When it comes to living a healthy and natural lifestyle, what you put on your body is just as significant as what you put in your body. Your skin is the largest organ of your body and since it is porous, it absorbs whatever you put on it.
A study published in the American Journal of Public Health looked into the skin’s absorption rates of chemicals found in drinking water. It showed that the skin absorbed an average of 64% of total contaminant dosage.1Other studies found the face to be several times more permeable than broad body surfaces and an absorption rate of 100% for underarms and genitalia.2 And another peer-reviewed study showed 100% absorption for fragrance ingredients.3
It is easy to see that what we use on our skin ends up inside our bodies. So it is important to pay close attention to the ingredients in our skin care products. If the products you use contain harmful ingredients such as harsh, toxic chemicals, colors, and fragrances, those ingredients make their way into your body, your blood and lymphatic system. The majority of mainstream body care products contain a cocktail of carcinogenic chemicals, allergens, and irritants.
To eliminate a lot of toxic chemicals, preservatives, and fragrances that are harmful to our bodies, choose certified organic and natural skin care products. It is important to read labels and become educated about what ingredients to avoid when selecting body care products. A good motto to go by is if you can’t pronounce it or have only seen it in chemistry class, don’t use it! Petroleum derivatives, preservatives, synthetic fragrances and dyes go by many names. A few examples of common ingredients to steer clear of are Cocoamidopropyl Betaine, Olefin Sulfonate, Sodium Luaroyl Sarcosinate, Potassium Cocoyl Glutamate, Sulfates, Parabens, and Phenoxyethanol. Following is an example of a mainstream product and the synthetic ingredients it contains:
Vaseline Intensive Care Dry Skin Lotion
Ingredients from packaging: ACTIVE INGREDIENT: ETHYLHEXYL P-METHOXYCINNAMATE (SPF 5). OTHER INGREDIENTS: WATER, GLYCERIN, STEARIC ACID, GLYCOL STEARATE, SUNFLOWER SEED OIL, SOYA STEROL, LECITHIN, TOCOPHERYL ACETATE, RETINYL PALMITATE, DIMETHICONE, GLYCERYL STEARATE, CETYL ALCOHOL, TEA, MAGNESIUM ALUMINUM SILICATE, FRAGRANCE, CARBOMER, STEARAMIDE AMP, CORN OIL, METHYLPARABEN, DMDM HYDANTOIN, IODOPROPYNYL BUTYLCARBAMATE, DISODIUM EDTA, PG, BHT, TITANIUM DIOXIDE, YELLOW NO. 10.
By selecting organic and natural products for yourself and your family, you are taking a big step toward a healthier lifestyle. The developing organs of babies and children are particularly sensitive to chemicals so it is especially important to use safe products for your youngsters. Down to Earth has a wide selection of natural and organic body care products. Look for even more in the near future as our team is working hard to ensure that DTE carries the purest products available
The WASH IN effect - very interesting
Abstract
Skin decontamination is a primary interventional method used to decrease dermal absorption of hazardous contaminants, including chemical warfare agents, pesticides and industrial pollutants. Soap and water wash, the most common and readily available decontamination system, may enhance percutaneous absorption through the "wash-in effect." To understand better the effect of soap-water wash on percutaneous penetration, and provide insight to improving skin decontamination methods, in vitro human epidermal penetration rates of four C(14) -labeled model chemicals (hydroquinone, clonidine, benzoic acid and paraoxon) were assayed using flow-through diffusion cells. Stratum corneum (SC) absorption rates of these chemicals at various hydration levels (0-295% of the dry SC weights) were determined and compared with the results of the epidermal penetration study to clarify the effect of SC hydration on skin permeability. Results showed accelerated penetration curves of benzoic acid and paraoxon after surface wash at 30 min postdosing. Thirty minutes after washing (60 min postdosing), penetration rates of hydroquinone and benzoic acid decreased due to reduced amounts of chemical on the skin surface and in the SC. At the end of the experiment (90 min postdosing), a soap-water wash resulted in lower hydroquinone penetration, greater paraoxon penetration and similar levels of benzoic acid and clonidine penetration compared to penetration levels in the non-wash groups. The observed wash-in effect agrees with the enhancement effect of SC hydration on the SC chemical absorption rate. These results suggest SC hydration derived from surface wash to be one cause of the wash-in effect. Further, the occurrence of a wash-in effect is dependent on chemical identity and elapsed time between exposure and onset of decontamination. By reducing chemical residue quantity on skin surface and in the SC reservoir, the soap-water wash may decrease the total quantity of chemical absorbed in the long term; however, the more immediate accelerated absorption of chemical toxins, particularly chemical warfare agents, may be lethal.
