1 LEAD IN YOUR LIPSTICK: A Journal appraisal

2 introduction Lead used as a coloring element in ceramic glazes
traditional base metal for water pipes basically taken up by ingestion uptake of food (65%) water (20%) air (15%) significant level of lead in the blood is about 10 microgram/dL At higher levels, ~25 micrograms/dL, there is high possibility of damage to kidneys and the nervous system Symptoms may include pain, numbness or tingling of the extremities, muscular weakness, headache, abdominal pain, memory loss, miscarriage or premature birth in pregnant women, and fatigue Although lead is an element found naturally on Earth, human activity such as mining, burning fossil fuels and manufacturing has caused its vast spread. It is used as a coloring element in ceramic glazes, and in wicks of candles. It is the traditional base metal for water pipes. Previously, lead was used in gasoline but this was recently phased out. Due to contamination of soil by lead paints and corroded pipes, food such as fruit, vegetables, meats, grains, seafood, soft drinks and wine may contain significant amounts of lead. Since pipes were originally made of lead, their corrosion can lead to contamination of drinking water especially when water is slightly acidic. Lead is basically taken up by ingestion. It can enter the human body through uptake of food (65%), water (20%) and air (15%). Lead poisoning occurs when lead builds up in the body, often over a period of months or years. The significant level of lead is about 10 microgram/dL since at this level, damage starts to arise, especially in children. At higher levels, ~25 micrograms/dL, there is high possibility of damage to kidneys and nervous system in both children and adults. Very high lead levels may cause seizures, unconsciousness and possibly death. Signs and symptoms usually don't appear until dangerous amounts have accumulated. Exposure to amounts of lead too low to cause symptoms in the short term may increase the risk of high blood pressure and future risk for mental decline. Symptoms may include: Pain, numbness or tingling of the extremities Muscular weakness Headache Abdominal pain Memory loss Mood disorders Reduced sperm count, abnormal sperm Miscarriage or premature birth in pregnant women Fatigue

3 In the news: Lead contamination
Started 3 years ago Mattel (toy company) recalled more than 18 million products after high lead content was found in their products in (August 2007) In October 2007, Campaign for Safe Cosmetics released a report which revealed trace amounts of lead among commercially-available lipstick brands lead levels exceeding USFDA’s upper limit for candy, 0.1ppm The mission to identify other commercially available products with significant lead content started about 3 years ago. In August 2007, toy company Mattel recalled more than 18 million products after high lead content was found in their toys that were subcontracted in China. Furthermore, in October 2007, Campaign for Safe Cosmetics released a report which revealed trace amounts of lead among commercially-available lipstick brands. The group reported these brands as having lead levels exceeding USFDA’s upper limit for candy, 0.1ppm. This news alarmed many, particularly the media, as the companies involved are top cosmetic companies in the United States.

4 The research question Is there a significant amount of lead among commercially available lipstick brands that can pose health risks? This leads us to our research question: Is there a significant amount of lead among commercially available lipstick brands that can pose health risks?

5 objectives To identify the allowable levels of lead according to drug authorities such as FDA To identify commercial brands of lipstick with significant lead content To compare the relative lead content in lipsticks with lead To determine if the use of the said products has already caused hazard to human health The following are the objectives: To identify the allowable levels of lead according to drug authorities such as FDA To identify commercial brands of lipstick with significant lead content To compare the relative lead content in lipsticks with lead To determine if the use of the said products has already caused hazard to human health

6 Lead in Cosmetics Summary of RRL

7 Allowable Levels of Lead in Cosmetics
Currently no lead content limit set by FDA Campaign for Safe Cosmetics, 2007 FDA limit of lead in candy: 0.01 PPM 1/3 of lipsticks in the market: PPM FDA study in 2009 Lipsticks in the market: PPM Lipsticks should not be compared to candies because they are not ingested. Currently, the US Food and Drug Administration (FDA) has not set a limit for lead as a contaminant in cosmetics, particularly lipsticks. A private group (Campaign for Safe Cosmetics, 2007), however, has set out to evaluate the lead content of several lipsticks based on the acceptable FDA limit of lead in candy, which is 0.01 PPM. The results of their study show that one-third of lipsticks in the market have levels of lead exceeding those of the allowable limit for candy ( ppm). A new study by the FDA (Hepp, Mindak and Cheng, (2009) also showed that the levels in the CSC study were underestimated and that the levels of lead in some lipsticks range from 0.09ppm to 3.06ppm. Comparing the levels of lead in lipsticks is not practical, however, according to the FDA, as lipsticks are not meant for ingestion, unlike candies (Al-Saleh, Al-Enazi & Shinwari, 2009), and are only applied topically.

