In order to assess the quality of marketed cold perms, we purchased seventy eight commercial samples from cosmetic stores Taiwan area and forty two samples from beauty salons within Taipei from July 1993 to June 1994. The variables examined for both the first and the second lotion of cold perm ncluded: appearance, pH value, identification and determination of essential ingredients while the alkalinity was inclouded for the first lotion only. The results indicate that as high as 88.3% of the samples violated the relative regulations. Among those analyzed, many unqualified samples were found to contain chemicals not included in the original formulation presented for license application. Furthermore, it is worth while to note that two samples were sold without license. |
