Gellan Gum

The Basics On Gellan Gum

What is Gellan Gum?

A water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea.

What are other names for Gellan Gum?

GELLAN, GELLAN GUM, and GUM GELLAN

What is Gellan Gum used for?

Gellan gum is widely used in shampoos, body washes, sprayable sunscreens, etc. Gellan gum acts as emulsion stabilizer by preventing the separation of oil and water. In cosmetic formulations, gellan gum acts as suspending agent by stabilizing the emulsion and keeping it uniform against temperature fluctuations.

Gellan Gum During Pregnancy

What we know about using Gellan Gum while pregnant or breastfeeding

Limited information available.

A 3-generation reproductive toxicity study was performed in which albino rats were fed dietary levels of O, 0.25, and 0.5 g/kg BWd xanthan gum.61 Ten males and 20 females were used for the first generation, and 20 males and 20 females were used in the next 2 generations. Rats were mated to produce 2 litters per generation, and the successive generations were selected from weanlirws of the second litter. Survival and reproductive parameters were similar for treated and control parental rats. Body weights of treated parental rats were slightly decreased compared to controls in each generation. There were no significant differences in developmental parameters between test and control litters, and no malformations were observed in any of the offspring. Gellan gum. Groups of 25 gravid female Sprague Dawley rats were fed a diet containing 0%, 2.5%, 3.8%, or 5.0% gellan gum (varied degree of acetylation; 58.5% polysaccharide) on days 6 to 15 of gestation. 9 No fetotoxic or teratogenic effects were reported (no other details were provided). Beta-glucon. A developmental study was performed with 0%, 5%, or 15% beta-glucan (as curdlan) with a control group of 40 male and 80 female CD rats and test groups of 20 male and 40 female rats.42 The animals, which were mated twice, were fed the test diet throughout the study. Twenty of the treated dams nursed their own litters; the other 20 treated dams switched litters with the control dams so that treated animals would nurse control pups and control animals would nurse test pups. The Fla offspring were killed prior to the second mating. No changes in mortality, behavior, or appearance were observed. Male sires of the 15% beta-glucan group had decreased growth rates compared to controls, and males and females ofthe group had decreased feed consumption. At birth, there were no differences in fertility or lactation among the groups, and no abnormalities were reported. However, survival of the Fla, but not the Fib, pups ofthe 5% group was statistically significantly decreased compared to controls. Weight gain of all F la litters of treated dams that nursed their own pups was statistically significantly decreased compared to controls; for the Fib litters, the difference was statistically significant only in the 15% group. Statistically significant decreases in weight gain were also observed for pups of treated dams that were nursed by control dams, but the effect was reduced. Statistically significant decreased weight gain at some intervals was also observed for control pups nursed by treated dams. A no observable effect level (NOEL) was not established. The researchers also examined whether there would be decreased weight gain by the pups if dosing was discontinued during lactation. The protocol was similar to that just described, except that all groups consisted of 20 male and 40 female CD rats, and there was no crossover at lactation. Weight gain by all pups during lactations was similar, although the researchers did state that the pups could have consumed parental diet from day The NOEL for parental toxicity and embryotoxicity was 15% beta-glucan. A 3-generation reproductive study was performed in which groups of 20 male and 40 female CD rats were fed a diet containing 1%, 5%, or beta-glucan (as curdlan) for 100 days.4 The Fo parents were mated twice, and the number of parents was halved after weaning of the first litter. The Fl parents were mated 3 times and the F2 parents were mated twice. The Fib and F2b litters were used to produce the next generation. After the third mating of the F, parents, half of the F I dams were killed on day 13 of gestation, and the remaining dams were killed on day 20 of gestation. Mean growth and feed consumption were slightly decreased in male parental rats of the Fo and Fl generations of the 15% group. No gross or microscopic changes were observed in F2 parents. No treatment-related effects on reproductive and developmental parameters were observed, but BWs of pups in almost all litters in all generations were statistically significantly decreased during lactation in the group. Biologically significant differences in BWs were not seen in litters of the other dose groups. No gross or microscopic lesions were observed in the F3b pups of the 15% group. In the F, parents killed after the third mating, no reproductive or developmental effects were observed. Mean fetal weights in all groups were statistically significantly decreased compared to controls; however, there was no dose response. The NOEL for parental animals was 5%, based on decreased growth and increased cecal weights at beta-glucan, and the NOEL for embryotoxicity

General safety info about Gellan Gum from CIR

The Cosmetic Ingredient Review Expert Panel assessed the safety of 34 microbial polysaccharide gums for use in cosmetics. finding that these ingredients are safe in cosmetic formulations in the present practices of use and concentration. The microbial polysaccharide gums named in this report have a variety of reported functions in cosmetics, including emulsion stabilizer, film former, binder, viscosity-increasing agent, and skin-conditioning agent. The Panel reviewed available animal and clinical data in making its determination of safety.