8 Allowable Levels of Lead in Cosmetics
FDA has set a lead content limit as an impurity in the color additives used in cosmetics 10-20 PPM: safe and acceptable BFAD statement Maximal allowable lead limit in cosmetics: 20 PPM Based on consolidation of data from other ASEAN countries While the FDA has no limit on lipsticks, it has however, imposed a specific limit for lead content as an impurity in the color additives used in lipsticks or cosmetics in general. Color additives that have a lead content of ppm, according to the article by Al-Saleh et al (2009), are safe and acceptable by FDA standards. The Bureau of Food and Drugs in the Philippines, on the other hand, has issued a circular (No ) issuing a statement that the maximum allowable limit of lead in cosmetics is 20 ppm. This statement was made after the consolidation of data from other ASEAN member countries.

9 20 lipsticks of varying brands Highest: Cover Girl brand, 3.06 PPM
Comparison of Commercial Brands of Lipsticks with Significant Lead Content FDA study in 2009 20 lipsticks of varying brands Highest: Cover Girl brand, 3.06 PPM Lowest: Avon brand, 0.09 PPM Average level: 1.07 PPM In the study done by Hepp, Mindak and Cheng (2009), 20 lipsticks of varying brands were found to have lead levels ranging from ppm. Among the 20 lipsticks, it is Cover Girl who has the highest level of lead, with 3.06 ppm. Avon has the lowest level of lead, on the other hand, with 0.09 ppm. On the average, lipsticks included in this study had a lead level of 1.07 ppm. Below is a table of the different brands.

12 Comparison of Commercial Brands of Lipsticks with Significant Lead Content
Study by Al-Saleh et al, 2009 48 lipsticks from 26 brands Lead content range: PPM There were 3 outliers in the data Without outliers: PPM Only 2 brands above the 20 PPM limit All 5 lipsticks that exceeded the limit: from China Lipsticks with shimmers: PPM All exceeded the 0.1 PPM limit in candy In the study by Al-Saleh, Al-Enazi & Shinwari (2009), 48 lipsticks from 26 brands were bought from a 2-riyals store and analyzed. Analysis of their raw data showed that the levels of lead in their lipstick samples ranged from 0.27 to 3760 PPM. Removal of three outliers, however, adjusted the range to 0.27–36.90 PPM, with only two brands exhibiting lead levels above 20 PPM or the FDA limit for lead as an impurity. These two brands were noted to have originated from China as well as the other three outliers that exhibited lead levels as high as 3760 ppm. Lipsticks with shimmers were also noted to have high levels of lead in them (0.33–3760 PPM). All lipsticks included in the study, however, also exceeded the 0.1 PPM US FDA permissible lead level in candy, which was the standard used by the CSC in their study.

13 Effect of Cosmetics with Lead to Human Health
Inter-organization Programme for the Sound Management of Chemicals, 1998 Allowable blood levels of lead: <20 µg/dl Allowable levels for children: <10 µg/dl This amount can already lead to a 2.5-point decrease in intelligence quotient of IQ According to article by the Inter-organization Programme for the Sound Management of Chemicals (1998), the allowable blood levels of lead are limited to <20 µg/dl in the general population. In the United States, the allowable level for children is <10 µg/dl as this amount can already lead to a 2.5-point decrease in intelligence quotient of IQ.

