10. Remark

Basic knowledge of Carrageenan

  • Natural polysaccharides derived from red algae that live mainly along rocks off the Atlantic coast
  • Food additives that are often used in ice cream and beverages
  • the primary role is increasing viscosity
  • It became known 600 years ago when the residents of the southern Irish coastal town of Karaginan used red seaweed as a raw material for producing Carrageenan. It was named after the village.

How Carrageenan Is Made

  • The collected red algae are extracted from hot water or an alkaline solution and then refined.
  • It dissolves entirely at 80 to 85 degrees and becomes gel at 50 to 55 degrees when cooled.
  • And this gel doesn't change its viscosity over time.

Is Carrageenan a carcinogen?

  • Carrageenan gets absorbed well in the intestine, but no metabolic process occurs in cells.
  • Therefore, the undissolved Carrageenan begins to accumulate in cells, at which time the self-collapse mechanism of Carrageenan occurs.
  • There are reports that repeating this can cause ulcers in the digestive system and develop into cancer.
  • So there was once a controversy in the United States and Japan that it is a carcinogen.
  • However, in 2001, the Joint FAO/WHO Expert Committee on Food Additives(JECFA) verified the safety of Carrageenan
  • In 2013, the U.S. Department of Agriculture (USDA) treated Carrageenan as a safe food additive.
  • The International Agency for Research on Cancer (IARC) classified Carrageenan as "Group 3" rather than a human carcinogen.
    • Group3 is an "unclassified substance on the carcinogenicity of the human body, " which means that it is unreliable because of insufficient human research data and animal testing results.
  • However, it is not recommended for infants and toddlers with slow bowel activity

What are the effects of Carrageenan?

  • Anti-oxidizing to prevent skin aging
  • Preventing the skin from getting dry
  • Helps soothe sensitive skin
  • It acts as a thickener (boosting viscosity)

Misleading Claims in Microneedle Skincare Products: 82 Cases Identified

     Recently, microneedle skincare products have gained significant popularity, but Korea’s Ministry of Food and Drug Safety (MFDS) has uncovered that over 80% of these products being sold online are making false or exaggerated claims. After reviewing 100 online posts, the MFDS found that 82 of them violated Korea’s cosmetics regulations, leading to requests for the posts to be blocked by the Korea Communications Standards Commission. The misleading advertisements primarily claimed that microneedles could penetrate deep into the skin layers or promised immediate pore reduction, both of which are not scientifically validated for general cosmetic products. Microneedles are a medical technology designed to deliver substances into the deeper layers of the skin, typically used in drugs and medical devices. However, in the cosmetics industry, these products generally do not have the same capabilities. Some companies falsely advertised their products as having effects similar t...

It is called a Mixed sunscreen or a Combined sunscreen, and these days, many brands are developing products like this. Through this post, let's find out what inorganic and organic sunscreens are, and what sunscreens are most suitable for one to use. The difference between inorganic and organic sunscreen.
