore are not soluble in water. All GreeneTerpene Products are 100% pure, natural, and additive free. GreenTerpene Products such as d-Limonene are most effective when used without an emulsifier or surfactant, and blended straight with water. Just add a small amount of terpenes to tap water in a PET spray bottle, agitate by shaking, and the terpenes will suspend temporarily. Shake as needed.



Q. Can GreenTerpene d-Limonene or GreenTerpene Orange Oil be used for termite or insect control, as a pesticide, insecticide, or a fungicide?


A. d-Limonene is used as both an active and inert ingredient in pesticide products, and as an ingredient in food products, soaps, and perfumes. As an active ingredient, it is used as an insecticide, insect repellent, and animal (dog and cat) repellent. As a pesticide inert ingredient is used as a solvent or fragrance. [EPA]

Our Florida Orange Oil & d-Limonene is 100% Natural. It does not contain any additives, such as colors, soaps, emulsifiers, surfactants or water. It is the same oil used for termite and insect control, however, as all GreenTerpene Products are branded and marketed as all-purpose cleaners and not as pesticides, fungicides, or insecticides, we cannot provide any further information regarding such use, including methods of application, dilution ratios, how-to info, etc...



Q. Can GreenTerpene d-Limonene or GreenTerpene Orange Oil for weed control (as an herbicide)?


A.Our Florida Orange Oil & d-Limonene is 100% Natural. It does not contain any additives, such as colors, soaps, emulsifiers, surfactants or water. It is the same oil used as an herbicide, however, as all GreenTerpene Products are branded and marketed as all-purpose cleaners and not as herbicides, we cannot provide any further information regarding such use, including methods of application, dilution ratios, how-to info, etc...

d-Limonene is not registered for food or feed crop uses as an active ingredient, but can be used on compost and manure. As an inert ingredient, d-Limonene can be applied to agricultural crops. [EPA]



Q. Is there anywhere in the United States where d-Limonene is exempt from EPA registration as an active ingredient?


A.  No, d-Limonene is subject to registration by the EPA for use as an active ingredient in a pesticide.

The EPA has granted d-Limonene an exemption from the requirement of a tolerance when it is an inert ingredient used as a solvent or fragrance in pesticide formulations.[EPA]



Q. Is there anywhere in the United States where d-Limonene is exempt from EPA registration when used as an inert ingredient?

A.  In 40 CFR Part 180, the US EPA has granted d-Limonene an exemption from tolerance when used as an inert in pesticide formulations. This means that the EPA has examined the possible environmental and health impacts of using d-Limonene as a carrier or fragrance in pesticides and found that no risks exist for this usage. This allows d-Limonene to be used in pesticide formulations at any level without having to meet any residue tolerances requirements.

In many cases d-Limonene can act as the majority carrier solvent for pesticides as they are applied to crops and animals. While this does not allow for the claim of d-Limonene as the actual pesticide, it does allow for formulations to be made with d-Limonene as the carrier, or as a fragrance, instead of other solvents which may accumulate in the environment. In this manner, pesticide formulation using d-Limonene may be more environmentally preferable than other formulations. [EPA]



Q. Is d-Limonene listed on California Proposition 65 toxic substance list?


A. No, d-Limonene is not listed on California Proposition 65 toxic substance list.



Q. Do GreenTerpene products contain ozone-depleting substances? Are GreenTerpene products manufactured with any ozone-depleting substances?


A. d-Limonene does not contain nor is it manufactured with any Class I or II ozone-depleting substances listed under the United States Clean Air Act of 1990.



Q. Since all GreenTerpene products are Food Grade, may they be ingested?


A. The FDA (Food and Drug Administration) list d-Limonene as GRAS (Generally Recognized As Safe) in 21 CFR section 182.20 and 182.6 for use as a flavoring agent and can be found in common food items. It is present in baked goods, ice cream products, gelatins, puddings and chewing gum at levels ranging from 68 to 2300 ppm.[EPA]

In addition, GreenTerpene High Purity d-Limonene, Grapefruit, Tangerine, Lime sweet, Lime sour, Lemon, Peppermint, Eucalyptus, and Clove Terpenes all fall under this designation.

GreenTerpene Products do not contain any additives, colors, soaps, emulsifiers, surfactants, or water. However, as all GreenTerpene Products are branded and marketed as all-purpose cleaners and not as food additives, we cannot provide any further information regarding that use, such as methods of application, dilution rates, etc...

Q. Is d-Limonene safe to use around children? Should special considerations be taken for infants and children?

A. At this time, there is no concern for potential sensitivity to infants and children.  Based on the data from the study reviewed in the RED (EPA, 1994) and the various teratogenicity and embryotoxicity studies reviewed in the WHO study (1998), it is now again concluded that limonene is not a developmental toxicant. Therefore, a safety factor analysis has not been used to assess the risk.  For the same reason, the additional tenfold safety factor is unnecessary, and has been removed. [EPA]



Q. What is Technical Grade d-Limonene? Does GreenTerpene sell Technical Grade d-Limonene?

A. Technical Grade d-Limonene and GreenTerpene Food Grade or High Purity d-Limonene vary immensely. Technical Grade d-Limonene is produced by steam distilling a puree of spent orange peels (peels that have already had Orange Oil and d-Limonene extracted from them) and water. (See diagram below) Technical grade d-Limonene is often un-standardized and therefore d-Limonene contents may vary from 60%-90% d-Limonene. Technical Grade d-Limonene can at times also have a stale or foul smell, and may vary in color from pale-yellow to yellow to amber-yellow (Gardner Color). As a result, GreenTerpene does not to offer technical grade d-Limonene.