14 Nervous system: overt clinical encephalopathy 100-120 µg/dl
Kidney: atrophy and interstitial nephritis 40-100 Gastrointestinal: colic 40-60 Formation of blood cells: anemia 50 Reporudctive system: hypospermia, testicular atrophy 40-50 Nervous system: IQ/learning disruption, sensory system deficits 40 Heart and Blood Vessels: Hypertension <7 Formation of blood cells: biochemical (enzyme changes) 3-30 The blood lead levels presented in this table can affect certain organs in adults.

15 Effect of Cosmetics with Lead to Human Health
Inter-organization Programme for the Sound Management of Chemicals, 1998 There is no exposure level below which lead appears to be safe Children are more susceptible to the toxic effects of lead due to their behavior and stage of development Blood lead levels as low as 10 µg/dl can hamper blood cell formation and affect one’s IQ or cause some form of learning disruption Higher levels may cause colic, encephalopathy, renal atrophy, and interstitial nephritis The article mentions, however, that there is no exposure level below which lead appears to be safe and that children are more susceptible to the toxic effects of lead due to their behavior and stage of development. As mentioned, blood lead level in children as low as less than 10 µg/dl can hamper blood cell formation and affect one’s IQ or cause some form of learning disruption. Similar to adults, however, higher levels may cause colic, encephalopathy, renal atrophy, and interstitial nephritis as well.

16 Effect of Cosmetics with Lead to Human Health
American Academy of Child and Adolescent Psychiatry, 2006 Lead exposure to children: paint, water, soil Center for Disease Control About 6 percent of children aged 1-2 years old have toxic blood lead levels According to the American Academy of Child and Adolescent Psychiatry (2006), almost all children in the United States have been exposed to lead, commonly from paint, water, or soil. The Center for Disease Control (CDC) states that about 6 percent of children aged 1-2 years old have toxic blood lead levels.

17 Effect of Cosmetics with Lead to Human Health
Lead exposure during pregnancy Lead in the body are mainly stored in the bone These stores may be mobilized due to hormonal effects in pregnancy Lead readily crosses the placental barrier and may affect the fetus Pregnant women may not manifest symptoms but their future children could be affected via prenatal exposure As women predominantly use lipsticks, lead exposure during pregnancy is also a viable concern. Lead in the body are mainly stored in the bone and these stores may be mobilized due to hormonal effects in pregnancy. Lead also readily crosses the placental barrier and may affect the fetus. Thus childhood exposure of women may not manifest in them specifically but could affect their future children via prenatal exposure.

18 Effect of Cosmetics with Lead to Human Health
Currently FDA assessment of lipsticks tested Lead content levels are safe, not a concern Based on the premise that lipstick is for topical use only Majority are below the recommended limit given by public health officials, 10 PPM Currently, however, the FDA has assessed that the lead available in the lipsticks they have tested are safe and should not be a cause for concern. Their statement is based on the premise that lipstick is for topical use only and that majority of them are below the recommended limit given by public health officials (Health Canada, 2009), which is 10ppm.

19 Effect of Cosmetics with Lead to Human Health
Study by Al-Ashban et al, 2002 Blood analyses of regular kohl users revealed a high lead concentration and relatively low hemoglobin levels Kohl was also estimated to have lead levels as high as 52.3% The same cannot be said for other cosmetics such as kohl, however. In a study by Al-Ashban, Aslam, and Shah (2002), it was found that the blood analyses of regular kohl users revealed a high lead concentration and relatively low hemoglobin levels. Kohl, in the study, was also estimated to have lead levels as high as 52.3%.

20 Effect of Cosmetics with Lead to Human Health
Study by Al-Ashban et al, 2002 Blood lead levels Control group mean value: 0.9µg/dl ± 0.43 Kohl users group mean value: 17.65µg/dl ±2.29 Hemoglobin levels Control group mean value: 14.02g/dl ± 0.21 Kohl users group mean value: 12.22g/dl ± 0.37 The study by Al-Saleh et al (1999) supports the findings made by Al-Ashban et al (2002). For blood lead levels, the control group had a mean value of 0.9µg/dl ± 0.43 while the Kohl users group had a mean of 17.65µg/dl ±2.29. As for the hemoglobin levels, the control group had a mean of 14.02g/dl ± 0.21 while the Kohl users group had a lower mean at 12.22g/dl ± The article by Al-Saleh et al (1999) also supports the findings made by Al-Ashban et al (2002), particularly for blood lead levels.

