It can absorb body odor well. It has a natural source and can be used in various formulas such as bar soap, liquid soap, shampoo, roll-on cream or deodorant spray.

Zinc Ricinoleate (30% Solution)

It can absorb body odor well. It has a natural source and can be used in various formulas such as bar soap, liquid soap, shampoo, roll-on cream or deodorant spray.

The product is manufactured to be comparable to the TEGODEO A30 but is not manufactured by the same manufacturer and is not related in any way.

Zinc Ricinoleate in liquid form is dispersible in water.

It is stable in formulas with pH values in the range of 7.5-11.

If you want the formula to be clear:

1-4% Zinc Ricinoleate (30% Solution)

3-7% Ultra Solve

5=20% Propylene Glycol or Butylene Glycol or Ethyl Alcohol

0.1% Disodium EDTA (in case of formula pH less than 8) or Tetrasodium EDTA (in case of pH over 8)

What is Zinc Ricinoleate?

Zinc ricinoleate is a salt of zinc and ricinoleic acid, the primary fatty acids found in castor oil, extracted from the seeds of the castor plant ( Ricinus communis ). When ricinoleic acid is denatured with zinc, the resulting waxy solid is used as an important ingredient in skin care and personal care products, particularly deodorants.

Role in cosmetics

1. Deodorizing Agent

   • Zinc ricinolate is commonly used in deodorants and foot care products because of its antiperspirant properties.

   • The mechanism of action is to capture and hold on to molecules that cause unpleasant odors, such as volatile sulfur compounds, rather than masking the odor with perfume, but actually absorbing the odor.

2. Stabilizer and Emulsifier

   • Despite its reputation as a deodorant, zinc ricinolate can play a role in helping to stabilize product emulsions.

   • They are often used in combination with surfactants or co-emulsifiers to enhance the stability and performance of formulations.

3. Application concentration and formula characteristics

   • The amount commonly used in cosmetic formulations is between approximately 0.5% and 3% (depending on the type of product).

   • They are generally formulated in solutions or emulsions to disperse well and act effectively.

safety

1. Low irritant potential

   • At normal concentrations, zinc ricinolate is considered safe and is unlikely to cause irritation.

   • However, standard formulation development guidelines should be followed and the safety of the final product tested before it is marketed.

2. Regulatory Acceptance

   • Zinc ricinolate is permitted for use in cosmetics in many countries (e.g., the European Union and the United States) without specific restrictions.

   • It is not classified as a hazardous substance when used under normal conditions of a cosmetic formula.

3. Allergens and Sensitization

   • Currently, there are no widespread reports that zinc ricinolate is an allergen or a trigger for allergic reactions.

   • Those with sensitive skin or those with particularly thin skin issues should test the product before full use.

summarize

Zinc ricinolate has gained popularity in cosmetic products, particularly deodorants, due to its ability to bind and neutralize odor-causing molecules rather than masking them with a pleasant fragrance. This adsorption mechanism allows for effective and long-lasting odor reduction. Research and practical use have shown that, when used in appropriate concentrations, it is relatively gentle on the skin and safe for most people, which is why it is likely to remain in high demand in the consumer market looking for effective and gentle deodorants.