21 Discussion

22 Objective 1: To identify the allowable levels of lead according to drug authorities such as FDA
USFDA – no limit for lead as a contaminant in cosmetics as of now Impurities in color additives in cosmetics – 20ppm Campaign for Safe Cosmetics Set limit to 0.1ppm based on permissible limit of lead in candies BFAD (FDA Philippines) Issued a circular (No ) for a maximum allowable limit of lead in cosmetics to 20ppm The USFDA currently has not set a limit for lead as a contaminant in cosmetics. However there are specifications set for impurities in color additives used in cosmetics. The limit of lead levels in color additives approved for use in cosmetics is set at 20 ppm. The Campaign for Safe Cosmetics, a non-profit coalition, set the limit to 0.1pm, adapted based on the permissible limit of lead in candies following the assumption that lipsticks can be ingested. However, there has been an argument that 0.1 ppm is not valid as a limit level for lipsticks since they are not intended for ingestion and consumption on a regular basis and that the amount taken by the body is small. FDA Philippines has set an allowable limit of lead in cosmetics to 20ppm.

23 Hepp, Mindak and Cheng (2009)
Objectives 2 and 3: To identify commercial brands of lipstick with significant lead content; To compare the relative lead content in lipsticks with lead Hepp, Mindak and Cheng (2009) 20 lipsticks of varying brands found to have lead levels ppm Covergirl: highest level (3.06ppm) Avon: lowest level (0.09ppm) Average lead level of all lipsticks: 1.07ppm In a study done by Hepp, Mindak and Cheng (2009), 20 lipsticks of varying brands were found to have lead levels ranging from ppm. Among the 20 lipsticks, it is Cover Girl which has the highest level of lead, with 3.06 ppm. Avon has the lowest level of lead, on the other hand, with 0.09 ppm. On the average, lipsticks included in this study had a lead level of 1.07 ppm.

24 Objectives 2 and 3: To identify commercial brands of lipstick with significant lead content; To compare the relative lead content in lipsticks with lead Al Saleh et al. (2009) 72 lipstick samples turned positive for lead, with levels ranging from ppm Exclusion of three outliers dropped upper value from 3760 to Since no valid reasons to exclude outliers, four brands are recognized as having levels beyond 20ppm All samples with lead content exceeding 20ppm obtained from China In a study conducted by Al-Saleh et.al., all of the 26 brands consisting of 72 lipstick samples from China, USA, France, Italy, Taiwan and Germany turned out to be positive for lead. Lead levels range from ppm. These levels however have 3 outliers. Exclusion of these three outliers would drop the upper value of the range from 3760 ppm to ppm, with only two values above the limit set by the USFDA. Since there are no valid reasons to exclude the outliers, ultimately, 4 brands are recognized as having levels beyond the 20 ppm limit. These lipstick samples were obtained from China.

25 Objective 4: To determine if the use of the said products has already caused hazard to human health
Lead in lipsticks might not cause an immediate health problem However, it can accumulate due to repeated application and may result in cumulative toxicity Dependent on the frequency of application which varies from one woman to another The consequences of these products can only be properly verified by conducting population risk assessment exposure study FDA has assessed that the lead available in the lipsticks they have tested are safe and should not be a cause for concern lipstick is for topical use only and that majority of them are below the recommended limit given by public health officials Although overexposure to lead in general causes many health problems, there have been no accounts of effects as a direct consequence of lipstick use. As discussed in the study by Al-Saleh et.al.,lead in lipsticks might not cause an immediate health problem. However, it can accumulate due to repeated application and may result in cumulative toxicity. This is also dependent on the frequency of application which varies from one woman to another. The consequences of these products can only be properly verified by conducting population risk assessment exposure study. Currently, however, the FDA has assessed that the lead available in the lipsticks they have tested are safe and should not be a cause for concern. Their statement is based on the premise that lipstick is for topical use only and that majority of them are below the recommended limit given by public health officials.
